    This study investigated whether selection using genotype information reduced the rate and level of true inbreeding, that is, identity by descent, at a selectively neutral locus as well as a locus under selection compared with traditional BLUP selection. In addition, the founder representation at these loci and the within-family selection at the nonneutral locus were studied. The study was carried out using stochastic simulation of a population resembling the breeding nucleus of a dairy cattle population for 25 yr. Each year, 10 proven bulls were selected across herds along with 100 dams from within each of 40 herds. Selection was performed using BLUP, marker-assisted, or gene-assisted selection for a trait with low heritability (h2 = 0.04) only expressed in females, mimicking a health trait. The simulated genome consisted of 2 chromosomes. One biallelic quantitative trait loci (QTL) with an initial frequency of the favorable allele of 0.1, and initially explaining 25% of the genetic variance as well as 4 markers were simulated in linkage disequilibrium, all positioned at chromosome 1. Chromosome 2 was selectively neutral, and consisted of a single neutral locus. The results showed that in addition to reducing pedigree-estimated inbreeding, the incorporation of genotype information in the selection criteria also reduced the level and rate of true inbreeding. In general, true inbreeding in the QTL was greater than pedigree-estimated inbreeding with respect to both the level and rate of inbreeding, as expected. Also as expected, true and pedigree-estimated inbreeding in the neutral locus were the same. Furthermore, after 25 yr, or approximately 5 generations, the pedigree-estimated level of inbreeding was reduced by 11 and 24% compared with BLUP in gene- and marker-assisted selection, respectively, and the level of true inbreeding in the QTL was reduced by 22 and 13%, respectively. The difference between selection scenarios was found to be caused by a larger number of

    Ongoing major advances in plant genotyping and phenotyping lead to a better understanding of genetic architecture of agronomical traits. In this context, it is important to develop decision support tools to help breeders in implementing marker-assisted selection (MAS) projects to assemble new allele combinations. Algorithms have been developed within an interactive graphical interface to (a) trace parental QTL alleles throughout selection generations, (b) propose strategies to select the best plants based on estimated molecular scores, and (c) efficiently intermate them depending on the expected value of their progenies. By investigating multi-allelic context and diverse pedigree structure, OptiMAS enables to assemble favorable alleles issued from diverse parents and further accelerate genetic gain.

  11. Efficiency of Marker-Assisted Selection in the Improvement of Quantitative Traits

    1990-01-01

    Molecular genetics can be integrated with traditional methods of artificial selection on phenotypes by applying marker-assisted selection (MAS). We derive selection indices that maximize the rate of improvement in quantitative characters under different schemes of MAS combining information on molecular genetic polymorphisms (marker loci) with data on phenotypic variation among individuals (and their relatives). We also analyze statistical limitations on the efficiency of MAS, including the detectability of associations between marker loci and quantitative trait loci, and sampling errors in estimating the weighting coefficients in the selection index. The efficiency of artifical selection can be increased substantially using MAS following hybridization of selected lines. This requires initially scoring genotypes at a few hundred molecular marker loci, as well as phenotypic traits, on a few hundred to a few thousand individuals; the number of marker loci scored can be greatly reduced in later generations. The increase in selection efficiency from the use of marker loci, and the sample sizes necessary to achieve them, depend on the genetic parameters and the selection scheme. PMID:1968875

    2015-01-01

    Sequencing of rice genome has facilitated the understanding of rice evolution and has been utilized extensively for mining of DNA markers to facilitate marker-assisted breeding. Simple sequence repeat (SSR) markers that are tandemly repeated nucleotide sequence motifs flanked by unique sequences are presently the maker of choice in rice improvement due to their abundance, co-dominant inheritance, high levels of allelic diversity, and simple reproducible assay. The current level of genome coverage by SSR markers in rice is sufficient to employ them for genotype identification and marker-assisted selection in breeding for mapping of genes and quantitative trait loci analysis. This review provides comprehensive information on the mapping and applications of SSR markers in investigation of rice cultivars to study their genetic divergence and marker-assisted selection of important agronomic traits.

    Rice tungro disease (RTD) is one of the destructive and prevalent diseases in the tropical region. RTD is caused by Rice tungro spherical virus (RTSV) and Rice tungro bacilliform virus. Cultivation of japonica rice (Oryza sativa L. ssp japonica) in tropical Asia has often been restricted because most japonica cultivars are sensitive to short photoperiod, which is characteristic of tropical conditions. Japonica1, a rice variety bred for tropical conditions, is photoperiod-insensitive, has a high yield potential, but is susceptible to RTD and has poor grain quality. To transfer RTD resistance into Japonica1, we made two backcrosses (BC) and 8 three-way crosses (3-WC) among Japonica1 and RTSV-resistant cultivars. Among 8,876 BC1F2 and 3-WCF2 plants, 342 were selected for photoperiod-insensitivity and good grain quality. Photoperiod-insensitive progenies were evaluated for RTSV resistance by a bioassay and marker-assisted selection (MAS), and 22 BC1F7 and 3-WCF7 lines were selected based on the results of an observational yield trial. The results demonstrated that conventional selection for photoperiod-insensitivity and MAS for RTSV resistance can greatly facilitate the development of japonica rice that is suitable for cultivation in tropical Asia.

    We used computer simulations to investigate to what extent true inbreeding, i.e. identity-by-descent, is affected by the use of marker-assisted selection (MAS) relative to traditional best linear unbiased predictions (BLUP) selection. The effect was studied by varying the heritability (h(2) = 0.04 vs. 0.25), the marker distance (MAS vs. selection on the gene, GAS), the favourable QTL allele effect (alpha = 0.118 vs. 0.236) and the initial frequency of the favourable QTL allele (p = 0.01 vs. 0.1) in a population resembling the breeding nucleus of a dairy cattle population. The simulated genome consisted of two chromosomes of 100 cM each in addition to a polygenic component. On chromosome 1, a biallelic QTL as well as 4 markers were simulated in linkage disequilibrium. Chromosome 2 was selectively neutral. The results showed that, while reducing pedigree estimated inbreeding, MAS and GAS did not always reduce true inbreeding at the QTL relative to BLUP. MAS and GAS differs from BLUP by increasing the weight on Mendelian sampling terms and thereby lowering inbreeding, while increasing the fixation rate of the favourable QTL allele and thereby increasing inbreeding. The total outcome in terms of inbreeding at the QTL depends on the balance between these two effects. In addition, as a result of hitchhiking, MAS results in extra inbreeding in the region surrounding QTL, which could affect the overall genomic inbreeding.

    Theoretical studies suggest that marker-assisted selection (MAS) has case-specific advantages over phenotypic selection (PHE) for selection of quantitative traits. However, few studies have been conducted that empirically compare these selection methods in the context of a plant breeding program. For direct comparison of the effectiveness of MAS and PHE, four cucumber (Cucumis sativus L.; 2n = 2x = 14) inbred lines were intermated and then maternal bulks were used to create four base populations for recurrent mass selection. Each of these populations then underwent three cycles of PHE (open-field evaluations), MAS (genotyping at 18 marker loci), and random mating without selection. Both MAS and PHE were practiced for yield indirectly by selecting for four yield-component traits that are quantitatively inherited with 2-6 quantitative trait loci per trait. These traits were multiple lateral branching, gynoecious sex expression (gynoecy), earliness, and fruit length to diameter ratio. Both MAS and PHE were useful for multi-trait improvement, but their effectiveness depended upon the traits and populations under selection. Both MAS and PHE provided improvements in all traits under selection in at least one population, except for earliness, which did not respond to MAS. The populations with maternal parents that were inferior for a trait responded favorably to both MAS and PHE, while those with maternal parents of superior trait values either did not change or decreased during selection. Generally, PHE was most effective for gynoecy, earliness, and fruit length to diameter ratio, while MAS was most effective for multiple lateral branching and provided the only increase in yield (fruit per plant).

    Current advances in sequencing technologies and bioinformatics revealed the genomic background of rice, a staple food for the poor people, and provided the basis to develop large genomic variation databases for thousands of cultivars. Proper analysis of this massive resource is expected to give novel insights into the structure, function, and evolution of the rice genome, and to aid the development of rice varieties through marker assisted selection or genomic selection. In this work we present sequencing and bioinformatics analyses of 104 rice varieties belonging to the major subspecies of Oryza sativa. We identified repetitive elements and recurrent copy number variation covering about 200 Mbp of the rice genome. Genotyping of over 18 million polymorphic locations within O. sativa allowed us to reconstruct the individual haplotype patterns shaping the genomic background of elite varieties used by farmers throughout the Americas. Based on a reconstruction of the alleles for the gene GBSSI, we could identify novel genetic markers for selection of varieties with high amylose content. We expect that both the analysis methods and the genomic information described here would be of great use for the rice research community and for other groups carrying on similar sequencing efforts in other crops.

  19. Association mapping and marker-assisted selection of the lettuce dieback resistance gene Tvr1

    PubMed Central

    2009-01-01

    Background Lettuce (Lactuca saliva L.) is susceptible to dieback, a soilborne disease caused by two viruses from the family Tombusviridae. Susceptibility to dieback is widespread in romaine and leaf-type lettuce, while modern iceberg cultivars are resistant to this disease. Resistance in iceberg cultivars is conferred by Tvr1 - a single, dominant gene that provides durable resistance. This study describes fine mapping of the resistance gene, analysis of nucleotide polymorphism and linkage disequilibrium in the Tvr1 region, and development of molecular markers for marker-assisted selection. Results A combination of classical linkage mapping and association mapping allowed us to pinpoint the location of the Tvr1 resistance gene on chromosomal linkage group 2. Nine molecular markers, based on expressed sequence tags (EST), were closely linked to Tvr1 in the mapping population, developed from crosses between resistant (Salinas and Salinas 88) and susceptible (Valmaine) cultivars. Sequencing of these markers from a set of 68 cultivars revealed a relatively high level of nucleotide polymorphism (θ = 6.7 × 10-3) and extensive linkage disequilibrium (r2 = 0.124 at 8 cM) in this region. However, the extent of linkage disequilibrium was affected by population structure and the values were substantially larger when the analysis was performed only for romaine (r2 = 0.247) and crisphead (r2 = 0.345) accessions. The association mapping approach revealed that one of the nine markers (Cntg10192) in the Tvr1 region matched exactly with resistant and susceptible phenotypes when tested on a set of 200 L. sativa accessions from all horticultural types of lettuce. The marker-trait association was also confirmed on two accessions of Lactuca serriola - a wild relative of cultivated lettuce. The combination of three single-nucleotide polymorphisms (SNPs) at the Cntg10192 marker identified four haplotypes. Three of the haplotypes were associated with resistance and one of them was always

  20. Expanding Possibilities for Intervention against Small Ruminant Lentiviruses through Genetic Marker-Assisted Selective Breeding

    2013-01-01

    Small ruminant lentiviruses include members that infect sheep (ovine lentivirus [OvLV]; also known as ovine progressive pneumonia virus/maedi-visna virus) and goats (caprine arthritis encephalitis virus [CAEV]). Breed differences in seroprevalence and proviral concentration of OvLV had suggested a strong genetic component in susceptibility to infection by OvLV in sheep. A genetic marker test for susceptibility to OvLV has been developed recently based on the TMEM154 gene with validation data from over 2,800 sheep representing nine cohorts. While no single genotype has been shown to have complete resistance to OvLV, consistent association in thousands of sheep from multiple breeds and management conditions highlight a new strategy for intervention by selective breeding. This genetic marker-assisted selection (MAS) has the potential to be a useful addition to existing viral control measures. Further, the discovery of multiple additional genomic regions associated with susceptibility to or control of OvLV suggests that additional genetic marker tests may be developed to extend the reach of MAS in the future. This review will cover the strengths and limitations of existing data from host genetics as an intervention and outline additional questions for future genetic research in sheep, goats, small ruminant lentiviruses, and their host-pathogen interactions.

    Prairie cordgrass (Spartina pectinata Bosc ex Link) is an indigenous, perennial grass of North America that is being developed into a cellulosic biomass crop suitable for biofuel production. Limited research has been performed into the breeding of prairie cordgrass; this research details an initial investigation into the development of a breeding program for this species. Genomic libraries enriched for four simple sequence repeat (SSR) motifs were developed, 25 clones from each library were sequenced, identifying 70 SSR regions, and primers were developed for these regions, 35 of which were amplified under standard PCR conditions. These SSR markers were used to validate the crossing methodology of prairie cordgrass and it was found that crosses between two plants occurred without the need for emasculation. The successful cross between two clones of prairie cordgrass indicates that this species is not self-incompatible. The results from this research will be used to instigate the production of a molecular map of prairie cordgrass which can be used to incorporate marker-assisted selection (MAS) protocols into a breeding program to improve this species for cellulosic biomass production.

    A marker-assisted background selection (MABS)-based gene introgression approach in wheat (Triticum aestivum L.) was optimized, where 97% or more of a recurrent parent genome (RPG) can be recovered in just two backcross (BC) generations. A four-step MABS method was developed based on ‘Plabsim’ computer simulations and wheat genome structure information. During empirical optimization of this method, double recombinants around the target gene were selected in a step-wise fashion during the two BC cycles followed by selection for recurrent parent genotype on non-carrier chromosomes. The average spacing between carrier chromosome markers was <4 cM. For non-carrier chromosome markers that flanked each of the 48 wheat gene-rich regions, this distance was ∼12 cM. Employed to introgress seedling stripe rust (Puccinia striiformis f. sp. tritici) resistance gene Yr15 into the spring wheat cultivar ‘Zak’, marker analysis of 2,187 backcross-derived progeny resulted in the recovery of a BC2F2∶3 plant with 97% of the recurrent parent genome. In contrast, only 82% of the recurrent parent genome was recovered in phenotypically selected BC4F7 plants developed without MABS. Field evaluation results from 17 locations indicated that the MABS-derived line was either equal or superior to the recurrent parent for the tested agronomic characteristics. Based on these results, MABS is recommended as a strategy for rapidly introgressing a targeted gene into a wheat genotype in just two backcross generations while recovering 97% or more of the recurrent parent genotype.

    Seedling selection identifies superior seedlings as candidate cultivars based on predicted genetic potential for traits of interest. Traditionally, genetic potential is determined by phenotypic evaluation. With the availability of DNA tests for some agronomically important traits, breeders have the opportunity to include DNA information in their seedling selection operations—known as marker-assisted seedling selection. A major challenge in deploying marker-assisted seedling selection in clonally propagated crops is a lack of knowledge in genetic gain achievable from alternative strategies. Existing models based on additive effects considering seed-propagated crops are not directly relevant for seedling selection of clonally propagated crops, as clonal propagation captures all genetic effects, not just additive. This study modeled genetic gain from traditional and various marker-based seedling selection strategies on a single trait basis through analytical derivation and stochastic simulation, based on a generalized seedling selection scheme of clonally propagated crops. Various trait-test scenarios with a range of broad-sense heritability and proportion of genotypic variance explained by DNA markers were simulated for two populations with different segregation patterns. Both derived and simulated results indicated that marker-based strategies tended to achieve higher genetic gain than phenotypic seedling selection for a trait where the proportion of genotypic variance explained by marker information was greater than the broad-sense heritability. Results from this study provides guidance in optimizing genetic gain from seedling selection for single traits where DNA tests providing marker information are available. PMID:27148453

    Aliphatic glucosinolates are the predominant sulfur-rich plant secondary metabolites in economically important Brassica crops. Glucosinolates and their hydrolysis products are involved in plant-microbe, plant-insect, plant-animal, and plant-human interactions. It is, therefore, important to manipulate glucosinolate profiles and contents in Brassica species. In this study, aliphatic glucosinolates were genetically manipulated through homoeologous recombination in backcross lines followed by marker assisted selection in B. rapa. A resynthesized B. napus line, from a cross between B. rapa and B. oleracea, was backcrossed with Chinese cabbage doubled haploid line, RI16. Marker assisted selection for non-functional gene was performed in each backcross generations. Advanced backcross progenies (BC3F2) were developed to identify homoeologous gene replacement and/or introgression. Reduction in 5C aliphatic glucosinolates (gluconapoleiferin, glucoalyssin, and glucobrassicanapin) was observed in BC3F2 progenies of the recurrent parent that carried the GSL-ELONG (-) gene. The GSL-ELONG (-) positive backcross progenies were also screened by the A-genome and BraGSL-ELONG gene specific marker, which linked with 5C aliphatic glucosinolates. The A-genome specific marker was absent in the plants of advanced backcross progenies which showed reduction in 5C aliphatic glucosinolates. The results suggest that the functional allele had been replaced by the non-functional GSL-ELONG (-) allele from B. oleracea. Some advanced backcross progenies (BC3F2) positive for the GSL-ELONG (-) allele and the A-genome specific SCAR marker BraMAM1-1 did not show reduction in 5C aliphatic glucosinolates, suggesting that GSL-ELONG (-) allele is recessive. Replacement of the functional locus in the A-genome by non-functional counterpart in the C-genome reduced the content of 5C aliphatic glucosinolates in B. rapa seeds with 20 μmol/g.

    Stripe rust disease is caused by the fungus Puccinia striiformis f. sp. tritici and severely threatens wheat worldwide, repeatedly breaking resistance conferred by resistance genes and evolving more aggressive strains. Wild emmer wheat, Triticum dicoccoides, is an important source for novel stripe rust resistance (Yr) genes. Yr15, a major gene located on chromosome 1BS of T. dicoccoides, was previously reported to confer resistance to a broad spectrum of stripe rust isolates, at both seedling and adult plant stages. Introgressions of Yr15 into cultivated T. aestivum bread wheat and T. durum pasta wheat that began in the 1980s are widely used. In the present study, we aimed to validate SSR markers from the Yr15 region as efficient tools for marker-assisted selection (MAS) for introgression of Yr15 into wheat and to compare the outcome of gene introgression by MAS and by conventional phenotypic selection. Our findings establish the validity of MAS for introgression of Yr15 into wheat. We show that the size of the introgressed segment, defined by flanking markers, varies for both phenotypic selection and MAS. The genetic distance of the MAS marker from Yr15 and the number of backcross steps were the main factors affecting the length of the introgressed donor segments. Markers Xbarc8 and Xgwm493, which are the nearest flanking markers studied, were consistent and polymorphic in all 34 introgressions reported here and are therefore the most recommended markers for the introgression of Yr15 into wheat cultivars. Introgression directed by markers, rather than by phenotype, will facilitate simultaneous selection for multiple stripe rust resistant genes and will help to avoid escapees during the selection process.

    Allelic diversity of HMW glutenin loci in several studies revealed that allelic combinations affect dough quality. Dx5 + Dy10 subunits are related to good baking quality and Dx2 + Dy12 are related to undesirable baking quality. One of the most regular methods to evaluate the baking quality is SDS-PAGE which is used to improve baking quality labs. Marker-assisted selection is the method which can recognize the alleles related to baking quality and this method is based on polymerase chain reaction. 10 pairs of specific primers related to Dx2, Dx2.1, Dx5, Dy10, and Dy12 subunits were used for recognizing baking quality of some wheat varieties and some mutant genotypes. Only 5 pairs of them could show the specific bands. All subunits were recognized by the primers except Dx2.1. Some of the primers were extracted from previous studies and the others were designed based on D genome subunits of wheat. SDS-PAGE method accomplished having confidence in these marker's results. To realize the effect of mutation, seed storage proteins were measured. It showed that mutation had effect on the amount of seed storage protein on the mutant seeds (which showed polymorphism).

    Genomic tools for watermelon breeding are becoming increasingly available. A high throughput genotyping system would facilitate the use of DNA markers in marker-assisted selection. DNA extraction from leaf material requires prior seed germination and is often time-consuming and cost prohibitive. In an effort to develop a more efficient system, watermelon seeds of several genotypes and various seed sizes were sampled by removing ⅓ or ½ sections from the distal ends for DNA extraction, while germinating the remaining proximal parts of the seed. Removing ⅓ of the seed from the distal end had no effect on seed germination percentage or seedling vigor. Different DNA extraction protocols were tested to identify a method that could yield DNA of sufficient quality for amplification by polymerase chain reaction. A sodium dodecyl sulfate extraction protocol with 1% polyvinylpyrrolidone yielded DNA that could be amplified with microsatellite primers and was free of pericarp contamination. In this study, an efficient, non-destructive genotyping protocol for watermelon seed was developed. PMID:23546952

    Experiments were conducted to identify blast-resistant fragrant genotypes for the development of a durable blast-resistant rice variety during years 2012-2013. The results indicate that out of 140 test materials including 114 fragrant germplasms, 25 differential varieties (DVs) harbouring 23 blast-resistant genes, only 16 fragrant rice germplasms showed comparatively better performance against a virulent isolate of blast disease. The reaction pattern of single-spore isolate of Magnaporthe oryzae to differential varieties showed that Pish, Pi9, Pita-2 and Pita are the effective blast-resistant genes against the tested blast isolates in Bangladesh. The DNA markers profiles of selected 16 rice germplasms indicated that genotype Chinigura contained Pish, Pi9 and Pita genes; on the other hand, both BRRI dhan50 and Bawaibhog contained Pish and Pita genes in their genetic background. Genotypes Jirakatari, BR5, and Gopalbhog possessed Pish gene, while Uknimodhu, Deshikatari, Radhunipagol, Kalijira (3), Chinikanai each contained the Pita gene only. There are some materials that did not contain any target gene(s) in their genetic background, but proved resistant in pathogenicity tests. This information provided valuable genetic information for breeders to develop durable blast-resistant fragrant or aromatic rice varieties in Bangladesh. PMID:24841958

    Tuber yield, starch content, starch yield and chip color are complex traits that are important for industrial uses and food processing of potato. Chip color depends on the quantity of reducing sugars glucose and fructose in the tubers, which are generated by starch degradation. Reducing sugars accumulate when tubers are stored at low temperatures. Early and efficient selection of cultivars with superior yield, starch yield and chip color is hampered by the fact that reliable phenotypic selection requires multiple year and location trials. Application of DNA-based markers early in the breeding cycle, which are diagnostic for superior alleles of genes that control natural variation of tuber quality, will reduce the number of clones to be evaluated in field trials. Association mapping using genes functional in carbohydrate metabolism as markers has discovered alleles of invertases and starch phosphorylases that are associated with tuber quality traits. Here, we report on new DNA variants at loci encoding ADP-glucose pyrophosphorylase and the invertase Pain-1, which are associated with positive or negative effect with chip color, tuber starch content and starch yield. Marker-assisted selection (MAS) and marker validation were performed in tetraploid breeding populations, using various combinations of 11 allele-specific markers associated with tuber quality traits. To facilitate MAS, user-friendly PCR assays were developed for specific candidate gene alleles. In a multi-parental population of advanced breeding clones, genotypes were selected for having different combinations of five positive and the corresponding negative marker alleles. Genotypes combining five positive marker alleles performed on average better than genotypes with four negative alleles and one positive allele. When tested individually, seven of eight markers showed an effect on at least one quality trait. The direction of effect was as expected. Combinations of two to three marker alleles were

    Pre-selection for fruit skin color at the seedling stage would be highly advantageous, with marker-assisted selection offering a potential method for apple pre-selection. A and MdMYB1 alleles are allele-specific DNA markers that are potentially associated with apple skin color, and co-segregate with the Rf and Rni loci, respectively. Here, we assessed the potential application of these 2 alleles for marker-assisted breeding across 30 diverse cultivars and 2 apple seedling progenies. The red skin color phenotype was usually associated with the MdMYB1-1 allele and A(1) allele, respectively, while the 2 molecular markers provided approximately 91% predictability in the 'Fuji' x 'Cripps Pink' and 'Fuji' x 'Gala' progenies. The results obtained from the 30 cultivars and 2 progenies were consistent for the 2 molecular markers. Hence, the results supported that Rf and Rni could be located in a gene cluster, or even correspond to alleles of the same gene. Our results are consistent with the hypothesis that red/yellow dimorphism is controlled by a monogenic system, with the presence of the red anthocyanin pigmentation being dominant. In addition, our results supported that the practical utilization of the 2 function markers to efficiently and accurately select red-skinned apple cultivars in apple scion breeding programs.

    Consolidates relevant molecular and phenotypic information on cassava to demonstrate relevance of heterosis, and alternatives to exploit it by integrating different tools. Ideas are useful to other asexually reproduced crops. Asexually propagated crops offer the advantage that all genetic effects can be exploited in farmers' production fields. However, non-additive effects complicate selection because, while influencing the performance of the materials under evaluation, they cannot be transmitted efficiently to the following cycle of selection. Cassava can be used as a model crop for asexually propagated crops because of its diploid nature and the absence of (known) incompatibility effects. New technologies such as genomic selection (GS), use of inbred progenitors based on doubled haploids and induction of flowering can be employed for accelerating genetic gains in cassava. Available information suggests that heterosis, non-additive genetic effects and within-family variation are relatively large for complex traits such as fresh root yield, moderate for dry matter or starch content in the roots, and low for defensive traits (pest and disease resistance) and plant architecture. The present article considers the potential impact of different technologies for maximizing gains for key traits in cassava, and highlights the advantages of integrating them. Exploiting heterosis would be optimized through the implementation of reciprocal recurrent selection. The advantages of using inbred progenitors would allow shifting the current cassava phenotypic recurrent selection method into line improvement, which in turn would allow designing outstanding hybrids rather than finding them by trial and error.

    Carica papaya (papaya) is an economically important tropical fruit. Molecular marker-assisted selection is an inexpensive and reliable tool that has been widely used to improve fruit quality traits and resistance against diseases. In the present study we report the development and validation of an atlas of papaya simple sequence repeat (SSR) markers. We integrated gene predictions and functional annotations to provide a gene-centered perspective for marker-assisted selection studies. Our atlas comprises 160,318 SSRs, from which 21,231 were located in genic regions (i.e. inside exons, exon-intron junctions or introns). A total of 116,453 (72.6%) of all identified repeats were successfully mapped to one of the nine papaya linkage groups. Primer pairs were designed for markers from 9,594 genes (34.5% of the papaya gene complement). Using papaya-tomato orthology assessments, we assembled a list of 300 genes (comprising 785 SSRs) potentially involved in fruit ripening. We validated our atlas by screening 73 SSR markers (including 25 fruit ripening genes), achieving 100% amplification rate and uncovering 26% polymorphism rate between the parental genotypes (Sekati and JS12). The SSR atlas presented here is the first comprehensive gene-centered collection of annotated and genome positioned papaya SSRs. These features combined with thousands of high-quality primer pairs make the atlas an important resource for the papaya research community. PMID:25393538

    Polymerase chain reaction (PCR) provides a foundation for simple sequence repeat molecular marker-assisted selection (SSR MAS) in soybean. This PCR system and its various conditions have been optimized by many researchers. However, current research on the optimization of the PCR system focuses on double-primer PCR products. We compared single- and double-SSR primer PCR products from 50 soybean samples and found that the use of single-PCR primers in the reaction system can lead to amplified fragments of portions of the SSR primers in the PCR process, resulting in both false-positives and fragment impurity of double-primer PCR amplification, inconvenient for subsequent analysis. We used "single-primer PCR correction" to eliminate interference caused by single-primer nonspecific PCR amplification and improve PCR quality. Using this method, the precision and success rates of SSR MAS in soybean can be increased.

    Marker-assisted selection (MAS) is often employed in crop breeding programs to accelerate and enhance cultivar development, via selection during the juvenile phase and parental selection prior to crossing. Next-generation sequencing and its derivative technologies have been used for genome-wide molecular marker discovery. To bridge the gap between marker development and MAS implementation, this study developed a novel practical strategy with a semi-automated pipeline that incorporates trait-associated single nucleotide polymorphism marker discovery, low-cost genotyping through amplicon sequencing (AmpSeq) and decision making. The results document the development of a MAS package derived from genotyping-by-sequencing using three traits (flower sex, disease resistance and acylated anthocyanins) in grapevine breeding. The vast majority of sequence reads (⩾99%) were from the targeted regions. Across 380 individuals and up to 31 amplicons sequenced in each lane of MiSeq data, most amplicons (83 to 87%) had <10% missing data, and read depth had a median of 220-244×. Several strengths of the AmpSeq platform that make this approach of broad interest in diverse crop species include accuracy, flexibility, speed, high-throughput, low-cost and easily automated analysis.

    Blast is the most common biotic stress leading to the reduction of rice yield in many rice-growing areas of the world, including Malaysia. Improvement of blast resistance of rice varieties cultivated in blast endemic areas is one of the most important objectives of rice breeding programs. In this study, the marker-assisted backcrossing strategy was applied to improve the blast resistance of the most popular Malaysian rice variety MR219 by introgressing blast resistance genes from the Pongsu Seribu 2 variety. Two blast resistance genes, Pi-b and Pi-kh, were pyramided into MR219. Foreground selection coupled with stringent phenotypic selection identified 15 plants homozygous for the Pi-b and Pi-kh genes, and background selection revealed more than 95% genome recovery of MR219 in advanced blast resistant lines. Phenotypic screening against blast disease indicated that advanced homozygous blast resistant lines were strongly resistant against pathotype P7.2 in the blast disease endemic areas. The morphological, yield, grain quality, and yield-contributing characteristics were significantly similar to those of MR219. The newly developed blast resistant improved lines will retain the high adoptability of MR219 by farmers. The present results will also play an important role in sustaining the rice production of Malaysia. PMID:26734013

    Advantages of breeding schemes using genetic marker information and/or multiple ovulation and embryo transfer (MOET) technology over the traditional approach were extensively evaluated through simulation. Milk yield was the trait of interest and QTL was the genetic marker utilized. Eight dairy cattle breeding scenarios were considered, i.e., traditional progeny testing breeding scheme (denoted as STANPT), GASPT scheme including a pre-selection of young bulls entering progeny testing based on their own QTL information, MOETPT scheme using MOET technology to generate young bulls and a selection of young bulls limited within the full-sib family, GAMOPT scheme adopting both QTL pre-selection and MOET technology, COMBPT scheme using a mixed linear model which considered QTL genotype instead of the BLUP model in GAMOPT, and three non-progeny testing schemes, i.e. the MOET, GAMO and COMB schemes, corresponding to MOETPT, GAMOPT and COMBPT with progeny testing being part of the system. Animals were selected based on their breeding value which was estimated under an animal model framework. Sequential selection over 17 years was performed in the simulations and 30 replicates were designed for each scenario. The influences of using QTL information and MOET technology on favorable QTL allele frequency, true breeding values, polygenetic breeding values and the accumulated genetic superiority were extensively evaluated, for five different populations including active sires, lactating cows, bull dams, bull sires, and young bulls. The results showed that the combined schemes significantly outperformed other approaches wherein accumulated true breeding value progressed. The difference between schemes exclusively using QTL information or MOET technology was not significant. The STANPT scheme was the least efficient among the 8 schemes. The schemes using MOET technology had a higher polygenetic response than others in the 17th year. The increases of frequency of the favorable QTL

    Rust is a major pathogen of the peanut crop. Development and adoption of rust-resistant cultivars is the most cost efficient and effective way to control the spread of the disease and reduce yield losses. Some cultivated peanut germplasm accessions have a degree of resistance, but the secondary gene pool is a source of much stronger resistance alleles. Wild species, however, have undesirable agronomic traits that are a disincentive to their use in breeding. The identification of genomic regions that harbor disease resistance in wild species is the first step in the implementation of marker-assisted selection that can speed the introgression of wild disease resistances and the elimination of linkage drag. In this work, we identify genome regions that control different components of rust resistance in a recombinant inbred line population developed from a cross between two Arachis species, the susceptible most probable B genome ancestor of cultivated peanut, Arachis ipaënsis, and an accession of its closest relative, Arachis magna, which is resistant to rust. Quantitative trait loci for several components of resistance were placed in the same position on linkage group B08. Single-nucleotide polymorphism Kompetitive allele-specific polymerase chain reaction markers for rust resistance region were designed and validated for marker function in both diploid and tetraploid contexts.

    Developing fragrant rice through marker-assisted/aided selection (MAS) is an economical and profitable approach worldwide for the enrichment of an elite genetic background with a pleasant aroma. The PCR-based DNA markers that distinguish the alleles of major fragrance genes in rice have been synthesised to develop rice scent biofortification through MAS. Thus, the present study examined the aroma biofortification potential of these co-dominant markers in a germplasm panel of 189 F2 progeny developed from crosses between a non-aromatic variety (MR84) and a highly aromatic but low-yielding variety (MRQ74) to determine the most influential diagnostic markers for fragrance biofortification. The SSRs and functional DNA markers RM5633 (on chromosome 4), RM515, RM223, L06, NKSbad2, FMbadh2-E7, BADEX7-5, Aro7 and SCU015RM (on chromosome 8) were highly associated with the 2AP (2-acetyl-1-pyrroline) content across the population. The alleles traced via these markers were also in high linkage disequilibrium (R(2) > 0.70) and explained approximately 12.1, 27.05, 27.05, 27.05, 25.42, 25.42, 20.53, 20.43 and 20.18% of the total phenotypic variation observed for these biomarkers, respectively. F2 plants harbouring the favourable alleles of these effective markers produced higher levels of fragrance. Hence, these rice plants can be used as donor parents to increase the development of fragrance-biofortified tropical rice varieties adapted to growing conditions and consumer preferences, thus contributing to the global rice market.

  12. Large-scale analysis of differential gene expression in coffee genotypes resistant and susceptible to leaf miner–toward the identification of candidate genes for marker assisted-selection

    2014-01-01

    Background A successful development of herbivorous insects into plant tissues depends on coordination of metabolic processes. Plants have evolved complex mechanisms to recognize such attacks, and to trigger a defense response. To understand the transcriptional basis of this response, we compare gene expression profiles of two coffee genotypes, susceptible and resistant to leaf miner (Leucoptera coffella). A total of 22000 EST sequences from the Coffee Genome Database were selected for a microarray analysis. Fluorescence probes were synthesized using mRNA from the infested and non-infested coffee plants. Array hybridization, scanning and data normalization were performed using Nimble Scan® e ArrayStar® platforms. Genes with foldchange values +/-2 were considered differentially expressed. A validation of 18 differentially expressed genes was performed in infected plants using qRT-PCR approach. Results The microarray analysis indicated that resistant plants differ in gene expression profile. We identified relevant transcriptional changes in defense strategies before insect attack. Expression changes (>2.00-fold) were found in resistant plants for 2137 genes (1266 up-regulated and 873 down-regulated). Up-regulated genes include those responsible for defense mechanisms, hypersensitive response and genes involved with cellular function and maintenance. Also, our analyses indicated that differential expression profiles between resistant and susceptible genotypes are observed in the absence of leaf-miner, indicating that defense is already build up in resistant plants, as a priming mechanism. Validation of selected genes pointed to four selected genes as suitable candidates for markers in assisted-selection of novel cultivars. Conclusions Our results show evidences that coffee defense responses against leaf-miner attack are balanced with other cellular functions. Also analyses suggest a major metabolic reconfiguration that highlights the complexity of this response. PMID

    Current advances in plant genotyping lead to major progress in the knowledge of genetic architecture of traits of interest. It is increasingly important to develop decision support tools to help breeders and geneticists to conduct marker-assisted selection methods to assemble favorable alleles that are discovered. Algorithms have been implemented, within an interactive graphical interface, to 1) trace parental alleles throughout generations, 2) propose strategies to select the best plants based on estimated molecular scores, and 3) efficiently intermate them depending on the expected value of their progenies. With the possibility to consider a multi-allelic context, OptiMAS opens new prospects to assemble favorable alleles issued from diverse parents and further accelerate genetic gain. PMID:23576670

    Development of kunitz trypsin inhibitor (KTI)-free soybean is crucial for soy-food industry as the heat inactivation employed to inactivate the anti-nutritional factor in regular soybean incurs extra cost and affects protein solubility. In the presented work, a null allele of KTI from PI542044 was introgressed into cultivar ‘JS97-52’ (recurrent parent) through marker assisted backcrossing. Foreground selection in BC1F2, BC2F2 and BC3F2 was carried out using the null allele-specific marker in tandem with SSR marker Satt228, tightly linked with a trypsin inhibitor Ti locus. Background selection in null allele-carrying plants through 106 polymorphic SSR markers across the genome led to the identification of 9 KTI-free lines exhibiting 98.6% average recurrent parent genome content (RPGC) after three backcrosses, which otherwise had required 5–6 backcrosses through conventional method. Introgressed lines (ILs) were free from KTI and yielded at par with recurrent parent. Reduction of 68.8–83.5% in trypsin inhibitor content (TIC) in ILs compared to the recurrent parent (‘JS97-52’) was attributed to the elimination of KTI. PMID:26719748

    The cytoplasmic male sterile line system comprising CRMS 32A and its maintainer line CRMS 32B is a popular choice for the development of new hybrids in India as CRMS 32A, having Kalinga 1 cytoplasm (other than WA), is a viable alternative to WA cytoplasm. However, both lines are susceptible to bacterial blight (BB), a major disease on rice. As enhancement of host plant resistance is the most effective and economical strategy to control this disease, four resistance genes (Xa4, xa5, xa13, and Xa21) were transferred from a BB pyramid line of IR64, into the A and B lines using a marker-assisted backcrossing (MAB) breeding strategy. During the transfer of genes into CRMS 32B, foreground selection was applied using markers associated with the genes, and plants having resistance alleles of the donor, are selected. Selection for morphological and quality traits was practiced to select plants similar to the recurrent parent. The four gene and three gene pyramid lines exhibited high levels of resistance against the BB pathogen when challenged with eight virulent isolates. Using genome wide based SSR markers for background selection, pyramids having >95% of the recurrent parent genome were identified. With CRMS 32B gene pyramid as donor, the four resistance genes were transferred into the A line through repeated backcrosses and the A line pyramids also exhibited high level of resistance against BB. Through a combination of selection at phenotypic and molecular levels, four BB resistance genes were successfully introduced into two parental lines (CRMS 32 B and A) of Rajalaxmi, an elite popular hybrid. The pyramided B lines did exhibit high levels of resistance against BB. Selection for morphological and quality traits and background selection hastened the recovery of the recurrent parent genome in the recombinants.

    Backcross breeding is the most commonly used method for incorporating a blast resistance gene into a rice cultivar. Linkage between the resistance gene and undesirable units can persist for many generations of backcrossing. Marker-assisted backcrossing (MABC) along with marker-assisted selection (MAS) contributes immensely to overcome the main limitation of the conventional breeding and accelerates recurrent parent genome (RPG) recovery. The MABC approach was employed to incorporate (a) blast resistance gene(s) from the donor parent Pongsu Seribu 1, the blast-resistant local variety in Malaysia, into the genetic background of MR219, a popular high-yielding rice variety that is blast susceptible, to develop a blast-resistant MR219 improved variety. In this perspective, the recurrent parent genome recovery was analyzed in early generations of backcrossing using simple sequence repeat (SSR) markers. Out of 375 SSR markers, 70 markers were found polymorphic between the parents, and these markers were used to evaluate the plants in subsequent generations. Background analysis revealed that the extent of RPG recovery ranged from 75.40% to 91.3% and from 80.40% to 96.70% in BC1F1 and BC2F1 generations, respectively. In this study, the recurrent parent genome content in the selected BC2F2 lines ranged from 92.7% to 97.7%. The average proportion of the recurrent parent in the selected improved line was 95.98%. MAS allowed identification of the plants that are more similar to the recurrent parent for the loci evaluated in backcross generations. The application of MAS with the MABC breeding program accelerated the recovery of the RP genome, reducing the number of generations and the time for incorporating resistance against rice blast.

    We investigated the effects of previously identified quantitative trait loci (QTL) in an experimental backcross (BC) between Chinese Meishan pigs and commercial Duroc pigs. We performed marker-assisted introgression of two QTL for intramuscular fat (IMF) content (IMF population) and three QTL for reproductive traits (reproduction population) from a donor Meishan pig into a recipient Duroc pig. At the fourth BC generation of the IMF population and third BC generation of the reproduction population, carrier animals were selected for the production of animals homozygous for the QTL. Our previous studies have shown that the presence of a Meishan allele on the IMF QTL is associated with low IMF values, and the Meishan allele on the reproductive QTL is associated with large litters. In this study, the presence of a Duroc allele at the IMF QTL on SSC9 resulted in a 0.27% increase in IMF (additive effect = 0.27 ± 0.08), whereas the presence of a Meishan allele at the IMF QTL on SSC7 resulted in a 0.34% increase in IMF (additive effect = -0.34 ± 0.09). The presence of the Meishan allele at the IMF QTL on SSC7 thus had the opposite effect to our previous studies, that is, increased IMF. In the reproduction population, we observed no differences between the genotypes of the three QTL in regard to number of corpora lutea or litter size. Marker-assisted introgression at these QTL is thus unlikely to result in an associated increase in litter size. These results show that it is possible to introgress alleles from other breeds into a selection population using molecular markers; any unexpected results might be associated with the genetic background.

    Severe yield loss due to various biotic stresses like bacterial blight (BB), gall midge (insect) and Blast (disease) and abiotic stresses like submergence and salinity are a serious constraint to the rice productivity throughout the world. The most effective and reliable method of management of the stresses is the enhancement of host resistance, through an economical and environmentally friendly approach. Through the application of marker assisted selection (MAS) technique, the present study reports a successful pyramidization of genes/QTLs to confer resistance/tolerance to blast (Pi2, Pi9), gall Midge (Gm1, Gm4), submergence (Sub1), and salinity (Saltol) in a released rice variety CRMAS2621-7-1 as Improved Lalat which had already incorporated with three BB resistance genes xa5, xa13, and Xa21 to supplement the Xa4 gene present in Improved Lalat. The molecular analysis revealed clear polymorphism between the donor and recipient parents for all the markers that are tagged to the target traits. The conventional backcross breeding approach was followed till BC3F1 generation and starting from BC1F1 onwards, marker assisted selection was employed at each step to monitor the transfer of the target alleles with molecular markers. The different BC3F1s having the target genes/QTLs were inter crossed to generate hybrids with all 10 stress resistance/tolerance genes/QTLs into a single plant/line. Homozygous plants for resistance/tolerance genes in different combinations were recovered. The BC3F3 lines were characterized for their agronomic and quality traits and promising progeny lines were selected. The SSR based background selection was done. Most of the gene pyramid lines showed a high degree of similarity to the recurrent parent for both morphological, grain quality traits and in SSR based background selection. Out of all the gene pyramids tested, two lines had all the 10 resistance/tolerance genes and showed adequate levels of resistance/tolerance against the five target

    Rapid and accurate genome-wide marker detection is essential to the marker-assisted breeding and functional genomics studies. In this work, we developed an integrated software, AgroMarker Finder (AMF: http://erp.novelbio.com/AMF), for providing graphical user interface (GUI) to facilitate the recently developed restriction-site associated DNA (RAD) sequencing data analysis in rice. By application of AMF, a total of 90,743 high-quality markers (82,878 SNPs and 7,865 InDels) were detected between rice varieties JP69 and Jiaoyuan5A. The density of the identified markers is 0.2 per Kb for SNP markers, and 0.02 per Kb for InDel markers. Sequencing validation revealed that the accuracy of genome-wide marker detection by AMF is 93%. In addition, a validated subset of 82 SNPs and 31 InDels were found to be closely linked to 117 important agronomic trait genes, providing a basis for subsequent marker-assisted selection (MAS) and variety identification. Furthermore, we selected 12 markers from 31 validated InDel markers to identify seed authenticity of variety Jiaoyuanyou69, and we also identified 10 markers closely linked to the fragrant gene BADH2 to minimize linkage drag for Wuxiang075 (BADH2 donor)/Jiachang1 recombinants selection. Therefore, this software provides an efficient approach for marker identification from RAD-seq data, and it would be a valuable tool for plant MAS and variety protection. PMID:26799713

    Development of vitamin A-rich cereals can help in alleviating the widespread problem of vitamin A deficiency. We report here significant enhancement of kernel β-carotene in elite maize genotypes through accelerated marker-assisted backcross breeding. A favourable allele (543 bp) of the β-carotene hydroxylase (crtRB1) gene was introgressed in the seven elite inbred parents, which were low (1.4 µg/g) in kernel β-carotene, by using a crtRB1-specific DNA marker for foreground selection. About 90% of the recurrent parent genome was recovered in the selected progenies within two backcross generations. Concentration of β-carotene among the crtRB1-introgressed inbreds varied from 8.6 to 17.5 µg/g - a maximum increase up to 12.6-fold over recurrent parent. The reconstituted hybrids developed from improved parental inbreds also showed enhanced kernel β-carotene as high as 21.7 µg/g, compared to 2.6 µg/g in the original hybrid. The reconstituted hybrids evaluated at two locations possessed similar grain yield to that of original hybrids. These β-carotene enriched high yielding hybrids can be effectively utilized in the maize biofortification programs across the globe. PMID:25486271

    The eating and cooking qualities of rice are heavily emphasized in breeding programs because they determine market values and they are the appealing attributes sought by consumers. Conventional breeding has developed traditional varieties with improved eating and cooking qualities. Recently, intensive genetic studies have pinpointed the genes that control eating and cooking quality traits. Advances in genetic studies have developed molecular techniques, thereby allowing marker-assisted breeding (MAB) for improved eating and cooking qualities in rice. MAB has gained the attention of rice breeders for the advantages it can offer that conventional breeding cannot. There have been successful cases of using MAB to improve the eating and cooking qualities in rice over the years. Nevertheless, MAB should be applied cautiously given the intensive effort needed for genotyping. Perspectives from conventional breeding to marker-assisted breeding will be discussed in this review for the advancement of the eating and cooking qualities of fragrance, amylose content (AC), gel consistency (GC) and gelatinization temperature (GT) in rice. These four parameters are associated with eating and cooking qualities in rice. The genetic basis of these four parameters is also included in this review. MAB is another approach to rice variety improvement and development in addition to being an alternative to genetic engineering. The MAB approach shortens the varietal development time, and is therefore able to deliver improved rice varieties to farmers within a shorter period of time.

    The present study was undertaken to detect and map the quantitative trait loci (QTL) related to soybean oil content. We used 244 progenies derived from a bi-parental cross of the Lineage 69 (from Universidade Estadual Paulista "Júlio de Mesquita Filho"/Faculdade de Ciências Agrárias e Veterinárias - Breeding Program) and Tucunaré cultivar. A total of 358 simple sequence repeat (SSR; microsatellite) markers were used to investigate the polymorphism between the parental lines, and for the polymorphic lines all the F2 individuals were tested. Evaluation of the oil content and phenotype was performed with the aid of a Tango equipment by near infra-red reflectance spectroscopy, using single F2 seeds and F2:3 progenies, in triplicate. The data were analyzed by QTL Cartographer program for 56 SSR polymorphic markers. Two oil-content related QTLs were detected on K and H linkage groups. The total phenotypic variation explained by QTLs ranged from 7.8 to 46.75% for oil content. New QTLs were identified for the oil content in addition to those previously identified in other studies. The results reported in this study show that regions different from those already known could be involved in the genetic control of soybean oil content.

    The present study was undertaken to detect and map the quantitative trait loci (QTL) related to soybean oil content. We used 244 progenies derived from a bi-parental cross of the Lineage 69 (from Universidade Estadual Paulista "Júlio de Mesquita Filho"/Faculdade de Ciências Agrárias e Veterinárias - Breeding Program) and Tucunaré cultivar. A total of 358 simple sequence repeat (SSR; microsatellite) markers were used to investigate the polymorphism between the parental lines, and for the polymorphic lines all the F2 individuals were tested. Evaluation of the oil content and phenotype was performed with the aid of a Tango equipment by near infra-red reflectance spectroscopy, using single F2 seeds and F2:3 progenies, in triplicate. The data were analyzed by QTL Cartographer program for 56 SSR polymorphic markers. Two oil-content related QTLs were detected on K and H linkage groups. The total phenotypic variation explained by QTLs ranged from 7.8 to 46.75% for oil content. New QTLs were identified for the oil content in addition to those previously identified in other studies. The results reported in this study show that regions different from those already known could be involved in the genetic control of soybean oil content. PMID:27050959

    2015-01-01

    Objective. To reflect on selection policies and procedures for programs at pharmacy schools that are members of an international alliance of universities (Universitas 21). Methods. A questionnaire on selection policies and procedures was distributed to admissions directors at participating schools. Results. Completed questionnaires were received from 7 schools in 6 countries. Although marked differences were noted in the programs in different countries, there were commonalities in the selection processes. There was an emphasis on previous academic performance, especially in science subjects. With one exception, all schools had some form of interview, with several having moved to multiple mini-interviews in recent years. Conclusion. The majority of pharmacy schools in this survey relied on traditional selection processes. While there was increasing use of multiple mini-interviews, the authors suggest that additional new approaches may be required in light of the changing nature of the profession. PMID:26689381

  11. What Israeli policy can teach us about elective sex selection.

    PubMed

    Leiter, Gila

    2014-01-01

    PIGD for gender selection for non medical reasons has been a subject of ethical, legal, and moral debate in many Western countries. This article discusses the background of elective sex selection, and highlights the impact of new technological developments on this dynamic discussion. The article published by Pessach et al., in this Journal, is an excellent study of Israeli health policy on non medically indicated preimplantation genetic screening for sex selection. In Israel, elective sex selection is prohibited, but exceptions can be made by application, for family balancing, and emotional and religious reasons. This review of a health policy over seven years is concordant with evolving views in many Western countries. The classic medical model for allowing sex selection for serious medical disorders may be too restrictive. There are different reasons that may be assessed in light of ethical criteria including a wider delineation of medical reasons, which may include emotional and psychological well being of the family, indirect medical reasons, as well as risk reduction for the following generations. The Israeli model may be a useful approach with wide application to reproductive health policies in many countries.

    The present study firstly reports the cytological and molecular marker assisted differentiation of isomorphic population of Gracilaria corticata (J. Agardh) with inter and intra-phasic genetic diversity analysis using ISSR markers. The genetic diversity of inbreeding population of G. corticata as determined in terms of percentage of polymorphic loci (PPL), average heterozygosity (He) and Shannon's Weaver index (I) were 59.80, 0.59 and 1.21, respectively. The inter-phasic pair-wise average polymorphism were found to be 31.6% between male and female, 24.0% in male and tetrasporophyte and 25.3% in female and tetrasporophyte. The intra-phasic average polymorphisms were calculated as a maximum of 5.5% between females, 4.2% between males and the lowest 2.4% between tetrasporophytes. The primer 10 generated a marker of 800 bp specific to male and 650 bp to female gametophyte, while the primer 17 generated a marker of 2,500 bp specific to tetrasporophyte. Both the UPGMA based dendrogram and PCA analysis clustered all the three life phases differentially as distinct identity. Cytological analysis by chromosome count revealed 24 chromosomes in both haploid male and female gametophytes (N) and 48 for diploid (2 N) tetrasporophyte further confirming their genetic distinctness. The life phase specific markers reported in this study could be of help in breeding programmes where differentiation of life phases at the early developmental stages is crucial.

  13. Enhancement of Seedling Emergence in Sweet Corn by Marker-Assisted Backcrossing of Beneficial QTL.

    2002-01-01

    Seedling emergence is an important trait that can limit commercialization of sweet corn hybrids. This study was designed to test what effect beneficial QTL alleles that enhance seedling emergence exert when introgressed, using marker-assisted backcrossing, into sweet corn commercial germplasm. Three RFLP marker alleles linked to QTL that enhanced seedling emergence were identified in an F(2:3) sweet corn mapping population. A recombinant inbred line (RIL, F(8)) derived from this population was used as a donor parent to backcross the marker-QTL alleles into three elite commercial sweet corn inbreds. Plants in the three segregating BC(2) populations were crossed to the non-recurrent commercial inbreds to produce three BC(2)F(1) populations with families either segregating or lacking the marker donor allele(s). These three populations were evaluated for seedling emergence under field conditions in two successive years. Across the three populations, BC(2)F(1) families segregating for the donor QTL allele linked to the marker umc139 (on chromosome 2), bnl9.08 (on chromosome 8), or php200689 (on chromosome 1) displayed 40.8, 30.2, and 28.2% increases in seedling emergence, respectively, over the unmodified F(1)s. The introgressed QTL alleles were observed to enhance seedling emergence in the BC(2)F(1) generation as was observed in the original F(2:3) mapping population. Marker-QTL associated effects were reproducible across generations and populations indicating that QTL identified in one population can exert similar effects in different genetic backgrounds. Results suggest that using DNA marker technology can help to identify and introgress beneficial QTL alleles, shortening the time and resources required to develop improved germplasm. PMID:11756259

    AIM To evaluate the efficacy of toric intraocular lens markers-assisted implantation of the scleral-fixated intraocular lens (SFIOL). METHODS From October 2010 to December 2013, all patients who had undergone secondary SFIOL implantation were assigned to group 1 and 2, in group 1 SFIOL was performed with the assist of radial keratotomy (RK)-marker, and in group 2 SFIOL was performed with the assisted of toric intraocular lens markers (T-and axis markers). Patients' demographic data and information on baseline preoperative visual acuity, indication for surgery and latest postoperative visual acuity were collected and analyzed. The haptic and optic positions were determined by ultrasound biomicroscopy. The optic tilt angle and decentration distance were measured. RESULTS The study evaluated 43 eyes of 43 patients ranging in age from 3 to 66y. Group 1 comprised 24 eyes (24 patients) and group 2, 19 eyes (19 patients). Uncorrected reoperative acuity was improved on all the eyes postoperatively. The improved postoperative acuity was significantly more in group 2 than that in group 1 (1.11±0.38 vs 0.82±0.45 logMAR; F=4.85, P=0.03). Ultrasonic biomicrograph examination showed that the rate of haptic asymmetry was significantly higher in group 1 (42%, 10/24) than that in group 2 (11%; 2/19) (Chi square=3.68, P=0.04). The mean tilted degree in group 1 was significantly higher than that in group 2 (P=0.04). Mean decentration distance in group 1 was greater than that in group 2 (P=0.03). CONCLUSION During SFIOL the toric markers help the surgeon identify the placement of fixation more precisely than that with the use of RK marker. PMID:27672593

    Objective: The purpose of this research was to investigate the hazards of lightning for participants in outdoor athletics and to determine the existence of, and assess the nature of, lightning safety policy at the collegiate level. Design and Setting: We used data from the National Severe Storms Laboratory in Norman, Oklahoma, and from a survey of Division I institutions. Subjects: The 48 National Collegiate Athletic Association Division I (football) universities in Florida, Michigan, Pennsylvania, North Carolina, and New York. Measurements: Athletic trainers at all of the selected 48 Division I institutions responded to the telephone survey. Results: Florida, Michigan, Pennsylvania, North Carolina, and New York led the country in lightning deaths and injuries from 1959-1994. Only 8% (n = 4) of the institutions surveyed in these states have a written policy regarding lightning safety. Conclusions: This study demonstrated the lack of lightning safety policy in the surveyed universities and the need for a systematic plan of action to make fields safer for all who are involved in outdoor sport activities.

    NAPAP is examining a number of potential ways to reduce the precursors (sulfur dioxide and nitrogen oxides) to acid deposition. However, the policies to reduce acid deposition will have other physical, biological and economic effects unrelated to acid deposition. For example, control policies that reduce sulfur dioxide emissions may also increase visibility. The effects of an acid deposition policy that are unrelated to acid deposition are referred to as ''ancillary'' effects. This reserch identifies and characterizes the principle physical and economic ancillary effects associated with acid deposition control and mitigation policies. In this study the ancillary benefits associated with four specific acid deposition policy options were investigated. The four policy options investigated are: (1) flue gas desulfurization, (2) coal blending or switching, (3) reductions in automobile emissions of NO/sub x/, and (4) lake liming. Potential ancillary benefits of each option were identified and characterized. Particular attention was paid to the literature on economic valuation of potential ancillary effects.

    Bacterial blight (BB) of rice caused by Xanthomonas oryzae pv. oryzae is a major disease of rice in many rice growing countries. Pyramided lines carrying two BB resistance gene combinations (Xa21+xa13 and Xa21+xa5) were developed in a lowland cultivar Jalmagna background through backcross breeding by integrating molecular markers. In each backcross generation, markers closely linked to the disease resistance genes were used to select plants possessing the target genes. Background selection was continued in those plants carrying resistant genes until BC(3) generation. Plants having the maximum contribution from the recurrent parent genome were selected in each generation and hybridized with the recipient parent. The BB-pyramided line having the maximum recipient parent genome recovery of 95% was selected among BC3F1 plants and selfed to isolate homozygous BC(3)F(2) plants with different combinations of BB resistance genes. Twenty pyramided lines with two resistance gene combinations exhibited high levels of tolerance against the BB pathogen. In order to confirm the resistance, the pyramided lines were inoculated with different X. oryzae pv. oryzae strains of Odisha for bioassay. The genotypes with combination of two BB resistance genes conferred high levels of resistance to the predominant X. oryzae pv. oryzae isolates prevalent in the region. The pyramided lines showed similarity with the recipient parent with respect to major agro-morphologic traits.

  6. Persimmon breeding in Japan for pollination-constant non-astringent (PCNA) type with marker-assisted selection.

    PubMed

    Sato, Akihiko; Yamada, Masahiko

    2016-01-01

    Oriental persimmon (Diospyros kaki) originated in Eastern Asia, and many indigenous cultivars have been developed in China, Japan, and Korea. These cultivars are classified into four groups based on their natural astringency loss on the tree and seed formation: pollination-constant non-astringent (PCNA), pollination-variant non-astringent (PVNA), pollination-constant astringent (PCA), and pollination-variant astringent (PVA). PCNA is the most desirable type because the fruit can be eaten without any postharvest treatment; therefore, one of the goals of our persimmon breeding programs is to release superior PCNA cultivars. The PCNA genotype is recessive to the other three non-PCNA genotypes, and PCNA-type F1 offspring are obtained exclusively from crosses among PCNA genotypes. Moreover, the number of superior PCNA cross-parents have been limited. In the late 1980s, inbreeding depression became obvious, especially in terms of fruit size, tree vigor, and productivity. To mitigate the inbreeding, a backcross program using PCNA [(non-PCNA × PCNA) × PCNA] was started in 1990. This process, however, was inefficient because only 15% of the offspring were PCNA, and all offspring had to be grown to the fruiting stage. Therefore, molecular markers linked to the PCNA locus were developed for discriminating PCNA offspring. A molecular marker linked to Chinese PCNA has also been developed. PMID:27069391

    2014-09-01

    Rust resistance in the sunflower line P386 is controlled by Pu 6 , a gene which was reported to segregate independently from other rust resistant genes, such as R 4 . The objectives of this work were to map Pu 6 , to provide and validate molecular tools for its identification, and to determine the linkage relationship of Pu 6 and R 4 . Genetic mapping of Pu 6 with six markers covered 24.8 cM of genetic distance on the lower end of linkage Group 13 of the sunflower consensus map. The marker most closely linked to Pu 6 was ORS316 at 2.5 cM in the distal position. ORS316 presented five alleles when was assayed with a representative set of resistant and susceptible lines. Allelism test between Pu 6 and R 4 indicated that both genes are linked at a genetic distance of 6.25 cM. This is the first confirmation based on an allelism test that at least two members of the R adv /R 4 /R 11 / R 13a /R 13b /Pu 6 cluster of genes are at different loci. A fine elucidation of the architecture of this complex locus will allow designing and constructing completely new genomic regions combining genes from different resistant sources and the elimination of the linkage drag around each resistant gene.

  10. On marker-assisted prediction of genetic value: beyond the ridge.

    PubMed Central

    Gianola, Daniel; Perez-Enciso, Miguel; Toro, Miguel A

    2003-01-01

    Marked-assisted genetic improvement of agricultural species exploits statistical dependencies in the joint distribution of marker genotypes and quantitative traits. An issue is how molecular (e.g., dense marker maps) and phenotypic information (e.g., some measure of yield in plants) is to be used for predicting the genetic value of candidates for selection. Multiple regression, selection index techniques, best linear unbiased prediction, and ridge regression of phenotypes on marker genotypes have been suggested, as well as more elaborate methods. Here, phenotype-marker associations are modeled hierarchically via multilevel models including chromosomal effects, a spatial covariance of marked effects within chromosomes, background genetic variability, and family heterogeneity. Lorenz curves and Gini coefficients are suggested for assessing the inequality of the contribution of different marked effects to genetic variability. Classical and Bayesian methods are presented. The Bayesian approach includes a Markov chain Monte Carlo implementation. The generality and flexibility of the Bayesian method is illustrated when a Lorenz curve is to be inferred. PMID:12586721

    Mungbean Yellow Mosaic India Virus (MYMIV) belonging to the genus begomovirus causes the yellow mosaic disease in a number of economically important edible grain legumes including mungbean (Vigna radiata), urdbean (Vigna mungo) and soybean (Glycine max). The disease is severe, critical, open spread and inflicts heavy yield losses annually. The objective of this study is to develop molecular markers linked to MYMIV-resistance to facilitate genotyping of urdbean and mungbean germplasms for MYMIV-reaction. Resistance-linked molecular markers were successfully developed from consensus motifs of other resistance (R) gene or R gene homologue sequences. Applying linked marker-assisted genotyping, plant breeders can carry out repeated genotyping throughout the growing season in absence of any disease incidence. Two MYMIV-resistance marker loci, YR4 and CYR1, were identified and of these two CYR1 is completely linked with MYMIV-resistant germplasms and co-segregating with MYMIV-resistant F₂, F₃ progenies of urdbean. The present study demonstrated that these two markers could be efficiently employed together in a multiplex-PCR-reaction for genotyping both V. mungo and V. radiata germplasms from field grown plants and also directly from the seed stock. This method of genotyping would save time and labour during the introgression of MYMIV-resistance through molecular breeding, as methods of phenotyping against begomoviruses are tedious, labour and time intensive.

    In most decision-making involving natural resources, the achievements of a given policy (e.g., improved ecosystem or biodiversity) are rather difficult to measure in monetary units. To address this problem, the current paper develops an environmental cost-effectiveness analysis (ECEA) to include intangible benefits in intertemporal natural resource problems. This approach can assist managers in prioritizing management actions as least cost solutions to achieve quantitative policy targets. The ECEA framework is applied to a selective gear policy case in Danish mixed trawl fisheries in Kattegat and Skagerrak. The empirical analysis demonstrates how a policy with large negative net benefits might be justified if the intangible benefits are included.

    This research investigates selected South Dakota science educational outcomes as a function of selected educational reform policies. In the state of South Dakota, echoing divergent reform initiatives from "A Nation at Risk" to "No Child Left Behind," new guidelines and requirements have been instituted. Yet, very little effort has been made to assess the progress of these educational changes. In this study, selected educational outcomes-SAT8/9/10 scores-as a function of selected South Dakota educational reform policies were examined. School districts, ranked in the top and bottom five percent of socioeconomic status (SES) in the state, were selected for analysis. Comparison on student's science educational outcomes was also be made between the two major ethnic populations-Caucasians and Native Americans. All research questions were stated in the null form for hypothesis for statistical testing. Critical t was the statistic technique used to test the hypotheses. The findings revealed that the selected reform policies in South Dakota appeared to assist students from the higher socioeconomic backgrounds to perform better than pupils from the lower socioeconomic backgrounds. The academic performance for the ethnic and social class minorities remained unchanged within the study timeline for reform. Examined from the prism of Michael Apple's critical theory, the selected South Dakota reform policies have paid little attention to the issues of social equality. Continuing and collective efforts to promote equitable reform policies for enhancing the learning experience of all children in South Dakota seem necessary.

    Between now and 2030, every country will experience population ageing-a trend that is both pronounced and historically unprecedented. Over the past six decades, countries of the world had experienced only a slight increase in the share of people aged 60 years and older, from 8% to 10%. But in the next four decades, this group is expected to rise to 22% of the total population-a jump from 800 million to 2 billion people. Evidence suggests that cohorts entering older age now are healthier than previous ones. However, progress has been very uneven, as indicated by the wide gaps in population health (measured by life expectancy) between the worst (Sierra Leone) and best (Japan) performing countries, now standing at a difference of 36 years for life expectancy at birth and 15 years for life expectancy at age 60 years. Population ageing poses challenges for countries' economies, and the health of older populations is of concern. Older people have greater health and long-term care needs than younger people, leading to increased expenditure. They are also less likely to work if they are unhealthy, and could impose an economic burden on families and society. Like everyone else, older people need both physical and economic security, but the burden of providing these securities will be falling on a smaller portion of the population. Pension systems will be stressed and will need reassessment along with retirement policies. Health systems, which have not in the past been oriented toward the myriad health problems and long-term care needs of older people and have not sufficiently emphasised disease prevention, can respond in different ways to the new demographic reality and the associated changes in population health. Along with behavioural adaptations by individuals and businesses, the nature of such policy responses will establish whether population ageing will lead to major macroeconomic difficulties.

    BACKGROUND: Hospitals have responsibility for responding to legitimate demands for release of health information while protecting the confidentiality of the patient health records. There have always been challenges concerning medical records confidentiality and their disclosure and release type in medical record departments. This study investigated and compared laws and policies of disclosure of health information in Iran and selected countries and tried to identify the differences and the similarities between them. METHODS: This is a descriptive and comparative study. The scope of study included related laws and policies of disclosure of health information in selected countries such as United States, Australia, England, Malaysia and Iran. Data were gathered from systematic internet search, library resources and communication with health information professionals. Data analysis was done using comparative tables and qualitative method. RESULTS: Study results showed that legislative institutions of each country have ordained laws and policies concerning disclosure and release of health information and in turn hospitals developed policies and procedures based on these laws. In Iran, however, there are few laws and policies concerning disclosure of health information in the form of formal letters and bylaws. There are no specific written policies and procedures for disclosure of health information in the hospitals. CONCLUSIONS: It is necessary to develop legitimate and appropriate laws and policies in different levels for information utilization by hospitals, medical universities and others. Meanwhile in all of the selected countries there are ordained limitations for release of health information for protecting health information in regard to patient rights. PMID:21526073

    2016-03-01

    We report on an ongoing project to develop data-driven tools to help individuals make better choices about health insurance and to better understand the range of costs to which they are exposed under different health plans. We describe a simulation tool that we developed to evaluate the likely usage and costs for an individual and family under a wide range of health service usage outcomes, but that can be tailored to specific physicians and the needs of the user and to reflect the demographics and other special attributes of the family. The simulator can accommodate, for example, specific known physician visits or planned procedures, while also generating statistically reasonable "unexpected" events like ER visits or catastrophic diagnoses. On the other hand, if a user provides only a small amount of information (e.g., just information about the family members), the simulator makes a number of generic assumptions regarding physician usage, etc., based on the age, gender, and other features of the family. Data to parameterize all of these events is informed by a combination of the information provided by the user and a series of specialized databases that we have compiled based on publicly available government data and commercial data as well as our own analysis of this initially very coarse and rigid data. To demonstrate both the subtlety of choosing a healthcare plan and the degree to which the simulator can aid in such evaluations, we present sample results using real insurance plans and two example policy shoppers with different demographics and healthcare needs.

    2008-01-01

    Classical scrapie has proved to be a notoriously difficult disease to control due to a poor understanding of its natural history. The recognition of disease risk linkage to PrP genotype has offered the prospect of a disease control strategy, viz. genotyping and selective breeding, novel to veterinary medicine when first considered in the 1990s. The UK Spongiform Encephalopathy Advisory Committee recommended the exploitation of this approach in a voluntary, national programme to control classical scrapie and protect the public against food-borne exposure to bovine spongiform encephalopathy, should the national flock have been exposed via contaminated feed. The National Scrapie Plan for Great Britain was launched in 2001 and uptake has been widespread throughout the purebreeding sector of the sheep industry, with membership peaking at over 12 000 flocks in 2006. A total of 700 000 rams from 90 breeds have been genotyped. A comparison of ram lambs born in 2002 with those in 2006 shows evident changes in PrP genotype frequencies which are predicted to be associated with a reduction in disease risk. Various concerns have been raised regarding possible unintended consequences of widespread selection on PrP genotype, including impacts on other performance traits and possible effects on inbreeding and genetic diversity. To date, these concerns appear to be unfounded, as no consistent associations have been found with performance traits, nor are there likely to be any detectable impacts on inbreeding in mainstream breeds. Currently, semen banks have been implemented in Great Britain to store samples from animals of all common PrP genotypes, should these genotypes be required in the future. Various strategies to minimise future disease risks are discussed in the paper.

  14. Science-Policy Interactions in MPA Site Selection in the Dutch Part of the North Sea

    At the 7th conference of the parties to the Convention on Biological Diversity (CBD-COP7, Kuala Lumpur, 2004) it was agreed to establish a global network of marine and coastal protected areas by 2012. The defined objectives of this MPA-network are based on the ecosystem approach: to protect biodiversity and other ecological values, and to ensure sustainable use. The (inter)national policy guidelines state that the selection of MPAs should be based on scientific information and ecological criteria only. As a signatory to the Convention, the Netherlands is now faced with meeting this obligation, and the process of designating the first Marine Protected Areas (MPAs) in the Dutch part of the North Sea is currently in progress. We focus on the science-policy interactions that are part of this Dutch MPA selection process. By taking a closer look at the contemporary site selection process as well as its historical background, we show that ecological, socio-economic and political considerations cannot always be easily separated. Uncertainty is high and the ultimate selection and delimitation of candidate sites rather seems to be the result of a balancing act between ecological, socio-economic and political interests, in which scientific and policy guiding procedures blend with ad-hoc political decision making, and with expert judgment in cases where data is lacking. As such, this paper presents an example of present-day environmental policy making in action.

    A conceptual framework is presented for describing selected urban and community impacts of Federal energy policies. The framework depends on a simple causal model. The outputs of the model are impacts, changes in the state of the world of particular interest to policymakers. At any given time, a set of determinants account for the state of the world with respect to an impact category. Application of the model to a particular impact category requires: establishing a definition and measure for the impact category and identifying the determinants of these impacts. Analysis of the impact of a particular policy requires the following: identifying the policy and its effects (as estimated by others), isolating any effects that themselves constitute an urban and community impact, identifying any effects that change the value of determinants, and describing the impact with reference to the new values of determinants. This report provides a framework for these steps. Three impacts addressed are: neighborhood stability, housing availability, and quality and availability of public services. In each chapter, a definition and measure for the impact are specified; its principal determinants are identified; how the causal model can be used to estimate impacts by applying it to three illustrative Federal policies (domestic oil price decontrol, building energy performance standards, and increased Federal aid for mass transit) is demonstrated.

    The potential effects of air pollution are a major concern both in terms of the environment and in relation to human health. In order to support both environmental and health policy there is a need for accurate estimates of the exposures that populations might experience. The information for this typically comes from environmental monitoring networks but often the locations of monitoring sites are preferentially located in order to detect high levels of pollution. Using the information from such networks has the potential to seriously affect the estimates of pollution that are obtained and that might be used in health risk analyses. In this context, we explore the topic of preferential sampling within a long-standing network in the UK that monitored black smoke due to concerns about its effect on public health, the extent of which came to prominence during the famous London fog of 1952. Abatement measures led to a decline in the levels of black smoke and a subsequent reduction in the number of monitoring locations that were thought necessary to provide the information required for policy support. There is evidence of selection bias during this process with sites being kept in the most polluted areas. We assess the potential for this to affect the estimates of risk associated air pollution and show how using Bayesian spatio-temporal exposure models may be used to attempt to mitigate the effects of preferential sampling in this case.

    Much of the cost associated with marker discovery for marker assisted breeding (MAB) can be eliminated if a diverse, segregating population is generated, genotyped, and made available to the global breeding community. Herein, we present an example of a hybrid, wild-derived family of the octoploid strawberry that can be used by other breeding programs to economically find and tag useful genes for MAB. A pseudo test cross population between two wild species of Fragaria virginiana and F. chiloensis (FVC 11) was generated and evaluated for a set of phenotypic traits. A total of 106 individuals in the FVC 11 were genotyped for 29,251 single nucleotide polymorphisms (SNPs) utilizing a commercially available, genome-wide scanning platform (Affymetrix Axiom IStraw90(TW)). The marker trait associations were deduced using TASSEL software. The FVC 11 population segregating for daughters per mother, inflorescence number, inflorescence height, crown production, flower number, fruit size, yield, internal color, soluble solids, fruit firmness, and plant vigor. Coefficients of variations ranged from 10% for fruit firmness to 68% for daughters per mother, indicating an underlying quantitative inheritance for each trait. A total of 2,474 SNPs were found to be polymorphic in FVC 11 and strong marker trait associations were observed for vigor, daughters per mother, yield and fruit weight. These data indicate that FVC 11 can be used as a reference population for quantitative trait loci detection and subsequent MAB across different breeding programs and geographical locations.

    This study provides new information on basic policy theory that deals with resource management in Missouri. Four goals are used. First, resource policy systems in other states are reviewed to identify similar policy frameworks. Second, the policy framework that exists in Missouri is identified and used as a standard against which changes in resource policy can be measured. Third, Missouri policy is compared to that in other states. Lastly, improvements to the Missouri policy systems are suggested. The study consists of an inventory of the resource policy of the Departments of Natural Resources and Conservation, which are analyzed for discrepancies that weaken sound policy or prevent its development in the first place. The Annual Reports, Annual Budgets, and Management By Objective statements are used as sources of policy information. The conclusions reached are that, first, state resource policy development and implementation is inadequate to function effectively. Second, policy problems are compounded by the synergistic effect created by their presence in a bureaucracy. Third, state government has a questionable commitment to natural resource policy development, and lastly, agencies should be more responsible concerning resource policy.

  5. High throughput genome-specific and gene-specific molecular markers for erucic acid genes in Brassica napus (L.) for marker-assisted selection in plant breeding.

    A single base change in the Bn-FAE1.1 gene in the A genome and a two-base deletion in the Bn-FAE1.2 gene in the C genome produce the nearly zero content of erucic acid observed in canola. A BAC clone anchoring Bn-FAE1.1 from a B. rapa BAC library and a BAC clone anchoring Bn-FAE1.2 from a B. oleracea BAC library were used in this research. After sequencing the gene flanking regions, it was found that the dissimilarity of the flanking sequences of these two FAE1 homologs facilitated the design of genome-specific primers that could amplify the corresponding genome in allotetraploid B. napus. The two-base deletion in the C genome gene was detected as a sequence-characterized amplified region (SCAR) marker. To increase the throughput, one genome-specific primer was labeled with four fluorescence dyes and combined with 20 different primers to produce PCR products with different fragment sizes. Eventually, a super pool of 80 samples was detected simultaneously. This dramatically reduces the cost of marker detection. The single base change in the Bn-FAE1.1 gene was detected as single nucleotide polymorphic (SNP) marker with an ABI SNaPshot kit. A multiplexing primer set was designed by adding a polyT to the 5' primer end to increase SNP detection throughput through sample pooling. Furthermore, the Bn-FAE1.1 and Bn-FAE1.2 were integrated into the N8 and N13 linkage groups of our previously reported high-density sequence-related amplified polymorphism (SRAP) map, respectively. There were 124 SRAP markers in a N8 bin in which the Bn-FAE1.1 gene-specific SCAR marker was located and 46 SRAP markers in a N13 bin into which the Bn-FAE1.2 SNP marker was integrated. These three kinds of high throughput molecular markers have been successfully implemented in our canola/rapeseed breeding programs.

    The use of major resistance genes is a cost-effective strategy for preventing stem rust epidemics in wheat crops. The stem rust resistance gene Sr39 provides resistance to all currently known pathotypes of Puccinia graminis f. sp. tritici (Pgt) including Ug99 (TTKSK) and was introgressed together with leaf rust resistance gene Lr35 conferring adult plant resistance to P. triticina (Pt), into wheat from Aegilops speltoides. It has not been used extensively in wheat breeding because of the presumed but as yet undocumented negative agronomic effects associated with Ae. speltoides chromatin. This investigation reports the production of a set of recombinants with shortened Ae. speltoides segments through induction of homoeologous recombination between the wheat and the Ae. speltoides chromosome. Simple PCR-based DNA markers were developed for resistant and susceptible genotypes (Sr39#22r and Sr39#50s) and validated across a set of recombinant lines and wheat cultivars. These markers will facilitate the pyramiding of ameliorated sources of Sr39 with other stem rust resistance genes that are effective against the Pgt pathotype TTKSK and its variants. PMID:19756473

    Green cloud data center has become a research hotspot of virtualized cloud computing architecture. And load balancing has also been one of the most important goals in cloud data centers. Since live virtual machine (VM) migration technology is widely used and studied in cloud computing, we have focused on location selection (migration policy) of live VM migration for power saving and load balancing. We propose a novel approach MOGA-LS, which is a heuristic and self-adaptive multiobjective optimization algorithm based on the improved genetic algorithm (GA). This paper has presented the specific design and implementation of MOGA-LS such as the design of the genetic operators, fitness values, and elitism. We have introduced the Pareto dominance theory and the simulated annealing (SA) idea into MOGA-LS and have presented the specific process to get the final solution, and thus, the whole approach achieves a long-term efficient optimization for power saving and load balancing. The experimental results demonstrate that MOGA-LS evidently reduces the total incremental power consumption and better protects the performance of VM migration and achieves the balancing of system load compared with the existing research. It makes the result of live VM migration more high-effective and meaningful.

    The recent proliferation of strategies designed to increase the use of research in health policy (knowledge exchange) demands better application of contemporary conceptual understandings of how research shapes policy. Predictive models, or action frameworks, are needed to organise existing knowledge and enable a more systematic approach to the selection and testing of intervention strategies. Useful action frameworks need to meet four criteria: have a clearly articulated purpose; be informed by existing knowledge; provide an organising structure to build new knowledge; and be capable of guiding the development and testing of interventions. This paper describes the development of the SPIRIT Action Framework. A literature search and interviews with policy makers identified modifiable factors likely to influence the use of research in policy. An iterative process was used to combine these factors into a pragmatic tool which meets the four criteria. The SPIRIT Action Framework can guide conceptually-informed practical decisions in the selection and testing of interventions to increase the use of research in policy. The SPIRIT Action Framework hypothesises that a catalyst is required for the use of research, the response to which is determined by the capacity of the organisation to engage with research. Where there is sufficient capacity, a series of research engagement actions might occur that facilitate research use. These hypotheses are being tested in ongoing empirical work.

  14. A proposal for science education policies in Lebanon based on trends in selected developed countries over the last twenty years

    Sarraf, Lina

    The present study examines science education policies in three selected developed countries and compares them with science education policies in Lebanon in order to identify their potential reform policies and practices applicable to Lebanon. The selection of the three countries, the U.S.A., U.K., and Japan, was based on the amount of time and effort devoted in these countries to improving and modernizing their science education policies and curricula. Three aspects of secondary science curriculum policy in the chosen countries were analyzed and compared with those of Lebanon. These were: aims and objectives; pattern of science program including the science curriculum, the amount of time allotted to the study of science and the content of school science subjects; and the organization of school science including science requirement for graduation from high school, teaching strategies and mode of examinations. The data collected for analysis from the three chosen countries showed that, unlike Lebanon, in the three developed countries: education is compulsory up to at least the age of 16; aims and objectives are stated clearly and carefully; science is an integrated subject in the first year of secondary level, then it becomes separated into chemistry, physics and biology. The content of science subjects emphasizes the method and process of science and its application to the society. Examinations are designed to evaluate students' learning in science in contrast to Lebanon where examinations are designed to discriminate among students.

    Drouet, L.; Bosetti, V.; Tavoni, M.

    2015-10-01

    Strategies for dealing with climate change must incorporate and quantify all the relevant uncertainties, and be designed to manage the resulting risks. Here we employ the best available knowledge so far, summarized by the three working groups of the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR5; refs , , ), to quantify the uncertainty of mitigation costs, climate change dynamics, and economic damage for alternative carbon budgets. We rank climate policies according to different decision-making criteria concerning uncertainty, risk aversion and intertemporal preferences. Our findings show that preferences over uncertainties are as important as the choice of the widely discussed time discount factor. Climate policies consistent with limiting warming to 2 °C above preindustrial levels are compatible with a subset of decision-making criteria and some model parametrizations, but not with the commonly adopted expected utility framework.

    Albert, Michael A; Fretheim, Atle; Maïga, Diadié

    2007-01-01

    Background Research findings are increasingly being recognized as an important input in the formation of health policy. There is concern that research findings are not being utilized by health policy-makers to the extent that they could be. The factors influencing the utilization of various types of research by health policy-makers are beginning to emerge in the literature, however there is still little known about these factors in developing countries. The object of this study was to explore these factors by examining the policy-making process for a pharmaceutical policy common in developing countries; an essential medicines list. Methods A study of the selection and updating of Mali's national essential medicines list was undertaken using qualitative methods. In-depth semi-structured interviews and a natural group discussion were held with national policy-makers, most specifically members of the national commission that selects and updates the country's list. The resulting text was analyzed using a phenomenological approach. A document analysis was also performed. Results Several factors emerged from the textual data that appear to be influencing the utilization of health research findings for these policy-makers. These factors include: access to information, relevance of the research, use of research perceived as a time consuming process, trust in the research, authority of those who presented their view, competency in research methods, priority of research in the policy process, and accountability. Conclusion Improving the transfer of research to policy will require effort on the part of researchers, policy-makers, and third parties. This will include: collaboration between researchers and policy-makers, increased production and dissemination of relevant and useful research, and continued and improved technical support from networks and multi-national organizations. Policy-makers from developing countries will then be better equipped to make informed decisions

    1999-01-01

    Professionals should reexamine negative assumptions about the quality of life with prenatally detectable impairments and should reform clinical practice and public policy to improve informed decision making and genuine reproductive choice. Current data on children and families affected by disabilities indicate that disability does not preclude a satisfying life. Many problems attributed to the existence of a disability actually stem from inadequate social arrangements that public health professionals should work to change. This article assumes a pro-choice perspective but suggests that unreflective uses of prenatal testing could diminish, rather than expand, women's choices. This critique challenges the view of disability that lies behind the social endorsement of such testing and the conviction that women will or should end their pregnancies if they discover that the fetus has a disabling trait.

  9. Towards an ethical policy for the prevention of fetal sex selection in Canada.

    PubMed

    Thiele, Allison T; Leier, Brendan

    2010-01-01

    The troubling practice of fetal sex selection has historically been considered an Asian phenomenon. However, recent evidence shows that a similar situation is emerging in North America, albeit on a smaller scale. The Society of Obstetricians and Gynaecologists of Canada has firmly stated its opposition to sex selection for non-medical reasons, as well as to the use of any technology used solely for the purpose of determining fetal sex. However, because fetal sex may be disclosed to the parents at the time of ultrasound examination if they request this information, guidance for health care professionals to assist in discouraging fetal sex selection would be useful. Because no declaration of motives or reasons is required when a woman seeks a termination of pregnancy, we suggest that health care professionals need not disclose the sex of a fetus until it has reached a gestational age at which abortion for non-medical purposes would not be possible. This proposal would facilitate consistency between clinical practice and the values of Canadian citizens, the SOGC, the Canadian Medical Association, and other professional organizations, while still respecting current laws pertaining to disclosure of patient information and patients' rights to autonomous decision-making.

    Stevens, J.J.

    1996-12-01

    Following the breakdown of the Soviet Union, one of the world`s strongest oil producing industries was divided into a few major oil provinces. The process of change to the former Soviet oil industry including: Russian efforts to maintain control of its former resources, NIS resource development, Western capital investment, and environmental issues in the major oil provinces of the former Soviet Union, is the main focus of this thesis. Free market world oil majors and their counterparts, both in Russia and the New Independent States (NIS), have developed a number of significant alliances that have resulted in several potentially lucrative joint ventures. The coercive tactics that the Russian government resorts to in an effort to prevent its former republics from efficiently developing their reserves, and the position the United States must take to ensure these efforts are stifled will be addressed. A sound grasp of these critical energy issues by American policy makers will result in the development of these vast resources in a manner favorable to U. S. national interests.

    Groundwater is crucial for the livelihoods and food security of millions of people, and yet, knowledge formation in the field of groundwater has remained asymmetrical. While, scientific knowledge in the discipline (hydrology and hydrogeology) has advanced remarkably, relatively little is known about the socio-economic impacts and institutions that govern groundwater use. This paper therefore has two objectives. The first is to provide a balanced view of the plus and the down side of groundwater use, especially in agriculture. In doing so, examples are drawn from countries such as India, Pakistan, Bangladesh, China, Spain and Mexico—all of which make very intensive use of groundwater. Second, institutions and policies that influence groundwater use are analyzed in order to understand how groundwater is governed in these countries and whether successful models of governance could be replicated elsewhere. Finally, the authors argue that there is a need for a paradigm shift in the way groundwater is presently perceived and managed—from management to governance mode. In this attempt, a number of instruments such as direct regulation, indirect policy levers, livelihood adaptation and people's participation will have to be deployed simultaneously in a quest for better governance.

    2014-10-01

    This paper describes the methods used to investigate variations in total alcoholic beverage consumption as related to selected control intervention policies and other socioeconomic factors (unplanned factors) within 12 European countries involved in the AMPHORA project. The analysis presented several critical points: presence of missing values, strong correlation among the unplanned factors, long-term waves or trends in both the time series of alcohol consumption and the time series of the main explanatory variables. These difficulties were addressed by implementing a multiple imputation procedure for filling in missing values, then specifying for each country a multiple regression model which accounted for time trend, policy measures and a limited set of unplanned factors, selected in advance on the basis of sociological and statistical considerations are addressed. This approach allowed estimating the "net" effect of the selected control policies on alcohol consumption, but not the association between each unplanned factor and the outcome.

    Background The Department of Health in Western Australia identified access to, and daily consumption of recommended amounts of fruit and vegetables, as priority health determinants. The numerous factors that influence supply and consumption of fruit and vegetables indicated that a comprehensive approach would be required. A government and non-government sector steering group was set up to select priority interventions using the National Public Health Partnership's Framework for Implementing Public Health Strategies. This structured framework was used for developing strategies to improve fruit and vegetable consumption and supply, and to identify implementation priorities. After one year a desktop audit of progress on framework interventions was undertaken. Results The structured framework led to a plan for defined actions, partners, costs, and performance indicators for strategies to improve fruit and vegetable consumption and supply. Lead agency custodians for management of the selected interventions were identified. After one year there was significant progress in the implementation of a number of the high-ranking interventions. The exception was interventions that provide the infrastructure support such as research and development capacity, information systems. Conclusion A structured framework and stakeholder participation assisted in developing a fruit and vegetable implementation strategy. Engagement and commitment of influential and diverse stakeholders is needed, not just for program support, but particularly in the areas of food and nutrition policy development and providing the infrastructure support required. Further work is required to develop performance outcomes and cost effectiveness measures for many of the strategies that have been proposed to address portfolio objectives. PMID:19108736

    Morphology-based taxonomy via exiguously reproductive organ has severely limitation on bamboo taxonomy, mainly owing to infrequent and unpredictable flowering events of bamboo. Here, we present the first genome-wide analysis and application of microsatellites based on the genome of moso bamboo (Phyllostachys edulis) to assist bamboo taxonomy. Of identified 127,593 microsatellite repeat-motifs, the primers of 1,451 microsatellites were designed and 1,098 markers were physically mapped on the genome of moso bamboo. A total of 917 markers were successfully validated in 9 accessions with ~39.8% polymorphic potential. Retrieved from validated microsatellite markers, 23 markers were selected for polymorphic analysis among 78 accessions and 64 alleles were detected with an average of 2.78 alleles per primers. The cluster result indicated the majority of the accessions were consistent with their current taxonomic classification, confirming the suitability and effectiveness of the developed microsatellite markers. The variations of microsatellite marker in different species were confirmed by sequencing and in silico comparative genome mapping were investigated. Lastly, a bamboo microsatellites database (http://www.bamboogdb.org/ssr) was implemented to browse and search large information of bamboo microsatellites. Consequently, our results of microsatellite marker development are valuable for assisting bamboo taxonomy and investigating genomic studies in bamboo and related grass species. PMID:25620112

  5. Advances and Challenges in Genomic Selection for Disease Resistance.

    Breeding for disease resistance is a central focus of plant breeding programs, as any successful variety must have the complete package of high yield, disease resistance, agronomic performance, and end-use quality. With the need to accelerate the development of improved varieties, genomics-assisted breeding is becoming an important tool in breeding programs. With marker-assisted selection, there has been success in breeding for disease resistance; however, much of this work and research has focused on identifying, mapping, and selecting for major resistance genes that tend to be highly effective but vulnerable to breakdown with rapid changes in pathogen races. In contrast, breeding for minor-gene quantitative resistance tends to produce more durable varieties but is a more challenging breeding objective. As the genetic architecture of resistance shifts from single major R genes to a diffused architecture of many minor genes, the best approach for molecular breeding will shift from marker-assisted selection to genomic selection. Genomics-assisted breeding for quantitative resistance will therefore necessitate whole-genome prediction models and selection methodology as implemented for classical complex traits such as yield. Here, we examine multiple case studies testing whole-genome prediction models and genomic selection for disease resistance. In general, whole-genome models for disease resistance can produce prediction accuracy suitable for application in breeding. These models also largely outperform multiple linear regression as would be applied in marker-assisted selection. With the implementation of genomic selection for yield and other agronomic traits, whole-genome marker profiles will be available for the entire set of breeding lines, enabling genomic selection for disease at no additional direct cost. In this context, the scope of implementing genomics selection for disease resistance, and specifically for quantitative resistance and quarantined pathogens

  1. Policy implications of select student characteristics and their influence on the Florida biology end-of-course assessment

    NASA Astrophysics Data System (ADS)

    Bertolotti, Janine Cecelia

    In an attempt to improve student achievement in science in Florida, the Florida Department of Education implemented end-of-course (EOC) assessments in biology during the 2011-2012 academic school year. Although this first administration would only account for 30% of the student's overall final course grade in biology, subsequent administrations would be accompanied by increasing stakes for students, teachers, and schools. Therefore, this study sought to address gaps in empirical evidence as well as discuss how educational policy will potentially impact on teacher evaluation and professional development, student retention and graduation rates, and school accountability indicators. This study explored four variables- reading proficiency, ethnicity, socioeconomic status, and gender- to determine their influence and relationship on biology achievement on the Biology I EOC assessment at a Title 1 school. To do so, the results of the Biology I EOC assessment administered during the Spring 2012 school year was obtained from a small, rural Title 1 high school in North Florida. Additional data regarding each student's qualification for free and reduced-price lunch, FCAT Reading developmental scale scores, FCAT Reading level, grade level, gender, and ethnicity were also collected for the causal-comparative exploratory study. Of the 178 students represented, 48% qualified for free and reduced-price lunch, 54% were female, and 55% scored at FCAT Reading level 3 or higher. Additionally, 59% were White and 37% Black. A combination of descriptive statistics and other statistical procedures such as independent samples one-tailed t-test, one-way ANOVAs, ANCOVAs, multipleregression, and a Pearson r correlation was utilized in the analysis, with a significance level set at 0.05. Results indicate that of all four variables, FCAT Reading proficiency was the sole variable, after adjusting for other variables; that had a significant impact on biology achievement.

    The development of policies and procedures is an integral part of the occupational health nurse's role. Policies and procedures serve as the foundation for the occupational health service and are based on its vision, mission, culture, and values. The design and layout selected for the policies and procedures should be simple, consistent, and easy to use. The same format should be used for all existing and new policies and procedures. Policies and procedures should be reviewed periodically based on a specified time frame (i.e., annually). However, some policies may require a more frequent review if they involve rapidly changing external standards, ethical issues, or emerging exposures. PMID:17124968

  11. Climate policy decisions require policy-based lifecycle analysis.

    PubMed

    Bento, Antonio M; Klotz, Richard

    2014-05-20

    Lifecycle analysis (LCA) metrics of greenhouse gas emissions are increasingly being used to select technologies supported by climate policy. However, LCAs typically evaluate the emissions associated with a technology or product, not the impacts of policies. Here, we show that policies supporting the same technology can lead to dramatically different emissions impacts per unit of technology added, due to multimarket responses to the policy. Using a policy-based consequential LCA, we find that the lifecycle emissions impacts of four US biofuel policies range from a reduction of 16.1 gCO2e to an increase of 24.0 gCO2e per MJ corn ethanol added by the policy. The differences between these results and representative technology-based LCA measures, which do not account for the policy instrument driving the expansion in the technology, illustrate the need for policy-based LCA measures when informing policy decision making.

    Calls to increase the demographic representativeness of medical classes to better reflect the diversity of society are part of a growing international trend. Despite this, entry into medical school remains highly competitive and exclusive of marginalized groups. To address these questions, we conducted a Foucauldian discourse analysis of 15 publically available policy documents from the websites of Canadian medical education regulatory bodies, using the concepts of "excellence" (institutional or in an applicant), "diversity," and "equity" to frame the analysis. In most documents, there were appeals to broaden definitions of institutional excellence to include concerns for greater social accountability. Equity concerns tended to be represented as needing to be dealt with by people in positions of authority in order to counter a "hidden curriculum." Diversity was represented as an object of value, situated within a discontinuous history. As a rhetorical strategy, documents invoked complex societal shifts to promote change toward a more humanistic medical education system and profession. "Social accountability" was reified as an all-encompassing solution to most issues of representation. Although the policy documents proclaimed rootedness in an ethos of improving the societal responsiveness of the medical profession, our analysis takes a more critical stance towards the discourses identified. On the basis of our research findings, we question whether these calls may contribute to the maintenance of the specific power relations they seek to address. These conclusions lead us to consider the possibility that the discourses represented in the documents might be reframed to take into account issues of power distribution and its productive and reproductive features. A reframing of discourses could potentially generate greater inclusiveness in policy development processes, and afford disadvantaged and marginalized groups more participatory roles in the discussion.

    CO2 capture and storage (CCS) is rapidly emerging as a potential key climate change mitigation option. However, as policymakers and industrial stakeholders begin the process of formulating new policy for implementing CCS technologies, participants require a tool to assess large-scale CCS deployment over a number of different possible future scenarios. This paper will analyze several scenarios using two state-of-the-art Battelle developed models, the MiniCAM and the CO2-GIS for examining CCS deployment. Outputs include the total amount of CO2 captured, total annual emissions, and fossil-based generating capacity.

    This study confirms that during the decades following WW II there was a tendency towards closure of consumption of alcoholic beverages among the European countries. The Northern countries, which during the 1960s manifested the lowest rates of alcohol consumption, ended up with greater consumption rates than the Southern countries, manifested the opposite trend; greater amounts of consumptions in the 1960s and lower consumptions in the 2000s. During the same some period, social, demographic and economic indicators--urbanization, rate of elderly males, Income, female education, female employment and mother's age at their childbirths, tended to increase, while the alcoholic beverage control policy strategies showed differences according to the country. Liver disease-related mortality, decreased in most countries. Study limitations are noted.

    Snowden, Daniel Eugene

    The Interstate 99 (I-99) highway project has been the source of extensive attention over the past few years. Its most infamous aspect is the excavation of a geological formation---the Bald Eagle Sandstone---that was found to contain acidic rock material, which, upon exposure to water, leached sulfuric acid to several surface water bodies and private groundwater wells. This matter managed to suspend construction of the project for several years. Numerous parties, representing academia, government (particularly the Pennsylvania Department of Environmental Protection (PA DEP) and the Pennsylvania Department of Transportation (PennDOT)), private industry (consultants), environmental organizations and advocacy groups, and the citizenry, have been involved in the development of a resolution to the I-99 acidic rock problem. The interactions among these parties are interdisciplinary by nature, given the sectors of society that they represent. Consideration of how these parties interacted with each other while evaluating the options for addressing the environmental dilemma posed by the I-99 project provides opportunities for academic research. The discipline of Science Education is viable for studying the I-99 case, with accompaniment by 2 other disciplines, which have direct relevance to this case: Geology/Earth Science (per the underlying cause of the I-99 acidic rock problem) and Environmental Policy (per the regulations and policies that had to be followed while developing a solution to the environmental dilemma). Pairing Science Education with the other two aforementioned disciplines can create additional niches for the former discipline, and enhance academic research both within itself, and, across other disciplines, as relevant.

  12. Policy Capacity Is Necessary but Not Sufficient

    PubMed Central

    Gen, Sheldon; Wright, Amy Conley

    2015-01-01

    Policy capacity focuses on the managerial and organizational abilities to inform policy decisions with sound research and analysis, and facilitate policy implementation with operational efficiency. It stems from a view of the policy process that is rational and positivistic, in which optimal policy choices can be identified, selected, and implemented with objectivity. By itself, however, policy capacity neglects the political aspects of policy-making that can dominate the process, even in health policies. These technical capabilities are certainly needed to advance reforms in health policies, but they are not sufficient. Instead, they must be complemented with public engagement and policy advocacy to ensure support from the public that policies are meant to serve. PMID:26673469

    STUDY QUESTION Is an elective single-embryo transfer (eSET) policy an efficient approach for women aged >35 years when embryo selection is enhanced via blastocyst culture and preimplantation genetic screening (PGS)? SUMMARY ANSWER Elective SET coupled with enhanced embryo selection using PGS in women older than 35 years reduced the multiple pregnancy rates while maintaining the cumulative success rate of the IVF programme. WHAT IS KNOWN ALREADY Multiple pregnancies mean an increased risk of premature birth and perinatal death and occur mainly in older patients when multiple embryos are transferred to increase the chance of pregnancy. A SET policy is usually recommended in cases of good prognosis patients, but no general consensus has been reached for SET application in the advanced maternal age (AMA) population, defined as women older than 35 years. Our objective was to evaluate the results in terms of efficacy, efficiency and safety of an eSET policy coupled with increased application of blastocyst culture and PGS for this population of patients in our IVF programme. STUDY DESIGN, SIZE, DURATION In January 2013, a multidisciplinary intervention involving optimization of embryo selection procedure and introduction of an eSET policy in an AMA population of women was implemented. This is a retrospective 4-year (January 2010–December 2013) pre- and post-intervention analysis, including 1161 and 499 patients in the pre- and post-intervention period, respectively. The primary outcome measures were the cumulative delivery rate (DR) per oocyte retrieval cycle and multiple DR. PARTICIPANTS/MATERIALS, SETTING, METHODS Surplus oocytes and/or embryos were vitrified during the entire study period. In the post-intervention period, all couples with good quality embryos and less than two previous implantation failures were offered eSET. Embryo selection was enhanced by blastocyst culture and PGS (blastocyst stage biopsy and 24-chromosomal screening). Elective SET was also

    Davis, G P; DeNise, S K

    1998-09-01

    Genetic marker technologies, such as marker-assisted selection, parentage identification, and gene introgression can be applied to livestock selection programs. Highly saturated genetic maps are now available for cattle, swine, and sheep to provide the genetic framework for developing MAS programs. These programs rely on three phases for commercialization of the technology: the detection phase, in which quantitative trait loci are located and their effects on the phenotype measured; the evaluation phase, in which the markers are evaluated in commercial populations; and the implementation phase, in which markers are combined with phenotypic and pedigree information in genetic evaluation for predicting the genetic merit of individuals within the population. Predicting the economic impact of genetic technologies is a complex process that requires quantitative prediction and economic analysis. Evaluating the impact of these benefits across an industry can be achieved through a process in which gains from implementation of a genetic technology are assessed at the individual, enterprise, and industry levels. A pattern of annual benefits and costs can be predicted using gene flows that can be evaluated by conventional economic analysis.

    1987-03-01

    Participants in the Seminar on Population Policies for Top-level Policy Makers and Program Managers, meeting in Thailand during January 1987, examined the challenges now facing them regarding the implementation of fertility regulation programs in their respective countries -- Bangladesh, China, India, Indonesia, Malaysia, Nepal, Pakistan, the Philippines, the Republic of Korea, and Thailand. This Seminar was organized to coincide with the completion of an Economic and Social Commission for Asia and the Pacific (ESCAP) study investigating the impact and efficiency of family planning programs in the region. Country studies were reviewed at the Seminar along with policy issues about the status of women, incentive and disincentive programs, and socioeconomic factors affecting fertility. In Bangladesh the government recognizes population growth as its top priority problem related to the socioeconomic development of the country and is working to promote a reorientation strategy from the previous clinic-oriented to a multidimensional family welfare program. China's family planning program seeks to postpone marraige, space the births of children between 3-5 years, and promote the 1-child family. Its goal is to reduce the rate of natural increase from 12/1000 in 1978 to 5/1000 by 1985 and 0 by 2000. India's 7th Five-Year-Plan (1986-90) calls for establishing a 2-child family norm by 2000. In Indonesia the government's population policy includes reducing the rate of population growth, achieving a redistribution of the population, adjusting economic factors, and creating prosperous families. The government of Indonesia reversed its policy to reduce the population growth rate in 1984 and announced its goal of achieving a population of 70 million by 2100 in order to support mass consumption industries. It has created an income tax deduction system favoring large families and maternity benefits for women who have up to 5 children as incentives. Nepal's official policy is to

    2010-01-01

    Health has long been intertwined with the foreign policies of states. In recent years, however, global health issues have risen to the highest levels of international politics and have become accepted as legitimate issues in foreign policy. This elevated political priority is in many ways a welcome development for proponents of global health, and it has resulted in increased funding for and attention to select global health issues. However, there has been less examination of the tensions that characterize the relationship between global health and foreign policy and of the potential effects of linking global health efforts with the foreign-policy interests of states. In this paper, the authors review the relationship between global health and foreign policy by examining the roles of health across 4 major components of foreign policy: aid, trade, diplomacy, and national security. For each of these aspects of foreign policy, the authors review current and historical issues and discuss how foreign-policy interests have aided or impeded global health efforts. The increasing relevance of global health to foreign policy holds both opportunities and dangers for global efforts to improve health. PMID:20423936

    The Internet is now widely regarded as essential infrastructure for our global economy and society. It is in our homes and businesses. We use it to communicate and socialize, for research, and as a platform for E-commerce. In the late 1990s, much was predicted about what the Internet has become at present; but now, we have actual experience living with the Internet as a critical component of our everyday lives. Although the Internet has already had profound effects, there is much we have yet to realize. The present volume represents a third installment in a collaborative effort to highlight the all-encompassing, multidisciplinary implications of the Internet for public policy. The first installment was conceived in 1998, when we initiated plans to organize an international conference among academic, industry, and government officials to discuss the growing policy agenda posed by the Internet. The conference was hosted by the European Commission in Brussels in 1999 and brought together a diverse mix of perspectives on what the pressing policy issues would be confronting the Internet. All of the concerns identified remain with us today, including how to address the Digital Divide, how to modify intellectual property laws to accommodate the new realities of the Internet, what to do about Internet governance and name-space management, and how to evolve broadcast and telecommunications regulatory frameworks for a converged world.

  8. Policy Driven Development: Flexible Policy Insertion for Large Scale Systems.

    Demchak, Barry; Krüger, Ingolf

    2012-07-01

    The success of a software system depends critically on how well it reflects and adapts to stakeholder requirements. Traditional development methods often frustrate stakeholders by creating long latencies between requirement articulation and system deployment, especially in large scale systems. One source of latency is the maintenance of policy decisions encoded directly into system workflows at development time, including those involving access control and feature set selection. We created the Policy Driven Development (PDD) methodology to address these development latencies by enabling the flexible injection of decision points into existing workflows at runtime, thus enabling policy composition that integrates requirements furnished by multiple, oblivious stakeholder groups. Using PDD, we designed and implemented a production cyberinfrastructure that demonstrates policy and workflow injection that quickly implements stakeholder requirements, including features not contemplated in the original system design. PDD provides a path to quickly and cost effectively evolve such applications over a long lifetime. PMID:25383258

  12. Policy implications for familial searching

    PubMed Central

    2011-01-01

    In the United States, several states have made policy decisions regarding whether and how to use familial searching of the Combined DNA Index System (CODIS) database in criminal investigations. Familial searching pushes DNA typing beyond merely identifying individuals to detecting genetic relatedness, an application previously reserved for missing persons identifications and custody battles. The intentional search of CODIS for partial matches to an item of evidence offers law enforcement agencies a powerful tool for developing investigative leads, apprehending criminals, revitalizing cold cases and exonerating wrongfully convicted individuals. As familial searching involves a range of logistical, social, ethical and legal considerations, states are now grappling with policy options for implementing familial searching to balance crime fighting with its potential impact on society. When developing policies for familial searching, legislators should take into account the impact of familial searching on select populations and the need to minimize personal intrusion on relatives of individuals in the DNA database. This review describes the approaches used to narrow a suspect pool from a partial match search of CODIS and summarizes the economic, ethical, logistical and political challenges of implementing familial searching. We examine particular US state policies and the policy options adopted to address these issues. The aim of this review is to provide objective background information on the controversial approach of familial searching to inform policy decisions in this area. Herein we highlight key policy options and recommendations regarding effective utilization of familial searching that minimize harm to and afford maximum protection of US citizens. PMID:22040348

    2015-01-01

    Food Policy Councils (FPC) help to identify and address the priorities of local, state, and regional food systems with the goal of improving food systems through policy. There is limited research describing FPCs’ strategies for accomplishing this goal. As part of a larger study examining FPC policy efforts, this paper investigates the role of partnerships in food systems policy change. We conducted interviews with representatives from 12 purposefully selected FPCs in the United States and 6 policy experts identified by the selected FPC representatives to document and describe their policy work. One theme that emerged from those interviews was the role of partners. Interviewees described a range of partners (e.g., stakeholders from government, business, and education) and credited FPC partnerships with advancing their policy goals by increasing the visibility and credibility of FPCs, focusing their policy agenda, connecting FPCs to key policy inputs (e.g., local food community knowledge and priorities), and obtaining stakeholder buy-in for policy initiatives. Partnerships were also described as barriers to policy progress when partners were less engaged or had either disproportionate or little influence in a given food sector. Despite these challenges, partnerships were found to be valuable for FPCs efforts to effectively engage in the food policy arena. PMID:25856089

Over time, however, it has evolved into a system that creates substantial health impacts, both directly and indirectly. By generating more profit for food producers and less for family farmers; by effectively subsidizing the production of lower-cost fats, sugars, and oils that intensify the health-destroying obesity epidemic; by amplifying environmentally destructive agricultural practices that impact air, water, and other resources, the Farm Bill influences the health of Americans more than is immediately apparent. In this article, we outline three major public health issues influenced by American farm policy. These are (1) rising obesity; (2) food safety; and (3) environmental health impacts, especially exposure to toxic substances and pesticides. PMID:23144677

    Broken and cracked eggshells are major causes of significant economic losses to the egg production industry. The quantitative trait loci (QTL) on chromosome 9 influencing the quality of eggshells were identified by analysing an intercross between two parent lines developed from the same founder population by a two-way selection for eggshell strength with non-destructive deformation conducted over 14 generations. Chromosome-wide highly significant (P < 0.01) QTL associated with egg weight (EW), short length of egg (SLE), long length of egg (LLE) and eggshell weight were mapped to the distal region of chromosome 9. Among the QTL affecting EW, SLE and LLE, ovocalyxin-32 was identified as a potential candidate gene influencing eggshell traits. Marker-assisted selection based on these QTL could be used to develop strategies for reducing the breakage and cracking of eggs in commercial layer houses. PMID:19780721

    In his 14 January 2004 speech on the future of space exploration, U.S. President George W. Bush proposed a return to the Moon followed by ``human missions to Mars and to worlds beyond.'' Bush's proposal called for robotic missions and new manned space vehicles to replace an aging set of space shuttles, and sought a new justification for space exploration. In the words of former NASA Administrator Sean O'Keefe, in The Vision for Space Exploration, this plan is not ``merely for the sake of adventure, however exciting that might be, but seeks answers to profound scientific and philosophic questions.'' Bush's proposal stimulated renewed reflection on the goals of our nation's space policy and on the means (financial and otherwise) for achieving these goals. A return to such first-order questioning of our goals for space has been long overdue. The Columbia Accident Investigation Board, which was convened by NASA in 2003 following the shuttle disaster, described ``a lack, over the past three decades, of any national mandate providing NASA a compelling mission requiring human presence in space'' [Keiper, 2003].

  19. Mapping quantitative trait loci in selected breeding populations: A segregation distortion approach.

    2015-12-01

    Quantitative trait locus (QTL) mapping is often conducted in line-crossing experiments where a sample of individuals is randomly selected from a pool of all potential progeny. QTLs detected from such an experiment are important for us to understand the genetic mechanisms governing a complex trait, but may not be directly relevant to plant breeding if they are not detected from the breeding population where selection is targeting for. QTLs segregating in one population may not necessarily segregate in another population. To facilitate marker-assisted selection, QTLs must be detected from the very population which the selection is targeting. However, selected breeding populations often have depleted genetic variation with small population sizes, resulting in low power in detecting useful QTLs. On the other hand, if selection is effective, loci controlling the selected trait will deviate from the expected Mendelian segregation ratio. In this study, we proposed to detect QTLs in selected breeding populations via the detection of marker segregation distortion in either a single population or multiple populations using the same selection scheme. Simulation studies showed that QTL can be detected in strong selected populations with selected population sizes as small as 25 plants. We applied the new method to detect QTLs in two breeding populations of rice selected for high grain yield. Seven QTLs were identified, four of which have been validated in advanced generations in a follow-up study. Cloned genes in the vicinity of the four QTLs were also reported in the literatures. This mapping-by-selection approach provides a new avenue for breeders to improve breeding progress. The new method can be applied to breeding programs not only in rice but also in other agricultural species including crops, trees and animals.

  4. Genome-wide association and genomic selection in animal breeding.

    PubMed

    Hayes, Ben; Goddard, Mike

    2010-11-01

    Results from genome-wide association studies in livestock, and humans, has lead to the conclusion that the effect of individual quantitative trait loci (QTL) on complex traits, such as yield, are likely to be small; therefore, a large number of QTL are necessary to explain genetic variation in these traits. Given this genetic architecture, gains from marker-assisted selection (MAS) programs using only a small number of DNA markers to trace a limited number of QTL is likely to be small. This has lead to the development of alternative technology for using the available dense single nucleotide polymorphism (SNP) information, called genomic selection. Genomic selection uses a genome-wide panel of dense markers so that all QTL are likely to be in linkage disequilibrium with at least one SNP. The genomic breeding values are predicted to be the sum of the effect of these SNPs across the entire genome. In dairy cattle breeding, the accuracy of genomic estimated breeding values (GEBV) that can be achieved and the fact that these are available early in life have lead to rapid adoption of the technology. Here, we discuss the design of experiments necessary to achieve accurate prediction of GEBV in future generations in terms of the number of markers necessary and the size of the reference population where marker effects are estimated. We also present a simple method for implementing genomic selection using a genomic relationship matrix. Future challenges discussed include using whole genome sequence data to improve the accuracy of genomic selection and management of inbreeding through genomic relationships.

  7. Policy issues in space analogues

    Auger, Robin N.; Facktor, Debra D.

    Space mission planning is increasingly focusing on destinations beyond Earth orbit. Advancements in technology will inevitably be required to enable long-duration human spaceflight missions, and breakthroughs in the policy arena will also be needed to achieve success in such missions. By exploring how policy issues have been addressed in analogous extreme environments, policymakers can develop a framework for addressing these issues as they apply to long-term human spaceflight. Policy issues that need to be addressed include: crew selection, training, organization, and activities, medical testing, illness, injury, and death; communication; legal accountability and liability; mission safety and risk management; and environmental contamination. This paper outlines the approach of a study underway by The George Washington University and ANSER to examine how these policy issues have been addressed in several analogues and how the experiences of these analogues can help formulate policies for long-duration human spaceflight missions. Analogues being studied include Antarctic bases, submarine voyages, undersea stations, Biosphere 2, and the U.S. Skylab and Russian Mir space stations.

    The tolerance of spring barley (Hordeum vulgare L.) cultivars to spring drought is an important agronomic trait affecting crop yield and quality in Poland. Therefore, breeders require new molecular markers to select plants with lower spring drought susceptibility. With the advent of genomic selection technology, simple molecular tools may still be applicable to screen material for markers of the most important traits and in-depth genome scanning. In previous studies, diversity arrays technology (DArT)-based genetic maps were constructed for F2 populations of Polish fodder and malt barley elite breeding lines, and 15 and 18 quantitative trait loci (QTLs) related to spring drought tolerance were identified, respectively. In this paper, we show the results of a conversion of 30 DArT markers corresponding to 11 QTLs into simple sequence repeat (SSR) and sequence tagged site (STS) markers. Twenty-two polymorphic markers were obtained, including 13 DArT-based SSRs. Additionally, 31 SSR markers, located in close proximity to the DArT markers, were selected from the GrainGenes database and tested. Further analyses of 24 advanced breeding lines with different drought tolerances confirmed that five out of the 30 converted markers, as well as three out of the 31 additional SSR markers, were effective in marker-assisted selection for drought tolerance. The possible function of clones related to these markers in drought tolerance is discussed. PMID:25716655

    Combining ability is crucial for parent selection in crop hybrid breeding. The present investigation and results had revealed the underlying genetic factors which might contribute in adequate combining ability, further assisting in enhancing heterosis and stability. Here, we conducted a large-scale analysis of genomic variation in order to define genomic regions affecting the combining ability in recurrent selection population of rapeseed. A population of 175 individuals was genotyped with the Brassica60K SNP chip. 525 hybrids were assembled with three different testers and used to evaluate the general combining ability (GCA) in three environments. By detecting the changes of the genomic variation, we identified 376 potential genome regions, spanning 3.03% of rapeseed genome which provided QTL-level resolution on potentially selected variants. More than 96% of these regions were located in the C subgenome, indicating that C subgenome had sustained stronger selection pressure in the breeding program than the A subgenome. In addition, a high level of linkage disequilibrium in rapeseed genome was detected, suggesting that marker-assisted selection for the population improvement might be easily implemented. This study outlines the evidence for high GCA on a genomic level and provided underlying molecular mechanism for recurrent selection improvement in B. napus. PMID:27412721

    1994-10-01

    Among the many methodologies encompassing biotechnology in aquaculture, this report addresses: the production of genetically modified aquatic organisms (aquatic GMOs) by gene transfer, chromosome set manipulation, or hybridization or protoplast fusion between species; new health management tools, including DNA-Based diagnostics and recombinant DNA vaccines; Marker-assisted selection; cryopreservation; and stock marking. These methodologies pose a wide range of potential economic benefits for aquaculture by providing improved or new means to affect the mix of necessary material inputs, enhance production efficiency, or improve product quality. Advances in aquaculture through biotechnology could simulate growth of the aquaculture industry to provide a larger proportion of consummer demand, and thereby reduce pressure and natural stocks from over-harvest. Judicious application of gamete cryopreservation and chromosome set manipulations to achieve sterilization could reduce environmental risks of some aquaculture operations. Given the significant losses to disease in many aquaculture enterprises, potential benefits of DNA-based health management tools are very high and appear to pose no major environmental risks or social concerns.

  15. Fisheries-induced disruptive selection.

    PubMed

    Landi, Pietro; Hui, Cang; Dieckmann, Ulf

    2015-01-21

    Commercial harvesting is recognized to induce adaptive responses of life-history traits in fish populations, in particular by shifting the age and size at maturation through directional selection. In addition to such evolution of a target stock, the corresponding fishery itself may adapt, in terms of fishing policy, technological progress, fleet dynamics, and adaptive harvest. The aim of this study is to assess how the interplay between natural and artificial selection, in the simplest setting in which a fishery and a target stock coevolve, can lead to disruptive selection, which in turn may cause trait diversification. To this end, we build an eco-evolutionary model for a size-structured population, in which both the stock׳s maturation schedule and the fishery׳s harvest rate are adaptive, while fishing may be subject to a selective policy based on fish size and/or maturity stage. Using numerical bifurcation analysis, we study how the potential for disruptive selection changes with fishing policy, fishing mortality, harvest specialization, life-history tradeoffs associated with early maturation, and other demographic and environmental parameters. We report the following findings. First, fisheries-induced disruptive selection is readily caused by commonly used fishing policies, and occurs even for policies that are not specific for fish size or maturity, provided that the harvest is sufficiently adaptive and large individuals are targeted intensively. Second, disruptive selection is more likely in stocks in which the selective pressure for early maturation is naturally strong, provided life-history tradeoffs are sufficiently consequential. Third, when a fish stock is overexploited, fisheries targeting only large individuals might slightly increase sustainable yield by causing trait diversification (even though the resultant yield always remains lower than the maximum sustainable yield that could be obtained under low fishing mortality, without causing disruptive

  17. [Energy policy rather than climate policy].

    PubMed

    2009-01-01

    Energy policy and climate policy are two different issues and should not be treated as if they were the same. Whether the climate gets warmer or colder, saving energy and developing sustainable forms of energy production remain of paramount importance because fossil hydrocarbons are likely to be exhausted soon. But climate policy is a fallacy: it is human arrogance to think we can control the climate by reducing emissions and by storing CO2 underground. In spite of rising CO2 levels, the climate has cooled down slightly over the past decade. Since the International Panel on Climate Change (IPCC) did not predict this, it is questionable whether they can reliably predict warming. Other factors such as solar activity are probably more important for climate than greenhouse gases. The danger of coupling energy policy to climate policy is evident: if the climate cools down, people will lose belief in the greenhouse effect and therefore also lose interest in saving energy.

    2012-12-01

    Food and agricultural policy is an essential element of a communicable disease policy. The European Union has developed a more systematic and broadly based interest in questions of food safety and animal health and welfare linked to modernization of the Common Agricultural Policy, reflected in a new treaty obligation on animal welfare. Following the bovine spongiform encephalopathy crisis, moves were made to create a European competency, but implementation and enforcement resources reside with the member states. The European Animal Health Strategy is meant to lead to an EU animal health law, but this has already been constrained by fiscal austerity. The development of such a law may lead to a lowest common denominator formula that does little to enhance consumer protection or improve animal welfare. This is an inherent risk with top-down forms of Europeanization; more attention should be paid to lessons to be learned from bottom-up initiatives of the type used to counteract the bovine diarrhea virus. There will always be a tension among what is good policy for reducing the incidence of communicable disease, policy that is popular with EU citizens, and policy that is acceptable to member states.

    The soybean cyst nematode (SCN) is a major cause of soybean yield reduction. The objective of this study was to evaluate the efficiency of marker-assisted selection to identify genotypes resistant to SCN race 3 infection, using Sat_168 and Sat-141 resistance quantitative trait loci. The experiment was carried out under greenhouse conditions, using soybean populations originated from crosses between susceptible and resistant parent stock: CD-201 (susceptible) and Foster IAC (resistant), Conquista (susceptible) and S83-30 (resistant), La-Suprema (susceptible) and S57-11 (resistant), and Parecis (susceptible) and S65-50 (resistant). Plants were inoculated with SCN and evaluated according to the female index (FI), those with FI < 10% were classified as resistant to nematode infection. Plants were genotyped for SCN resistance using microsatellite markers Sat-141 and Sat_168. Marker selection efficiency was analyzed by a contingency table, taking into account genotypic versus phenotypic evaluations for each line. These markers were shown to be useful tool for selection of SCN race 3.

    Parallel input/output characterization studies and experiments with flexible resource management algorithms indicate that adaptivity is crucial to file system performance. In this paper we propose an automatic technique for selecting and refining file system policies based on application access patterns and execution environment. An automatic classification framework allows the file system to select appropriate caching and pre-fetching policies, while performance sensors provide feedback used to tune policy parameters for specific system environments. To illustrate the potential performance improvements possible using adaptive file system policies, we present results from experiments involving classification-based and performance-based steering.

    Vaccines against specific types of human papillomavirus (HPV) linked to cancer and other diseases have been met with mixed acceptance globally and in the United States. Policy-level interventions have been shown to be effective in increasing public health benefit. Government policies and mandates may result in improved HPV vaccination coverage and reduced disease burden, and alternative policies that improve unhindered access to HPV vaccination may allow success as well. The purpose of this commentary is to summarize policy efforts to maximize the public health benefit of HPV vaccination. We examine selected examples of HPV vaccination policy in global contexts and in the United States.

    Although until April 2012, all Spanish citizens regardless of their origin, residence status and work situation were entitled to health care, available evidence suggested inadequate access for immigrants. Following the Aday and Andersen model, we conducted an analysis of policy elements that affect immigrants' access to health care in Spain, based on documentary analysis of national policies and selected regional policies related to migrant health care. Selected documents were (a) laws and plans in force at the time containing migrant health policies and (b) evaluations. The analysis included policy principles, objectives, strategies and evaluations. Results show that the national and regional policies analyzed are based on the principle that health care is a right granted to immigrants by law. These policies include strategies to facilitate access to health care, reducing barriers for entry to the system, for example simplifying requirements and raising awareness, but mostly they address the necessary qualities for services to be able to attend to a more diverse population, such as the adaptation of resources and programs, or improved communication and training. However, limited planning was identified in terms of their implementation, necessary resources and evaluation. In conclusion, the policies address relevant barriers of access for migrants and signal improvements in the health system's responsiveness, but reinforcement is required in order for them to be effectively implemented.

  12. Pronatalism and women's equality policies.

    PubMed

    Heitlinger, A

    1991-01-01

    Pronatalism, as an ideology, can mean many different things. In its worst version it is associated with imperialism, racism, eugenism, reinforcement of traditional family structures where the man is the income generator and the women is economically dependent. This version gives women severe limitation of reproductive choices and a selective combination of strong pronatalism for some and strong anti-natalism for others. In its best version, it is associated with policies supporting women's emancipation by making the role of mother more compatible with the role as income generator, and state assistance for families with children. According to McIntosh there are 4 barriers to creating and installing pronatalist policies: 1) lack of public demand, 2) distinct limits to government's ability to finance all of the public services and cash benefits, 3) doubts about the efficacy of financial incentives as a means of encouraging women to have more children, 4) a weak nationalist rationale.

    Clinical policies of professional societies such as the American Academy of Pediatrics are valued highly, not only by clinicians who provide direct health care to children but also by many others who rely on the professional expertise of these organizations, including parents, employers, insurers, and legislators. The utility of a policy depends, in large part, on the degree to which its purpose and basis are clear to policy users, an attribute known as the policy's transparency. This statement describes the critical importance and special value of transparency in clinical policies, guidelines, and recommendations; helps identify obstacles to achieving transparency; and suggests several approaches to overcome these obstacles.

    Selection signals of Korean cattle might be attributed largely to artificial selection for meat quality. Rapidly increased intragenic markers of newly annotated genes in the bovine genome would help overcome limited findings of genetic markers associated with meat quality at the selection signals in a previous study. The present study examined genetic associations of marbling score (MS) with intragenic nucleotide variants at selection signals of Korean cattle. A total of 39 092 nucleotide variants of 407 Korean cattle were utilized in the association analysis. A total of 129 variants were selected within newly annotated genes in the bovine genome. Their genetic associations were analyzed using the mixed model with random polygenic effects based on identical-by-state genetic relationships among animals in order to control for spurious associations produced by population structure. Genetic associations of MS were found (P<3.88×10-4) with six intragenic nucleotide variants on bovine autosomes 3 (cache domain containing 1, CACHD1), 5 (like-glycosyltransferase, LARGE), 16 (cell division cycle 42 binding protein kinase alpha, CDC42BPA) and 21 (snurportin 1, SNUPN; protein tyrosine phosphatase, non-receptor type 9, PTPN9; chondroitin sulfate proteoglycan 4, CSPG4). In particular, the genetic associations with CDC42BPA and LARGE were confirmed using an independent data set of Korean cattle. The results implied that allele frequencies of functional variants and their proximity variants have been augmented by directional selection for greater MS and remain selection signals in the bovine genome. Further studies of fine mapping would be useful to incorporate favorable alleles in marker-assisted selection for MS of Korean cattle. PMID:26621608

    People from businesses, public life, public advocacy groups, and experts on international energy met in February 1980 to explore the complex issues of energy policy at a conference entitled Energy Future: Policies and Consequences. The book begins with Crist's overview of current options. David Stockman then examines damaging energy myths and their effects in producing misguided energy policies. Other authors explore the social implications of energy policy, the failure of oil-company management and government to keep energy prices in line with costs, the economic implications of domestic energy policy, international attitudes toward US policy, and the implications of alternative energy sources and conservation. Laffer describes how American presidential economic policies differ from public perceptions. The book concludes with the hope of achieving a future balance of environmental concerns and increased production.

    Antimicrobial agent usage data are essential for focusing efforts to reduce misuse and overuse of antimicrobial agents in food producing animals because these practices may select for resistance in bacteria of animals. Transfer of resistant bacteria from animals to humans can lead to human infection caused by resistant pathogens. Resistant infections can lead to treatment failures, resulting in prolonged or more severe illness. Multiple World Health Organization (WHO) reports have concluded that both antimicrobial resistance and antimicrobial usage should be monitored on the national level. The system for collecting antimicrobial usage data should be clear and transparent to facilitate trend analysis and comparison within and among countries. Therapeutic, prophylactic and growth promotion use should be recorded, along with route of administration and animal species and/or production class treated. The usage data should be compared to resistance data, and the comparison should be made available in a timely manner. In the United States, surveillance of antimicrobial resistance in foodborne bacteria is performed by the National Antimicrobial Resistance Monitoring System (NARMS) for enteric bacteria, however, the United States still lacks a mechanism for collecting antimicrobial usage data. Combined with antimicrobial resistance information from NARMS, antimicrobial usage data will help to direct education efforts and policy decisions, minimizing the risk that people will develop antimicrobial resistant infections as a result of eating food of animal origin. Ultimately mitigation strategies guided by usage data will be more effective in maintaining antimicrobial drugs for appropriate veterinary use and in protecting human health. PMID:16269192

    1985-05-01

    Much of the resistance against Darwin's theory of natural selection has been due to misunderstandings. It is shown that natural selection is not a tautology and that it is a two-step process. The first step, the production of variation, is under the control of chance; the second step, selection proper, is an anti-chance process, but subject to many constraints. The target of selection is the individual as a whole, and many neutral mutations can be retained as hitchhikers of successful genotypes. Sexual selection results from selection for pure reproductive success.

    Coordinated global efforts to prevent and control malaria have been a tour-de-force for public health, but success appears to have reached a plateau in many parts of the world. While this is a multifaceted problem, policy strategies have largely ignored genetic variations in humans as a factor that influences both selection and dosing of antimalarial drugs. This includes attempts to decrease toxicity, increase effectiveness and reduce the development of drug resistance, thereby lowering health care costs. We review the potential hurdles to developing and implementing pharmacogenetic-guided policies at a national or regional scale for the treatment of uncomplicated falciparum malaria. We also consider current knowledge on some component drugs of artemisinin combination therapies and ways to increase our understanding of host genetics, with the goal of guiding policy decisions for drug selection.

    Ivanova, Olena; Dræbel, Tania; Tellier, Siri

    2015-01-01

    Background: Health policies are important instruments for improving population health. However, experience suggests that policies designed for the whole population do not always benefit the most vulnerable. Participation of vulnerable groups in the policy-making process provides an opportunity for them to influence decisions related to their health, and also to exercise their rights. This paper presents the findings from a study that explored how vulnerable groups and principles of human rights are incorporated into national sexual and reproductive health (SRH) policies of 4 selected countries (Spain, Scotland, Republic of Moldova, and Ukraine). It also aimed at discussing the involvement of vulnerable groups in SRH policy development from the perspective of policy-makers. Methods: Literature review, health policy analysis and 5 semi-structured interviews with policy-makers were carried out in this study. Content analysis of SRH policies was performed using the EquiFrame analytical framework. Results: The study revealed that vulnerable groups and core principles of human rights are differently addressed in SRH policies within 4 studied countries. The opinions of policy-makers on the importance of mentioning vulnerable groups in policy documents and the way they ought to be mentioned varied, but they agreed that a clear definition of vulnerability, practical examples, and evidences on health status of these groups have to be included. In addition, different approaches to vulnerable group’s involvement in policy development were identified during the interviews and the range of obstacles to this process was discussed by respondents. Conclusion: Incorporation of vulnerable groups in the SRH policies and their involvement in policy development were found to be important in addressing SRH of these groups and providing an opportunity for them to advocate for equal access to healthcare and exercise their rights. Future research on this topic should include

  11. The role of health education in public policy development.

    PubMed

    Steckler, A; Dawson, L

    1982-01-01

    Health educators should view policy development as a unit of professional practice analogous to the individual, the small group, the community, and the organization. The impact of policy on other units of practice and on people served by health educators is too great and the competition for scarce resources for health and human services is too keen to be disregarded. An increasingly active role in the policy process is, therefore, vital to the profession. Unfortunately, many health educators find an active role strange and lack guidelines for effective policy intervention. This paper attempts to mediate that situation. First a conceptual framework is offered. Operational definitions of important terms are given, including policy, public policy, social policy, health policy, and health education policy. A model of the policy development process is presented, detailing the purpose and dynamics of several steps: establishing problem awareness, setting goals and objectives, selecting a course of action, designing alternative courses of action, analyzing policy, assigning implementation responsibility, implementing, and evaluating. Then five categories of intervention strategies encompassing 16 individual suggested roles ranging from indirect influence to direct political involvement are presented. The categories are: acting as a source of policy information, providing technical assistance, organizing, influencing policymakers, and taking direct political action. PMID:7183668

    2005-01-01

    This paper presents a cyclical theory of U.S. federalism and social policy: Many social policy initiatives are tested and refined at the state level, especially during conservative periods, and later morph into national policies. The paper describes such federalism cycles and offers an interpretation of why and how they occur, focusing on Medicaid. State activism has preserved and expanded Medicaid through policy innovation and resistance to retrenchment, especially in conservative periods, by taking advantage of the flexibility the program provides. I conclude that Medicaid's incremental/partnership approach is appropriate and feasible to build on for a future expansion of health care coverage.

    A discussion of health equity should be intricately examined in policy and practice discourse about the healthcare industry. This article addresses health equity with strategies to institutionalize it through policy implementation. This discourse is relevant to social work because social workers are charged with elucidating conditions that are maniacal and disadvantageous to racial groups, undocumented workers, immigrants and women. Social workers engaged in policy practice should consider how these stakeholders are excluded from health equity, because of the lack of transformative policy implementation that addresses industry practices that encourage disparity and maintain equity. This article hopes to provide a helpful view of health equity.

    On 16 December, NASA became the latest U.S. federal agency to issue a scientific integrity policy. It was issued less than 10 days after the U.S. National Oceanic and Atmospheric Administration (NOAA) issued its policy on the same topic (see "NOAA issues scientific integrity policy," Eos Trans. AGU, 92(50), 467, doi:10.1029/2011EO500004, 2011). The agency policies respond to earlier White House memos on the topic issued in 2009 and 2010. NASA is the fifth federal department or agency that has finalized a scientific integrity policy; the Department of the Interior and the National Science Foundation also have finalized their policies. As Eos went to press, 13 other policies were in near-final draft form, including those from the departments of Agriculture and Energy; the Environmental Protection Agency and the Department of Labor had indicated that they expected to submit their policies to the White House Office of Science and Technology Policy (OSTP) soon, OSTP director John Holdren wrote in a 21 December note on the office's Web site.

    The unavoidability of language makes it critical that language policies appeal to some notion of language neutrality as part of their rationale, in order to assuage concerns that the policies might otherwise be unduly discriminatory. However, the idea of language neutrality is deeply ideological in nature, since it is not only an attempt to treat…

    2013-12-01

    Many current public policy issues have a geoscience component: climate change, natural hazards, energy, and mineral resources to name just a few. In addition, Congress makes decisions that directly affect scientists, such as funding allocations and visa and travel policy. Yet few geoscientists are engaged in the policy-making process. Members of Congress have called on scientists to become more active, including Ph.D. physicist and former-Representative Vernon Ehlers (R-MI). In an address at the 2010 AAAS Forum on Science and Technology Policy, he told scientists, "The gulf between the scientifically minded and those who are not scientifically minded is still tremendous. I think we are keeping far too quiet about what we know and how we would go about solving problems. We have so much to offer this country à solutions to various difficulties." This talk will provide information on avenues for geoscientists to more effectively engage in the public policy arena.

  13. Vested Interests in Addiction Research and Policy Alcohol policies out of context: drinks industry supplanting government role in alcohol policies in sub-Saharan Africa

    PubMed Central

    Bakke, Øystein; Endal, Dag

    2010-01-01

    Background In this paper, we describe an analysis of alcohol policy initiatives sponsored by alcohol producer SABMiller and the International Center on Alcohol Policies, an alcohol industry-funded organization. In a number of sub-Saharan countries these bodies have promoted a ‘partnership’ role with governments to design national alcohol policies. Methodology A comparison was conducted of four draft National Alcohol Policy documents from Lesotho, Malawi, Uganda and Botswana using case study methods. Findings The comparison indicated that the four drafts are almost identical in wording and structure and that they are likely to originate from the same source. Conclusions The processes and the draft policy documents reviewed provide insights into the methods, as well as the strategic and political objectives of the multi-national drinks industry. This initiative reflects the industry's preferred version of a national alcohol policy. The industry policy vision ignores, or chooses selectively from, the international evidence base on alcohol prevention developed by independent alcohol researchers and disregards or minimizes a public health approach to alcohol problems. The policies reviewed maintain a narrow focus on the economic benefits from the trade in alcohol. In terms of alcohol problems (and their remediation) the documents focus upon individual drinkers, ignoring effective environmental interventions. The proposed policies serve the industry's interests at the expense of public health by attempting to enshrine ‘active participation of all levels of the beverage alcohol industry as a key partner in the policy formulation and implementation process’.

  14. Sexual selection.

    PubMed

    Hosken, David J; House, Clarissa M

    2011-01-25

    Sexual selection is a concept that has probably been misunderstood and misrepresented more than any other idea in evolutionary biology, confusion that continues to the present day. We are not entirely sure why this is, but sexual politics seems to have played its role, as does a failure to understand what sexual selection is and why it was initially invoked. While in some ways less intuitive than natural selection, sexual selection is conceptually identical to it, and evolution via either mechanism will occur given sufficient genetic variation. Recent claims that sexual selection theory is fundamentally flawed are simply wrong and ignore an enormous body of evidence that provides a bedrock of support for this major mechanism of organic evolution. In fact it is partly due to this solid foundation that current research has largely shifted from documenting whether or not sexual selection occurs, to addressing more complex evolutionary questions.

    An efficient protocol was standardized for screening of panama wilt resistant Musa paradisiaca cv. Puttabale clones, an endemic cultivar of Karnataka, India. The synergistic effect of 6-benzyleaminopurine (2 to 6 mg/L) and thidiazuron (0.1 to 0.5 mg/L) on MS medium provoked multiple shoot induction from the excised meristem. An average of 30.10 +/- 5.95 shoots was produced per propagule at 4 mg/L 6-benzyleaminopurine and 0.3 mg/L thidiazuron concentrations. Elongation of shoots observed on 5 mg/L BAP augmented medium with a mean length of 8.38 +/- 0.30 shoots per propagule. For screening of disease resistant clones, multiple shoot buds were mutated with 0.4% ethyl-methane-sulfonate and cultured on MS medium supplemented with Fusarium oxysporum f. sp. cubense (FOC) culture filtrate (5-15%). Two month old co-cultivated secondary hardened plants were used for screening of disease resistance against FOC by the determination of biochemical markers such as total phenol, phenylalanine ammonia lyase, oxidative enzymes like peroxidase, polyphenol oxidase, catalase and PR-proteins like chitinase, beta-1-3 glucanase activities. The mutated clones of M. paradisiaca cv. Puttabale cultured on FOC culture filtrate showed significant increase in the levels of biochemical markers as an indicative of acquiring disease resistant characteristics to FOC wilt.

    Shaffer, Howard J; Donato, Anthony N; LaBrie, Richard A; Kidman, Rachel C; LaPlante, Debi A

    2005-01-01

    Background This article reports the first national assessment of patterns of drinking and gambling-related rulemaking on college campuses (e.g., punitive versus recovery oriented). Analyses relating school policies to known school rates of drinking or gambling identified potentially influential policies. These results can inform and encourage the development of guidelines, or "best practices," upon which schools can base future policy. Methods The college policy information was collected from handbooks, Web sites and supplemental materials of 119 scientifically selected colleges included in the fourth (2001) Harvard School of Public Health College Alcohol Study (CAS). A coding instrument of 40 items measured the scope and focus of school alcohol and gambling policies. This instrument included items to measure the presence of specific policies and establish whether the policies were punitive or rehabilitative. A total of 11 coders followed a process of information extraction, coding and arbitration used successfully in other published studies to codify policy information. Results Although all schools had a student alcohol use policy, only 26 schools (22%) had a gambling policy. Punitive and restrictive alcohol policies were most prevalent; recovery-oriented policies were present at fewer than 30% of schools. Certain alcohol and gambling policies had significant relationships with student binge drinking rates. Conclusions The relative lack of college recovery-oriented policies suggests that schools might be overlooking the value of rehabilitative measures in reducing addictive behaviors among students. Since there are few college gambling-related policies, schools might be missing an opportunity to inform students about the dangers of excessive gambling. PMID:15703082

    2015-02-01

    This article examines the role of international institutional actors in China's health policy process. Particular attention is paid to three major international institutional actors: the World Bank, the World Health Organization, and the Global Fund to Fight AIDS, Tuberculosis and Malaria. Through process tracing and comparative case studies, the article looks at how international institutions contribute to policy change in China and seeks to explain different outcomes in the relationship between international institutions and China's health policies. It finds that despite the opaque and exclusive authoritarian structure in China, international institutions play a significant role in the country's domestic health governance. By investing their resources and capabilities selectively and strategically, international institutions can change the preferences of government policy makers, move latent public health issues to the government's agenda, and affect the timing of government action and the content of policy design. Furthermore, the study suggests that different outcomes in the relationship between China's health policies and global health governance can be explained through the seriousness of the externalities China faces.

    The general task was to look beyond the adverse physical impacts and to defining the policy problem. In order for policy actions to be effective, they must address the right policy problems, which will be different from and broader than the physical problems. We will work on defining the policy problems with a view to indicating how practical solutions might be implemented. In particular, public officials need advice on what should be said, and done, and for what purposes. That advice needs to be based on systematic analysis of: (1) the scholarly literature in the social sciences, and related disciplines; (2) the charging content of the policy debate at the center of attention; and (3) how citizens perceive and understand issues related to global change. We will conduct this analysis. Chapter 1 and 2 each reports work on defining the policy problem and analyzing the scholarly literature. Chapters 3 and 4, respectively, address the policy debate and citizen viewpoints in issues related to global change.

    The assessment of health risks of policies is an inevitable, although challenging prerequisite for the inclusion of health considerations in political decision making. The aim of our project was to develop a so far missing methodological guide for the assessment of the complex impact structure of policies. The guide was developed in a consensual way based on experiences gathered during the assessment of specific national policies selected by the partners of an EU project. Methodological considerations were discussed and summarized in workshops and pilot tested on the EU Health Strategy for finalization. The combined tool, which includes a textual guidance and a checklist, follows the top-down approach, that is, it guides the analysis of causal chains from the policy through related health determinants and risk factors to health outcomes. The tool discusses the most important practical issues of assessment by impact level. It emphasises the transparent identification and prioritisation of factors, the consideration of the feasibility of exposure and outcome assessment with special focus on quantification. The developed guide provides useful methodological instructions for the comprehensive assessment of health risks of policies that can be effectively used in the health impact assessment of policy proposals. - Highlights: • Methodological guide for the assessment of health risks of policies is introduced. • The tool is developed based on the experiences from several case studies. • The combined tool consists of a textual guidance and a checklist. • The top-down approach is followed through the levels of the full impact chain. • The guide provides assistance for the health impact assessment of policy proposals.

  11. Managing oil disruptions: issues and policy options. [Monograph

    SciTech Connect

    Webre, P.

    1981-01-01

    The Congressional Budget Office (CBO) prepared the analysis of policy options to help Congress decide whether to extend or expand the Emergency Petroleum Allocation Act of 1973, or whether to let it lapse on September 30, 1981. The central theme is that large disruptions of imported oil can deal the economy a severe blow that reduces output and increases unemployment and inflation. Alternative policies might allow this blow to be offset in different ways, but they cannot eliminate an impact. Some policies better contain the inflationary effects of a disruption, but are less effective in mitigating losses in aggregate production and higher unemployment. For others, the converse is true. Further, the appropriateness of each policy varies with the size and anticipated duration of the import disruption. Congress may wish to consider a portfolio of standby policies as well as the selection of just one. Two appendices offer further policy analyses. 10 references, 3 tables.

  13. Bilingualism: research and policy.

    PubMed

    McCardle, Peggy

    2015-01-01

    Bilingualism, commonplace throughout the world, is not well accepted or supported in many parts of the United States. Education policies and practices regarding bilingualism are often based on myths and attitudes rather than facts, despite scientific evidence on both the disadvantages and advantages of bilingualism. Based on a brief overview of this evidence, I assert that we should embrace more informed policies and practice. Researchers should also work toward new and more complex research approaches to delve more deeply into how the brain organizes and reorganizes with language learning. Despite the continuing need for more research, we know enough to put in place (and study) informed policies and practices that can benefit all children. Now is the time for evidence-based practice, evidence-based policies, and integrative research on bilingualism and education.

    These are intense times at the convergence between science and public policy. Because issues like climate change, stem cell research and environmental protection are being contested in choppy political water, political interests are being deployed to challenge science and researchers, and also to generate pseudo- scientific claims made in the interest of particular policy ends. In a number of cases reported in Science, administration officials have silenced their own employees, or withheld data selectively from draft reports. Added to that challenge to integrity, there is a new statutory environment that adds some complexity of its own. Beginning with the Data Quality Act, more familiarly the "Shelby Amendment," research results with significant economic impacts through regulation are now available through the Freedom of Information Act. Its successor, the Data Quality Act -- which opens a route of challenge to information released by government or gathered by others and used in advice or regulation has exposed scientists not only to having their primary data reanalyzed for the purposes of others, but to charges of research misconduct. These influences have made journal peer review more challenging in several ways, and I will outline some case examples.

    There is little evidence that systematic mental health promotion (MHP) policies exist in the countries of the European Union (EU). In order to explore this, a sample of public health stakeholders in ten European regions was selected. Each region was asked to complete a postal questionnaire about structural indicators of those environmental factors that might have an impact on mental health; stakeholders were also provided with information on MHP concepts and strategies. Subsequently the regions were visited, and stakeholders were interviewed on their MHP policies using an open-ended questionnaire. It was found that there were no existing procedures or plans that could support the hope that systematic MHP policies would be developed in the next years in the EU. Only three of the ten regions had started to develop such policies. An 8-item questionnaire on the framework and process of MHP policy development was developed and used in the present study. This questionnaire may be a useful instrument in future studies on structural indicators of mental health.

    Kidney care and public policy have been linked for 40 years, with various consequences to outcomes. The 1972 Social Security Amendment, Section 2991, expanded Medicare coverage for all modalities of dialysis and transplant services and non-kidney-related care to those with end-stage renal disease (ESRD) regardless of age. This first and only disease-specific entitlement program was a step toward decreasing disparities in access to care. Despite this, disparities in kidney disease outcomes continue as they are based on many factors. Over the last 4 decades, policies have been enacted to understand and improve the delivery of ESRD care. More recent policies include novel shared-risk payment models to ensure quality and decrease costs. This article discusses the impact or potential impact of selected policies on health disparities in advanced chronic kidney disease and ESRD. Although it is too early to know the consequences of newer policies (Affordable Care Act, ESRD Prospective Payment System, Quality Incentive Program, Accountable Care Organizations), their goal of improving access to timely patient-centered appropriate affordable and quality care should lessen the disparity gap. The Nephrology community must leverage this dynamic state of care-delivery model redesign to decrease kidney-related health disparities. PMID:25573513

    The paper summarizes various criteria that can be used in selecting material used in the construction, furnishing, maintenance, and operation of a building. It also summarizes the types of material and product testing that can be especially useful in the selection process. In broad terms, materials in buildings are classified as building materials, furnishings, maintenance materials, and other contents. At any given time, emissions from materials and products in any of these four categories can dominate the impact on indoor air quality (IAQ) in a building. Responsibility for the selection of these materials may be that of the designer, owner, or occupants. Information on IAQ impacts of materials therefore needs to be developed for a wide range of people.

    In 1977 NASA published Shuttle Reimbursement Policies for Civil U.S. Government, DOD and Commercial and Foreign Users. These policies were based on the principle of total cost recovery over a period of time with a fixed flat price for initial period to time to enhance transition. This fixed period was to be followed with annual adjustments thereafter, NASA is establishing a new price for 1986 and beyond. In order to recover costs, that price must be higher than the initial fixed price through FY 1985. NASA intends to remain competitive. Competitive posture includes not only price, but other factors such as assured launch, reliability, and unique services. NASA's pricing policy considers all these factors.

  7. A combined strategy involving Sanger and 454 pyrosequencing increases genomic resources to aid in the management of reproduction, disease control and genetic selection in the turbot (Scophthalmus maximus)

    PubMed Central

    2013-01-01

    Background Genomic resources for plant and animal species that are under exploitation primarily for human consumption are increasingly important, among other things, for understanding physiological processes and for establishing adequate genetic selection programs. Current available techniques for high-throughput sequencing have been implemented in a number of species, including fish, to obtain a proper description of the transcriptome. The objective of this study was to generate a comprehensive transcriptomic database in turbot, a highly priced farmed fish species in Europe, with potential expansion to other areas of the world, for which there are unsolved production bottlenecks, to understand better reproductive- and immune-related functions. This information is essential to implement marker assisted selection programs useful for the turbot industry. Results Expressed sequence tags were generated by Sanger sequencing of cDNA libraries from different immune-related tissues after several parasitic challenges. The resulting database (“Turbot 2 database”) was enlarged with sequences generated from a 454 sequencing run of brain-hypophysis-gonadal axis-derived RNA obtained from turbot at different development stages. The assembly of Sanger and 454 sequences generated 52,427 consensus sequences (“Turbot 3 database”), of which 23,661 were successfully annotated. A total of 1,410 sequences were confirmed to be related to reproduction and key genes involved in sex differentiation and maturation were identified for the first time in turbot (AR, AMH, SRY-related genes, CYP19A, ZPGs, STAR FSHR, etc.). Similarly, 2,241 sequences were related to the immune system and several novel key immune genes were identified (BCL, TRAF, NCK, CD28 and TOLLIP, among others). The number of genes of many relevant reproduction- and immune-related pathways present in the database was 50–90% of the total gene count of each pathway. In addition, 1,237 microsatellites and 7,362 single

    Objectives: To assess the current public participation in-local health policy and its implications through the analysis of policy networks in health center programs. Methods: We examined the decision-making process in sub-health center installations and the implementation process in metabolic syndrome management program cases in two districts (‘gu’s) of Seoul. Participants of the policy network were selected by the snowballing method and completed self-administered questionnaires. Actors, the interactions among actors, and the characteristics of the network were analyzed by Netminer. Results: The results showed that the public is not yet actively participating in the local public health policy processes of decision-making and implementation. In the decision-making process, most of the network actors were in the public sector, while the private sector was a minor actor and participated in only a limited number of issues after the major decisions were made. In the implementation process, the program was led by the health center, while other actors participated passively. Conclusions: Public participation in Korean public health policy is not yet well activated. Preliminary discussions with various stakeholders, including civil society, are needed before making important local public health policy decisions. In addition, efforts to include local institutions and residents in the implementation process with the public officials are necessary to improve the situation. PMID:25475197

    The racial politics of immigration have punctuated national discussions about immigration at different periods in US history, particularly when concerns about losing an American way of life or American population have coincided with concerns about infectious diseases. Nevertheless, the main theme running through American immigration policy is one of inclusion. The United States has historically been a nation reliant on immigrant labor and, accordingly, the most consequential public policies regarding immigration have responded to disease and its economic burdens by seeking to control the behavior of immigrants within our borders rather than excluding immigrants at our borders.

    1980-07-01

    This essay reviews selected aspects of the current status of the study of population policies both for the developed and developing countries. It also endeavors to derive a meaningful research agenda for the study of population policies useful for Japan and other Asian countries. The study begins with the clarification of the study of population policy in relation to the importance of population sciences, population projections, and population problems. It uses 2 studies, 1 by Mauldin and Berelson and the other by the United Nations Population Division as possible prototypes for developing policy studies to evaluate and assess the effects of the population policy upon population processes. 1 conclusion derived from the present study is that the strength of population policy can be enhanced if it is properly combined with the corresponding balanced development of social and economic elements in a society. If population policy is developed without harmonious development in social and economic spheres, then it will not maximize the effects of the government's population policy regardless of how much effort the government expends. Likewise, if there are various subsets of population policy, it is necessary that each subset, whether fiscal, legal, or broadly social, should be coordinated with the others, in order to avoid conflicts or imbalances between them.

    A promising idea for scaling robot learning to more complex tasks is to use elemental behaviors as building blocks to compose more complex behavior. Ideally, such building blocks are used in combination with a learning algorithm that is able to learn to select, adapt, sequence and co-activate the building blocks. While there has been a lot of work on approaches that support one of these requirements, no learning algorithm exists that unifies all these properties in one framework. In this paper we present our work on a unified approach for learning such a modular control architecture. We introduce new policy search algorithms that are based on information-theoretic principles and are able to learn to select, adapt and sequence the building blocks. Furthermore, we developed a new representation for the individual building block that supports co-activation and principled ways for adapting the movement. Finally, we summarize our experiments for learning modular control architectures in simulation and with real robots. PMID:24966830

  15. Abortion and neonaticide: ethics, practice, and policy in four nations.

    PubMed

    Gross, Michael L

    2002-06-01

    Abortion, particularly later-term abortion, and neonaticide, selective non-treatment of newborns, are feasible management strategies for fetuses or newborns diagnosed with severe abnormalities. However, policy varies considerably among developed nations. This article examines abortion and neonatal policy in four nations: Israel, the US, the UK and Denmark. In Israel, late-term abortion is permitted while non-treatment of newborns is prohibited. In the US, on the other hand, later-term abortion is severely restricted, while treatment to newborns may be withdrawn. Policy in the UK and Denmark bridges some of these gaps with liberal abortion and neonatal policy. Disparate policy within and between nations creates practical and ethical difficulties. Practice diverges from policy as many practitioners find it difficult to adhere to official policy. Ethically, it is difficult to entirely justify perinatal policy in these nations. In each nation, there are elements of ethically sound policy, while other aspects cannot be defended. Ethical policy hinges on two underlying normative issues: the question of fetal/newborn status and the morality of killing and letting die. While each issue has been the subject of extensive debate, there are firm ethical norms that should serve as the basis for coherent and consistent perinatal policy. These include 1) a grant of full moral and legal status to the newborn but only partial moral and legal status to the late-term fetus 2) a general prohibition against feticide unless to save the life of the mother or prevent the birth of a fetus facing certain death or severe pain or suffering and 3) a general endorsement of neonaticide subject to a parent's assessment of the newborn's interest broadly defined to consider physical harm as well as social, psychological and or financial harm to related third parties. Policies in each of the nations surveyed diverging from these norms should be the subject of public discourse and, where possible

    In Appalachian areas, strong tobacco control policies are not in place, so residents are not adequately protected from secondhand smoke exposure. This area is predominantly rural, and residents experience a high burden of tobacco-related illnesses. There has been limited examination of elements that hinder smoke-free policy adoption in these vulnerable communities. Key informant interviews were conducted with individuals identified as being knowledgeable about local tobacco control policy activities within a random selection of Appalachian communities within 6 states with (n = 15) and without (n = 12) local smoke-free policies. Five key themes emerged from the qualitative interviews: (1) opposition to tobacco control, (2) need for local involvement, (3) role of community coalitions, (4) leveraging outside advocates, and (5) working with decision makers. In Appalachian communities, the local context and locally-based coalitions were critical to promote the adoption of smoke-free policies.

  17. Regulatory policy and abortion clinics: implications for planning.

    PubMed

    Kay, B J; Neal, J R

    1978-01-01

    The practicalities of formulating regulatory policy associated with elective abortion often place public health officials at the center of political controversy. Resulting conflicts can inhibit a rational consideration of long-term objectives in implementing a national policy which assures legal accessibility to all who would select abortion as an alternative to term birth. Regulation which uses primarily structural criteria for monitoring and evaluating services tends to de-emphasize the importanc of contraceptive counseling as a component of abortion services. Our process/outcome evaluation of abortion clinics located in Chicago suggests that contraceptive counseling provided at the time of the abortion procedure has a potential long-term impact in terms of reducing the need for elective abortion. We suggest that regulation policy should include process and outcome criteria which support the eventual reduction in need for abortion as a long-range policy goal and suggest key issues for consideration when such a policy is formulated.

    PubMed

    Wagner, Paul

    2014-04-01

    A majority of approximate dynamic programming approaches to the reinforcement learning problem can be categorized into greedy value function methods and value-based policy gradient methods. The former approach, although fast, is well known to be susceptible to the policy oscillation phenomenon. We take a fresh view to this phenomenon by casting, within the context of non-optimistic policy iteration, a considerable subset of the former approach as a limiting special case of the latter. We explain the phenomenon in terms of this view and illustrate the underlying mechanism with artificial examples. We also use it to derive the constrained natural actor-critic algorithm that can interpolate between the aforementioned approaches. In addition, it has been suggested in the literature that the oscillation phenomenon might be subtly connected to the grossly suboptimal performance in the Tetris benchmark problem of all attempted approximate dynamic programming methods. Based on empirical findings, we offer a hypothesis that might explain the inferior performance levels and the associated policy degradation phenomenon, and which would partially support the suggested connection. Finally, we report scores in the Tetris problem that improve on existing dynamic programming based results by an order of magnitude. PMID:24491826

    Astronomy is an unusual science in that almost all of what we study can only be passively observed. We enjoy tremendous public support for our research and education, both domestically and abroad. Our discoveries in cosmology and exoplanets have captured world-wide attention, as have stunning images from the Great Observatories of NASA, and ground based telescopes. Despite the passive nature of our science, it touches humanity profoundly. There are groups of amateur astronomers in every conceivable country who meet to look at the sky. Almost one billion people from 150 countries participated in The International Year of Astronomy 2009. No other science reaches humanity as ours does. In a recent poll, it was found that the among all the things the US does abroad, US science is seen by the world as our most positive face. We as astronomers can use this good will to affect positive changes in the world through public policy. I would like to explore how astronomy has impacted public policy, especially foreign policy, and what more we can do in the future. I also hope to encourage astronomers that a career path into public policy is an excellent use of a Ph.D. in astronomy.

  10. Population policies and development.

    PubMed

    Stamper, B M

    1984-01-01

    This article critically examines 4 conceptual frameworks for Third World population policies: the family planning approach, beyond family planning measures, the development hypothesis and transition theory, and the distributive hypothesis and fertility. Although family planning is a basic human right and can lead to lower levels of population and improved maternal-child health, this approach alone does not always have a meaningful demographic impact. If high fertility is economically rational from the family viewpoint, the demand for family planning services will remain marginal. Other policies seek to go beyond the family planning approach and to directly influence the demand for reproductive control through provision of old age support, monetary incentives for reduced fertility or stringent and coercive measures. However, such policies can have adverse distributional effects and directly penalize the children of large families. The demographic transition theory lacks a measurable and specifiable causation mechanism, giving it little predictive value. It may be that economic growth increases fertility in the short run and reduces fertility only over the long run through indirect effects. The key issue is how the rate of growth is distributed across the population. The development and demographic transition hypothesis focuses mainly on aggregate economic and social measures rather than on their underlying distributions. The distributive hypothesis implies policies that promote a greater level of investment in human capital, with a wide distributional emphasis. Diffused investment in human capital is believed to indirectly influence the desire to control fertility. It is concluded that all 4 conceptual frameworks for analyzing fertility-related policies for the Third World are inadequate or seriously flawed. They are not pragmatic, do not identify or assign weights to the crucial causal variables, fail to specify thresholds or critical minimum levels, discount

  11. Fine mapping of the clubroot resistance gene CRb and development of a useful selectable marker in Brassica rapa.

    In Chinese cabbage (Brassica rapa), the clubroot resistance (CR) gene CRb is effective against Plasmodiophora brassicae isolate No. 14, which is classified as pathotype group 3. Although markers linked to CRb have been reported, an accurate position in the genome and the gene structure are unknown. To determine the genomic location and estimate the structure of CRb, we developed 28 markers (average distance, 20.4 kb) around CRb and constructed a high-density partial map. The precise position of CRb was determined by using a population of 2,032 F2 plants generated by selfing B. rapa 'CR Shinki.' We determined that CRb is located in the 140-kb genomic region between markers KB59N07 and B1005 and found candidate resistance genes. Among other CR genes on chromosome R3, a genotype of CRa closest marker clearly matched those of CRb and Crr3 did not confer resistance to isolate No. 14. Based on the genotypes of 11 markers developed near CRb and resistance to isolate No. 14, 82 of 108 cultivars showed a strong correlation between genotypes and phenotypes. The results of this study will be useful for isolating CRb and breeding cultivars with resistance to pathotype group 3 by introducing CRb into susceptible cultivars through marker-assisted selection.

    Fusarium crown and root rot is a severe fungal disease of tomato caused by Fusarium oxysporum f. sp. radicis-lycopersici (FORL). In this study, the genomic location of the FORL-resistance locus was determined using a set of molecular markers on chromosome 9 and an F2 population derived from FORL-resistant inbred 'AV107-4' (Solanum lycopersicum) × susceptible 'L3708' (Solanum pimpinellifolium). Bioassay performed using Korean FORL strain KACC 40031 showed single dominant inheritance of FORL resistance in the F2 population. In all, 13 polymerase chain reaction-based markers encompassing approximately 3.6-72.0 Mb of chromosome 9 were developed based on the Tomato-EXPEN 2000 map and SolCAP Tomato single nucleotide polymorphism array analysis. These markers were genotyped on 345 F2 plants, and the FORL-resistance locus was found to be present on a pericentromeric region of suppressed chromosomal recombination in chromosome 9. The location of the FORL-resistance locus was further confirmed by testing these markers against diverse commercial tomato and stock cultivars resistant to FORL. A restriction fragment length polymorphism marker, PNU-D4, located at approximately 6.1 Mb of chromosome 9 showed the highest match with the resistance locus and was used for conducting high-resolution melting analysis for marker-assisted selection of FORL resistance.

  19. A new era in Australian migration policy.

    PubMed

    Birrell, R

    1984-01-01

    The discussion traces the evolution of Australian migration policy since 1975, arguing that the primary factor shaping policy has been interparty competition for influence within Australia's ethnic communities. Since late 1975 when the Liberal/National Country Party (LibNCP) Conservative Government returned to power, Australian immigration policy has moved in different directions from the previous post World War II experience. The demographic implications have been profound. In 1975 the LibNCP government returned to office committed to restoring an active migration program. By 1980-81 it had largely succeeded in this numerical goal. Australia's migration growth rate at .82% of the total population exceeded almost all other Western society. What was new, in comparison to previous policy, was the migrant selection system and source countries. By the time the government lost office in March 1983, family reunion had become the major migration program souce and Asia was rapidly becoming the dominant place of migrant origin. This emphasis on family reunion was not intended by government immigration planners but was a product of domestic political change and resultant new influences over migration policy. As to the increasing Asian component, it has mainly been an unintended consequence of the expansion in the family reunion program. Although the liberalization of family reunion eligibility has largely been designed to appease the major Southern European ethnic communities, few applications have been forthcoming from these countries. Asian applicants have been numerous. Labor government policy since March 1983 has shown remarkable continuity with that of the LibNCP both in its selection system and in the size of the migrant intake. The motivation for the commitment to immigration derived first from longstanding traditions within the Australian business community that Australia's economic growth and dynamism depended on rapid population growth.

    Dental diseases are a significant public health menace having a substantial impact on the quality of life which in turn affects the daily performance and general life satisfaction. There is a vast difference in health status including the oral health between urban and rural population of India and in other developing countries. The existing situation demands the formulation and implementation of National Oral Health Policy in India in order to expand the oral health care to make it more affordable, and reachable. An extensive literature search was conducted using various search engines in order to include relevant information in the review. Number of keywords and their combinations were used in order to extract appropriate data. Finally 24 out of 35 articles were selected upon detailed reading. The present paper focusses on some of the important subjects that can be considered while formulation of a National Oral Health Policy for the benefits of both the dental profession and community as a whole. There is a need of dental health planners and policy makers that have relevant qualifications and training in public health dentistry to understand the unique needs and resources for the development of an effective oral health policy. Professional dental organizations can also support government programs to provide basic oral health needs of extensive underserved population of this country. PMID:27144077

    2002-01-01

    There is a growing debate about the future direction of migration policy in Europe. After nearly 30 years of pursuing restrictive immigration and asylum policies, many European Union (EU) governments are beginning to re-assess their migration policies and to call for a new approach. For the first time in many years, several EU governments have begun to talk again about the benefits of labour migration and, even more significantly, have even begun to take action to recruit more migrants, especially skilled workers. This paper looks at the background to current calls for a new approach to migration in Europe and public reaction to these new initiatives. It first describes recent trends in migration in Europe and then briefly considers the demographic case for more migration. This is followed by a brief outline of some of the measures being considered by European governments to promote selective labour migration. The remainder of the paper is devoted to a discussion of some of the implications of this change in policy, focusing on two main issues: the likely consequences for sending countries, and the implications for the fight against the smuggling and trafficking of people.

    Parthenocarpy, the ability to set fruits without pollination, is a useful trait for setting fruit under unfavorable conditions. To identify the loci controlling parthenocarpy in eggplant (Solanum melongena L.), we constructed linkage maps by using co-dominant simple sequence repeat and single nucleotide polymorphism markers in F(2) populations derived from intraspecific crosses between two non-parthenocarpic lines (LS1934 and Nakate-Shinkuro) and a parthenocarpic line (AE-P03). Total map distances were 1,414.6 cM (ALF2: LS1934 x AE-P03) and 1,153.8 cM (NAF2: Nakate-Shinkuro x AE-P03), respectively. Quantitative trait locus (QTL) analyses revealed two QTLs on chromosomes 3 and 8, which we denoted as Controlling parthenocarpy3.1 (Cop3.1) and Cop8.1, respectively. The percentage of phenotypic variance explained (PVE) of Cop3.1 was 6.3% in ALF2 (LOD = 4.2) and 10.6% in NAF2 (LOD = 3.0). The PVE of Cop8.1 was 45.7% in ALF2 (LOD = 23.8) and 29.7% in NAF2 (LOD = 7.9). Using a population of backcross inbred lines, we confirmed the effect of Cop8.1, but there was no evidence to support the contribution of Cop3.1. We need to verify the effect of Cop3.1 under various temperature conditions. In addition, we clarified the effectiveness of selective SSR markers, emf21H22 and emh11J10, mapped on each side of Cop8.1 in other F(2) populations derived from various parental combinations. This is the first report concerning QTL analysis of parthenocarpy in eggplant using molecular markers. It will be useful in marker-assisted selection and in revealing the genomic mechanism underlying parthenocarpy in eggplant. PMID:22301906

    In this paper, we analyze the role that early years policy might play in narrowing educational attainment gaps. We begin by examining gaps in school readiness between low-, middle-, and high-income children, drawing on data from new large and nationally representative birth cohort studies in the US and UK. We find that sizable income-related gaps in school readiness are present in both countries before children enter school and then decompose these gaps to identify the factors that account for the poorer scores of low-income children. We then consider what role early years policy could play in tackling these gaps, drawing on the best available evidence to identify promising programs. PMID:21731827

    The paper discusses the articulation among epidemiological information systems, scientific production and men's health policies. Three secondary sources were used: data from the Ministry of Health (Mortality and Hospital Information Systems, Surveillance of Protection and Risk Factors for Chronic Diseases through Telephone Survey), papers published in SciELO, and documents of the Ministry of Health regarding men's health. The results indicate that, in terms of morbidity and mortality, men are more exposed to risks than women. In the scientific production, studies focus predominantly on injuries and diseases that affect exclusively the male population, to the detriment of other health-related aspects. Legal documents highlight the epidemiological panorama of male morbidity and mortality and the policy-making methodology. Researchers need to expand the use of data from the epidemiological information systems of the Ministry of Health and to incorporate the gender relational perspective critically.

    It has been part of the role of medical organizations in Western nations to develop position statements on various sociopolitical issues. Both the American Psychiatric Association and the American Medical Association have established position statements related to social policy, including capital punishment. In 2001, AAPL endorsed a moratorium on capital punishment. Recent calls for AAPL to endorse a recommendation to abolish the death penalty have produced further discussion and a diversity of opinion. The absence of a clear process to develop policy within AAPL complicates both the nature and the resolution of the discussions. Three questions are posed that will help AAPL shape this debate: (1) Do we have anything to contribute? (2) Is there a position consistent with our values? (3) Would a position promote or harm the goals and mandate of the organization?

    Do you really need to have a policy and procedure in the office? Frequently they are seen sitting on the shelf, collecting dust. The answer is yes for a number of very important reasons. A policy and procedure manual is a tool to set guidelines and expectations on the basis of the mission and vision of the office. A well-written manual is a powerful training tool for new staff so they can get a feel for the office culture. Furthermore, it is a provincial or state legislative requirement that can reduce management's concern about potential legal issues or problems. If an office does not have a manual to set guidelines, the employees may be forced to make their own decisions to solve problems, which can often result in confusion, inconsistencies, and mistakes.

    From the late nineteenth century through 1974, France permitted immigration to furnish workers and to compensate for the low level of fertility. Intense immigration from North Africa, the economic crisis of the 1970s, and other factors led to policy changes in 1974. French immigration policy since 1974 has fluctuated between guaranteeing foreigners equal rights regardless of their religion, race, culture, or national origin, and attempting to differentiate among immigrants depending on their degree of assimilability to French culture. From 1974 to 1988, France had five different policies regarding whether to permit new immigration and what to do about illegal immigrants. In July 1984, the four major political parties unanimously supported a measure in Parliament that definitively guaranteed the stay in France of legal immigrants, whose assimilation thus assumed priority. Aid for return to the homeland was no longer to be widely offered, and immigration of unskilled workers was to be terminated except for those originating in European Community countries. Major changes of government in 1988 and 1993 affected only the modalities of applying these principles. The number of immigrants has fluctuated since 1974. Unskilled workers, the only category whose entrance was specifically controlled by the 1984 measures, have declined from 174,000 in 1970 to 25,000 in the early 1990s. The number of requests for political asylum declined from 60,000 in 1989 to 27,000 in 1993, and in 1991, 15,467 persons were granted refugee status. The number of immigrants of all types permitted to remain in France declined from 250,000 or 3000 per year in the early 1970s to around 110,000 at present. Although the decline is significant, it appears insufficient to the government in power since 1993. Although migratory flows are often explained as the product of imbalance in the labor market or in demographic growth, the French experience suggests that government policies, both in the sending and

    Apart from the journals they produce, scientific societies play an important role in communicating scientific findings and norms to the broader society. The American Association for the Advancement of Science (AAAS) includes among its goals to promote and defend the integrity of science and its use; provide a voice for science on societal issues; promote the responsible use of science in public policy; and increase public engagement with science and technology. AAAS websites and programs, including Communicating Science (www.aaas.org/communicatingscience), Working with Congress (http://www.aaas.org/spp/cstc/wwc/book.htm) and ScienceCareers.org (http://sciencecareers.sciencemag.org), provide tools for scientists to become more directly engaged in effectively communicating their findings and involved in the policy process. Education programs work to build the next generation of scientists and a science-literate public. To bridge the current communication gap between scientists, the public and policymakers, AAAS, like other scientific societies, maintains policy and outreach programs with limited budgets and staff. AAAS works to engage policymakers and provide scientific underpinning to key issues through congressional briefings, meetings, policy briefs, and media outreach. AAAS responds to challenges to accepted scientific findings and processes through op-eds, letters to government officials, resolutions, and Board statements. Some of these initiatives occur on a local level in partnership with local civic leaders, whose endorsement makes them more powerful. On a national scale, they assure that the voice of science is included in the debate. The changing media landscape presents opportunities and challenges for future AAAS endeavors.

  8. Manufacturers' support policies.

    1992-09-01

    Choosing an effective plan for supporting a medical device is critical to its safe use, cost-effectiveness, and longevity. Hospitals can choose from a variety of support providers, including manufacturers, third-party service vendors, or hospital clinical engineering (CE) departments. However, if the hospital plans to use a third-party service vendor or its own CE department to provide support, the manufacturer's cooperation or assistance will still be needed to implement the support plan effectively. Over the years, ECRI has received many comments from hospitals about the way in which manufacturers respond to their equipment support needs. We have learned that some manufacturers are not willing to assist third-party service vendors or in-house service programs or do not always deliver the support they promise. Also, hospitals do not always consider their support needs before purchase, when they have the most leverage to negotiate flexible support arrangements. To help foster better equipment support and customer satisfaction, we polled manufacturers that have participated in recent Health Devices Evaluations to obtain detailed information about their policies toward manufacturers' contract, third-party, and in-house support. Ready access to this information will help hospitals evaluate whether manufacturers' support policies will meet their needs, and it will allow them to minimize problems by working with the manufacturer to negotiate optimal support arrangements during the purchase process. In this article, we briefly discuss the factors to consider when evaluating support alternatives and manufacturers' support policies. We also present the questions posed to each manufacturer on our Manufacturers' Support Policies Questionnaire, along with a summary of the responses that we received for each question.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1428903

    Peru's 1985 Population Policy Law states as its second objective that individuals and couples should be well informed and provided with the education and health services that will assist them in making responsible decisions about the number and spacing of their children. Thus, the law establishes a firm basis for IEC programs. With regard to population education, the purpose of the law is to create awareness through all educational channels of the reciprocal influence of population dynamics and socioeconomic development and to promote positive attitudes toward small family size. The law promotes the use of the communications media to educate and inform about population issues. The National Population Council, which coordinates and supervises the IEC activities of public sector agencies, has issued publications and audiovisual materials, conducted meetings with government officials and opinion leaders, and promoted awareness of population policy as a key part of development planning. In 1984, the Council organized the First National Seminar on Communication and Population to review activities, set the basis for intersectoral coordination, unify criteria, and review population policy concepts and language. The Ministry of Health carries out IEC activities as part of its family planning services program. In addition, the Ministry of Education has organized a national population education program that aims to revise school curricula to include a greater emphasis on population dynamics and family life education. The activities of a number of private institutions complement the IEC work public sector organizations. PMID:12341769

    This policy statement reviews important trends and other factors that affect the pediatrician workforce and the provision of pediatric health care, including changes in the pediatric patient population, pediatrician workforce, and nature of pediatric practice. The effect of these changes on pediatricians and the demand for pediatric care are discussed. The American Academy of Pediatrics (AAP) concludes that there is currently a shortage of pediatric medical subspecialists in many fields, as well as a shortage of pediatric surgical specialists. In addition, the AAP believes that the current distribution of primary care pediatricians is inadequate to meet the needs of children living in rural and other underserved areas, and more primary care pediatricians will be needed in the future because of the increasing number of children who have significant chronic health problems, changes in physician work hours, and implementation of current health reform efforts that seek to improve access to comprehensive patient- and family-centered care for all children in a medical home. The AAP is committed to being an active participant in physician workforce policy development with both professional organizations and governmental bodies to ensure a pediatric perspective on health care workforce issues. The overall purpose of this statement is to summarize policy recommendations and serve as a resource for the AAP and other stakeholders as they address pediatrician workforce issues that ultimately influence the quality of pediatric health care provided to children in the United States.

    At the nanoscale measures can move from a mass-scale analogue calibration to counters of discrete units. The shift redefines the possible levels of control that can be achieved in a system if adequate selectivity can be imposed. As an example as ionic substances pass through nanoscale pores, the quantity of ions is low enough that the pore can contain either negative or positive ions. Yet precise control over this selectivity still raises difficulties. In this issue researchers address the challenge of how to regulate the ionic selectivity of negative and positive charges with the use of an external charge. The approach may be useful for controlling the behaviour, properties and chemical composition of liquids and has possible technical applications for nanofluidic field effect transistors [1]. Selectivity is a critical advantage in the administration of drugs. Nanoparticles functionalized with targeting moieties can allow delivery of anti-cancer drugs to tumour cells, whilst avoiding healthy cells and hence reducing some of the debilitating side effects of cancer treatments [2]. Researchers in Belarus and the US developed a new theranostic approach—combining therapy and diagnosis—to support the evident benefits of cellular selectivity that can be achieved when nanoparticles are applied in medicine [3]. Their process uses nanobubbles of photothermal vapour, referred to as plasmonic nanobubbles, generated by plasmonic excitations in gold nanoparticles conjugated to diagnosis-specific antibodies. The intracellular plasmonic nanobubbles are controlled by laser fluence so that the response can be tuned in individual living cells. Lower fluence allows non-invasive high-sensitive imaging for diagnosis and higher fluence can disrupt the cellular membrane for treatments. The selective response of carbon nanotubes to different gases has leant them to be used within various different types of sensors, as summarized in a review by researchers at the University of

    Public health professionals have an opportunity to refocus national attention on food and nutrition policy, within a sustainability agenda. A broadly based national Food and Nutrition Policy was developed in 1992. However, its implementation has been selective and primarily based within the health sector. Other major policy areas, for example; industry, agriculture and trade, have dominated Australian nutrition and health policy. A broad, whole-of-government commitment to a comprehensive food and nutrition policy that engages with the community is required to achieve outcomes in terms of public health, a sustainable environment and viable food production for future generations.

  15. Genome-wide response to selection and genetic basis of cold tolerance in rice (Oryza sativa L.)

    PubMed Central

    2014-01-01

    Background Cold stress is an important factor limiting rice yield in many areas of high latitude and altitude. Considerable efforts have been taken to genetically dissect cold tolerance (CT) in rice using DNA markers. Because of possible epistasis and gene × environment interactions associated with identified quantitative trait loci, the results of these genetic studies have unfortunately not been directly applicable to marker-assisted selection for improved rice CT. In this study, we demonstrated the utility of a selective introgression strategy for simultaneous improvement and genetic dissection of rice seedling CT. Results A set of japonica introgression lines (ILs) with significantly improved seedling CT were developed from four backcross populations based on two rounds of selection. Genetic characterization of these cold-tolerant ILs revealed two important aspects of genome-wide responses to strong phenotypic selection for rice CT: (1) significant over-introgression of donor alleles at 57 loci in 29 functional genetic units (FGUs) across the rice genome and (2) pronounced non-random associations between or among alleles at many unlinked CT loci. Linkage disequilibrium analyses of the detected CT loci allowed us to construct putative genetic networks (multi-locus structures) underlying the seedling CT of rice. Each network consisted of a single FGU, with high introgression as the putative regulator plus two to three groups of highly associated downstream FGUs. A bioinformatics search of rice genomic regions harboring these putative regulators identified a small set of candidate regulatory genes that are known to be involved in plant stress response. Conclusions Our results suggest that CT in rice is controlled by multiple pathways. Genetic complementarity between parental-derived functional alleles at many loci within a given pathway provides an appropriate explanation for the commonly observed hidden diversity and transgressive segregation of CT and other

    This perspective is an ethical brief overview and examination of “wellness” policies in the modern workplace using practical examples and a general application of utilitarianism. Many employers are implementing policies that provide incentives to employees who lead a “healthy” lifestyle. The authors address how these policies could adversely affect “non-healthy” employees. There are a wide variety of ethical issues that impact wellness policies and practices in the workplace. The authors conclude that wellness programs can be ethical, while also providing a general reflective analysis of healthcare challenges in order to reflect on the externalities associated with such policies in the workplace.

    Policies can be powerful tools for prevention given their potential to affect conditions that can improve population-level health. Given the dearth of empirical research on policies' impacts on child maltreatment, this article (a) identifies 37 state policies that might have impacts on the social determinants of child maltreatment; (b) identifies available data sources documenting the implementation of 31 policies; and (c) utilizes the available data to explore effects of 11 policies (selected because they had little missing data) on child maltreatment rates. These include two policies aimed at reducing poverty, two temporary assistance to needy families policies, two policies aimed at increasing access to child care, three policies aimed at increasing access to high quality pre-K, and three policies aimed at increasing access to health care. Multi-level regression analyses between within-state trends of child maltreatment investigation rates and these 11 policies, controlling for states' childhood poverty, adults without a high school diploma, unemployment, child burden, and race/ethnicity, identified two that were significantly associated with decreased child maltreatment rates: lack of waitlists to access subsidized child care and policies that facilitate continuity of child health care. These findings are correlational and are limited by the quality and availability of the data. Future research might focus on a reduced number of states that have good quality administrative data or population-based survey data on child maltreatment or reasonable proxies for child maltreatment and where data on the actual implementation of specific policies of interest can be documented.
