    Around the globe, leaders of governments and other stakeholder institutions enter 2017 facing a set of difficult and increasingly urgent questions:With fiscal space limited, interest rates near zero, and demographic trends unfavorable in many countries, does the world economy face a protracted period of relatively low growth? Will macroeconomics and demography determine the world economy's destiny for the foreseeable future?Can rising in-country inequality be satisfactorily redressed within the prevailing liberal international economic order? Can those who argue that modern capitalist economies face inherent limitations in this regard – that their internal "income distribution system" is broken and likely beyond repair – be proven wrong?As technological disruption accelerates in the Fourth Industrial Revolution, how can societies organize themselves better to respond to the potential employment and other distributional effects? Are expanded transfer payments the only or primary solution, or can market mechanisms be developed to widen social participation in new forms of economic value-creation?These questions beg the more fundamental one of whether a secular correction is required in the existing economic growth model in order to counteract secular stagnation and dispersion (chronic low growth and rising inequality). Does the mental map of how policymakers conceptualize and enable national economic performance need to be redrawn? Is there a structural way, beyond the temporary monetary and fiscal measures of recent years, to cut the Gordian knot of slow growth and rising inequality, to turn the current vicious cycle of stagnation and dispersion into a virtuous one in which greater social inclusion and stronger and more sustainable growth reinforce each other?This is precisely what government, business, and other leaders from every region have been calling for. Over the past several years, a worldwide consensus has emerged on the need for a more inclusive growth and development model; however, this consensus is mainly directional. Inclusive growth remains more a discussion topic than an action agenda. This Report seeks to help countries and the wider international community practice inclusive growth and development by offering a new policy framework and corresponding set of policy and performance indicators for this purpose

    Assessing the Cost of Best Management Practices in Arkansas

    A geographic information system (GIS) is a set of powerful, computer-based, analytical algorithms for solving spatial data problems. Recently, due to increases in memory size, computing speed, and programming advances, personal computers have been used in spatial analysis problems. This study reports the benefits of using a PC-based GIS system to solve a common, but complicated problem in forest management: assignment of harvesting areas with harvesting exclusion zones. Two stands each from the USDA Crossett Experimental Forest, the University of Arkansas Forest, and the Ouachita National Forest (total six) were analyzed to determine the changes due to following best management practices (BMPs) and by excluding sensitive areas from harvesting activity with stream-side management zones (SMZs). A onetime loss land, averaging seven percent of the forest land, was taken out of production due to the implementation of SMZs. Benefit cost ratios of harvestable timber value to harvesting cost decreased with the imposition of SMZs, but the judicious use of portable bridging to span SMZs at critical locations mitigated losses significantly

    Investigation into the effect of mannan-rich fraction supplementation on the metagenome of broiler chickens

    Antibiotic resistance is regarded as one of the most serious threats to human health worldwide. The rapid increase in resistance rates has been attributed to the extensive use of antibiotics since they became commercially available. The use of antibiotics as growth promotors has been banned in numerous regions for this reason. Mannan-rich fraction (MRF) has been reported to show similar growth-promoting effects to antibiotics. We investigated the effect of MRF on the microbial community, resistome and metabolic pathways within the caecum of commercial broilers at two different timepoints within the growth of the broiler, day 27 and day 34. The data indicated an overall increase in health and economic gain for the producer with the addition of MRF to the diet of the broilers. The only significant difference across the microbial composition of the samples was in the richness of the microbial communities across all samples. While all samples harboured resistance genes conferring resistance to the same classes of antibiotics, there was significant variation in the antimicrobial resistance gene richness across time and treatment and across combinations of time and treatment. The taxa with positive correlation comprised Bacilli and Clostridia. The negative correlation taxa were also dominated by Bacilli, specifically the Streptococcus genera. The KEGG-pathway analysis identified an age-related change in the metabolism pathway abundances of the caecal microflora. We suggest that the MRF-related increases in health and weight gain in the broilers may be associated with changes in the metabolism of the microbiomes rather than the microbial composition. The resistome variations across samples were correlated with specific genera. These data may be used to further enhance the development of feed supplements to reduce the presence of antibiotic resistance genes (ARGs) within poultry. While the ARGs of greatest concern to human or animal health were not detected in this study, it has identified the potential to reduce the presence of ARGs by the increase in specific genera

    Instanton Moduli for T**3xR

    We review the specific problems that arise when studying instantons on a torus. We discuss how the Nahm transformation shows that no exact charge one instanton on T**4 can exist. However, taking one of the directions (the time) to infinity, it can be shown that vacuum to vacuum tunnelling solutions exist. A precise description of the moduli space for T**3xR, studied numerically using lattice techniques, remains an interesting open problem. New is an explicit application of the Nahm transformation to (anti-)selfdual constant curvature solutions on T**4 and a discussion of its properties relevant to instantons on T**3xR.Comment: 12p with 3 figs, uufiles -gz format.

    ADHM Construction of Instantons on the Torus

    Get PDF
    We apply the ADHM instanton construction to SU(2) gauge theory on T^n x R^(4-n)for n=1,2,3,4. To do this we regard instantons on T^n x R^(4-n) as periodic (modulo gauge transformations) instantons on R^4. Since the R^4 topological charge of such instantons is infinite the ADHM algebra takes place on an infinite dimensional linear space. The ADHM matrix M is related to a Weyl operator (with a self-dual background) on the dual torus tilde T^n. We construct the Weyl operator corresponding to the one-instantons on T^n x R^(4-n). In order to derive the self-dual potential on T^n x R^(4-n) it is necessary to solve a specific Weyl equation. This is a variant of the Nahm transformation. In the case n=2 (i.e. T^2 x R^2) we essentially have an Aharonov Bohm problem on tilde T^2. In the one-instanton sector we find that the scale parameter, lambda, is bounded above, (lambda)^2 tv<4 pi, tv being the volume of the dual torus tilde T^2.Comment: 35 pages, LATeX. New section on Nahm transform included, presentation improved, reference added, to appear in Nuclear Physics

    Pleasure and meaningful discourse: an overview of research issues

    Get PDF
    The concept of pleasure has emerged as a multi-faceted social and cultural phenomenon in studies of media audiences since the 1980s. In these studies different forms of pleasure have been identified as explaining audience activity and commitment. In the diverse studies pleasure has emerged as a multi-faceted social and cultural concept that needs to be contextualized carefully. Genre and genre variations, class, gender, (sub-)cultural identity and generation all seem to be instrumental in determining the kind and variety of pleasures experienced in the act of viewing. This body of research has undoubtedly contributed to a better understanding of the complexity of audience activities, but it is exactly the diversity of the concept that is puzzling and poses a challenge to its further use. If pleasure is maintained as a key concept in audience analysis that holds much explanatory power, it needs a stronger theoretical foundation. The article maps the ways in which the concept of pleasure has been used by cultural theorists, who have paved the way for its application in reception analysis, and it goes on to explore the ways in which the concept has been used in empirical studies. Central to our discussion is the division between the ‘public knowledge’ and the ‘popular culture’ projects in reception analysis which, we argue, have major implications for the way in which pleasure has come to be understood as divorced from politics, power and ideology. Finally, we suggest ways of bridging the gap between these two projects in an effort to link pleasure to the concepts of hegemony and ideology

    Targeting smoking cessation to high prevalence communities: outcomes from a pilot intervention for gay men

    Get PDF
    BACKGROUND: Cigarette smoking prevalence among gay men is twice that of population levels. A pilot community-level intervention was developed and evaluated aiming to meet UK Government cessation and cancer prevention targets. METHODS: Four 7-week withdrawal-oriented treatment groups combined nicotine replacement therapy with peer support. Self-report and carbon monoxide register data were collected at baseline and 7 weeks. N = 98 gay men were recruited through community newspapers and organisations in London UK. RESULTS: At 7 weeks, n = 44 (76%) were confirmed as quit using standard UK Government National Health Service monitoring forms. In multivariate analysis the single significant baseline variable associated with cessation was previous number of attempts at quitting (OR 1.48, p = 0.04). CONCLUSIONS: This tailored community-level intervention successfully recruited a high-prevalence group, and the outcome data compares very favourably to national monitoring data (which reports an average of 53% success). Implications for national targeted services are considered
