Insight Into

Abstract Background Noni (Morinda citrifolia Linn.) is a tropical tree that bears climacteric fruit. Previous observations and research have shown that the second day (2 d) after harvest is the most important demarcation point when the fruit has the same appearance as the freshly picked fruit (0 d); however, they are beginning to become water spot appearance. We performed a conjoint analysis of metabolome and transcriptome data for noni fruit of 0 d and 2 d to reveal what happened to the fruit at the molecular level. Genes and metabolites were annotated to KEGG pathways and the co-annotated KEGG pathways were used as a statistical analysis. Results We found 25 pathways that were significantly altered at both metabolic and transcriptional levels, including a total of 285 differentially expressed genes (DEGs) and 11 differential metabolites through an integrative analysis of transcriptomics and metabolomics. The energy metabolism and pathways originating from phenylalanine were disturbed the most. The upregulated resistance metabolites and genes implied the increase of resistance and energy consumption in the postharvest noni fruit. Most genes involved in glycolysis were downregulated, further limiting the available energy. This lack of energy led noni fruit to water spot appearance, a prelude to softening. The metabolites and genes related to the resistance and energy interacted and restricted each other to keep noni fruit seemingly hard within two days after harvest, but actually the softening was already unstoppable. Conclusions This study provides a new insight into the relationship between the metabolites and genes of noni fruit, as well as a foundation for further clarification of the post-ripening mechanism in noni fruit.

The Relationship

The relationship between wage inflation and unemployment (Phillips Curve) is controversial in economic thought, and the controversy is centered around whether there is always a trade-off or not. If this relationship is negative it is called The short-run Fillips Curve. However, in the long run, this relationship may probable not exist. The matter of how inflation and unemployment influence economic growth, is debatably among macroeconomic policymakers. This study examines the behavior of the Phillips Curve in Sudan and its effect on economic growth.

The Relationship

We study the relationship between career concerns and shared values empirically using employee–employer matched data for the United Kingdom and overtime hours as a proxy for hard work. In line with standard career-concerns theory, we find that employees work less overtime the longer they have been with their current employer. We also find that employees who agree strongly with the statement ‘I share many of the values of my organisation’ do roughly 20% more overtime than the rest. Our results suggest the existence of a trade-off between career concerns and shared values. We begin to consider some potential implications of this for employee recruitment as well as for the design of career paths across the private, public and voluntary sectors.

Shed Light

The aim of this study is to shed light on the movements of the mark-up rate for the case of Turkey following trade liberalization. For this purpose, first the relationship between labor and non-labor costs that lies behind the movements of the mark-up rates is analyzed, and second, the effect of trade liberalization on mark-up rates is tested. The trade-off between labor and non-labor costs is analyzed based on a model, which assumes that prices are set by a mark-up over average variable costs. The paper also tests the effect of international trade on the mark-up rate and the effect of the exchange rate via its effect on competitiveness and input costs using the panel data for the sub-sectors of private manufacturing industry. The most striking result of this analysis is the absence of any strong link between foreign trade and mark-up rates.

This article scrutinizes the assumption that friends support each other in times of war. Picking up the notion that solidarity, or ‘other-help’, is a key feature of friendship between states, the article explores how states behave when a friend is attacked by an overwhelming enemy. It directs attention to the trade-off between solidarity and self-help that governments face in such a situation and makes the novel argument that the decision about whether and how to support the friend is significantly influenced by assessments of the distribution of material capabilities and the relationship the state has with the aggressor. This proposition is supported empirically in an examination of Sweden’s response to its Nordic friends’ need for help during the Second World War – to Finland during the 1939–1940 ‘Winter War’ with the Soviet Union, and to Norway following the invasion of Germany from 1940 to 1945.

This chapter examines the relationship between European integration and democracy. The continuous transfer of policy-making powers from European Union (EU) member states to the European level has raised serious concerns about democratic legitimacy. The chapter assesses the claims that European integration undermines national democracy, and that decision-making at the EU level is not sufficiently democratic. It argues that while significant challenges remain, European integration has definitely become more democratic over the years. But there is perhaps a trade-off, with stronger input legitimacy potentially an obstacle to efficient European-level decision-making. It also underlines the multilevel nature of the EU polity and the importance of public debates about European integration.

The Relationship

Life-history theory predicts a trade-off between offspring size and number. However, the role of intra-litter phenotypic variation in shaping this trade-off is often disregarded. We compared the strength of the relationship between litter size and mass from the perspective of the lightest and the heaviest yearling offspring in 110 brown bear litters in Sweden. We showed that the mass of the lightest yearlings decreased with increasing litter size, but that the mass of the heaviest yearling remained stable, regardless of litter size. Consistent with a conservative reproductive strategy, our results suggest that mothers maintained a stable investment in a fraction of the litter, while transferring the costs of larger litter size to the remaining offspring. Ignoring intra-litter phenotypic variation may obscure our ability to detect a trade-off between offspring size and number.
