Purpose – The purpose of this paper is to shed new light on the debate about the role of foreign direct investment (FDI) and public policy in fostering economic development. Specifically, can the capital inflow of multinational enterprises (MNEs) and the ability of the subsidiaries to raise funds locally help promote development? This paper addresses this issue by examining the capital structure and financing sources of foreign subsidiaries of MNEs. Design/methodology/approach – This paper integrates the capital structure theories in finance with internalization theory in international business. It uses an original primary dataset collected by a survey of 101 foreign subsidiaries of British MNEs in six emerging economies in the ASEAN region. Findings – There are three significant findings. First, these subsidiaries rely heavily on internal funds generated within the MNEs and less on external debts raised in the host countries. Second, the foreign subsidiary's capital structure is influenced by the home country of origin of the parent firm and the parent firm's financing sources. Third, these subsidiaries have used the financial resources to develop business networks with local small and medium enterprises (SMEs) which contribute to economic development of the host countries. Originality/value – This paper examines the internal capital market within the MNE. It provides theoretical and empirical support for the capital structure theory of the hierarchy financing approach and also for internalization theory by addressing FDI inflows by MNEs and the raising of funds locally. These findings have important implications for public policy, namely the facilitation of MNE entry to encourage economic development.

Background Flavonoids are a group of phenolic secondary plant metabolites that are ubiquitous in plant-based diets. Data from anthropological, observational and intervention studies have shown that many flavonoids are bioactive. For this reason, there is an increasing interest in investigating the potential health effects of these compounds. The translation of these findings into the context of the health of the general public requires detailed information on habitual dietary intake. However, only limited data are currently available for European populations. Objective The objective of this study is to determine the habitual intake and main sources of anthocyanidins, flavanols, flavanones, flavones, flavonols, proanthocyanidins, theaflavins and thearubigins in the European Union. Design We use food consumption data from the European Food Safety Authority (EFSA) and the FLAVIOLA Food Composition Database to estimate intake of flavonoids. Results Mean (±SEM) intake of total flavonoids in Europe was 428±49 mg/d, of which 136±14 mg/d were monomeric compounds. Gallated flavan-3-ols (53±12 mg/d) were the main contributor. The lowest flavonoid intake was observed in Mediterranean countries (monomeric compounds: 95±11 mg/d). The distribution of intake was skewed in many countries, especially in Germany (monomeric flavonoids; mean intake: 181 mg/d; median intake: 3 mg/d). Conclusions The habitual intake of flavonoids in Europe is below the amounts found to have a significant health effect.

Photorhabdus are highly effective insect pathogenic bacteria that exist in a mutualistic relationship with Heterorhabditid nematodes. Unlike other members of the genus, Photorhabdus asymbiotica can also infect humans. Most Photorhabdus cannot replicate above 34°C, limiting their host-range to poikilothermic invertebrates. In contrast, P. asymbiotica must necessarily be able to replicate at 37°C or above. Many well-studied mammalian pathogens use the elevated temperature of their host as a signal to regulate the necessary changes in gene expression required for infection. Here we use RNA-seq, proteomics and phenotype microarrays to examine temperature dependent differences in transcription, translation and phenotype of P. asymbiotica at 28°C versus 37°C, relevant to the insect or human hosts respectively. Our findings reveal relatively few temperature dependant differences in gene expression. There is however a striking difference in metabolism at 37°C, with a significant reduction in the range of carbon and nitrogen sources that otherwise support respiration at 28°C. We propose that the key adaptation that enables P. asymbiotica to infect humans is to aggressively acquire amino acids, peptides and other nutrients from the human host, employing a so called “nutritional virulence” strategy. This would simultaneously cripple the host immune response while providing nutrients sufficient for reproduction. This might explain the severity of ulcerated lesions observed in clinical cases of Photorhabdosis. Furthermore, while P. asymbiotica can invade mammalian cells they must also resist immediate killing by humoral immunity components in serum. We observed an increase in the production of the insect Phenol-oxidase inhibitor Rhabduscin normally deployed to inhibit the melanisation immune cascade. Crucially we demonstrated this molecule also facilitates protection against killing by the alternative human complement pathway.

BACKGROUND: Several clones of extended-spectrum β-lactamase (ESBL)–producing extraintestinal pathogenic Escherichia coli (ExPEC) have globally expanded their distribution. ExPEC infections often originate from the patient’s own intestinal flora, although the degree of overlap between diarrheagenic E. coli and ExPEC pathotypes is unclear. Relatively little is known about antimicrobial drug resistance in the most common diarrheagenic E. coli groups, including enteroaggregative E. coli (EAEC), and bacterial gastroenteritis is generally managed without use of antimicrobial drugs. APPROACHES: We conducted this study to establish the presence and characteristics of ESBL-producing EAEC in a well-defined collection of ESBL-producing isolates. The isolates were from human and animal sources in Germany, the Netherlands, and the United Kingdom. DNA from 359 ESBL isolates was screened for the presence of the EAEC transport regulator gene (aggR), located on the EAEC plasmid, using a real-time PCR assay and the phylogroup was determined for each positive isolate. A microarray was used to detect ESBL genes, such as blaCTX-M, at the group level, as previously described. The antimicrobial drug susceptibilities of EAEC isolates were determined and virulence factors associated with intestinal and extraintestinal infection and with EAEC were investigated . RESULTS AND CONCLUSIONS: We assigned a virulence score (total number of virulence factor genes detected; maximum possible score 22) and a resistance score (total number of drug classes; maximum score 11) to each isolate. We isolated 11 EAEC from humans. Eight of the EAEC were isolated from urine specimens, and 1 was isolated from a blood culture; 63% belonged to phylogroup D (Table). EAEC ST38, the most common (55%) ST, was significantly associated with extraintestinal sites in the subset of 140 human isolates (Fisher exact test, p<0.0001)

In 2013, an opportunity arose in England to develop an agri-environment package for wild pollinators, as part of the new Countryside Stewardship scheme launched in 2015. It can be understood as a 'policy window', a rare and time-limited opportunity to change policy, supported by a narrative about pollinator decline and widely supported mitigating actions. An agri-environment package is a bundle of management options that together supply sufficient resources to support a target group of species. This paper documents information that was available at the time to develop such a package for wild pollinators. Four questions needed answering: (1) Which pollinator species should be targeted? (2) Which resources limit these species in farmland? (3) Which management options provide these resources? (4) What area of each option is needed to support populations of the target species? Focussing on wild bees, we provide tentative answers that were used to inform development of the package. There is strong evidence that floral resources can limit wild bee populations, and several sources of evidence identify a set of agri-environment options that provide flowers and other resources for pollinators. The final question could only be answered for floral resources, with a wide range of uncertainty. We show that the areas of some floral resource options in the basic Wild Pollinator and Farmland Wildlife Package (2% flower-rich habitat and 1 km flowering hedgerow), are sufficient to supply a set of six common pollinator species with enough pollen to feed their larvae at lowest estimates, using minimum values for estimated parameters where a range was available. We identify key sources of uncertainty, and stress the importance of keeping the Package flexible, so it can be revised as new evidence emerges about how to achieve the policy aim of supporting pollinators on farmland.

The Sick Child in Early Modern England is a powerful exploration of the treatment, perception, and experience of illness in childhood, from the late sixteenth to the early eighteenth centuries. At this time, the sickness or death of a child was a common occurrence - over a quarter of young people died before the age of fifteen - and yet this subject has received little scholarly attention. Hannah Newton takes three perspectives: first, she investigates medical understandings and treatments of children. She argues that a concept of 'children's physic' existed amongst doctors and laypeople: the young were thought to be physiologically distinct, and in need of special medicines. Secondly, she examines the family's' experience, demonstrating that parents devoted considerable time and effort to the care of their sick offspring, and experienced feelings of devastating grief upon their illnesses and deaths. Thirdly, she takes the strikingly original viewpoint of sick children themselves, offering rare and intimate insights into the emotional, spiritual, physical, and social dimensions of sickness, pain, and death. Newton asserts that children's experiences were characterised by profound ambivalence: whilst young patients were often tormented by feelings of guilt, fears of hell, and physical pain, sickness could also be emotionally and spiritually uplifting, and invited much attention and love from parents. Drawing on a wide array of printed and archival sources, The Sick Child is of vital interest to scholars working in the interconnected fields of the history of medicine, childhood, parenthood, bodies, emotion, pain, death, religion, and gender.

The chapter is an investigation of the child’s emotional response to death in early modern England. While much valuable scholarship has been produced on parents’ responses to the deaths of children, the reactions of the young themselves have rarely been explored. Drawing on a range of printed and archival sources, I argue that children expressed diverse and conflicting emotions, from fear and anxiety, to excitement and ecstasy. By exploring the emotional experiences of Protestants, the chapter contributes to the bourgeoning literature on emotion and religion, and contests earlier depictions of reformed Protestantism as an inherently intellectual, rather than an affective, faith. This study also suggests that we revise the way we classify the emotions, resisting the intuitive urge to categorise them as ‘positive’ or ‘negative’. The fear of hell, for example, though profoundly unpleasant, was regarded as a rational, commendable response, which demonstrated the work of the Holy Spirit in the soul, and was a prerequisite for the attainment of a joyful assurance of heaven. An underlying question is to what extent children’s responses to death differed from those of adults. I propose that although their reactions were broadly similar, the precise preoccupations of dying children were different. Through highlighting these distinctive features, we can come to a closer idea of what it was like to be a child in the early modern period.
