Published: July 2010

The aim of this analysis was to investigate the strength of the association between sugar intake and treatment for dental decay in children in Scotland, and the impact of tooth brushing frequency on this association. The Survey of Sugar Intake among Children in Scotland was carried out in 2006 in those aged 3–17 years. Diet was assessed using the Scottish Collaborative Group FFQ, and interviews were carried out by trained fieldworkers who asked about dental health. A total of 1700 interviews were carried out, and 1512 FFQ were returned. Of the children, 56 % had received treatment for decay (fillings or teeth removed due to decay). Intake of non-milk extrinsic sugars (NMES), but not total sugar, increased the risk of having had treatment for decay: adjusted OR 1·84 (95 % CI 1·28, 2·64) for the highest ( ≥ 20·0 % food energy)v. lowest ( ≤ 14·8 % food energy) tertile of NMES intake. This raised risk remained in children who reported brushing their teeth at least twice a day. Compared with children who reported brushing their teeth at least twice a day and were in the lowest tertile of NMES intake, children who reported brushing their teeth once a day or less and were in the highest tertile of NMES intake were over three times more likely to have received treatment for decay (adjusted OR 3·39, 95 % CI 1·97, 5·82). In order to improve dental health in children in Scotland, dental health strategies must continue to stress the importance of both reduced NMES intake and good oral hygiene.
Feigning Weakness
Authors: Slantchev Branislav L. 
Published: July 2010

AbstractIn typical crisis bargaining models, strong actors must convince the opponent that they are not bluffing and the only way to do so is through costly signaling. However, in a war, strong actors can benefit from tactical surprise when their opponent mistakenly believes that they are weak. This creates contradictory incentives during the pre-war crisis: actors want to persuade the opponent of their strength to gain a better deal but, should war break out, they would rather have the opponent believe they are weak. I present an ultimatum crisis bargaining model that incorporates this dilemma and show that a strong actor may feign weakness during the bargaining phase. This implies that (1) absence of a costly signal is not an unambiguous revelation of weakness, (2) the problem of uncertainty is worse because the only actor with incentives to overcome it may be unwilling to do so, and (3) because of the difficulty with concealing resolve, democracies might be seriously disadvantaged in a crisis.
Transgovernmental Networks and Domestic Policy Convergence: Evidence from Insider Trading Regulation
Authors: Bach David , Newman Abraham L. 
Published: July 2010

AbstractCross-border cooperation among domestic regulators and public officials has become a defining feature of global governance. While a number of studies have tracked the emergence and institutionalization of such transgovernmental networks, less is known about their effect on domestic policy. This study explores this link for the important case of insider-trading regulation in original data for 116 countries between 1977 and 2006. It offers quantitative evidence that transgovernmental cooperation is related to domestic policy convergence but that the relationship is more complex than often assumed. Direct ties to powerful regulators increases a jurisdiction's likelihood of adopting internationally promoted policies such as insider-trading rules. Separately, membership in the International Organization of Securities Commissions (IOSCO), a forum designed to diffuse best practices among regulators, increases a jurisdiction's likelihood of subsequently enforcing newly adopted policies. The findings in this study suggest that different network components are associated with distinct aspects of domestic policy convergence. The results are directly relevant for current public policy debates about the reregulation of global financial markets as transgovernmental networks among domestic regulators have assumed a critical role.
Labor Markets and the Demand for Foreign Direct Investment
Authors: Pandya Sonal S. 
Published: July 2010

AbstractExisting research on foreign direct investment (FDI) focuses on how politics influences the supply of FDI inflows. In this article I shift focus to the demand for FDI inflows within recipient countries by examining individual preferences for FDI. I argue that FDI preferences are largely a function of FDI's effects on income. FDI raises wages, especially those of skilled labor because foreign firms require more highly skilled labor than their local counterparts. Accordingly, support for FDI should increase with respondents' skills. Using three years of extensive public opinion data from eighteen Latin American countries, I provide robust evidence that preferences are consistent with FDI's effects on income. There is relatively little support for alternate explanations including concerns about job security, opposition to privatization, and the socializing effects of higher education on economic policy preferences.
Reality Asserts Itself: Public Opinion on Iraq and the Elasticity of Reality
Authors: Baum Matthew A. , Groeling Tim 
Published: July 2010

AbstractPrevailing theories hold that U.S. public support for a war depends primarily on its degree of success, U.S. casualties, or conflict goals. Yet, research into the framing of foreign policy shows that public perceptions concerning each of these factors are often endogenous and malleable by elites. In this article, we argue that both elite rhetoric and the situation on the ground in the conflict affect public opinion, but the qualities that make such information persuasive vary over time and with circumstances. Early in a conflict, elites (especially the president) have an informational advantage that renders public perceptions of “reality” very elastic. As events unfold and as the public gathers more information, this elasticity recedes, allowing alternative frames to challenge the administration's preferred frame. We predict that over time the marginal impact of elite rhetoric and reality will decrease, although a sustained change in events may eventually restore their influence. We test our argument through a content analysis of news coverage of the Iraq war from 2003 through 2007, an original survey of public attitudes regarding Iraq, and partially disaggregated data from more than 200 surveys of public opinion on the war.
Virgil'sGeorgicsand the Dating of Propertius’ First Book
Authors: Heslin Peter 
Published: July 2010

ABSTRACTThis article re-examines a passage in the first book of Propertius which has generally been interpreted as establishing that the collection was published after Actium. In fact, these lines do not necessarily allude to Antony's defeat, but fit even better with the situation in the years leading up to the battle. Once that has been established, the balance of evidence supports a considerably earlier date for Propertius’ first book. This prompts a re-evaluation of the direction of influence between it and Virgil'sGeorgics. Contrary to traditional assumptions, Virgil can be seen to have reacted strongly to the elegist's brilliant debut.
The unipolar society: the value of an international society approach to preponderance
Authors: PLUNKETT JAMES 
Published: July 2010

AbstractThis article aims to reassert the relevance of the international society approach by highlighting the value it could bring to the project of understanding the effects of unipolarity. Bull's approach to war and international law as ‘institutions of international society’ could help to frame our understanding of the way in which preponderance has impacted on war and law. Examining the phenomenon of bilateralism suggests that there is also value in a more general attempt to trace the effects of unipolarity on international society.
Exel's crossed product for non-unital C*-algebras
Authors: BROWNLOWE NATHAN , RAEBURN IAIN , VITTADELLO SEAN T. 
Published: July 2010

AbstractWe consider a family of dynamical systems (A, α, L) in which α is an endomorphism of a C*-algebra A and L is a transfer operator for α. We extend Exel's construction of a crossed product to cover non-unital algebras A, and show that the C*-algebra of a locally finite graph can be realised as one of these crossed products. When A is commutative, we find criteria for the simplicity of the crossed product, and analyse the ideal structure of the crossed product.
Tackling the drivers of child undernutrition in developing countries: what works and how should interventions be designed?
Authors: Pridmore Pat , Carr-Hill Roy 
Published: July 2010

AbstractObjectiveThe present paper presents a synthesis of available evidence to support action on the interventions that can effectively address the main drivers of child undernutrition in developing countries. It also discusses how interventions should be designed and identifies policy-relevant areas for further research.DesignA structured literature review of fifty-eight controlled evaluations and studies in developing countries were selected because they are methodologically sound, recent (reported within the past 10 years), report on nutritional status, cover a wide range of interventions and are implemented by a range of different agencies.SettingIndirect interventions in developing countries, which address the underlying and basic causes of child undernutrition and can potentially be implemented in the short to medium term.SubjectsChildren under 5 years of age and their mothers across a range of developing countries.ResultsEvidence has now accumulated to guide action on a range of indirect interventions that can reduce child undernutrition, but for all these interventions context is all-important. There is less evidence on how these interventions can be effectively implemented on a large scale.ConclusionsEfforts should be directed towards improving implementation of effective interventions on a large scale. Donors need to keep commitments both in dollar terms and in terms of the Paris Declaration so that the push for improved nutrition does not become donor driven. At the country level, there is a need for enabling governance structures, institutions and evidence-based decision making. Within countries there is a need for well-trained personnel with delegated authority, accountable to local people. It is essential for chains of accountability to be transparent and for active involvement of households in decision-making processes.
Effects of Bifidobacterium bifidum on adaptive immune senescence in aging mice
Authors: Fu Yu‐Rong , Yi Zheng‐Jun , Pei Jing‐liang , Guan Shizhen 
Published: July 2010

ABSTRACT Bifidobacteria are a natural component of the bacterial flora of the human body and have a symbiotic bacteria‐host relationship with human beings. Aging is associated with reduced numbers of beneficial colonic Bifidobacteria and impaired immunity. The possible anti‐senescence effects of Bifidobacteria are presently unknown. The aims of the present study were to investigate possible anti‐senescence effects of B. bifidum on naturally senescent mice and to explore their mechanisms. After treatment with B. bifidum, mice were killed and samples collected. Cytokine production in serum and lymphocyte culture supernatant, anti‐oxidation activity and gene expression were measured. B. bifidum significantly increased cytokine IL‐2 and IFN‐γ levels but decreased proinflammatory cytokines IL‐6 and TNF‐α concentrations. Moreover, B. bifidum improved anti‐oxidation activity and reduced lipid peroxidation in thymus and spleen. In addition, B. bifidum down‐regulated p16 expression in thymus and spleen. Taken together, the results indicate, for the first time, that B. bifidum delays senescence by several mechanisms, including enhancement of anti‐oxidation activity in thymus and spleen, alteration of gene expression and improvement in immune function.
Ocular morbidity in hearing impaired schoolchildren
Authors: Bist J. , Adhikari P. , Sharma A. K. 
Published: July 2010

AbstractAims  To determine the pattern and prevalence of ocular morbidity in hearing impaired schoolchildren.Methods  A cross‐sectional descriptive study was conducted in the three different deaf schools of Kathmandu, Bhaktapur and Kavre districts. All children in the deaf school underwent complete ocular examination. Examination included visual acuity assessment, refraction, binocular vision assessment, and anterior and posterior segment evaluation.Results  Ocular examination was carried out in 279 children with age range within 5 to 20 years (mean age 14.1 ± 3.14 years). Ocular morbidity was detected in 78 (28%) children with 46 (16.48%) having refractive errors. Seventy eight percent children did not have corrective lenses despite having refractive errors. Two children were found to have pigmentary retinopathy where electro‐retinogram findings suggested Usher's Syndrome in one child. Another child was found to have Waardenburg Syndrome.Conclusions  Hearing impaired children are at an increased risk of having ocular morbidity. Hence, periodic eye examinations are important in deaf children.
Immunohistochemistry of ultrastructural changes in scarring lupus erythematosus
Authors: Al-Refu K. , Goodfield M. 
Published: July 2010

Summary
Background. The various clinical types of lupus erythematosus (LE) show an essentially similar histological picture, and the subsets of LE cannot easily be distinguished by histology alone. However, there is an important clinical difference: lesions of discoid LE (DLE) cause scarring, particularly on the scalp, whereas lesions of subacute and acute LE heal without scarring. The focal thickening of the basement membrane zone (BMZ) in DLE lesions represents an important histopathological finding, and there is little known about the nature of these alterations at the BMZ level.
Aim. To investigate BMZ alterations in the basement membrane zone (BMZ) in cutaneous LE (CLE) by immunohistochemistry.
Methods. Skin biopsies from 30 patients with CLE [DLE and subacute CLE (SCLE)] and from 10 controls were studied using antibodies to cytokeratin 5, cytokeratin 14, bullous pemphigoid (BP)180, BP230, plectin, laminin 5, collagen IV and collagen VII.
Results. There was increased expression of components of the lamina lucida, lamina densa and anchoring fibrils in active DLE, whereas expression was normal in SCLE and control tissues, and in areas of scarring in DLE. In addition, higher expression of the hemidesmosome-associated antigens (BP230 and plectin) was found in active DLE. The expression of other antigens was similar in all tissues examined.
Conclusions. These alterations in the BMZ suggest that the BMZ may react in a different way in active DLE than in SCLE, and that the BMZ may remodel in different ways. These immunohistochemical differences may provide a new method of histological differentiation between the various LE subtypes.

M. C. Cummings, B. A. Waters and P. K. O’Rourke Breast fine needle aspiration cytology: a review of current practice in Australasia Aims:  To investigate breast fine needle aspiration (FNA) cytology in Australasia, in terms of laboratory demographics, specimens received and quality control (QC).Methods:  A questionnaire was sent to all laboratories enrolled in the FNA module of the Royal College of Pathologists of Australasia Cytopathology Quality Assurance Program (QAP), requesting information about specimens received in a 3‐month period in 2001 and in 2008.Results:  Responses were received from 81/180 laboratories in 2001 and from 94/200 in 2008. The mean number of cases per 3 months was 137 in 2001 and 141 in 2008 and for the 42 laboratories responding on both occasions, the mean number of cases declined from 191 to 149 (P = 0.001). The mean percentage of malignant cases was 11.7% in 2001 and 10.5% in 2008 and the mean percentages of unsatisfactory rates were 21.7% and 25.2%, respectively; 43.2% of laboratories in 2001 and 40.4% in 2008 reported fewer than 50 cases for the 3‐month period. The unsatisfactory rate was inversely proportional to the number of cases received. Most QC (69.1% in 2001, 71.3% in 2008) was carried out by correlation with any later histology. With no histology available, 35.8% of laboratories in 2001 and 48.9% in 2008 did no further follow‐up. Follow‐up of all diagnostic categories increased from 30.9% in 2001 to 44% in 2008.Conclusions:  Breast FNA cytology is still actively undertaken in Australasia, but numbers have declined. Unsatisfactory rates have reached the Australian recommended upper limit and are inversely proportional to the total number of cases received. Overall QC measures are unchanged and consideration of a review of breast FNA guidelines is suggested.
Species richness facilitates ecosystem resilience in aquatic food webs
Authors: DOWNING AMY L. , LEIBOLD MATHEW A. 
Published: July 2010

Summary1. Many studies indicate that biodiversity in ecosystems affects stability, either by promoting temporal stability of ecosystem attributes or by enhancing ecosystem resistance and resilience to perturbation. The effects on temporal stability are reasonably well understood and documented but effects on resistance and resilience are not.2. Here, we report results from an aquatic mesocosm experiment in which we manipulated the species richness and composition of aquatic food webs (macrophytes, macro‐herbivores and invertebrate predators), imposed a pulse disturbance (acidification), and monitored the resistance (initial response) and resilience (recovery) of ecosystem productivity and respiration.3. We found that species‐rich macroinvertebrate communities had higher resilience of whole‐ecosystem respiration, but were not more resistant to perturbations. We also found that resilience and resistance were unaffected by species composition, despite the strong role composition is known to play in determining mean levels of function in these communities.4. Biodiversity’s effects on resilience were probably mediated through complex pathways affecting phytoplankton and microbial communities (e.g. via changes in nutrient regeneration, grazing or compositional changes) rather than through simpler effects (e.g. insurance effects, enhanced facilitation) although these simpler mechanisms probably played minor roles in enhancing respiration resilience.5. Current mechanisms for understanding biodiversity’s effects on ecosystem stability have been developed primarily in the context of single‐trophic level communities. These mechanisms may be overly simplistic for understanding the consequences of species richness on ecosystem stability in complex, multi‐trophic food webs where additional factors such as indirect effects and highly variable life‐history traits of species may also be important.
Review article: Basic steps in adapting response surface methodology as mathematical modelling for bioprocess optimisation in the food systems
Authors: Nwabueze Titus U. 
Published: July 2010

SummaryTechniques involving choosing process combinations for optimisation without due consideration for relevant experimental designs is scientifically unreliable and irreproducible. Mathematical modelling, of which response surface methodology (RSM) is one, provides a precise map leading to successful optimisation. This paper identified key process variables, building the model and searching the solution through multivariate regression analysis, interpretation of resulting polynomial equations and response surface/contour plots as basic steps in adapting the central composite design to achieve process optimisation. It also gave information on appropriate RSM software packages and choice of order in RSM model and data economy in reducing the factorial experiments from large number parameter combinations to a far less number without losing any information including quadratic and interaction (if present) effects. It is expected that this paper will afford many food scientists and researchers the opportunity for adapting RSM as a mathematical model for achieving bioprocess optimisation in food systems.
Original article: Antifungal activities of cinnamon oil against Rhizopus nigricans, Aspergillus flavus and Penicillium expansum in vitro and in vivo fruit test
Authors: Xing Yage , Li Xihong , Xu Qinglian , Yun Juan , Lu Yaqing 
Published: July 2010

SummaryThe postharvest pathogens such as R. nigricans, A. flavas and P. expansum are the causal agents of jujube or orange fruit, therefore, in vitro and in vivo antifungal activities of cinnamon oil to inactivate these fungi were investigated. Cinnamaldehyde is the main constituent of cinnamon oil. The minimum inhibitory concentrations of cinnamon oil against Rhizopus nigricans, Aspergillus flavus and Penicillium expansum were 0.64% (v/v), 0.16% (v/v) and 0.16% (v/v), respectively. The antifungal activity of cinnamon oil against A. flavus and P. expansum was stronger than that against R. nigricans and the activity was improved with increasing its concentration. In an in vivo study, cinnamon oil with concentrations of 2.0% (v/v) and 3.0% (v/v) showed complete control the growth of fungi in wound‐inoculated Lingwu Long Jujube and Sand Sugar Orange fruits. These results revealed that cinnamon oil has a good potential to be as a natural antifungal agent for fruit applications.
Original article: Thermal pretreatment and chemical modifications as a means to alter hydrolytic characteristics and prevent bitterness in hydrolysates of fishery by‐catch (Decapterus maruadsi) protein
Authors: Liu Tong‐Xun , Zhao Mou‐Ming 
Published: July 2010

SummaryIn this study, fishery by‐catch protein (Decapterus maruadsi) was first thermal treated (60–100 °C), phosphorylated (0.5–4.0 g g−1 protein) or succinylated (0.05–0.3 g g−1 protein) before hydrolysis to prevent the bitterness of the resulting hydrolysate. Hydrolysis was performed at 50 °C, 10 h, pH 8.0 by Alcalase. Results showed that thermal treatment upon 80 °C, succinylation and phosphorylation resulted in significant decrease in amino acid content and increase in larger peptide content (>1450 Da). Succinylation did not reduce the bitterness as a result of higher content of small peptides (<550 Da), which was found to be correlated positively with the bitterness of hydrolysates. However, thermal treatment, especially phosphorylation, could reduce the bitterness to discernible level, indicating that phosphorylation before hydrolysis could be a potential means to prevent the evolution of bitter flavour which restricts the practical uses of the hydrolysates.
