The present study was conducted to investigate the effect of digestion rate of dietary starch on postprandial systemic circulating glucose, insulin and lipid profiles, and the activity and gene expression of lipid metabolism-related enzymes in weaned pigs. A total of twenty-four weaned pigs, surgically fitted with a catheter in the jugular vein, were randomly assigned to three dietary treatment groups, representing the high digestion rate starch (HDRS) group, the moderate-digestion rate starch (MDRS) group and the low-digestion rate starch (LDRS) group. The amylopectin:amylose ratios in the diets of each group were 27·6:1, 27·6:8·5 and 1:27·6, respectively. The serum concentrations of glucose, TAG, total cholesterol, LDL-cholesterol and HDL-cholesterol in the HDRS group were increased to the peak point at postprandial 1·5, 2·5, 2·5, 1·5 and 1·5 h, those in the MDRS group were at postprandial 2·5, 3·5, 3·5, 3·5 and 3·5 h and those in the LDRS group were at postprandial 2·5, 3·5, 3·5, 1·5 and 3·5 h, respectively. The serum concentration of insulin in the HDRS group was higher (P < 0·05) than those in the MDRS group, and those in the MDRS group was also higher (P < 0·05) than those in the LDRS group at postprandial 0·5, 1·5 and 2·5 h, respectively. The serum concentrations of acetate, propionate and butyrate in the HDRS group were higher (P < 0·05) than those in the MDRS group, and those in the MDRS group were higher (P < 0·05) than in the LDRS group in each feeding cycle, in turn, respectively. The activity of fatty acid synthase (FAS) in the liver and abdominal adipose tissues, that of acetyl CoA carboxylase (ACC) in the myocardium and interscapular brown adipose tissues and that of the ATP-citrate lyase (ATP-CL) in the liver and interscapular brown adipose tissues in pigs of the HDRS group were higher (P < 0·05) than that of the MDRS group. The mRNA levels of FAS in the myocardium, liver and interscapular brown adipose tissues of pigs in the HDRS group were higher (P < 0·05) than those of the MDRS group. The activities and mRNA levels of FAS, ACC and ATP-CL in the myocardium, liver, abdominal and interscapular brown adipose tissues of the HDRS group were higher than those of the LDRS group. We conclude that the digestion rate of dietary starch affected not only the postprandial systemic circulating levels of glucose and insulin but also the lipid metabolism in weaned pigs. Dietary starch with higher digestion rate produces higher blood glucose and insulin response, ameliorates the blood lipid profiles and up-regulates the activity and gene expression profile of lipid metabolism-related genes in weaned pigs.
The influence of immigrant status and concentration on psychiatric disorder in Canada: a multi-level analysis
Authors: Menezes N. M. , Georgiades K. , Boyle M. H. 
Published: February 2011

BackgroundMany studies have reported an increased incidence of psychiatric disorder (particularly psychotic disorders) among first generation adult immigrants, along with an increasing risk for ethnic minorities living in low-minority concentration neighborhoods. These studies have depended mostly on European case-based databases. In contrast, North American studies have suggested a lower risk for psychiatric disorder in immigrants, although the effect of neighborhood immigrant concentration has not been studied extensively.MethodUsing multi-level modeling to disaggregate individual from area-level influences, this study examines the influence of first generation immigrant status at the individual level, immigrant concentration at the neighborhood-level and their combined effect on 12-month prevalence of mood, anxiety and substance-dependence disorders and lifetime prevalence of psychotic disorder, among Canadians.ResultsIndividual-level data came from the Canadian Community Health Survey (CCHS) 1.2, a cross-sectional study of psychiatric disorder among Canadians over the age of 15 years; the sample for analysis wasn=35 708. The CCHS data were linked with neighborhood-level data from the Canadian Census 2001 for multi-level logistic regression. Immigrant status was associated with a lower prevalence of psychiatric disorder, with an added protective effect for immigrants living in neighborhoods with higher immigrant concentrations. Immigrant concentration was not associated with elevated prevalence of psychiatric disorder among non-immigrants.ConclusionsThe finding of lower 12-month prevalence of psychiatric disorder in Canadian immigrants, with further lessening as the neighborhood immigrant concentration increases, reflects a model of person–environment fit, highlighting the importance of studying individual risk factors within environmental contexts.
Community Agency and Community Engagement: Re-theorising Participation in Governance
Authors: Eversole Robyn 
Published: February 2011

AbstractInterest in participatory governance recognises that communities can make valuable contributions to governance, but attempts to strengthen community participation encounter obstacles theorised as failures or incompleteness of participatory governance. This paper offers an alternative approach, drawing on ethnographic field data from a decade of work in rural Australian communities. It shows the nature of the community agency that is at the heart of policy interest in participation and how it differs from government efforts at community engagement. These insights suggest a need to rethink participatory governance, not as a single process with multiple participants, but as the juxtaposition of different ways of governing. Doing so opens up the possibility of governments and communities working together in new ways, with governments not only valuing what communities can contribute in theory, but also recognising how diverse communities work in practice.
Risk, Regulation and Crisis: Comparing National Responses in Food Safety Regulation
Authors: Lodge Martin 
Published: February 2011

AbstractThe literature on risk regulation often assumes a direct link between public pressure and regulatory responses. This article investigates whether the direction of regulatory response is related to public argumentation as expressed in the national print media. Three approaches are explored: national policy patterns, political panics expressed in Pavlovian politics, and policy responses shaped by universal policy paradigms. It assesses these three approaches in comparative perspective by looking at scandals in food safety regulation in Denmark, Germany and the US, looking at argumentation patterns in the national print media and using a coding system derived from grid-group cultural theory and regulatory responses. While all three countries display mostly hierarchical argumentation patterns, their actual regulatory responses point to diverse patterns.

Authors: Altuzarra O. , Şandru B. , Pinto Ch. , Petuya V. 
Published: February 2011

SUMMARYThis paper presents a new symmetric parallel Schönflies-motion generator. The design is an evolution of a previous robot with linear inputs. The complete kinematic analysis of the 4-degree-of-freedom (dof) parallel manipulator is presented. The degrees of freedom are obtained from the Group Theory, the direct and inverse position problems are solved obtaining the manipulator's workspace, and the Jacobian analysis is presented. Then the isotropic configurations of the manipulator are discussed and the local dexterity map within the workspace is produced. Finally, two alternatives of a rotational mechanical device, which will increase the angular end-effector range, are proposed.

Published: February 2011

SUMMARYThe A(H1N1) influenza pandemic has been a challenge for public health surveillance systems in all countries. An objective evaluation has not been conducted, as yet, of the performance of those systems during the pandemic. This paper presents an algorithm based on Benford's Law and the mortality ratio in order to evaluate the quality of the data and the sensitivity of surveillance systems. It analyses records of confirmed cases reported to the Pan American Health Organization by its 35 member countries between epidemiological weeks 13 and 47 in 2009. Seventeen countries did not fulfil Benford's Law, and mortality exceeded the regional average in 40% of the countries. The results suggest uneven performance by surveillance systems in the different countries, with the most frequent problem being low diagnostic coverage. Benford's Law proved to be a useful tool for the evaluation of a public health surveillance system's performance.
Textons and the Propagation of Space in Acousmatic Music
Authors: Nyström Erik 
Published: February 2011

The concepts introduced by Smalley in the context of space-form (2007) have firmly put acousmatic music on a discourse of spatial exploration, holding much potential for the developing of aesthetics in new directions. This article approaches space from the low level of musical structure, with a multi-dimensional attitude to space-form, exploring spatial texture, a concept introduced by Smalley to describe the temporal formations of space in spectromorphology (1997). Spatial articulation is investigated in the context of granular-oriented textures, proposing a micro-spatial, perceptual morphology – the texton – as an aesthetic approach to acousmatic music. This follows Albert Bregman's speculation regarding equivalents to visual perception in texture, where the theory of textons was first developed by the neuroscientist Béla Julesz.The article discusses acousmatic textons, in terms of intrinsic properties, the way they propagate in time, and how they organise in distributions to form spatial textures. The emergent macroscopic qualities of textonal formations are also reflected upon in the introduction of a group of textural states, where source-bonded spaces and abstract musical thinking coalesce.
Concretions in exhumed and inverted channels near Hanksville Utah: implications for Mars
Authors: Clarke Jonathan D. A. , Stoker Carol R. 
Published: February 2011

AbstractThe landscape near Hanksville, Utah, contains a diversity of Mars analogue features. These included segmented and inverted anastomosing palaeochannels exhumed from the Late Jurassic Brushy Basin Member of the Morrison Formation that hosts abundant small carbonate concretions. The exhumed and inverted channels closely resemble many seen on the surface of Mars in satellite imagery and which may be visited by surface missions in the near future. The channels contain a wealth of palaeoenvironmental information and are potentially of astrobiological interest, but intrinsically difficult terrain would make their study challenging on Mars. We show that an un-exhumed channel feature can be detected geophysically, and this may allow their study in more easily accessed terrain. The concretion's morphology and surface expression parallel the haematite ‘blue berries’ that are strewn across the surface of Meridiani Planum on Mars. They are best developed in poorly cemented medium to coarse channel sandstones and appear to have formed during deep burial.
A review of the literature on multiple symptoms, their predictors, and associated outcomes in patients with advanced cancer
Authors: Gilbertson-White Stephanie , Aouizerat Bradley E. , Jahan Thierry , Miaskowski Christine 
Published: February 2011

AbstractObjective:The findings from several studies suggest that palliative care patients with advanced cancer experience multiple symptoms, and that these symptoms may be related to demographic and clinical factors as well as to patient outcomes. However, no systematic review has summarized the findings from studies that assessed multiple symptoms, predictors, and outcomes in these patients. The purposes of this review, focused on palliative care patients with advanced cancer, are to: 1) describe the relationships among multiple symptoms; 2) describe the predictors of multiple symptoms; and 3) describe the relationships between multiple symptoms and patient outcomes.Method:Comprehensive literature searches were completed using the following databases: PubMed, Cumulative Index to Nursing and Allied Health Literature, and PsychInfo. The key words: cancer or advanced cancer or neoplasm, AND palliative care or terminal care or hospice or end-of-life, AND symptoms or multiple symptoms or symptom clusters were combined.Results:Twenty-two studies met the inclusion criteria and examined at least one of our purposes. The majority of these studies were descriptive and used one of four common symptom assessment scales. Fifty-six different signs and symptoms were evaluated across various dimensions (i.e., prevalence, severity, distress, frequency, control). Pain, dyspnea, and nausea were the only symptoms measured in all 22 studies. Relationships among concurrent symptoms were examined in nine studies. Relationships among symptoms and predictors (i.e., demographics, cancer type, healthcare delivery environment) were examined in seven studies. Relationships among symptoms and outcomes (i.e., functional status, psychological status, quality-of-life, survival time) were examined in 14 studies. Significant methodological variation was found among these studies.Significance of results:It is difficult to draw conclusions about the relationships among multiple symptoms, predictors, and outcomes due to the heterogeneity of these studies. Future research is needed to determine which symptoms and symptom dimensions to assess in order to better understand how multiple symptoms relate to each other as well to as predictors and outcomes in palliative care patients with advanced cancer.
The use of global abstractions: national income accounting in the period of imperial decline
Authors: Speich Daniel 
Published: February 2011

AbstractThis article explores the history of a conceptual world economic order of nations created by statistically minded economists over the last seventy years. Drawing upon work by Colin Clark, Richard Stone, and Simon Kuznets from the 1930s, 1940s, and 1950s, it reconstructs the rise of new economic indicators referring to economic inequality. Two forms of intellectual practice can be identified that characterized a remarkable shift in knowledge production in Anglo-American economics in the period of French and British imperial decline. One was new methods of counting and comparing income, which produced a sensational new view of the world as a place of enormous poverty. The other was the belief that these issues could be solved by applying a limited set of policy recommendations to all economies in the world.
Azinphos-methyl (AZM) phase-out: Actions and attitudes of apple growers in Washington State
Authors: Goldberger Jessica R. , Lehrer Nadine , Brunner Jay F. 
Published: February 2011

AbstractThe Environmental Protection Agency's phase-out of the pesticide azinphos-methyl (AZM) has encouraged the transition of apple pest management toward more environmentally and socially sustainable practices. This study reports on results of a 2009 survey of conventional apple growers in Washington State. Growers were asked about their approaches and attitudes toward the AZM phase-out and barriers to the adoption of reduced-risk insecticides (AZM-alternatives) as part of their integrated pest management (IPM) programs. Chi-square and analysis of variance (ANOVA) techniques were used to examine relationships between actions and attitudes toward the phase-out and grower characteristics. Results showed that Washington apple growers have begun eliminating AZM and adopting AZM-alternatives. However, larger growers (in terms of acreage and income) and growers more familiar with Washington State University's (WSU's) educational resources were more likely to have already reduced their AZM use. These results suggest that larger farms can play an important role in increasing the sustainability of conventional agriculture, despite a common association of sustainable agriculture with small farms. Results also suggest that agricultural extension services could be well served to extend their outreach to smaller growers and others lagging in the transition to more sustainable apple pest management.
A high-vacuum deposition system for in situ and real-time electrical characterization of organic thin-film transistors

Published: February 2011

We present a home-built high-vacuum system for performing organic semiconductor thin-film growth and its electrical characterization during deposition (real-time) or after deposition (in situ). Since the environment conditions remain unchanged during the deposition and electrical characterization process, a direct correlation between growth mode and electrical properties of thin film can be obtained. Deposition rate and substrate temperature can be systematically set in the range 0.1–10 ML/min and RT-150 °C, respectively. The sample-holder configuration allows the simultaneous electrical monitoring of up to five organic thin-film transistors (OTFTs). The OTFTs parameters such as charge carrier mobility μ, threshold voltage VTH, and the on–off ratio Ion/Ioff are studied as a function of the semiconductor thickness, with a submonolayer accuracy. Design, operation, and performance of the setup are detailed. As an example, the in situ and real-time electrical characterization of pentacene TFTs is reported.

306:1015–1018] in the Pacific Northwest and extends our knowledge back to 6,000 yr B.P. The results demonstrate that low-frequency drought/pluvial cycles, with occasional long-duration, multidecadal events, are a persistent feature of regional climate. Furthermore, the average duration of multidecadal wet/dry cycles has increased since the middle Holocene, which has acted to increase the amplitude and impact of these events. This is especially apparent during the last 1,000 yr. We suggest these transitions were driven by changes in the tropical and extratropical Pacific and are related to apparent intensification of the El Niño Southern Oscillation over this interval and its related effects on the Pacific Decadal Oscillation. The Castor Lake record also corroborates the notion that the 20th century, prior to recent aridity, was a relatively wet period compared to the last 6,000 yr. Our findings suggest that the hydroclimate response in the Pacific Northwest to future warming will be intimately tied to the impact of warming on the El Niño Southern Oscillation.
Fish as major carbonate mud producers and missing components of the tropical carbonate factory

Published: February 2011

Carbonate mud is a major constituent of recent marine carbonate sediments and of ancient limestones, which contain unique records of changes in ocean chemistry and climate shifts in the geological past. However, the origin of carbonate mud is controversial and often problematic to resolve. Here we show that tropical marine fish produce and excrete various forms of precipitated (nonskeletal) calcium carbonate from their guts (“low” and “high” Mg-calcite and aragonite), but that very fine-grained (mostly < 2 μm) high Mg-calcite crystallites (i.e.,

MgCO

) are their dominant excretory product. Crystallites from fish are morphologically diverse and species-specific, but all are unique relative to previously known biogenic and abiotic sources of carbonate within open marine systems. Using site specific fish biomass and carbonate excretion rate data we estimate that fish produce ∼6.1 × 10

kg CaCO

/year across the Bahamian archipelago, all as mud-grade (the < 63 μm fraction) carbonate and thus as a potential sediment constituent. Estimated contributions from fish to total carbonate mud production average ∼14% overall, and exceed 70% in specific habitats. Critically, we also document the widespread presence of these distinctive fish-derived carbonates in the finest sediment fractions from all habitat types in the Bahamas, demonstrating that these carbonates have direct relevance to contemporary carbonate sediment budgets. Fish thus represent a hitherto unrecognized but significant source of fine-grained carbonate sediment, the discovery of which has direct application to the conceptual ideas of how marine carbonate factories function both today and in the past.
Narrative case study research: On endings and six session reviews
Authors: Etherington Kim , Bridges Nell 
Published: February 2011

AbstractBackground: An in‐depth, small scale narrative inquiry into ex‐clients' experiences of counselling was undertaken, using a local community counselling agency which highlighted several important themes, including reviews and endings. Aim: To show clients' lived experience of reviews and endings. Methods: Narrative case study methods were used, alongside researcher reflexivity. The meanings were co‐constructed between the ex‐clients, their counsellors and the researchers. Results: Clients stories show the inter‐relationship between reviews and endings, and that even when experienced negatively, clients can see the value of reviews. This paper also notes the therapeutic importance of mutuality and negotiation in decision making about endings. Conclusions: The process of undertaking collaborative, narrative inquiry can be empowering for all involved. Clients, counsellors and managers can question funders about their assumptions about the number of sessions offered when they inform themselves with research.
Systematic case study research: A practice‐oriented introduction to building an evidence base for counselling and psychotherapy
Authors: McLeod John , Elliott Robert 
Published: February 2011

AbstractBackground: Historically, clinical case studies have played a central role in counselling and psychotherapy training and practice, by allowing practitioners to learn about ideas and interventions being developed by colleagues. In recent years, the development of methods for systematic collection and analysis of case data has made it possible for case study research to begin to make a contribution to the evidence base for therapy policy and practice. Aim: This paper provides an overview of the characteristics of rigorous case study research, introduces a set of studies that exemplify these principles, and reviews the relevance of systematic case study inquiry for policy, practice and training. Conclusions: If case study research is to fulfil its potential as a source of research‐based knowledge, it is essential for practitioners to publish more systematic case studies that document the range and scope of everyday therapeutic practice. It is also necessary to carry out further research into a variety of methodological issues associated with single‐case inquiry, as a means of further developing this approach to practice‐based research.
