PERSISTENCE OF PRICE-COST MARGINS IN THE U.S. FOOD AND TOBACCO MANUFACTURING INDUSTRIES: A DYNAMIC SINGLE INDEX MODEL APPROACH

Persistence of price-cost margins in the U.S. food and tobacco manufacturing industries is measured while accounting for price-cost margin risk. Direct measurement of persistence and of long- and short-run price-cost margin risk is accomplished by incorporating a partial-adjustment framework into the Single Index Model. Results indicate persistence of price-cost margins. Short-run margin risk is accounted for primarily by diversifiable risk. Long-run margin risk, which depends on systematic risk alone, is generally lower than the short-run measure. Factors influencing persistence and the systematic relationship between industry margins and a market index are explored.
Shoulder pain in the Swiss spinal cord injury community: prevalence and associated factors

Abstract Purpose: To determine the prevalence of shoulder pain and to identify factors associated with shoulder pain in a nationwide survey of individuals living with spinal cord injury (SCI) in Switzerland. Methods: Data was collected through the 2012 community survey of the Swiss SCI Cohort Study (SwiSCI) (N = 1549; age 52.3 ± 14.8; 29% female). Sociodemographic and socioeconomic circumstances, SCI characteristics, health conditions as well as mobility independence and sporting activities were evaluated as predictor variables. Analyses were adjusted for item non-response (using multiple imputation) and unit-nonresponse (using inverse probability weighting). Results: The adjusted prevalence of shoulder pain was 35.8% (95% CI: 33.4–38.3). Multivariable regression analysis revealed higher odds of shoulder pain in females as compared to males (odds ratio: 1.89; 95% CI: 1.44–2.47), and when spasticity (1.36; 1.00–1.85) and contractures (2.47; 1.91–3.19) were apparent. Individuals with complete paraplegia (1.62; 1.13–2.32) or any tetraplegia (complete: 1.63; 1.01–2.62; incomplete: 1.82; 1.30–2.56) showed higher odds of shoulder pain compared to those with incomplete paraplegia. Conclusions: This survey revealed a high prevalence of shoulder pain. Sex, SCI severity, and specific health conditions were associated with having shoulder pain. Implications for rehabilitation Individuals with spinal cord injury have a high prevalence of shoulder pain. Females, individuals with complete paraplegia or any tetraplegia and individuals with contractures and spasticity should receive considerable attention in rehabilitation programmes due to their increased odds of having shoulder pain.
Reduced functional connectivity between salience and visual networks in migraine with aura

Background Migraine with visual aura (MA) is associated with distinct visual disturbances preceding migraine attacks, but shares other visual deficits in between attacks with migraine without aura (MO). Here, we seek to determine if abnormalities specific to interictal MA patients exist in functional brain connectivity of intrinsic cognitive networks. In particular, these networks are involved in top-down modulation of visual processing. Methods Using resting-state functional magnetic resonance imaging, whole-brain functional connectivity maps were derived from seeds placed in the anterior insula and the middle frontal gyrus, key nodes of the salience and dorsal attention networks, respectively. Twenty-six interictal MA patients were compared with 26 matched MO patients and 26 healthy matched controls. Results The major findings were: connectivity between the anterior insula and occipital areas, including area V3A, was reduced in MA but not in MO. Connectivity changes between the anterior insula and occipital areas further correlated with the headache severity in MA only. Conclusions The unique pattern of connectivity changes found in interictal MA patients involved area V3A, an area previously implicated in aura generation. Hypoconnectivity to this and other occipital regions may either represent a compensatory response to occipital dysfunctions or predispose MA patients to the development of aura.
Recent thymic emigrants are tolerized in the absence of inflammation

CD4+ and CD8+ recent thymic emigrants (RTEs) exhibit an anergic phenotype after encounter with self-antigen in the periphery. In the presence of inflammation, both CD4+ and CD8+ RTEs can be converted into competent diabetogenic effector cells.
Assessing Youth Perceptions and Knowledge of Agriculture: The Impact of Participating in an AgVenture Program

Agricultural education programs such as AgVenture have been established to educate youth about the importance of agriculture. The study reported here examined the direct impact that one agricultural education program, specifically AgVenture, had on youth perceptions and knowledge of agriculture. Youth's perceptions and knowledge of agriculture were examined using a pre-test and post-test instrument administered to fourth grade students who participated in the AgVenture program. It was concluded that the AgVenture program was significantly associated with student knowledge. Student perceptions were also affected by the activity.
The Effects of Market Properties on Portfolio Diversification in the Korean and Japanese Stock Markets

In this study, we have investigated empirically the effects of market properties on the degree of diversification of investment weights among stocks in a portfolio. The weights of stocks within a portfolio were determined on the basis of Markowitz's portfolio theory. We identified that there was a negative relationship between the influence of market properties and the degree of diversification of the weights among stocks in a portfolio. Furthermore, we noted that the random matrix theory method could control the properties of correlation matrix between stocks; this may be useful in improving portfolio management for practical application.
The Political Economy Of Mexico's Dollarization Debate

Between 1998 and 2002 Mexico was host to an intense debate over dollarization. This paper examines the conjunctural factors which led to the emergence of this debate, reviews the main participants in the debate and their arguments, and discusses why the debate ended. We further argue that the Mexican debate can best be understood not as one between rival ideological positions but between different, say, mainstream neoliberal positions. There is no mainstream consensus on the preferred form of the institutional governance of money. The Mexican debate on dollarization reflects this rather than simply the imperatives of global market pressures.
Leniency and Whistleblowers in Antitrust

The paper reviews the recent evolution of leniency programs for cartels in the US and EU, surveys their theoretical economic analyses, and discusses the empirical and experimental evidence available, also looking briefly at related experiences of rewarding whistleblowers in other fields of law enforcement. It concludes with a list of desiderata for leniency and whistleblower reward programs, simple suggestions how to improve current ones, and an agenda for future research. The issues discussed appear relevant to the fight of other forms of multiagent organized crime - like auditor-manager collusion, financial fraud, or corruption - that share with cartels the crucial features that well designed leniency and whistleblower programs exploit.
Acanthamoeba culbertsoni Elicits Soluble Factors That Exert Anti-Microglial Cell Activity

ABSTRACT Acanthamoeba culbertsoni is an opportunistic pathogen that causes granulomatous amoebic encephalitis (GAE), a chronic and often fatal disease of the central nervous system (CNS). A hallmark of GAE is the formation of granulomas around the amoebae. These cellular aggregates consist of microglia, macrophages, lymphocytes, and neutrophils, which produce a myriad of proinflammatory soluble factors. In the present study, it is demonstrated that A. culbertsoni secretes serine peptidases that degrade chemokines and cytokines produced by a mouse microglial cell line (BV-2 cells). Furthermore, soluble factors present in cocultures of A. culbertsoni and BV-2 cells, as well as in cocultures of A. culbertsoni and primary neonatal rat cerebral cortex microglia, induced apoptosis of these macrophage-like cells. Collectively, the results indicate that A. culbertsoni can apply a multiplicity of cell contact-independent modes to target macrophage-like cells that exert antiamoeba activities in the CNS.
Developmentally Sensitive Measures of Executive Function in Preschool Children

Changes in executive functioning in the preschool years are recognized as playing a critical role in cognitive and social development, yet comprehensive data and recommendations about measurement of these changes are lacking. The performance of 602 preschool children on several executive function tasks was analyzed and reported as (a) age trends in performance and (b) task difficulty scales at 2, 3, 4, and 5 to 6 years of age. This analysis informs theories of executive function development and offers researchers an evidence-based guide to task selection and design.
Unemployment, Inflation, and Wages in the American Depression: are There Lessons for Europe?

In this paper, we consider whether there are lessons to be drawn from the experience of the American economy during the 1930's for the current European situation. The comparison reveals some important differences: In particular, the persistence of American unemployment in the 1930's reflected to a much greater degree a sequence of large destabilizing shocks, and much less a low-level equilibrium trap, than does modern European unemployment. The self-correcting tendencies of the 1930's U.S. economy were probably much stronger than is generally acknowledged. However, the experience of the Depression era confirms the modern observation that the level of unemployment does not much affect the rate of inflation--an observation that, we argue, is consistent with macro theory. The Depression experience also supports the impression that political factors are important in real wage determination.
The collective consciousness of Information Technology research: The significance and value of research projects. B. The views of IT industry professionals

This research seeks to reveal the different perceptual worlds in a research community, with the longterm intent of fostering increased understanding and hence collaboration. In the relatively new field of information technology (IT) research, available evidence suggests that a shared understanding of the research object or territory does not yet exist. This has led to the development of different perceptions amongst IT researchers of what constitutes significant and valuable research. Phenomenological methodology is used to elicit data from a diverse range of IT industry professionals in semi-structured interviews. This data is presented to show (1) the variation in meaning associated with the idea of significance and value and (2) the awareness structures through which participants experience significance and value. An Outcome Space represents the interrelation between those different ways of seeing, revealing a widening awareness. Five categories of ways of seeing the significance and value of research projects were found: The Personal Goals Conception, The Commercial Goals Conception, The Outcomes for the Technology End User Conception, The Solving Real-World Problems Conception and The Design of the Research Project Conception. These are situated within three wider perceptual boundaries: The Individual, The Enterprise and Society. The categories are described in detail, demonstrated with participants’ quotes and illustrated with diagrams. A tentative comparison is made between this project and a similar investigation of IT researchers’ ways of seeing the significance and value of IT research projects. Finally, some recommendations for further research are made.
Association of pre-pregnancy body mass index with offspring metabolic profile: Analyses of 3 European prospective birth cohorts

Background A high proportion of women start pregnancy overweight or obese. According to the developmental overnutrition hypothesis, this could lead offspring to have metabolic disruption throughout their lives and thus perpetuate the obesity epidemic across generations. Concerns about this hypothesis are influencing antenatal care. However, it is unknown whether maternal pregnancy adiposity is associated with long-term risk of adverse metabolic profiles in offspring, and if so, whether this association is causal, via intrauterine mechanisms, or explained by shared familial (genetic, lifestyle, socioeconomic) characteristics. We aimed to determine if associations between maternal body mass index (BMI) and offspring systemic cardio-metabolic profile are causal, via intrauterine mechanisms, or due to shared familial factors. Methods and findings We used 1- and 2-stage individual participant data (IPD) meta-analysis, and a negative-control (paternal BMI) to examine the association between maternal pre-pregnancy BMI and offspring serum metabolome from 3 European birth cohorts (offspring age at blood collection: 16, 17, and 31 years). Circulating metabolic traits were quantified by high-throughput nuclear magnetic resonance metabolomics. Results from 1-stage IPD meta-analysis (N = 5327 to 5377 mother-father-offspring trios) showed that increasing maternal and paternal BMI was associated with an adverse cardio-metabolic profile in offspring. We observed strong positive associations with very-low-density lipoprotein (VLDL)-lipoproteins, VLDL-cholesterol (C), VLDL-triglycerides, VLDL-diameter, branched/aromatic amino acids, glycoprotein acetyls, and triglycerides, and strong negative associations with high-density lipoprotein (HDL), HDL-diameter, HDL-C, HDL2-C, and HDL3-C (all P < 0.003). Slightly stronger magnitudes of associations were present for maternal compared with paternal BMI across these associations; however, there was no strong statistical evidence for heterogeneity between them (all bootstrap P > 0.003, equivalent to P > 0.05 after accounting for multiple testing). Results were similar in each individual cohort, and in the 2-stage analysis. Offspring BMI showed similar patterns of cross-sectional association with metabolic profile as for parental pre-pregnancy BMI associations but with greater magnitudes. Adjustment of parental BMI–offspring metabolic traits associations for offspring BMI suggested the parental associations were largely due to the association of parental BMI with offspring BMI. Limitations of this study are that inferences cannot be drawn about the role of circulating maternal fetal fuels (i.e., glucose, lipids, fatty acids, and amino acids) on later offspring metabolic profile. In addition, BMI may not reflect potential effects of maternal pregnancy fat distribution. Conclusion Our findings suggest that maternal BMI–offspring metabolome associations are likely to be largely due to shared genetic or familial lifestyle confounding rather than to intrauterine mechanisms.
Access policy and practice in further and higher education: investigating “success” as access turns into widening participation

The policy shift to widen participation in recent years has emerged using language associated with radical, practitioner-led discourses on post compulsory education and training (PCET) of the 1970s and 80s and even from earlier periods. This research focuses on the underrepresented student experience and perceptions of success within the PCET system. It uses a mainly qualitative approach to analyse the experience of staff and students in two further education (FE) colleges and two universities with traditions of widening access to underrepresented groups to explore good practice in widening access to further and higher education, the support services, student-centred administration as well as institutional policies and barriers to widening access. It also examines, from the perspectives of senior managers, teachers and students, institutional polices and practices to support the success of underrepresented groups. The research showed some evidence of changes within institutions but found that staff practices and administration processes had not changed to meet the diversified participation. What was in evidence was a largely unchanged provision requiring the student to change. The successful student experience, for higher education (HE) certainly and mature students generally, identity was personal and strong, community links remain in the home. The HE institution is not somewhere you go to live, as campus based, ‘traditional’ students. The theories on success and retention of Tinto and others therefore need revisiting in light of the ‘new’ student population. The research evidence suggests a different context of successful access to PCET for ‘non-traditional’ students and the failure of the case study institutions to identify and accommodate it. The research found hard working but frustrated staff in FE and HE, and dissatisfied but determined students. The research concludes with recommendations for policy makers and PCET institutions.
A survey of a mixed species aviary provides new insights into the pathogenicity, diversity, evolution, host range, and distribution of psittacine and passerine adenoviruses

ABSTRACT A Bourke’s parrot (Neopsephotus bourkii) originating from an aviary in Australia, containing two species of parrots, five species of finch and a species of dove, was presented for necropsy. The Bourke’s parrot died from gastritis caused by Macrorhabdus ornithogaster, but also had an interstitial nephritis and ureteritis with adenovirus-like inclusion bodies within collecting duct epithelial cells. The adenovirus causing the lesions was shown to be Psittacine adenovirus-2 (PsAdV-2) using a PCR assay specific for adenoviruses and sequencing of amplicons. A survey of droppings from other birds in the aviary using the same PCR assay with amplicon sequencing found a high prevalence of infection of PsAdV-2 in Bourke's and scarlet-chested parrots (Neophema splendida). PsAdV-2 was also present in droppings from a Namaqua dove (Oena capensis). Gouldian finches (Erythrura gouldiae), red-billed firefinches (Lagonosticta senegala), and red-throated parrot finches (Erythrura psittacea) were shedding Gouldian finch adenovirus-1 (GFAdV-1). Two novel adenoviruses, an atadenovirus and a siadenovirus, were detected in the droppings from long-tailed finches (Poephila acuticauda). Kidney tissue from three of four scarlet-chested parrots submitted for necropsy from a second aviary were also positive for PsAdv-2. These findings and previously reported findings of widespread PsAdv-2 infection in captive orange-bellied parrots (Neophemia chrysogaster) raise the possibility that PsAdV-2 is enzootic in Australian aviculture. This represents the first report of GFAdV-1 in Australia and first identification of infection in finch species other than the Gouldian finch. Identification of two novel adenoviruses in long-tailed finches suggests that other novel adenoviruses are circulating in other finch species. RESEARCH HIGHLIGHTS Psittacine adenovirus-2 was present in high prevalence in two Australian aviaries. Gouldian finch adenovirus-1 (GFAdV-1) was detected in Australia for the first time. The host range of GFAdV-1 host range was expanded to other finch species. Novel atadenovirus and siadenovirus were detected in Estrildid finches.
Intracochlear Pressure Changes due to 2 Electrode Types: An Artificial Model Experiment

Objective To preserve residual hearing in cochlear implant surgery, the electrode design has been refined, and an atraumatic insertion has become one aspect of cochlear implant research. Previous studies have described the effect of insertion speed and opening of the round window membrane on intracochlear pressure changes. The aim of our current study was to observe intracochlear pressure changes due to different cochlear implant electrodes in an artificial cochlear model with stable surrounding factors. Study Design Prospective controlled study. Setting Tertiary referral center. Subjects and Methods The experiments were performed in an artificial cochlear model with a pressure sensor in the apical area. With straight and perimodiolar electrode arrays, 5 insertions with the same insertion speed and 5 insertions over the same time were performed. Results With the perimodiolar high-volume electrode, significantly greater intracochlear fluid pressure changes were observed than with the straight electrode. Compared with the straight electrode, the perimodiolar electrode induces significantly higher pressure peaks (1.12 ± 0.15 vs 0.86 ± 0.05 mm Hg, P = .006) and significantly higher amplitudes (0.38 ± 0.07 vs 0.09 ± 0.07 mm Hg, P < .001). Conclusion The reliable preservation of residual hearing is an important multifactorial challenge in modern cochlear implant surgery. Insertion speed, handling, and electrode design are known to influence the preservation of residual hearing. In our artificial model experiments, we could prove objectively that the volume of the electrodes has a significant influence on the intracochlear pressure changes during cochlear implantation.
Electrical properties of atomic layer deposited aluminum oxide on gallium nitride

We report on our investigation of the electrical properties of metal/Al2O3/GaN metal-insulator-semiconductor capacitors. We determined the conduction band offset and interface charge density of the alumina/GaN interface by analyzing the capacitance-voltage characteristics of atomic layer deposited Al2O3 films on GaN substrates. The conduction band offset at the Al2O3/GaN interface was calculated to be 2.13 eV, in agreement with theoretical predications. A non-zero field of 0.93 MV/cm in the oxide under flat-band conditions in the GaN was inferred, which we attribute to a fixed net positive charge density of magnitude 4.60 × 1012 cm−2 at the Al2O3/GaN interface. We provide hypotheses to explain the origin of this charge by analyzing the energy band line-up.
Life Cycle Greenhouse Gas Emissions of Nuclear Electricity Generation

A systematic review and harmonization of life cycle assessment (LCA) literature of nuclear electricity generation technologies was performed to determine causes of and, where possible, reduce variability in estimates of life cycle greenhouse gas (GHG) emissions to clarify the state of knowledge and inform decision making. LCA literature indicates that life cycle GHG emissions from nuclear power are a fraction of traditional fossil sources, but the conditions and assumptions under which nuclear power are deployed can have a significant impact on the magnitude of life cycle GHG emissions relative to renewable technologies.
Swedish Real Estate as a hedge against inflation : With comparison to stocks, bonds and golds

The objective of this research is to analyze residential, unsecuritized and securitized real estates’ ability to hedge inflation in Sweden and compare it to stocks’, bonds’ and gold’s ability to hedge inflation.This research is based on both descriptive statistical and econometric analysis methodology with use of both quarterly and annual data series. First are the correlations between assets and actual, expected and unexpected inflation analyzed. Inflation betas are then estimated for all assets based on an ordinary least square model. The results indicate that, during the researched period 1993-2011, none of the studied exposures of real estate are a hedge against actual, expected nor unexpected inflation. As expected the results also indicate that both stocks and bonds have a negative relation to inflation, while gold seems to be a partial hedge against inflation. However, all inflation betas have a low R square and low statistical significance in general. Real estate in Sweden is not a hedge against inflation as it traditionally is perceived to be and real estate returns might be driven by business cycles, accessibility to financing and expectations of interest rates rather than inflation.
