AbstractObjective: The purpose of this study was to determine whether color Doppler sonogram can accurately depict the placental vascular structures using a latex cast model of the placental vessels, and to make a nomogram of several blood flow parameters according to the vascular structures.Methods: First, we made 9 latex cast models of placental arteries and performed morphologic observation and measurement. Second, the comparative anatomical observation of placental vessels by color flow mapping was performed for all 9 patients from whom the latex models were made. Third, a total of 102 uncomplicated pregnant women between 18 and 40 weeks gestation were examined by color Doppler imaging. The resistance indices (RI) and peak systolic velocity (PSV) were measured.Results: In the latex cast model of placentas, cotyledons could be differentiated by the presence of independent vascular structure units. First, second, third and fourth branches were noted in one cotyledon. Cotyledons were easily identified and counted by color Doppler imaging. Each cotyledon contained only one first branch of the intraplacental villous artery (IPVA). The number of IPVA‐1 on color Doppler imaging was equal to the number of the cotyledon calculated from the latex model. RI exhibited a negative, and PSV a positive correlation with gestational age (p < 0.05 in both cases). At any given gestational age, both RI and PSV in the peripheral arteries were significantly lower (p < 0.01) than those in the upstream arteries.Conclusions: Color Doppler flow sonography is a valuable tool for detecting the blood flow of intraplacental villous arteries in vivo and the images agree with the vascular anatomy of placenta in vitro. These results may also provide the basic parameters for future studies of some complicated pregnancies.
ALTERNATING MONOPOLY AND TACIT COLLUSION*
Authors: Amelio Andrea , Biancini Sara 
Published: May 2010

AbstractThis paper considers the use of the alternating monopoly strategy (AMS) as a (tacit) collusion device. We show that firms may choose this strategy in particular environments, when other collusive strategies are also feasible. In particular, we stress how the presence of an observable move (entry), distinct from the competitive stage (price setting), can serve as a coordination device, reducing monitoring costs in incomplete information environments. The paper thus shows that AMS may be preferable to the classic market sharing strategy (MSS) and in some cases it is the only collusive equilibrium.
ROBUST ESTIMATION OF SMALL‐AREA MEANS AND QUANTILES
Authors: Tzavidis Nikos , Marchetti Stefano , Chambers Ray 
Published: May 2010

SummarySmall‐area estimation techniques have typically relied on plug‐in estimation based on models containing random area effects. More recently, regression M‐quantiles have been suggested for this purpose, thus avoiding conventional Gaussian assumptions, as well as problems associated with the specification of random effects. However, the plug‐in M‐quantile estimator for the small‐area mean can be shown to be the expected value of this mean with respect to a generally biased estimator of the small‐area cumulative distribution function of the characteristic of interest. To correct this problem, we propose a general framework for robust small‐area estimation, based on representing a small‐area estimator as a functional of a predictor of this small‐area cumulative distribution function. Key advantages of this framework are that it naturally leads to integrated estimation of small‐area means and quantiles and is not restricted to M‐quantile models. We also discuss mean squared error estimation for the resulting estimators, and demonstrate the advantages of our approach through model‐based and design‐based simulations, with the latter using economic data collected in an Australian farm survey.
Rural‐to‐Urban Commuting: Three Degrees of Integration
Authors: PARTRIDGE MARK D. , ALI KAMAR , OLFERT M. ROSE 
Published: May 2010

ABSTRACTCommuting ties between rural places of residence and urban places of employment are among the most visible forms of rural–urban integration. For some rural areas, access to urban employment is a key source of population retention and growth. However, this access varies considerably across rural areas, with distance representing a primary deterrent. In addition to distance, the size of the urban community will also influence rural‐to‐urban commuting opportunities. In this paper, using Canadian data, we empirically estimated the influence of local rural population and job growth on rural out‐commuting within the urban hierarchy. We find consistent support for the deconcentration hypothesis where population moves to rural areas for lifestyle and quality of life reasons, while retaining urban employment. Further, we find some evidence that in addition to distance from the nearest urban center being a deterrent, increased remoteness from the top of the urban hierarchy exerts a positive influence on out‐commuting. Recognition of these types of rural–urban linkages through commuting is essential in designing Canadian rural policy and targeted programs that may effectively support local rural populations. In particular, they point to the need to have reasonable transportation infrastructure for urban accessibility, which should be complemented by other “built” infrastructure to improve the livability of rural communities.
Novel EGF pathway regulators modulate C. elegans healthspan and lifespan via EGF receptor, PLC‐γ, and IP3R activation

SummaryImproving health of the rapidly growing aging population is a critical medical, social, and economic goal. Identification of genes that modulate healthspan, the period of mid‐life vigor that precedes significant functional decline, will be an essential part of the effort to design anti‐aging therapies. Because locomotory decline in humans is a major contributor to frailty and loss of independence and because slowing of movement is a conserved feature of aging across phyla, we screened for genetic interventions that extend locomotory healthspan of Caenorhabditis elegans. From a group of 54 genes previously noted to encode secreted proteins similar in sequence to extracellular domains of insulin receptor, we identified two genes for which RNAi knockdown delayed age‐associated locomotory decline, conferring a high performance in advanced age phenotype (Hpa). Unexpectedly, we found that hpa‐1 and hpa‐2 act through the EGF pathway, rather than the insulin signaling pathway, to control systemic healthspan benefits without detectable developmental consequences. Further analysis revealed a potent role of EGF signaling, acting via downstream phospholipase C‐γplc‐3 and inositol‐3‐phosphate receptor itr‐1, to promote healthy aging associated with low lipofuscin levels, enhanced physical performance, and extended lifespan. This study identifies HPA‐1 and HPA‐2 as novel negative regulators of EGF signaling and constitutes the first report of EGF signaling as a major pathway for healthy aging. Our data raise the possibility that EGF family members should be investigated for similar activities in higher organisms.

SummaryThe usefulness of the right precordial unipolar leads and the value of the bipolar lead CM5 in the detection of coronary artery disease (CAD) with exercise electrocardiographic (ECG) test are not well documented. The objective of this study was to evaluate the diagnostic performance of leads V4R and CM5. The study population comprised 579 patients referred for a bicycle exercise ECG test in the Finnish Cardiovascular Study. Patients were divided into three groups: angiographically proven CAD (CAD, n = 255), no CAD by angiography (NoCAD, n = 126), and low likelihood of CAD (LLC, n = 198). The maximum ST‐segment depression at peak exercise was used as a parameter, and the diagnostic accuracy of different leads was assessed by receiver operating characteristic (ROC) analysis. Sensitivity and specificity values at a cut‐off criterion of −0·10 mV ST‐segment, 1‐mm ST depression, were determined. According to the results, incorporating lead V4R with the standard leads decreased the ROC area from 0·71 to 0·69 (comparison CAD versus LLC) and from 0·55 to 0·53 (comparison CAD versus NoCAD) and had no effect on sensitivity or specificity. Adding lead CM5 to the standard leads did not affect the ROC area but increased the sensitivity and decreased the specificity. In conclusion, the use of right precordial lead V4R along with the standard 12‐lead system does not improve the performance of the exercise ECG in diagnosing CAD. Adding lead CM5 to the standard leads increases the sensitivity but does not change the overall diagnostic performance.
Phase equilibria and metamorphic evolution of glaucophane‐bearing UHP eclogites from the Western Dabieshan Terrane, Central China

Published: May 2010

AbstractGlaucophane‐bearing ultrahigh pressure (UHP) eclogites from the western Dabieshan terrane consist of garnet, omphacite, glaucophane, kyanite, epidote, phengite, quartz/coesite and rutile with or without talc and paragonite. Some garnet porphyroblasts exhibit a core–mantle zoning profile with slight increase in pyrope content and minor or slight decrease in grossular and a mantle–rim zoning profile characterized by a pronounced increase in pyrope and rapid decrease in grossular. Omphacite is usually zoned with a core–rim decrease in j(o) [=Na/(Ca + Na)]. Glaucophane occurs as porphyroblasts in some samples and contains inclusions of garnet, omphacite and epidote. Pseudosections calculated in the NCKMnFMASHO system for five representative samples, combined with petrographic observations suggest that the UHP eclogites record four stages of metamorphism. (i) The prograde stage, on the basis of modelling of garnet zoning and inclusions in garnet, involves P–T vectors dominated by heating with a slight increase in pressure, suggesting an early slow subduction process, and P–T vectors dominated by a pronounced increase in pressure and slight heating, pointing to a late fast subduction process. The prograde metamorphism is predominated by dehydration of glaucophane and, to a lesser extent, chlorite, epidote and paragonite, releasing ∼27 wt% water that was bound in the hydrous minerals. (ii) The peak stage is represented by garnet rim compositions with maximum pyrope and minimum grossular contents, and P–T conditions of 28.2–31.8 kbar and 605–613 °C, with the modelled peak‐stage mineral assemblage mostly involving garnet + omphacite + lawsonite + talc + phengite + coesite ± glaucophane ± kyanite. (iii) The early decompression stage is characterized by dehydration of lawsonite, releasing ∼70–90 wt% water bound in the peak mineral assemblages, which results in the growth of glaucophane, j(o) decrease in omphacite and formation of epidote. And, (iv) The late retrograde stage is characterized by the mineral assemblage of hornblendic amphibole + epidote + albite/oligoclase + quartz developed in the margins or strongly foliated domains of eclogite blocks due to fluid infiltration at P–T conditions of 5–10 kbar and 500–580 °C. The proposed metamorphic stages for the UHP eclogites are consistent with the petrological observations, but considerably different from those presented in the previous studies.
Managing Multiple Facets of Risk in New Product Alliances*
Authors: Lee Ruby P. , Johnson Jean L. 
Published: May 2010

ABSTRACTThe trend of forming alliances to develop new products continues; however, many of these new product alliances fail. As such we explore how key risk types intrinsic in new product alliances, performance, relational, and knowledge appropriation risks, influence alliance success. Further, we theorize that different alliance governance mechanisms can reduce the negative impact of risks on alliance success. To disentangle possible heterogeneous factors across firms that may affect the interplay of risk assessments and the use of governance mechanisms, we employ latent class regression analysis on survey data collected from 128 new product alliance firms and find support for a two‐regime solution. Longer alliance relationships and lower technological turbulence are factors for some firms (regime one), while the opposite are factors for other firms (regime two). These two regimes show different patterns in the interplay of risk assessments and governance for alliance success. Our theory and results support viewing risk as a multiple‐factor concept and by understanding the different impacts of the risk types in new product alliances and how governance mechanisms mitigate such effects, we aid managers' decision making regarding the balance of contractual versus normative governance in new product alliances. Understanding the heterogeneous factors inherent in these complex relationships enables managers to understand the conditions in which various governance mechanisms promote new product alliance success.
On Decisions for Integration Implementation: An Examination of Complementarities Between Product‐Process Technology Integration and Supply Chain Integration
Authors: Narasimhan Ram , Swink Morgan , Viswanathan Sridhar 
Published: May 2010

ABSTRACTResearch has shown that both product‐process technology (PPT) integration and supply chain integration efforts produce operational benefits, yet synergies between these types of integration are not well understood. This article empirically examines strategic customer integration and supplier integration as complementary activities for PPT integration, with the aim of helping manufacturing plant managers to intelligently implement mutually supportive types of integration. We set two conditions for establishing complementarity: (i) one type of strategic integration must positively influence the adoption of another and (ii) the two types of strategic integration must exhibit a synergistic fit with respect to manufacturing plant capabilities. We test these conditions using survey results representing 224 manufacturing plants. The findings show positive complementarities between PPT integration and supplier integration with respect to quality, delivery, and process flexibility. Also, positive complementarities exist between PPT integration and customer integration with respect to quality and new product flexibility. The results extend the emerging theory of strategic value chain integration and provide guidance to manufacturing managers who wish to assemble strategic integration policies.

AbstractNeutrophil gelatinase‐associated lipocalin (NGAL) protein is an early biomarker for acute kidney injury (AKI). It is unknown if extracorporeal therapies (EC) have an effect on circulating NGAL levels. This study was designed to describe the kinetics of NGAL molecule in different EC techniques and to evaluate NGAL clearance in different operational conditions. A mock hemofiltration (HF) and hemoperfusion (HP) setup was used. NGAL was added to the blood reservoir and then measured at 30‐minute intervals from arterial, venous, and ultrafiltrate (UF) lines. Removal kinetics and NGAL sieving coefficient were calculated. In our experiments, baseline NGAL concentration averaged 452 μg/L. There was a consistent downward trend throughout the experiment. NGAL concentration in the UF was between 80 and 90 μg/L, though it showed a slight increase in the second hour. The sieving coefficient of NGAL ranged from 0.2 to 0.4 during HF and it appeared to increase with time, suggesting an initial effect of membrane adsorption. HP proved clearly that there was adsorption of NGAL by the membrane and the point of saturation occured at approximately 60 minutes from the start of circulation. Our evaluation demonstrates that NGAL can be adsorbed and ultrafiltrated with polysulfone membranes. This should be taken into consideration when using NGAL as an AKI biomarker in patients undergoing EC circulation.
DOES ETHICAL THEORY HAVE A PLACE IN POST‐KOHLBERGIAN MORAL PSYCHOLOGY?
Authors: Maxwell Bruce 
Published: May 2010

Philosophers tend to assume that theoretical frameworks in psychology suffer from conceptual confusion and that any influence that philosophy might have on psychology should be positive. Going against this grain, Dan Lapsley and Darcia Narváez attribute the Kohlbergian paradigm's current state of marginalization within psychology to Lawrence Kohlberg's use of ethical theory in his model of cognitive moral development. Post‐Kohlbergian conceptions of moral psychology, they advance, should be wary of theoretical constructs derived from folk morality, refuse philosophical starting points, and seek integration with literatures in psychology, not philosophy. In this essay, Bruce Maxwell considers and rejects Lapsley and Narváez's diagnosis. The Kohlbergian paradigm's restricted conception of the moral domain is the result of a selective reading of one tendency in ethical theorizing (Kantianism). The idea that moral psychology may find shelter from normative criticism by avoiding ethics‐derived models overlooks the deeper continuity between “ethical theory” and “psychological theory.”
The confusion and barrenness of psychology is not to be explained by calling it a “young science”; its state is not comparable with that of physics, for instance, in its beginnings. (Rather with that of certain branches of mathematics. Set theory.) For in psychology there are experimental methods and conceptual confusion. (As in the other case conceptual confusion and methods of proof.)The existence of the experimental method makes us think we have the means of solving the problems which trouble us; though problem and method pass one another by.1
Intimate partner violence against Japanese and non‐Japanese women in Japan: A cross‐sectional study in the perinatal setting
Authors: INAMI Eriko , KATAOKA Yaeko , ETO Hiromi , HORIUCHI Shigeko 
Published: May 2010

AbstractAim: To identify the prevalence of intimate partner violence (IPV) against Japanese women (JW) and non‐Japanese women (NJW) in a perinatal setting. Additional purposes were to identify the associated factors of IPV, describe the characteristics of IPV against NJW, and assess the acceptability of the Violence Against Women Screen (VAWS) instrument as a screening tool.Methods: A cross‐sectional survey was conducted from September to November 2007 in an urban hospital maternity clinic in Tokyo, Japan. Women who attended the maternity clinic received the VAWS instrument, which was translated into four languages (Japanese with Kanji and Hiragana, English, Chinese, and Tagalog) and was used to identify IPV.Results: A total of 400 women participated in the study: 357 were JW and 43 were NJW. The prevalence rate of IPV among the JW was 31.4% and 21.4% among the NJW. There was no statistical significance between the two groups. A multiple logistic regression with adjusted odds ratio identified two associated factors for IPV: being multipara and previous experience of physical violence from a partner.Conclusion: The prevalence of IPV was not statistically different among JW and NJW. Screening for IPV, early intervention, and support should be expanded in hospitals and maternity clinics in Japan.

Abstract An endoplasmic reticulum‐localized tomato ω‐3 fatty acid desaturase gene (LeFAD3) was isolated. The antisense tomato plants were obtained under the control of the cauliflower mosaic virus 35S promoter (35S‐CaMV). Northern blot analysis confirmed that the expression of LeFAD3 was inhibited in the tomato genome. Levels of 18:3 decreased and correspondingly levels of 18:2 increased in total lipids of leaves and roots. After heat stress, the fresh weight of the aerial parts of antisense transgenic plants was higher than that of the wild type (WT) plants. The membrane system ultrastructure of chloroplasts in leaf cells and all of the subcellular organelles in the root tips of transgenic plants remained more intact than those of WT. Relative electric conductivity increased less in transgenic plants than in WT. Under heat stress, the maximal photochemical efficiency of photosystem II (Fv/Fm) and the O2 evolution rate decreased more in WT than in transgenic plants. These results suggested that the depletion of LeFAD3 increased the saturation of fatty acids and alleviated high temperature stress.

AbstractAim:  To survey the use of anthropometry by dietitians.Methods:  Respondents to an anonymous online survey were recruited from the dietetic workforce in Victoria, Australia. The survey recorded demographic information, category of dietetic practice and client type. Questions were also asked about use and confidence in taking anthropometric measures and about enablers and barriers for this within dietetic practice.Results:  The 151 dietitians who completed the survey resembled the wider Victorian dietetic workforce. Most (93%) considered anthropometry an important tool. Body weight and height were measures most commonly taken. Over 30% used surrogate measures for height such as ulna length. Other measures including circumferences, knee height, sitting height and skinfold thicknesses were taken infrequently. Factors facilitating use of anthropometry were prior experience; training; a mobile consenting client and/or the availability of clear procedures or protocols. Barriers to taking circumferences and skinfold thicknesses included lack of confidence, time and support from senior colleagues. Most respondents indicated the need for additional training in anthropometry.Conclusions:  The practice of anthropometry in accordance with practice guidelines would be improved by strengthening professional training and the provision of more supportive, well‐resourced systems.
