“To Get Rich Is Not Only Glorious”: Economic Reform and the New Entrepreneurial Party Secretaries
Authors: Xiaojun Yan 
Published: May 2012

AbstractThis article examines the profound transformation market reforms have brought to the leadership of the Chinese Communist Party's (CCP) rural grassroots organizations. Focusing on the political rise of private entrepreneurs and other economically successful individuals who recently obtained village Party secretary appointments in a north China county, the article explores their differing promotion channels, power bases, political resources and motivations to take up the CCP's grassroots leadership position. It demonstrates that the variety among the new entrepreneurial Party secretaries – from large factory owners to de facto farm managers – shaped the network resource, factional affiliation and socio-political capital they rely upon to exercise their newly attained power. It also shows the crucial role played by community-based endogenous forces in transmitting the power of economic liberalization into dynamics for the reshuffling of the Communist Party leadership at the grassroots level.

AbstractThe goal of this study was an administration of the navigation task in a three-dimensional virtual environment to localize the electroencephalogram (EEG) features responsible for egocentric and allocentric reference frame processing in a horizontal and also in a vertical plane. We recorded the EEG signal of a traverse through a virtual tunnel to search for the best signal features that discriminate between specific strategies in particular plane. We identified intrahemispheric coherences in occipital–parietal and temporal–parietal areas as the most discriminative features. They have 10% lower error rate compared to single electrode features adopted in previous studies. The behavioral analysis revealed that 11% of participants switched from egocentric to allocentric strategy in a vertical plane, while 24% of participants consistently adopted egocentric strategy in both planes.
Manipulating accumulative functions by swapping call-time and return-time computations

Published: May 2012

AbstractFunctional languages are suitable for transformational developments of programs. However, accumulative functions, or in particular tail-recursive functions, are known to be less suitable for manipulation. In this paper, we propose a program transformation named “IO swapping” that swaps call-time and return-time computations. It moves computations in accumulative parameters to results and thereby enables interesting transformations. We demonstrate effectiveness of IO swapping by several applications: deforestation, higher order removal, program inversion, and manipulation of circular programs.
Performance Validity and Symptom Validity in Neuropsychological Assessment
Authors: Larrabee Glenn J. 
Published: May 2012

AbstractFailure to evaluate the validity of an examinee's neuropsychological test performance can alter prediction of external criteria in research investigations, and in the individual case, result in inaccurate conclusions about the degree of impairment resulting from neurological disease or injury. The terms performance validity referring to validity of test performance (PVT), and symptom validity referring to validity of symptom report (SVT), are suggested to replace less descriptive terms such as effort or response bias. Research is reviewed demonstrating strong diagnostic discrimination for PVTs and SVTs, with a particular emphasis on minimizing false positive errors, facilitated by identifying performance patterns or levels of performance that are atypical for bona fide neurologic disorder. It is further shown that false positive errors decrease, with a corresponding increase in the positive probability of malingering, when multiple independent indicators are required for diagnosis. The rigor of PVT and SVT research design is related to a high degree of reproducibility of results, and large effect sizes of d=1.0 or greater, exceeding effect sizes reported for several psychological and medical diagnostic procedures.

Symptom Validity Testing, Effort, and Neuropsychological Assessment
Authors: Bigler Erin D. 
Published: May 2012

AbstractSymptom validity testing (SVT) has become a major theme of contemporary neuropsychological research. However, many issues about the meaning and interpretation of SVT findings will require the best in research design and methods to more precisely characterize what SVT tasks measure and how SVT test findings are to be used in neuropsychological assessment. Major clinical and research issues are overviewed including the use of the “effort” term to connote validity of SVT performance, the use of cut-scores, the absence of lesion-localization studies in SVT research, neuropsychiatric status and SVT performance and the rigor of SVT research designs. Case studies that demonstrate critical issues involving SVT interpretation are presented. (JINS, 2012,18, 1–11)
Infant and young child feeding practices and child undernutrition in Bangladesh: insights from nationally representative data

Published: May 2012

AbstractObjectiveTo determine the association between indicators of infant and young child feeding (IYCF) and anthropometric measures of nutritional status among children aged 0–23 months in a nationally representative data set.DesignData from the 2007 Bangladesh Demographic and Health Survey were used. Analyses were conducted using multiple linear regression and logistic regression analyses adjusted for the complex survey design of the survey, controlling for child, maternal and household characteristics, and including regional dummy variables.SettingBangladesh.SubjectsPairs (n 2096) of last born infants and their mothers.ResultsExclusive breast-feeding under 6 months of age was associated with higher weight-for-height Z-score (effect size (ES) = 0·29; P < 0·05). Appropriate complementary feeding in children aged 6–8 months was associated with higher height-for-age Z-score (HAZ; ES = 0·63; P < 0·01) and higher weight-for-age Z-score (WAZ; ES = 0·30; P < 0·05). Higher dietary diversity index (DDI) was associated with higher HAZ (ES = 0·08; P < 0·01 for every 1 point higher DDI) and higher WAZ (ES = 0·04; P < 0·05). Children who achieved minimum diet diversity had higher HAZ (ES = 0·20; P < 0·05). Logistic regression models confirmed that exclusive breast-feeding was protective against wasting and DDI was protective against stunting and underweight.ConclusionsOur results highlight the importance of IYCF practices as determinants of child growth outcomes in this context, and reinforce the need for interventions that address the spectrum of IYCF practices, from exclusive breast-feeding to age-appropriate complementary feeding, especially diet diversity, in efforts to improve nutrition of infants and young children.
Sales effects of product health information at points of purchase: a systematic review
Authors: van 't Riet Jonathan 
Published: May 2012

AbstractObjectiveInformation about healthy and unhealthy nutrients is increasingly conveyed at the point of purchase. Many studies have investigated the effects of product health information on attitudes and intentions, but the empirical evidence becomes sketchier when the focus of research is actual purchase behaviour. The present paper provides an overview of empirical evidence on the effectiveness of product health information for food products at the point of purchase.DesignA systematic literature review was conducted.SettingOnly studies were included that assessed the effect of product health information at the point of purchase on actual purchase behaviour, using data provided by stores’ sales records or obtained by investigating customer receipts as the primary outcome measure.SubjectsThe included studies’ target group comprised supermarket clientele.ResultsSeveral studies found no significant effects of product health information on actual purchase behaviour. Interventions were more likely to be effective when they lasted for a longer time, when they included additional intervention components, and when they targeted the absence of unhealthy nutrients instead of or in addition to the presence of healthy nutrients.ConclusionsNo strong evidence for the effectiveness of product health information was found. The effect of intervention duration, additional promotional activities and targeting of healthyv. unhealthy nutrients should be closely examined in future studies.
Reversion from organic to conventional agriculture: A review

Published: May 2012

AbstractOver the past 10 years, the organic sector has expanded continuously in Europe due to policy support and a growing market demand for organic products. In line with this development, many farmers converted to organic farming each year. Nevertheless, the total number of organic farms has not increased constantly in Europe. In several countries, the absolute number of organic farms actually decreased in some years of the past decade. Some of the deregistered farmers gave up completely; others reverted to conventional agriculture. Against this background, this article aims (i) to give an overview of the extent of reversion to conventional agriculture in Europe based on statistics, (ii) to conceptualize the decision to revert in the form of a theoretical model, (iii) to compare farmers’ reasons to revert to conventional farming based on existing studies, and (iv) to identify further research needs. The importance of reversions to conventional agriculture is difficult to determine with the existing data, especially as in most cases it is not recorded as to what happened to the farms after deregistering from organic certification. The data nevertheless show that there are large fluctuations in the organic sector with many farmers entering and exiting each year. In order to reveal the farmers’ reasons for deregistering, various qualitative as well as quantitative surveys have been carried out already. For most farmers, the decision to revert is a result of different factors. Reasons for the reversion of their farms can be classified into economic motives, difficulties regarding certification and control, problems with organic production techniques as well as the farms’ macro environment. In most cases, however, economic reasons played a main role. Suggestions for organic legislation bodies, advisory services and policy makers are derived out of the findings. A deeper understanding of the influencing aspects regarding reversions and the necessary changes in the organic sector to avoid them should be an important objective of forthcoming research.
Comparison of crop management strategies involving crop genotype and weed management practices in conventional and more diverse cropping systems

Published: May 2012

AbstractCropping systems that include forage legumes and small grains in addition to corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] can achieve similar or higher crop productivity and economic return than simpler corn–soybean rotations. We hypothesized that this rotation effect occurs regardless of the crop genotype planted and the herbicide and cultivation regime selected for weed management. To test this hypothesis, we conducted a 3-year experiment that compared three cropping systems: a conventional 2-year corn–soybean rotation, a 3-year corn–soybean–oat (Avena sativa L.)/red clover (Trifolium pretense L.) rotation, and a 4-year corn–soybean–oat/alfalfa–alfalfa (Medicago sativa L.) rotation. Within each cropping system, two contrasting sets of management strategies were used: (i) genetically engineered corn with resistance to insect pests (Ostrinia nubilalis Hübner and Diabrotica spp.) plus the broadcast application of pre-emergence herbicides, followed in the rotation by a genetically engineered soybean variety with resistance to the herbicide glyphosate plus the post-emergence broadcast application of glyphosate; and (ii) non-genetically engineered corn plus the banded application of post-emergence herbicides, followed in the rotation by a non-genetically engineered soybean and banded application of several post-emergence herbicides. The two management strategies were identified as ‘GE’ and ‘non-GE.’ Corn yield was higher in the 3-year (12.51Mgha−1) and 4-year (12.79Mgha−1) rotations than in the conventional 2-year (12.16Mgha−1) rotation, and was also 2% higher with the GE strategy than with the non-GE strategy. Soybean yield was similar among rotation systems in 2008, but higher in the 3- and 4-year systems than the 2-year rotation in 2009 and 2010. Soybean yield was similar between management strategies in 2008, but higher in the GE strategy in 2009, and similar between strategies in the 3- and 4-year rotations in 2010. Increases in rotation length were accompanied by 88–91% reductions in synthetic N fertilizer application, and the use of the non-GE rather than the GE strategy was accompanied by a 93% reduction in herbicide active ingredients applied. Averaged over the period of 2008–2010, net returns to land and labor were highest for the 3-year rotation managed with either the GE ($928ha−1yr−1) or non-GE ($936ha−1yr−1) strategies, least in the 2-year rotation managed with the non-GE strategy ($738ha−1yr−1), and intermediate in the other rotation×management combinations. Our results indicate that more diverse crop rotation systems can be as profitable as conventional corn–soybean systems and can provide farmers with greater flexibility in crop management options.
What's therapeutic about the therapeutic relationship? A hypothesis for practice informed by Perceptual Control Theory
Authors: Carey Timothy A. , Kelly Rebecca E. , Mansell Warren , Tai Sara J. 
Published: May 2012

AbstractEvidence clearly suggests that the therapeutic relationship is important to successful outcomes in psychotherapy. It is less clear as to why this might be the case. Throughout the literature, various factors such as warmth, empathy, compassion, unconditional positive regard, and openness are identified as key. The way in which factors such as warmth and empathy bring about an amelioration of psychological distress, however, is not entirely obvious. We suggest that one possible mechanism through which these factors become important is by helping to create an environment where clients can examine their problems freely. Furthermore, we propose that when the therapeutic relationship is therapeutic, clients feel comfortable to consider whatever comes into their mind; with any filtering or evaluating happening after the ideas have been expressed, and not before. Psychological processes identified as maintaining psychological distress (e.g. thought suppression, avoidance, rumination) block this capacity. Our suggestion is that as internal experiences are being examined, the client has an opportunity to become aware of facets of the problem that were previously unattended to; and to continue this process outside therapy. Through this awareness-raising process the client's problem can be reorganized via intrinsic learning processes to achieve a more contented state of mind.
Analysis of totem-pole drivers in SiGe for RF and wideband applications
Authors: Wickert Michael , Wolf Robert , Ellinger Frank 
Published: May 2012

This paper presents an analysis of totem-pole (TP) stages for driver applications and summarizes the major design constraints for an optimization with respect to P1dB, OIP3, and bandwidth. It is shown, that for matched drivers, in contrast to the widely applied common collector (CC) stage, class-AB TP stages offer higher output power and much higher power-added efficiencies (PAE) at comparable bandwidth. A combiner chip in 0.25 μm SiGe Bipolar CMOS (BiCMOS) verifying this concept in hardware as output driver is demonstrated proofing the increased achievable output power, which was measured greater than +0.1 dBm. This is approximately 11 dB higher than for a conventional CC driver. Furthermore, a concept is proposed, where the TP stage can act as a broadband matched driver for differential or balun operation ranging down to DC. As verification a broadband driver design using a class-AB TP stage is presented, which has a 3 dB bandwidth of 7.9 GHz and delivers up to +4.3 dBm into a 50 Ω load, which is 17 dB higher than its CC counterpart. At this output power it consumes a DC power of 12.3 mW and yields a PAE of 16.1%.
Causes for decadal variations of wind speed over land: Sensitivity studies with a global climate model
Authors: Bichet A. , Wild M. , Folini D. , Schär C. 
Published: May 2012

Over the past 30 years, observations indicate a decline of about −0.3 m/s in the northern mid‐latitudes land surface wind speed. The picture is less conclusive for the Southern Hemisphere and over the oceans. Such a stilling can affect surface evaporation and climate feedback processes, and may impact technical applications such as wind power. Using an atmospheric global climate model, we perform sensitivity experiments for the period 1870–2005 to assess the role of changing roughness length, aerosol emissions, sea surface temperature, and greenhouse gas concentrations in surface wind speed changes. The wind speed trends simulated by the model generally underestimate the observed trends (land and ocean). Over land, the model can reproduce the observed stilling by increasing the roughness length by a factor of 1.2 to 4.9, depending on region. The other forcings examined can also decrease the 10 m wind speeds (up to 15% of observed values in Europe), particularly those related to increasing aerosol emissions (up to −0.2 m/s in India). Compared to observations, the simulated impact of climate forcings on global wind speeds over land and ocean is however small and not always significant.
Visible light generation of I–I bonds by Ru-tris(diimine) excited states
Authors: Farnum Byron H. , Jou Jeffrey J. , Meyer Gerald J. 
Published: May 2012

Seven Ru-tris(diimine) compounds were prepared to study the photooxidation of iodide. Iodide oxidation results in the formation of I–I bonds, and it is therefore relevant to the conversion and storage of solar energy. Iodide oxidation is also a key step for electrical power generation in dye-sensitized solar cells. The mechanistic details of iodide oxidation and I–I bond formation were elucidated through time-resolved spectroscopic measurements. Bimolecular electron-transfer reactions between Ru-tris(diimine) excited states and iodide first yielded the iodine atom that subsequently reacted with excess I

). An important finding was that excited-state iodide oxidation was rapid (

Gray Mold of Green Shiso (Perilla frutescens), Caused by Botrytis cinerea, in California
Authors: Koike S. T. , Daugovish O. 
Published: May 2012

Shiso (Perilla frutescens) is a leafy herb in the Lamiaceae family and is widely used in Japanese and other Asian cuisine for cooking, pickling, oil (from the seeds), and garnish. A number of shiso types are used, though the most common are green shiso (ao-shiso) and red shiso (aka-shiso). In the winter months of 2010 and early spring 2011, a foliar blight disease developed on greenhouse-grown green shiso produced in Ventura County, CA. Initial symptoms were angular, dull green leaf lesions on older foliage. Such lesions often were initiated along leaf edges. As the disease progressed, lesions turned gray green, expanded, and could affect most of the leaf surface. Lesion tissue became dry and papery in texture; signs of a pathogen were not present. Tests for bacterial agents were negative. However, a fungus was consistently isolated from symptomatic leaves. Isolates of this fungus were grown on potato dextrose agar (PDA) in petri plates incubated under fluorescent lights and were identified as Botrytis cinerea (1). On PDA, mycelial growth was gray brown and conidiophores measured 2 mm or longer and were branched at the terminals. Conidia were aseptate, hyaline, ellipsoidal, and measured (6.5–) 8.4 to 9.2 (–12.0) × (6.1–) 6.8 to 8.0 (–9.5) μm. Sclerotia were not present. Pathogenicity of four isolates was tested by spraying conidial suspensions (1 × 105 conidia/ml) until runoff onto sets of potted green and red shiso plants. Each set consisted of six wounded (leaf tips cut) and six unwounded plants. Plants were enclosed in plastic bags for 48 h and then maintained at 22 to 24°C in a greenhouse. After 4 days, leaf lesions developed on both wounded and unwounded leaves of green and red shiso. The resulting symptoms were similar to those observed in commercial production and B. cinerea was recovered from symptomatic tissue. Non-inoculated, wounded, and unwounded red and green shiso plants were sprayed with distilled water and did not develop symptoms. This experiment was conducted two times and results were the same. To our knowledge, this is the first report of gray mold of shiso in the United States caused by B. cinerea. The disease caused significant damage to the shiso crop because symptomatic leaves are unacceptable for market. In 2010, the greenhouse facility that contained the diseased shiso had numerous leaks in the roof; winter rains that occurred during this time therefore resulted in higher free moisture and humidity in the growing area, which likely provided optimum environmental conditions for the pathogen to infect and cause disease on shiso.
