“Little Quilted Vests to Warm Parents' Hearts”: Redefining the Gendered Practice of Filial Piety in Rural North-eastern China
Authors: Shi Lihong 
Published: June 2009

AbstractThis article explores the transformation of the gendered practice of filial piety in China, which traditionally places sons at the centre and relegates daughters to a peripheral role within their natal families. Based on my ethnographic fieldwork in a rural community in north-eastern China, this article suggests a transformed opinion on filial piety, considering daughters as more filial, as is vividly expressed by the Chinese saying “A daughter is like a little quilted vest to warm her parents' hearts.” Meanwhile, elderly parents have modified traditional standards of filial practice to encompass a desire for an expression of intimate care, respect and practical support from adult children. Further examination suggests three major factors contributing to the transformation of the gendered practice of filial piety: reinterpreted intergenerational relations, women's increased filial practice to their natal parents, and an increased desire of the elderly for an emotional bond with their children.
Environmental Activism, Social Networks and the Internet
Authors: Sullivan Jonathan , Xie Lei 
Published: June 2009

AbstractSocial networks and the internet both have a substantial individual effect on environmental activism in China. In this article, we speculate that social linking patterns between environmental actors, which often facilitate activism on the ground, may also exist in cyberspace in the form of an online network. The article addresses the following empirical questions. Does such an online network exist? If so, who are the constituent actors? Are these the same actors observed on the ground? In addressing these questions the article aims to contribute to the growing debate on the implications of the internet for the potential emergence of social movements in China.

Published: June 2009

This paper presents a technique that enables both efficiency and linearity enhancements of power amplifiers (PA) used in communication systems. It consists in the implementation of a dynamic bias control combined with digital base-band predistortion. The aim of this paper is to describe a methodology and successive steps of the design procedure to reach optimum performances in terms of power added efficiency (PAE) and linearity. It is here applied to a 100 W wide-band lateral diffused metal oxide semiconductor (LDMOS) push–pull amplifier (50–500 MHz) driven by orthogonal frequency division multiplexing (OFDM) signals. When the amplifier is driven by a continuous wave (CW) signal and operates at a constant 28 V drain bias voltage, it exhibits 100 W output power and 60% PAE. When it is driven by an OFDM signal, a 10 dB output power back-off is necessary to have a −25 dBc adjacent channel power ratio (ACPR) and PAE decreases down to 10%. By properly implementing an envelope tracking bias system, 40 W output power along with 38% PAE and −27 dBc ACPR have been reached. Applying base-band digital predistortion provides additional linearity improvements at high PAE (for only one point PAE lost, a 5 dB improvement is obtained for ACPR).
Digitally assisted equalization of third-order intermodulation products in wideband direct conversion receivers
Authors: Keehr Edward A. , Hajimiri Ali 
Published: June 2009

An effective linearization technique capable of equalizing IM3 products resulting from an arbitrary out-of-band blocking scenario in a wideband direct conversion receiver is presented. IM3 products are regenerated in the RF analog domain of a low-power mixed-signal feedforward path and are used to cancel analogous signal terms in the original receiver at digital baseband via adaptive equalization. The composite SAW-less receiver achieves an improvement in effective IIP3 from −7.1 to +5.3 dBm under worst-case UMTS Region 1 blocking when the feedforward path is active.
Neglektdyslexie – Ätiologie, Diagnostik und Therapie einer vernachlässigten Störung
Authors: Heidler Maria-Dorothea 
Published: June 2009

Die Neglektdyslexie ist alltagsrelevante Folge eines Neglekts, in der Forschung und bei der Entwicklung effektiver Behandlungsmethoden jedoch stark unterrepräsentiert.Typische Fehler sind Omissionen, Substitutionen und Additionen von Wörtern und Buchstaben in der kontraläsionalen Raumhälfte mit resultierender Beeinträchtigung des Lesesinnverständnisses. Häufigste Ursache sind Läsionen des rechten Parietallappens – oft mit Ausdehnung in den Okzipital- und Temporallappenbereich.Anhand des 3-Stufen-Modells der visuellen Wortrekognition von Caramazza & Hillis (1990) können Neglektdyslexien unterteilt werden in spatiale (stimuluszentrierte) und positionale (wortzentrierte) Formen.Bislang existieren keine störungsspezifischen Programme zur Therapie der Neglektdyslexie, so dass Übungen zur Behandlung von zentralen, hemianopen und Entwicklungsdyslexien adaptiert werden müssen. Dabei müssen neglektspezifische Phänomene (wie Anosognosie, fehlender Leidensdruck, Konfabulationsneigung oder ein geringer selbständiger Transfer) berücksichtigt werden.
Zur Versorgungssituation im Bereich der ambulanten neuropsychologischen Therapie – eine bundesweite Totalerhebung
Authors: Mühlig Stephan , Rother Aline , Neumann-Thiele Anja , Scheurich Armin 
Published: June 2009

Hintergrund: In Deutschland wird die Anzahl von Patienten mit Indikation für eine ambulante neuropsychologische Therapie auf jährlich ca. 40.000 – 60.000 geschätzt. Dem stehen bundesweit lediglich ca. 200 ambulant tätige Psychologische Psychotherapeuten (PPT) mit neuropsychologischer Qualifikation gegenüber. Ziele und Fragestellungen: Welche Patienten mit welchen Merkmalen und Störungsbildern werden von neuropsychologischen PPT mit welchen Charakteristika wie, in welchen Settings, wie lange und mit welchem Erfolg behandelt? Methodik und Design: Totalerhebung aller ambulanten neuropsychologischen Therapeuten in Deutschland (GNP-Register) mittels Fragebogen zu fünf Themenbereichen: 1) Therapeutencharakteristika, 2) Praxismerkmale, 3) Patientencharakteristika, 4) strukturelle Bedingungen, 5) Überweisungsprozesse. Stichprobe: Auswertungsstichprobe N=118 (Ausschöpfungsquote: 65 %). Ergebnisse: Die Versorgungsdichte bezogen auf die Bevölkerungszahl beträgt ca. 1:360.000 (West-Ost-Vergleich 3:1). Neuropsychologische Therapeuten besitzen i.d.R die Approbation als PPT und behandeln zu 70 % neuropsychologisch erkrankte Patienten mit einer Kombination aus neuropsychologischen Interventionsmethoden und sonstigen Richtlinienverfahren. Die häufigsten Ursachen neuropsychologischer Störungsbilder sind Schädel-Hirn-Traumata und cerebrovaskuläre Erkrankungen, die dominierenden Funktionsstörungen liegen im Bereich Aufmerksamkeit, Konzentration und Affektivität. Die überwiegende Mehrheit der Patienten mit einer neuropsychologischen Störung weist eine psychische Komorbidität auf. In der Selbstbeurteilung der Therapeuten werden die Therapieziele zu etwa zwei Dritteln erreicht. Conclusio: Um die Versorgungslage zu verbessern, muss die ambulante neuropsychologische Psychotherapie sozialrechtlich besser geregelt sowie die Ausbildungskapazität deutlich erhöht werden.
Journals and repositories: an evolving relationship?
Authors: PINFIELD Stephen 
Published: June 2009

ABSTRACTIt is now widely accepted that there are two routes to open access (OA): OA repositories and OA journals. It is often assumed these are distinct alternative parallel tracks. However, it has recently become clear that there is potential for repositories and journals to interact with each other on an ongoing basis and between them to form a coherent OA scholarly communication system. This paper puts forward three possible models of interaction between repositories and journals; services such as arXiv and PubMed Central, and the work carried out by the RIOJA project, are working exemplars and pilot implementations of these models. The key issues associated with the widespread adoption of these models include repository infrastructure development; changing ideas of the ‘journal’, ‘article’, and ‘publication’; version management; quality assurance; business and funding models; developing value‐added features; content preservation; policy frameworks; and changing roles and cultures within the research community.
Scholarly publishing and open access in the Nordic countries
Authors: HEDLUND Turid , RABOW Ingegerd 
Published: June 2009

ABSTRACTThis study examines aspects of scholarly journal publishing in the Nordic countries. On average half of Nordic journals publish online. In most Nordic countries, commercial publishers predominate; however, in Finland the majority are society publishers. The number of open access journals is low, in line with international figures. There is concern to maintain local languages in journal publishing. A majority of the journals publishing in local languages are within social science, humanities, and arts; the STM sector publishes in English. English‐language publications are favoured in research assessments, international recognition, and impact, while the visibility of local‐language scholarly journals in international databases is low. The Nordbib program supports Nordic scholarly journals and fosters co‐operation with publishing companies and learned societies over migration to e‐publishing; it also supports open access. The article discusses future challenges for journal publishing, pointing out the problems of small journal publishers and the need for co‐operation between stakeholders.
A different form of editor—author interaction: the approach of university journals in China
Authors: LI Li 
Published: June 2009

ABSTRACTUniversity journals in China exist primarily to showcase the academic research achievements of the university from which they originate. Although they do publish peer‐reviewed articles, their management, distribution, and editorial processes are different from those of regular academic journals. Because they are on campus, the editors of university journals can use face‐to‐face communication to help their authors to revise their papers. To maximize the efficiency of this communication, editors need to prepare well before giving such guidance in order to minimize publication delay, to provide useful guidance to groups of authors, and to improve their own editorial abilities and knowledge.
Creating the Mark Twain Project Online
Authors: SCHIFF Lisa 
Published: June 2009

ABSTRACTThe Mark Twain Project Online (MTPO) was launched in October 2007 and, in this first phase, digitally published several thousand of Twain's letters, almost 100 facsimiles of original documents, and over 28,000 records of other correspondence. The partners involved in the building of MTPO – the Mark Twain Papers, the California Digital Library, and University of California Press – created the site on the premise that Web‐accessible versions of this content, enhanced by innovative design and site architecture and a suite of research tools, would greatly improve scholars' ability to discover and work with this unique material. Anecdotal feedback supports this premise. Early data analysis confirms the usefulness of facsimiles and browsing functionality. Users tend to prefer simple keyword over complex searches; however, those conducting advanced searches are using the tool flexibly, as we had hoped. Further analysis is expected to improve our understanding of how researchers use these tools in combination.

What societies want from a publishing partner
Authors: ASHMAN Peter 
Published: June 2009

ABSTRACTSocieties, whose publishing programmes are primarily mission‐driven, play a unique role in funding and disseminating research. But by their nature – often small and with limited resources – they are particularly prone to the turbulence currently affecting scholarly publishing. BMJ Journals is itself a society publisher but also publishes under contract for other societies. During 2008, we carried out research to assess societies' evolving needs from their publishing partnerships. The changing expectations and behaviours of the next generation of researchers are considered to be as much of a threat as declining revenues. Societies are planning to expand professional development activities and to maximise their use of emerging technologies to help maintain and grow membership. Although surplus is a low priority for societies and, accordingly, for their publishing programmes, a high financial return is nonetheless a key criterion when choosing publishing partners – as are reputation, technological innovation, and individual title development.
Learned society members and open access
Authors: MORRIS Sally , THORN Sue 
Published: June 2009

ABSTRACTThe individual members of 35 UK learned societies were surveyed on their attitudes to open access (OA); 1,368 responses were received. Most respondents said they knew what OA was, and supported the idea of OA journals. However, although 60% said that they read OA journals and 25% that they published in them, in both cases around one‐third of the journals named were not OA. While many were in favour of increased access through OA journals, concerns were expressed about the cost to authors, possible reduction in quality, and negative impact on existing journals, publishers, and societies. By contrast, less than half knew what self‐archiving was; 36% thought it was a good idea and 50% were unsure. Just under half said they used repositories of self‐archived articles, but 13% of references were not in fact to self‐archiving repositories. 29% said they self‐archived their own articles, but 10% of references were not to publicly accessible sites of any kind. The access and convenience of self‐archiving repositories were seen as positive, but there were concerns about quality control, workload for authors and institutions, chaotic proliferation of versions, and potential damage to existing journals, publishers, and societies.

Published: June 2009

ABSTRACTObjective:Studies in adults characterized the role of the pregnane X receptor (PXR) in the pathophysiology of inflammatory bowel disease (IBD) with conflicting results; pediatric studies are still lacking.Patients and Methods:Genotyping for the −25385C/T polymorphism of the PXR gene in 187 white children with IBD and 185 controls. Determination of colonic PXR expression in selected patients with IBD.Results:Minor allele frequency was seen in 35.6% patients with IBD and 40.5% controls (P = 0.174), although no significant differences were seen between the genotypes (P = 0.366). PXR was underexpressed in colonic tissue of 7 out of 11 Crohn disease and in 4 out of 5 patients with ulcerative colitis.Conclusions:We could not confirm an association of the −25385C/T polymorphism in pediatric patients with IBD.
Defensins Are Differentially Expressed With Respect to the Anatomic Region in the Upper Gastrointestinal Tract of Children
Authors: Vordenbäumen Stefan , Pilic Denisa , Otte Jan‐Michel , Schmitz Frank , Schmidt‐Choudhury Anjona 
Published: June 2009

ABSTRACTDefensins are antimicrobial peptides expressed on various epithelial surfaces. Although they are believed to contribute to intestinal homeostasis, their expression pattern in children is not well characterized. As determined by real‐time polymerase chain reaction, amount of human alpha‐defensins (hD)‐5 and ‐6 mRNA in duodenal biopsies were significantly higher than in biopsies taken from the gastric mucosa. On the contrary, expression of human beta‐defensins (hBD)‐1 and ‐2 mRNA showed a significantly higher expression in the stomach. Expression of hBD3 to 6 was inconsistently detected. These results suggest a distinct role for various defensins in host defense in the upper gastrointestinal tract of children.

Published: June 2009

ABSTRACTObjectives:The purpose of the present study was to evaluate the effects of exogenous bilirubin on structural intestinal adaptation, cell proliferation, and apoptosis in a rat model of short bowel syndrome (SBS).Materials and Methods:Male Sprague‐Dawley rats were divided into 5 experimental groups: Sham rats underwent bowel transection and reanastomosis, sham multiple doses of bilirubin (MDB) rats underwent bowel transection and were treated with bilirubin, SBS rats underwent a 75% small bowel resection, SBS‐SDB (single dose bilirubin) rats underwent a bowel resection and were treated with a single dose of bilirubin, and SBS‐MDB underwent a bowel resection and were treated with 3 doses of bilirubin. Bilirubin was administered intraperitoneally from the 7th day through the 14th day postoperatively. Serum total bilirubin concentration over time was evaluated in 5 SBS‐SDB rats following a single intraperitoneal dose. Total bilirubin, alanine aminotransferase, and aspartate aminotransferase in serum and parameters of intestinal adaptation, enterocyte proliferation, and enterocyte apoptosis were determined on day 15.Results:SBS‐SDB and SBS‐MDB animals demonstrated lower ileal bowel and mucosal weights, jejunal mucosal DNA and ileal mucosal protein, and jejunal and ileal villus height and crypt depth (vs SBS animals). Bilirubin‐treated rats showed a lower apoptotic index in jejunum and ileum and a trend toward an increase in cell proliferation in jejunum and ileum (vs SBS group).Conclusions:In a rat model of SBS, exogenous bilirubin inhibits structural intestinal adaptation. Increased cell proliferation and decreased apoptosis may be considered adaptive mechanisms that maintain cell mass.
BT2, a BTB Protein, Mediates Multiple Responses to Nutrients, Stresses, and Hormones in Arabidopsis
Authors: Mandadi Kranthi K. , Misra Anjali , Ren Shuxin , McKnight Thomas D. 
Published: June 2009

AbstractThe Arabidopsis (Arabidopsis thaliana) gene BT2 encodes a 41-kD protein that possesses an amino-terminal BTB domain, a central TAZ domain, and a carboxyl-terminal calmodulin-binding domain. We previously demonstrated that BT2 could activate telomerase expression in mature Arabidopsis leaves. Here, we report its distinct role in mediating diverse hormone, stress, and metabolic responses. We serendipitously discovered that steady-state expression of BT2 mRNA was regulated diurnally and controlled by the circadian clock, with maximum expression in the dark. This pattern of expression suggested that BT2 mRNA could be linked to the availability of photosynthate in the plant. Exogenous sugars decreased BT2 expression, whereas exogenous nitrogen increased expression. bt2 loss-of-function mutants displayed a hypersensitive response to both sugar-mediated inhibition of germination and abscisic acid (ABA)-mediated inhibition of germination, thus supporting a role of ABA in sugar signaling in germination and development. Moreover, constitutive expression of BT2 imparted resistance to both sugars and ABA at germination, suggesting that BT2 suppresses sugar and ABA responses. In support of the previously described antagonistic relationship between ABA and auxin, we found that BT2 positively regulated certain auxin responses in plants, as revealed by knocking down BT2 expression in the high-auxin mutant yucca. Accumulation of BT2 mRNA was affected by a variety of hormones, nutrients, and stresses, and BT2 was required for responses to many of these same factors. Together, these results suggest that BT2 is a central component of an interconnected signaling network that detects and responds to multiple inputs.
Resistance to the Pseudomonas syringae Effector HopA1 Is Governed by the TIR-NBS-LRR Protein RPS6 and Is Enhanced by Mutations in SRFR1

Published: June 2009

Abstract
The Pseudomonas syringae-Arabidopsis (Arabidopsis thaliana) interaction is an extensively studied plant-pathogen system. Arabidopsis possesses approximately 150 putative resistance genes encoding nucleotide binding site (NBS) and leucine-rich repeat (LRR) domain-containing proteins. The majority of these belong to the Toll/Interleukin-1 receptor (TIR)-NBS-LRR (TNL) class. Comparative studies with the coiled-coil-NBS-LRR genes RPS2, RPM1, and RPS5 and isogenic P. syringae strains expressing single corresponding avirulence genes have been particularly fruitful in dissecting specific and common resistance signaling components. However, the major TNL class is represented by a single known P. syringae resistance gene, RPS4. We previously identified hopA1 from P. syringae pv syringae strain 61 as an avirulence gene that signals through ENHANCED DISEASE SUSCEPTIBILITY1, indicating that the corresponding resistance gene RPS6 belongs to the TNL class. Here we report the identification of RPS6 based on a forward-genetic screen and map-based cloning. Among resistance proteins of known function, the deduced amino acid sequence of RPS6 shows highest similarity to the TNL resistance protein RAC1 that determines resistance to the oomycete pathogen Albugo candida. Similar to RPS4 and other TNL genes, RPS6 generates alternatively spliced transcripts, although the alternative transcript structures are RPS6 specific. We previously characterized SRFR1 as a negative regulator of avrRps4-triggered immunity. Interestingly, mutations in SRFR1 also enhanced HopA1-triggered immunity in rps6 mutants. In conclusion, the cloning of RPS6 and comparisons with RPS4 will contribute to a closer dissection of the TNL resistance pathway in Arabidopsis.
