Published: June 2008

AbstractThe flowering characteristics of a highly inbreeding species such as barley might influence the extent of outcrossing that can be expected. Increased outcrossing is a prerequisite to exploit heterosis in inbreeding species, which can lead to considerable yield increase as has been demonstrated for barley grown under marginal conditions. Anther extrusion (AE) in barley has been demonstrated to be a genetically controlled, quantitative trait with intermediate to high heritability. Some authors consider AE and open flowering in barley as identical. The present study was conducted to investigate whether barley genotypes with increased AE exhibit increased outcrossing rates under field conditions in comparison with genotypes showing no AE. Field experiments were conducted in three contrasting environments in Jordan in the 2001/02 growing season using six adapted barley genotypes, three with high AE and three with no AE. Outcrossing rates were investigated employing codominant DNA markers (microsatellites). No significant difference in outcrossing rates was detected between anther‐extruding and non‐extruding barley genotypes. Results indicate that high AE is not a sufficient condition to cause increased outcrossing rates and thus cannot be termed open flowering.
Effect of upper limb botulinum toxin‐A therapy on health‐related quality of life in children with hemiplegic cerebral palsy
Authors: Redman Toni A , Finn Judith C , Bremner Alexandra P , Valentine Jane 
Published: June 2008

Aim: Currently, the use of upper limb botulinum toxin‐A (UL BTX‐A) is based on evidence of functional efficacy without supporting evidence of positive change in health‐related quality of life (HRQOL). While function may improve, this cannot be directly correlated with an improvement in HRQOL. Most paediatric studies use caregiver/parent proxy reports. The inclusion of child self‐reports is increasing as poor correlation with proxy reports is being demonstrated. This paper aims to study the effect of UL BTX‐A therapy on HRQOL in children with hemiplegic cerebral palsy (CP).Method: Design: Pilot prospective randomised trial. Participants: 22 children with hemiplegic CP aged 7 years 0 month−13 years 11 months (12 treatment, 10 control). Treatment: One series BTX‐A injections into UL. HRQOL assessed at baseline, and 1, 3 and 6 months post‐injection by completion of Pediatric Quality of Life (PedsQL) 4.0 Generic Core Scales and PedsQL 3.0 CP Module. Outcome: 1. Change in PedsQL scores. 2. Concordance between child self‐report and parent proxy‐report scores.Results: No statistically significant difference between treatment and control groups was observed for any domain of HRQOL. Intraclass concordance was good for the PedsQL CP Module Daily Activities, and Speech and Communication scores (P = 0.0005).Conclusion: This pilot work adds to the emerging evidence that UL BTX‐A therapy has no statistically significant effect on the HRQOL of children with hemiplegic CP. With the increasing use of this therapy in children with CP, further research across the broader CP population is needed to identify whether this therapy is indicated in other target populations. Both child and parent proxy reports should be collected when assessing HRQOL in this population.
Clinical presentation and prognosis of childhood Guillain–Barré syndrome
Authors: Lee Jung Hwan , Sung In Young , Rew Il Sun 
Published: June 2008

Aim:  Guillain–Barré syndrome (GBS) is an acute inflammatory polyneuropathy commonly characterised by rapidly progressive, symmetric weakness and areflexia. This study is to assess the clinical characteristics of paediatric GBS, as well as its long‐term functional prognosis.Methods:  We retrospectively assessed the clinical manifestations, results of electrodiagnostic tests, functional status and prognosis of 56 children diagnosed with GBS. Based on clinical and electrophysiological findings, the patients were classified as having acute inflammatory demyelinating polyradiculoneuropathy ([AIDP]n = 34), acute motor axonal neuropathy ([AMAN]n = 14), acute motor and sensory axonal neuropathy (n = 1) and Miller Fisher syndrome ([MFS]n = 7).Results:  Upper respiratory infection was the most frequent preceding event, and limb weakness was the most frequent symptom at GBS onset. There was no significant difference in the mean time from the onset of illness to nadir between any of these groups. Both the AIDP and AMAN groups showed significantly poorer functional status, measured by the Hughes scale, than the MFS group. Two years after nadir, however, the three groups did not differ significantly. Functional status at nadir, as estimated by the Hughes scale, is a more important factor than electrophysiological types in predicting long‐term outcome.Conclusion:  The most common symptom at onset in paediatric GBS was limb weakness. Functional status at nadir in AMAN was not significantly different from that of AIDP, and both types achieved good functional outcome for ambulation after 2 years. Functional status at nadir was more important than the electrophysiological type in predicting long‐term outcomes.
How useful is knemometry in measuring neonatal growth?
Authors: Dixon Bronwyn , Darlow Brian , Prickett Timothy 
Published: June 2008

Background:  Knemometry has been used to accurately measure linear growth in both neonates and children over the last 20 years. It has been used principally as a research tool.Aim:  To investigate whether serial measurement of lower leg length (LLL) by knemometry is a useful addition to other measures of growth in the neonatal unit.Methods:  A 1‐year prospective hospital‐based cohort study from 2004 to 2005. Knemometry was performed every 3–4 days from the time of consent to time of discharge. Infants were grouped by gestation at birth for analysis (<28 weeks, 28–31 weeks, 32–36 weeks and >36 weeks gestation). The main outcome assessed was longitudinal growth. Subgroup analyses were performed on infants <10th percentile for weight, surgical infants and infants who had received antenatal steroids.Results:  LLL measured by knemometry correlated well with postmenstrual age (r = 0.93) and weight (r = 0.93). The mean (SD) increase in LLL was 0.45 (0.7) mm/day.Conclusion:  Change in LLL correlates well with change in weight and postmenstrual age in the neonatal period but adds little extra information to routine practice in the neonatal unit.
Activity and identity of fermenting microorganisms in full‐scale biological nutrient removing wastewater treatment plants
Authors: Kong Yunhong , Xia Yun , Nielsen Per Halkjær 
Published: June 2008

SummaryHydrolysis and fermentation are of key importance in biological nutrient removal (BNR) wastewater treatment plants as they provide polyphosphate‐accumulating organisms and denitrifying bacteria with carbon and energy sources (e.g. short chain fatty acids). Little information, however, exists about the microbiology of the microorganisms involved in hydrolysis and fermentation. In this study, fermentation of monosaccharides was found to be a universal process taking place in all full‐scale BNR plants investigated, where glucose and other monosaccharides were consumed and fermented during anaerobic conditions. The removal rates of glucose were in the range of 0.05–0.32 mmol gVSS−1 h−1 and only slightly lower than glucose removal under aerobic conditions. The main fermentation products detected were (in descending order) propionic acid, lactic acid, acetic acid and formic acid. The fermentation was diverse, consisting of at least three fermentation metabolisms, including lactic acid (homolactic), mixed acid and propionic acid fermentations. Possible existence of alcohol and/or butyric acid fermentations could not be excluded. Fermentation organisms in Aalborg East treatment plant were identified by using microautoradiography combined with fluorescence in situ hybridization. All microorganisms involved in monosaccharide fermentation belonged to either Gram‐positive Firmicutes or Actinobacteria. Most of them were related either to Streptococcus, hybridizing to the oligonucleotide probe Str, or to uncultured Actinobacteria with a phenotype of polyphosphate‐accumulating organisms. The fermenting bacteria were widespread in the nine full‐scale BNR plants investigated and constituted 3–21% of the total bacterial biovolume.

SummaryWe collected surface samples in Franklin Bay (Western Arctic) from ice‐covered to ice‐free conditions, to determine seasonal changes in the identity and in situ activity of the prokaryotic assemblages. Catalysed reported fluorescence in situ hybridization was used to quantify the abundance of different groups, and combined with microautoradiography to determine the fraction of active cells taking up three substrates: glucose, amino acids and ATP. In surface waters, Archaea accounted for 16% of the total cell count in winter, but decreased to almost undetectable levels in summer, when Bacteria made up 97% of the total cell count. Alphaproteobacteria were the most abundant group followed by Bacteroidetes (average of 34% and 14% of total cell counts respectively). Some bacterial groups appearing in low abundances (< 10% of total cell counts), such as Betaproteobacteria, Roseobacter and Gammaproteobacteria, showed a high percentage of active cells. By contrast, more abundant groups, such as SAR11 or Bacteroidetes, had a lower percentage of active cells in the uptake of the substrates tested. Archaea showed low heterotrophic activity throughout the year. In comparison with temperate oceans, the percentage of active Bacteria in the uptake of the substrates was relatively high, even during the winter season.

SummaryWe designed and tested a set of specific primers for specific PCR amplification of the biotin carboxylase subunit gene (accC) of the Acetyl CoA carboxylase (ACCase) enzyme. The primer set yielded a PCR product of c. 460 bp that was suitable for denaturing gradient gel electrophoresis (DGGE) fingerprinting followed by direct sequencing of excised DGGE bands and sequence analysis. Optimization of PCR conditions for selective amplification was carried out with pure cultures of different bacteria and archaea, and laboratory enrichments. Next, fingerprinting comparisons were done in several aerobic and anaerobic freshwater planktonic samples. The DGGE fingerprints showed between 2 and 19 bands in the different samples, and the primer set provided specific amplification in both pure cultures and natural samples. Most of the samples had sequences grouped with bacterial accC, hypothetically related to the anaplerotic fixation of inorganic carbon. Some other samples, however, yielded accC gene sequences that clustered with Crenarchaeota and were related to the 3‐hydroxypropionate/4‐hydroxybutyrate cycle of autotrophic crenarchaeota. Such samples came from oligotrophic high mountain lakes and the hypolimnia of a sulfide‐rich lake, where crenarchaeotal populations had been previously reported by 16S rRNA surveys. This study provided a fast tool to look for presence of accC genes in natural environments as potential marker for studies of carbon dioxide assimilation in the dark. After further refinement for better specificity against archaea, the new and novel primers could be very helpful to establish a target for crenarchaeota with implications for our understanding of archaeal carbon biogeochemistry.
How Lay Third Parties Weigh Legitimacy and Sanctions in a Side‐Taking Dilemma: A Study among Chinese and Dutch Employees
Authors: Yang Huadong , Van de Vliert Evert , Shi Kan 
Published: June 2008

Lay third parties sometimes react to an interpersonal dispute by taking sides. In this paper, we investigate the interaction effects of lay third parties’ moral and expedient orientations on the relationship between perceived legitimacy (or expected negative sanctions) and their intention of side‐taking with a legitimacy party (or a sanction party). Seventy‐nine Chinese and 77 Dutch employees were presented with a scenario describing a conflict dilemma between one party who has more legitimacy claims but less negative sanctions and the other party who has less legitimacy claims but more negative sanctions. The results showed that moral orientation by itself has a reinforcing effect on the positive link between perceived legitimacy and siding with a legitimacy party. In addition, in both countries, the relationship between expected negative sanctions and side‐taking with a sanction party was moderated by a joint effect of the moral and the expedient orientations. That is, for lay third parties with a weakly moral orientation and a strongly expedient orientation, an increase in negative sanctions led to more side‐taking with a sanction party. For those lay third parties who were weakly moral and weakly expedient oriented, strongly moral and strongly expedient oriented, or strongly moral and weakly expedient oriented, the above‐mentioned link was not positive any more.Confrontés à un conflit interpersonnel, les tiers non concernés réagissent parfois en prenant parti. Dans cet article, nous étudions les effets d’interaction des orientations morales et opportunistes de tiers non impliqués sur la relation entre la légitimé perçue ou les sanctions négatives attendues et leur intention de se ranger aux côtés d’un groupe légitime ou d’un groupe puissant. On a présentéà 79 salariés chinois et 77 salariés néerlandais un scénario décrivant un dilemme conflictuel entre un groupe qui disposait de plus de légitimité, mais de sanctions négatives moindres et un autre groupe qui disposait de moins de légitimité, mais de sanctions négatives plus fortes. Les résultats montrent que l’orientation morale exerce par elle‐même un renforcement sur la liaison positive entre la légitimité perçue et le fait de se ranger aux côtés d’un groupe bénéficiant de la légitimité. De plus, dans les deux pays, la relation entre les sanctions négatives attendues et le fait de choisir le groupe puissant était régulé par un effet conjugué des orientations morales et opportunistes. Ce qui signifie que pour des tiers pourvus d’une orientation morale déficiente et d’un grand opportunisme, une augmentation des sanctions négatives incite à prendre plutôt parti pour le groupe puissant. La relation ci‐dessus mentionnée n’est nullement positive pour les tiers à la morale et à l’opportunisme faibles, à la morale et à l’opportunisme forts, ou à la morale forte et à l’opportunisme faible.
The Moderating Effect of Trainee Implicit Beliefs on the Relationship between Cognitive Modeling Orientation and Training Outcomes
Authors: Sue‐Chan Christina , Wood Robert E. 
Published: June 2008

Two studies investigated the interactive effects of trainees’ dispositional implicit theory of ability (entity versus incremental) and the use of a promotion versus prevention orientation during the cognitive modeling component of training in the use of a problem‐solving technique. The dependent variables were trainees’ self‐reported behavioral intentions (Study 1) and performance (Study 2), which was assessed by two independent judges following the training program and in a 1‐month follow‐up in the use of the problem‐solving technique. As predicted, entity theorists were more responsive to the social cues contained in the promotion and prevention orientations during the cognitive modeling of the problem‐solving technique. As a result, a promotion orientation produced stronger behavioral intentions (Study 1) and performance (Study 2) than a prevention orientation for entity theorists but not for incremental theorists. The results point to the need to understand the implicit theories of trainees, particularly those who have an entity theory of ability, and for trainers to adopt a strong promotion orientation in their presentation of materials. Trainers who stress the avoidance of errors and overemphasise the importance of performance may unwittingly undermine the intentions and performance of those who have doubts about the efficacy of the training.Deux recherches ont porté sur l’interaction chez des sujets en formation des conséquences de la théorie implicite des capacités dont chacun dispose (stables ou amendables) et de l’orientation vers la prudence ou le progrès lors de la modélisation cognitive dans l’utilisation d’une technique de résolution de problèmes. Les variables dépendantes étaient les intentions comportementales rapportées par les stagiaires (Recherche n˚ 1) et la performance (Recherche n° 2) évaluée par deux juges indépendants à la fin du programme de formation et un mois plus tard. Comme prévu, les partisans des capacités stables étaient plus sensibles aux signes sociaux présents dans les orientations prudence ou progrès lors de l’élaboration cognitive de la technique de résolution de problèmes. Une orientation vers le progrès était à l’origine d’intentions comportementales plus affirmées (Recherche n˚ 1) et d’une meilleure performance (Recherche n˚ 2) pour les tenants de la stabilité des capacités, mais pas pour ceux qui pensaient que les capacités pouvaient être améliorées. Ces résultats montrent qu’il est indispensable de prendre en considération les théories implicites des stagiaires, et plus particulièrement de ceux qui pensent que les capacités sont figées. Quant aux formateurs, il leur faut adopter une orientation fortement axée sur le progrès dans leur présentation des contenus. Les formateurs qui insistent sur l’évitement des erreurs et exagèrent l’importance de la performance peuvent involontairement nuire aux intentions et aux résultats de ceux qui doutent de l’efficacité de la formation.
Measurement Equivalence of Paper‐and‐Pencil and Internet Organisational Surveys: A Large Scale Examination in 16 Countries
Authors: De Beuckelaer Alain , Lievens Filip 
Published: June 2008

In multinational surveys, mixed‐mode administration modes (e.g. combining Internet and paper‐and‐pencil administration) are increasingly used. To date, no studies have investigated whether measurement equivalence exists between Internet data collection and data collection using the conventional paper‐and‐pencil method in organisational surveys which include a large number of countries. This paper examined the measurement equivalence of a truly global organisational survey across Internet and paper‐and‐pencil survey administrations. Data from an organisational survey in 16 countries (N = 52,461) across the globe were used to assess the measurement equivalence of an organisational climate measure within each country in which the survey was administered. The empirical data provided strong indications which support the measurement equivalence of the multi‐item survey instrument across Internet and paper‐and‐pencil surveys in virtually all countries in which the survey was conducted. These findings suggest that merging data obtained through Internet and paper‐and‐pencil data administration in a particular country is legitimate as no evidence was found for differential effects across both modes of data collection.Dans les enquêtes internationales, les modalités d’administration mixtes, c’est‐à‐dire combinant les solution Internet et papier‐crayon, sont de plus en plus utilisées. Jusqu’à présent, on ignore si le recueil de données par Internet est méthodologiquement équivalent au recueil traditionnel sur papier dans les enquêtes organisationnelles qui couvrent un grand nombre de pays. Dans cet article, on analyse l’analogie des mesures d’une enquête organisationnelle véritablement universelle utilisant à la fois une administration Internet et papier‐crayon. Des données provenant de seize pays (N = 52,461) répartis sur l’ensemble de la planète ont été exploitées pour évaluer l’équivalence méthodologique d’une mesure du climat organisationnel dans chacun de ces pays. Les résultats empiriques sont en faveur de l’équivalence méthodologique de l’ensemble des items pour les recueils Internet et papier‐crayon dans pratiquement tous les pays retenus pour l’enquête. Ces résultats montrent qu’il est légitime de traiter ensemble les données obtenues par Internet et par papier‐crayon dans un même pays puisque rien ne nous permet d’affirmer l’existence d’un effet différentiel dû aux deux modes d’administration.
Benefits of Accounts of Well‐Being— For Societies and for Psychological Science
Authors: Diener Ed , Kesebir Pelin , Lucas Richard 
Published: June 2008

The decisions of business leaders and government officials are currently guided by economic and social indicators. It is proposed that accounts of well‐being be collected on an ongoing basis to complement the existing indicators. Accounts of subjective well‐being would track the societal groups where happiness, life satisfaction, engagement, and positive feelings are high versus low, would indicate the activities that people find enjoyable versus unpleasant, and would monitor changing levels of well‐being over time. The accounts would serve decision‐makers by making important information on well‐being and ill‐being available to them. They would also greatly help applied psychology by drawing more attention and interest to important outcomes that are likely to result from psychological interventions.Les décisions des chefs d’entreprise et des responsables gouvernementaux se fondent actuellement sur des indicateurs sociaux et économiques. On propose de recueillir des données relatives au bien‐être de façon continue en complément des indicateurs existants. Les mesures du bien‐être subjectif détecteraient les groupes sociaux où le bonheur, la satisfaction de vivre, le sens des responsabilités et les sentiments positifs sont élevés ou bas, indiqueraient les activités que les gens trouvent agréables ou non et suivraient avec le temps les changements dans le niveau du bien‐être. Ces mesures seraient utiles aux décisionnaires en mettant à leur disposition des informations importantes sur le bien‐être et son contraire. Elles seraient aussi d’un grand secours pour la psychologie appliquée en accordant davantage d’attention et d’intérêt aux conséquences importantes susceptibles de résulter des interventions psychologiques.
