Assurance of Sustainability Reports: Impact on Report Users' Confidence and Perceptions of Information Credibility

This study examines whether (1) assurance, (2) the level of assurance (reasonable vs limited) and (3) the type of assurance practitioner (accountant vs specialist consultant) affect users' perceptions of reliability of sustainability reports. Based on an experimental questionnaire, we find that the provision of assurance improves perceived reliability of the environmental and social information. There are no significant main effects for both the level of assurance and type of assurance practitioner. However, a significant interaction is found between these two experimental factors and report users' perceptions of reliability of such reports. More specifically, report users place more confidence in sustainability reports when the level of assurance provided is reasonable (that is, high but not absolute), and when such assurance is provided by a top tier accountancy firm, compared to when the assurance is provided by a specialist consultant. No such difference is found when the level of assurance provided is limited for either type of assurance practitioner group. The results of this study thus highlight the relevance of assurance for sustainability reporting.
Innovation in Local Economies: Germany in Comparative Context

The study of varieties of capitalism is moving on from the analysis of static national types to embrace local and sectoral diversity and the study of systems in the process of major change. This volume addresses the issue by examining four localised sectors, comparing a German case with one in another European country. The general changes taking place in Germany itself and the other countries (Hungary, Sweden, and the UK) form the context of the studies. The case studies concern: * Furniture making in North-Rhine Westphalia and southern Sweden, * Automotive manufacture in east Germany and northern Hungary, * Biotechnology around Munich and Cambridge, * TV programme and film-making in Cologne and central London. The studies find a complex pattern of conformity with, and deviation from, national types, but only occasional examples of where divergence takes the form of a direct confrontation with a national model. This is partly because national models are themselves changing; partly because they are often capable of accommodating more diversity than is often assumed by national studies; and partly because firms are increasingly able to reach outside their national boundaries for institutional resources.

Genome Sequence of the Polysaccharide-Degrading, Thermophilic Anaerobe Spirochaeta thermophila DSM 6192

ABSTRACT Spirochaeta thermophila is a thermophilic, free-living anaerobe that is able to degrade various α- and β-linked sugar polymers, including cellulose. We report here the complete genome sequence of S. thermophila DSM 6192, which is the first genome sequence of a thermophilic, free-living member of the Spirochaetes phylum. The genome data reveal a high density of genes encoding enzymes from more than 30 glycoside hydrolase families, a noncellulosomal enzyme system for (hemi)cellulose degradation, and indicate the presence of a novel carbohydrate-binding module.
Leaving China's Farms: Survey Results of New Paths and Remaining Hurdles to Rural Migration

One of the striking outcomes of China's economic reforms is the emergence of inter-regional labour markets as rural workers have poured into the nation's urban and rural economies. Policy makers in China, as elsewhere in the world, have treated the inter-regional migrant labour force with ambiguity. Migration may increase efficiency, contribute to poverty reduction and make China's economy more competitive, but leaders fear the congestion, social unrest and loss of political control which might accompany an increasingly mobile labour force.
Community Families: Bridging the gap between mental health services and civil society – A qualitative study from users’ perspective

Background: Social interventions to support people with severe mental illness are important to improving the quality of life. The perspectives of users are essential in this process. This article explores users’ experiences, investments and concerns of a befriending programme. Material: Focus group and individual qualitative interviews with service users. Discussion: Overall, the experiences with the programme were positive, and the social interaction was highly valued. However, that the relationships were arranged and facilitated by mental health workers remained an unresolved concern even after several years. Conclusion: People with severe mental illness benefit from relationships despite the need of professional assistant.
Role of Adaptor TRIF in the MyD88-Independent Toll-Like Receptor Signaling Pathway

Stimulation of Toll-like receptors (TLRs) triggers activation of a common MyD88-dependent signaling pathway as well as a MyD88-independent pathway that is unique to TLR3 and TLR4 signaling pathways leading to interferon (IFN)-β production. Here we disrupted the gene encoding a Toll/IL-1 receptor (TIR) domain-containing adaptor, TRIF. TRIF-deficient mice were defective in both TLR3- and TLR4-mediated expression of IFN-β and activation of IRF-3. Furthermore, inflammatory cytokine production in response to the TLR4 ligand, but not to other TLR ligands, was severely impaired in TRIF-deficient macrophages. Mice deficient in both MyD88 and TRIF showed complete loss of nuclear factor kappa B activation in response to TLR4 stimulation. These findings demonstrate that TRIF is essential for TLR3- and TLR4-mediated signaling pathways facilitating mammalian antiviral host defense.
Pseudocontinuous arterial spin labeling with optimized tagging efficiency

The adiabatic inversion of blood in pseudocontinuous arterial spin labeling (PCASL) is highly sensitive to off‐resonance effects and gradient imperfections and this sensitivity can lead to tagging efficiency loss and unpredictable variations in cerebral blood flow estimates. This efficiency loss is caused by a phase tracking error between the RF pulses and the flowing spins. This article introduces a new method, referred to as Optimized PCASL (OptPCASL), that minimizes the phase tracking error by applying an additional compensation RF phase term and in‐plane gradients to the PCASL pulse train. The optimal RF phase and gradient amplitudes are determined using a prescan procedure, which consists of a series of short scans interleaved with automated postprocessing routines integrated to the scanner console. The prescan procedure is shown to minimize the phase tracking error in a robust and time efficient manner. As an example of its application, the use of OptPCASL for the improved detection of functional activation in the visual cortex is demonstrated and temporal signal‐to‐noise ratio (SNR), image SNR, and baseline cerebral blood flow measures are compared to those acquired from conventional PCASL.

An empirical study of harvesting-aware duty cycling in environmentally-powered wireless sensor networks

In an environmentally-powered wireless sensor network, where nodes are powered solely by harvesting energy from ambient sources, node operation highly depends on the energy availability and harvesting rate. For duty-cycling schemes to support existing wireless sensor network applications, they need to adapt the nodes' sleep-wake schedules according to energy harvesting and consumption rates. In this paper, we propose a harvesting-aware duty-cycling scheme, perform an empirical study of this scheme over a solar harvesting powered wireless sensor network in a source-relay-sink configuration, and provide some experimental results to illustrate its throughput performance under various light conditions.
Simulations based on representative 24-h recall data predict region-specific differences in adequacy of vitamin A intake among Cameroonian women and young children following large-scale fortification of vegetable oil and other potential food vehicles.

BACKGROUND The WHO recommends assessing food and nutrient intakes to design food-fortification programs, but nationally representative dietary data are seldom available in low-income countries. OBJECTIVE Prior to initiation of food fortification in Cameroon, we measured intake of vitamin A (VA) and fortifiable foods (vegetable oil, sugar, wheat flour, and bouillon cube) to simulate the effects of fortification with different foods and VA amounts on prevalence of inadequate and excessive VA intake. METHODS Twenty-four-hour recalls were conducted among 912 women and 883 children (with duplicates in a subset) in a nationally representative cluster survey stratified by region (North, South, Yaoundé/Douala). Usual intake distributions were estimated by the National Cancer Institute method. RESULTS Nationally, 53% of women had a usual intake of <500 μg retinol activity equivalents/d, and 59% of nonbreastfeeding children had an intake of <210 μg retinol activity equivalents/d, although VA intake varied by region. The current fortification program (12 mg/kg VA in oil) would decrease the prevalence of inadequate intakes to 35% among both women and children, without increasing the proportion with retinol intakes >3000 μg/d among women or >600 μg/d among children. However, inadequate VA intake would remain >50% in the North, where VA deficiency was most common. Increasing VA in oil or fortifying a second food (sugar, wheat flour, or bouillon cube) would further decrease the prevalence of inadequate intakes, but, depending on the food vehicle and region, would also increase the prevalence of retinol intakes above the tolerable upper intake level, mainly among children. CONCLUSIONS The current food-fortification program can be expected to improve dietary VA adequacy without increasing the risk of excessive intake among women and children in Cameroon. Modifications to the program must balance the potential to further increase VA intake with the risk of excessive intake among children.
Developing knowledge management metrics for measuring intellectual capital

Measuring intellectual capital is a growing area of interest in the knowledge management field. Metrics are being developed and applied by some organizations, but there needs to be more research throughout the international community to better define these measures. One limitation of the current measures is that they do not necessarily address the “knowledge level” and the types of value‐added knowledge that individuals obtain. This paper takes a look at the current measures, discusses some possible limitations, and suggests some additional measures that could be used in the intellectual capital area to complement existing measures.
Organization and transfer of heterologous chloramphenicol and tetracycline resistance genes in pneumococcus

The cat and tet genes of chloramphenicol- and tetracycline-resistant clinical isolates of Streptococcus pneumoniae from Paris and Japan were shown to be contained in adjacent heterologous insertions into the chromosome. The two insertions transformed laboratory strains at frequencies that were low, unequal, and, for tet, very sensitive to the length of the donor deoxyribonucleic acid strand. In contrast, the transforming activity of cat was relatively stable. There was an unusual asymmetric cotransfer, in that a majority of the tet transformants also acquired cat, whereas only a few of the cat transformants also acquired tet. The evidence for chromosomal insertion came from genetic data showing linkage of cat to a chromosomal gene and from cosedimentation of cat with chromosomal markers in both velocity and dye-buoyancy experiments. Genes on a known plasmid introduced into pneumococcus from Streptococcus faecalis showed very different physical behavior. Most of the transformation properties of these genes can be readily accounted for by analogy to transformation of deletions of normal genes. Whether transposition contributes any of the transfers remains to be determined. The presence of one of the genes in the recipient promoted the integration of the other, demonstrating enhanced accumulation of heterologous genes by a process that did not involve plasmids in the species of concern.
Effects of guaifenesin on nasal mucociliary clearance and ciliary beat frequency in healthy volunteers.

STUDY OBJECTIVE Mucociliary clearance is an important host defense function of the upper respiratory tract that requires the coordinated beating of cilia and results in the transport of mucus to the oropharynx. Guaifenesin is a commonly prescribed drug that is reported to improve the clearance of respiratory secretions. We hypothesized that guaifenesin increases nasal mucociliary clearance related to increases in ciliary beat frequency (CBF) and that a direct relationship exists between nasal CBF and nasal mucociliary clearance. DESIGN Double-blind placebo-controlled crossover study. PARTICIPANTS Ten healthy volunteers with a previous history of sinus disease. INTERVENTIONS Subjects received guaifenesin or placebo on days 1 to 7 or days 14 to 21. MEASUREMENTS AND RESULTS In vivo saccharine transit time (STT) was measured by noting the time in minutes required for the subject to taste a saccharin particle placed on the inferior turbinate of the naris. The CBF was determined by video microscopy on ten separate groups of beating ciliated nasal mucosal cells obtained by brushing immediately after each STT determination. We found that there was no significant change between the guaifenesin-or placebo-treated groups from baseline values of STT (p = 0.94) or CBF (p = 0.46). Regression analysis demonstrated no relationship between STT and CBF for repeated measures within subjects (mean r2 = 0.18; mean p = 0.66) and between STT and CBF when all paired measurements were combined across subjects (r2 = 0.47; p = 0.46). CONCLUSION We conclude that guaifenesin exerts no measurable effect on in vivo nasal mucociliary clearance or ex vivo nasal ciliary motility in healthy volunteers with previous sinus disease. In addition, there appears to be no relationship between nasal STT measured in vivo and CBF measured ex vivo. The lack of correlation is most likely due to variations in CBF related to sampling artifacts introduced by the nasal brushing process.
Enterprise ownership, enterprise organisation, and worker attitudes in Chinese rural industry: some new evidence

China's Township and Village Enterprises (TVEs) have performed remarkably well during the post-1979 period. However, agreement on their organizational and behavioral characteristics and the reasons for their success remains elusive. For some, TVEs are simply private enterprises in disguise and behaviorally equivalent; for others, TVEs represent a unique form of enterprise organization based on collective ownership; the success of which poses a serious challenge to the conventional prescriptions favoring privatization. This paper reports findings from a small survey of private and collective rural enterprises in Heilongjiang, north-east China. The authors find strong evidence that differences in ownership are reflected in different forms of organizational behavior, residual payment structures, and in different worker attitudes and degrees of commitment to the enterprise.

Spontaneous and imitated productions in Spanish-speaking children with phonological disorders.

PURPOSE Research examining the relationship between spontaneous and imitated productions for phonological analysis has indicated that the inclusion of imitated productions may overestimate children's phonological abilities. Previous research in this area has included only English-speaking children. The purpose of this study was to determine what, if any, differences there were in the spontaneous and imitated productions of Spanish-speaking children with phonological disorders. METHOD Twelve Spanish-speaking children with phonological disorders (5 boys and 7 girls), ranging in age from 3;1 (years;months) to 4;9 (M = 3;11), participated in the study. Their spontaneous and imitated productions, based on a sample of single words, were analyzed to determine which elicitation task yielded the more adult-like production. Differences in consonant accuracy between the two tasks were analyzed, as was the shift in error type from spontaneous to imitated productions. RESULTS The results indicated that spontaneous and imitated productions were identical in 62% of the cases, an imitated production was more adult-like than a spontaneous one in 25% of the cases, and a spontaneous form was more adult-like than an imitated one in approximately 13% of the cases. Consonant accuracy for some children also varied as a function of elicitation task. CLINICAL IMPLICATIONS For additional diagnostic and prognostic value, speech-language pathologists can incorporate imitated responses in their analyses.
Effects of Music Tempo on Performance, Psychological, and Physiological Variables during 20 Km Cycling in Well-Trained Cyclists

Few studies have investigated the effects of music on trained athletes during high intensity endurance tasks. Therefore, this study investigated the effects of different music tempi on performance, psychological, and physiological responses of well-trained cyclists to time trial cycling. 10 male road cyclists (M age = 35 yr., SD = 7), with a minimum of three years racing experience, performed four 20-km time trials on a Computrainer™ Pro 3D indoor cycle trainer over a period of four weeks. The time-trials were spaced one week apart. The music conditions for each trial were randomised between fast-tempo (140 bpm), medium-tempo (120 bpm), slow-tempo (100 bpm), and no music. Performance (completion time, power output, average speed and cadence), physiological (heart rate, oxygen consumption, breathing frequency and respiratory exchange ratio), psychophysical (RPE), and psychological (mood states) data were collected for each trial. Results indicated no significant changes in performance, physiological, or psychophysical variables. Total mood disturbance and tension increased significantly in the fast-tempo trial when compared with medium and no-music conditions.
Prey consumption during development as well as longevity and reproduction of Typhlodromus pyri Scheuten (Acari, Phytoseiidae) at higher temperatures in the laboratory

The predatory mite Typhlodromus pyri Scheuten (Acari, Phytoseiidae) has been reported as an important predator of the European red mite, Panonychus ulmi (Koch) (Acari, Tetranychidae) in apple culture and vineyards at below 25 °C. However, sufficient biological data was lacking on its efficiency at temperatures above 25 °C. Therefore, the purpose of the present laboratory work was to obtain experimental data on prey consumption during development as well as longevity and reproduction of T. pyri on apple leaf discs and in Plexiglas cells at constant temperatures of 25 ± 2 °C and 30 ± 2 °C with P. ulmi as prey.The results showed that mean daily and total prey consumption by both the nymphs and adults of T. pyri decreased significantly on both the arenas as the temperature was increased from 25 °C to 30 °C, whereby adult prey consumption, both mean daily and total, was higher than that of nymphs. Prey consumption by both the nymphs and adults was significantly higher in the Plexiglas cells than on the leaf discs at both temperatures. Mean total prey consumption during nymphal development was 16.1 (♀♀) and 12.8 (♂♂) at 25 °C compared to 7.0 (♀♀) and 5.8 (♂♂) preys at 30 °C on the apple leaf discs and 46.0 (♀♀) and 38.5 (♂♂) at 25 °C compared to 25.2 (♀♀) and 20.3 (♂♂) preys at 30 °C in the Plexiglas cells. Mean duration of nymphal development was similar for the two sexes at the same temperature, but it was longer at 25 °C than at 30 °C. It was 6.0 and 4.0 days on the apple leaf discs while 7.0 and 6.0 days in the Plexiglas cells at 25 °C and 30 °C, respectively. Mean daily and total prey consumption by both male and female adults also decreased with the increasing temperature, whereby the females consumed more than double the mean total number of prey than the males on both the arenas of observation and at both temperatures: 355.4 versus 149.7 preys at 25 °C and 192.2 versus 85.6 preys at 30 °C on the leaf discs and 826.8 versus 374.5 preys at 25 °C and 488.9 versus 187.9 preys at 30 °C in the Plexiglas cells. Longevity of the females was longer than males on both arenas and at both temperatures and it was longer at 25 °C than at 30 °C. Mean total longevity on the apple leaf discs was 68.3 (♀♀) and 50.8 (♂♂) days at 25 °C compared to 52.5 (♀♀) and 36.8 (♂♂) days at 30 °C, while in the Plexiglas cells it was 91.0 (♀♀) and 65.8 (♂♂) days at 25 °C compared to 75.3 (♀♀) and 48.5 (♂♂) days at 30 °C. Reproduction in females also decreased significantly with increasing temperature. It decreased from 62.0 to 39.0 eggs/female on the leaf discs and 75.0 to 47.1 eggs/female in the Plexiglas cells. The females laid significantly higher numbers of eggs at both temperatures in the Plexiglas cells than on the leaf discs. Oviposition period in females was 30 days at 25 °C on both the arenas, while at 30 °C it was 26 days on the apple leaf discs and 27 days in the Plexiglas cells.
