Influence of Native Flowering Plant Strips on Natural Enemies and Herbivores in Adjacent Blueberry Fields

ABSTRACT Conservation plantings of native wildflowers were established adjacent to highbush blueberry (Vaccinium corymbosum L.) fields to test the hypothesis that provision of resources for natural enemies increases their abundance in adjacent crop fields without increasing the abundance of pest insects. For two growing seasons, natural enemies and herbivorous insects were sampled in fields with flowering borders and in control fields where growers maintained standard mown grass perimeters. Insects were categorized according to their trophic level and their potential pest status, and their abundance was compared between years and between treatments. Syrphid flies (Diptera: Syrphidae) were significantly more abundant in fields with conservation strips, as were plant bugs (Hemiptera: Miridae), thrips (Thysanoptera: Thripidae), and hoppers (Hemiptera: Auchenorrhyncha). Aphids (Hemiptera: Aphididae), thrips, fruit flies (Diptera: Tephritidae), and pirate bugs (Hemiptera: Anthocoridae) decreased significantly in abundance from 2007 to 2008. Beneficial insect abundance in crop fields increased in the latter half of the season in both years and this increase was more pronounced in fields adjacent to conservation plantings. We discuss the implications of these findings for pest management and conservation of biodiversity in farmland.
Metabolic Changes in the Spinal Cord After Brachial Plexus Root Re-implantation

Objective. To investigate metabolic changes within the spinal cord using proton magnetic resonance spectroscopy (1H-MRS) and determine their relationship with clinical function in patients with complete brachial plexus avulsion who underwent reimplantation of the ventral roots. Methods. Single-voxel 1H-MRS of the cord between C1 and C3 was performed in 10 patients with normal spinal cord on MRI, who underwent reimplantation of C5 to T1 ventral roots on average 5.5 years earlier, and 19 healthy controls. The ratios of the concentrations of the following main metabolites, with respect to total creatine levels, were obtained: total N-acetyl-aspartate, choline-containing compounds, creatine and phosphocreatine (Cr), and myo-inositol (m-Ins). Patient disability was assessed using upper limb scales. Differences in metabolite concentration ratios and their correlations with disability were investigated. Results. Patients showed increased m-Ins/Cr ratio compared with controls, which was associated with the level of function of the affected arm and time from injury. Conclusions. The finding of increased m-Ins/Cr in patients suggests that reactive gliosis, perhaps in response to the degeneration of avulsed fibers, may occur in the spinal cord above the site of injury and be relevant to motor dysfunction. However, this pathological process appears to diminish with time. These insights underline the need to integrate metabolic imaging with structural and functional magnetic resonance imaging to obtain a complete view of spinal cord plasticity. Last, this study provides the first steps toward identifying markers to serve as outcome measures for trials comparing strategies of plexus repair following avulsion injury.
Using Linked Data in a heterogeneous Sensor Web: challenges, experiments and lessons learned

Abundant sensor data are now available online from a wealth of sources, which greatly enhance research efforts on the Digital Earth. The combination of distributed sensor networks and expanding citizen-sensing capabilities provides a more synchronized image of earth's social and physical landscapes. However, it remains difficult for researchers to use such heterogeneous Sensor Webs for scientific applications since data are published by following different standards and protocols and are in arbitrary formats. In this paper, we investigate the core challenges faced when consuming multiple sources for environmental applications using the Linked Data approach. We design and implement a system to achieve better data interoperability and integration by republishing real-world data into linked geo-sensor data. Our contributions include presenting: (1) best practices of re-using and matching the W3C Semantic Sensor Network (SSN) ontology and other popular ontologies for heterogeneous data modeling in the water resources application domain, (2) a newly developed spatial analysis tool for creating links, and (3) a set of RESTful OGC Sensor Observation Service (SOS) like Linked Data APIs. Our results show how a Linked Sensor Web can be built and used within the integrated water resource decision support application domain.
The relation between multi-cultural group work and the integration of home and international students

Group working skills are essential attributes for graduates in higher education, and are highly valued by prospective employers of home and international students. With increasing numbers of international students, with different social, cultural, and academic backgrounds, there is an opportunity to evaluate the students’ perceptions of, and the potential benefits for, student integration in multi-cultural group work. The research measured students’ attitudes towards multi-cultural group activities compared with different aspects of group work in general. The opinions of students in two departments, Chemistry and Geography & Planning, towards multi-cultural group work were generally positive, although international students had a better perception of the benefits, and were more likely to self-assign themselves to mixed groups, than home students. International students found the cognitive benefits of culturally mixed groups, and their effect on enhancing integration, more favourable than home students. Conversely, home students have a better overall perception of the benefits of the emotional aspects of the group work, how they will manage the assignment, the development of interpersonal skills, and group assessment than international students. In general, the results imply that tutors should deliberately assign students to multi-culturally mixed groups to encourage integration, and that the academic tasks for the assignments should be developed sensitively to encourage engagement with both cohorts of students.

A lower bound for linear approximate compaction

The lambda -approximate compaction problem is: given an input array of n values, each either 0 or 1, place each value in the output array so that all the 1s are in the first (1+ lambda )k array locations, where k is the number of 1's in the input. lambda is an accuracy parameter. This problem is of fundamental importance in parallel computation because of its applications to processor allocation and approximate counting. When lambda is a constant, the problem is called linear approximate compaction (LAC). On the CRCW PRAM model, there is an algorithm that solves approximate compaction in O((log log n)/sup 3/) time for lambda =/sup 1///sub loglogn/, using /sup n///sub (loglogn)3/ processors. This is close to the best possible. Specifically, the authors, prove that LAC requires Omega (log log n) time using O(n) processors. They also give a tradeoff between lambda and the processing time. For in <1, and lambda =n/sup in /, the time required is Omega (log/sup 1///sub in /). <<ETX>>
“Can It Read My Mind?” – What Do the Public and Experts Think of the Current (Mis)Uses of Neuroimaging?

Emerging applications of neuroimaging outside medicine and science have received intense public exposure through the media. Media misrepresentations can create a gulf between public and scientific understanding of the capabilities of neuroimaging and raise false expectations. To determine the extent of this effect and determine public opinions on acceptable uses and the need for regulation, we designed an electronic survey to obtain anonymous opinions from as wide a range of members of the public and neuroimaging experts as possible. The surveys ran from 1st June to 30 September 2010, asked 10 and 21 questions, respectively, about uses of neuroimaging outside traditional medical diagnosis, data storage, science communication and potential methods of regulation. We analysed the responses using descriptive statistics; 660 individuals responded to the public and 303 individuals responded to the expert survey. We found evidence of public skepticism about the use of neuroimaging for applications such as lie detection or to determine consumer preferences and considerable disquiet about use by employers or government and about how their data would be stored and used. While also somewhat skeptical about new applications of neuroimaging, experts grossly underestimated how often neuroimaging had been used as evidence in court. Although both the public and the experts rated highly the importance of a better informed public in limiting the inappropriate uses to which neuroimaging might be put, opinions differed on the need for, and mechanism of, actual regulation. Neuroscientists recognized the risks of inaccurate reporting of neuroimaging capabilities in the media but showed little motivation to engage with the public. The present study also emphasizes the need for better frameworks for scientific engagement with media and public education.
Quantitative Assessment of the T2 Relaxation Time of the Gluteus Muscles in Children with Duchenne Muscular Dystrophy: a Comparative Study Before and After Steroid Treatment

Objective To determine the feasibility of using T2 mapping as a quantitative method to longitudinally follow the disease activity in children with Duchenne muscular dystrophy (DMD) who are treated with steroids. Materials and Methods Eleven boys with DMD (age range: 5-14 years) underwent evaluation with the clinical functional score (CFS), and conventional pelvic MRI and T2 mapping before and during steroid therapy. The gluteus muscle inflammation and fatty infiltration were evaluated on conventional MRI. The histograms and mean T2 relaxation times were obtained from the T2 maps. The CFS, the conventional MRI findings and the T2 values were compared before and during steroid therapy. Results None of the patients showed interval change of their CFSs. On conventional MRI, none of the images showed muscle inflammation. During steroid treatment, two boys showed increased fatty infiltration on conventional MRI, and both had an increase of the mean T2 relaxation time (p < 0.05). The remaining nine boys had no increase in fatty infiltration. Of these, three showed an increased mean T2 relaxation time (p < 0.05), two showed no change and four showed a decreased mean T2 relaxation time (p < 0.05). Conclusion T2 mapping is a feasible technique to evaluate the longitudinal muscle changes in those children who receive steroid therapy for DMD. The differences of the mean T2 relaxation time may reflect alterations in disease activity, and even when the conventional MRI and CFS remain stable.
Further Results on the Efficiency of Markets for Foreign Exchange

s from these conditions cannot be the basis of a test of market efficiency, although it may be helpful for descriptive or forecasting purposes. The second popular technique for testing spot market efficiency has relied on the profitability of simple filter rule trading strategies.7 Some results indicate that small filters would have been profitable for some currencies during the floating rate period. However, there are many factors which cast doubt on the interpretation of these results. First, it is not clear, ex ante, that the size of the filter can be determined which assures or optimizes profits. Second, even a filter rule which earns a profit over a sustained period is likely to report losses during some interim periods. Thus there is an element of riskiness in these trading strategies which is difficult to measure and difficult to compare to some standard model. Data considerations do not allow us to analyze another potential problem related to filter rule strategies. Market-maker quotations are typically valid only for a small and specified volume of contracts and for a limited time span. It is therefore possible that supply and demand elasticities are sufficiently large so that unusual profits would be eliminated quickly after a small volume of trading. This is important if we want to distinguish an inefficient market which permits $10 billion worth of profitable transactions in one hour, versus an inefficient market which eliminates a profit opportunity after $1 million of trade in one minute. Forward-Market Efficiency. Empirical tests of forward market efficiency surveyed in Levich (1979) can be conveniently divided into four groups. First, there are regression tests which estimate models of the form (1) St+n = a + bFt,n + ut
Web-based Cases in Teaching and Learning – the Quality of Discussions and a Stage of Perspective Taking in Asynchronous Communication

The aim of this study is to examine the quality of asynchronous interaction in web-based conferencing among pre-service teachers. Because all successful communication presumes perspective-taking skills and reciprocal understanding among the participants, we study whether the students are able to reach in reciprocal interaction and thus create educationally relevant high-level web-based discussion. The research project has its foundation in socio-constructivist learning theories, one of the most important principles of which is the idea of apprenticeship in thinking. To create a learning project in web-based conferencing we developed pedagogical practices, which enhance higher-level networked communication and make use of theoretical and expert knowledge. The study combines the power of asynchronous conferencing with peer and mentor collaboration to electronically apprentice student learning. The subjects of the study are pre-service teachers in the United States (N ? =? 40) and Finland (N ? =? 30) who use an asynchronous web-based tool called Conferencing on the Web (COW) to collaborate in creating joint case-based descriptions in different areas of teaching and learning. The results point out different levels of web-based discussion. Three kinds were found: higher-level discussion, progressive discussion and lower-level discussion. More specific analysis of the quality of each discussion level focused on perspective taking in communication. The results support our hypothesis that higher-level perspective taking was related to higher-level discussion.
What Drives National Differences in Intensive Grandparental Childcare in Europe?

Objectives. Grandparents play an important role in looking after grandchildren, although intensive grandparental childcare varies considerably across Europe. Few studies have explicitly investigated the extent to which such cross-national variations are associated with national level differences in individual demographic and socio-economic distributions along with contextual-structural and cultural factors (e.g., variations in female labor force participation, childcare provision, and cultural attitudes). Methods. We used multilevel models to examine associations between intensive grandparental childcare and contextual-structural and cultural factors, after controlling for grandparent, parent, and child characteristics using nationally representative data from the Survey of Health, Ageing and Retirement in Europe. Results. Even controlling for cross-national differences in demographic and socio-economic distributions, contextual-structural factors play an important role in explaining grandparental childcare variations in Europe. In particular, higher levels of intensive grandparental childcare are found in countries with low labor force participation among younger and older women, and low formal childcare provision, where mothers in paid work largely rely on grandparental support on an almost daily basis. Discussion. Encouraging older women to remain in paid work is likely to have an impact on grandchild care which in turn may affect mothers’ employment, particularly in Southern European countries where there is little formal childcare.
Budget Impact Analysis of Rapid Screening for Staphylococcus aureus Colonization Among Patients Undergoing Elective Surgery in US Hospitals

Objective. To evaluate the economic impact of performing rapid testing for Staphylococcus aureus colonization before admission for all inpatients who are scheduled to undergo elective surgery and providing subsequent decolonization therapy for those patients found to be colonized with S. aureus. Methods. A budget impact model that used probabilistic sensitivity analysis to account for the uncertainties in the input variables was developed. Primary input variables included the marginal effect of S. aureus infection on patient outcomes among patients who underwent elective surgery, patient demographic characteristics, the prevalence of nasal carriage of S. aureus, the sensitivity and specificity of the rapid diagnostic test for S. aureus colonization, the efficacy of decolonization therapy for nasal carriage of S. aureus, and cost data. Data sources for the input variables included the 2003 Nationwide Inpatient Sample data and the published literature. Results. In 2003, there were an estimated 7,181,484 patients admitted to US hospitals for elective surgery. Our analysis indicated preadmission testing and subsequent decolonization therapy for patients colonized with S. aureus would have produced a mean annual cost savings to US hospitals of $231,538,400 (95% confidence interval [CI], -$300 million to $1.3 billion). The mean annual number of hospital-days that could have been eliminated was estimated at 364,919 days (95% CI, 67,893-926,983 days), and a mean of 935 in-hospital deaths (95% CI, 88-3,691) could have been avoided per year. Sensitivity analysis indicated a 64.5% probability that there would be cost savings to US hospitals as a result of preadmission testing and subsequent decolonization therapy. Conclusion. The addition of preadmission testing and decolonization therapy to standard care would result in significant cost savings, even after accounting for variations in the model input values.
Probiotics Supplementation Therapy for Pathological Neonatal Jaundice: A Systematic Review and Meta-Analysis

Background: Neonatal jaundice is a relatively prevalent disease and affects approximately 2.4–15% newborns. Probiotics supplementation therapy could assist to improve the recovery of neonatal jaundice, through enhancing immunity mainly by regulating bacterial colonies. However, there is limited evidence regarding the effect of probiotics on bilirubin level in neonates. Therefore, this study aims at systematically evaluating the efficacy and safety of probiotics supplement therapy for pathological neonatal jaundice. Methods: Databases including PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wan Fang Database (Wan Fang), Chinese Biomedical Literature Database (CBM), VIP Database for Chinese Technical Periodicals (VIP) were searched and the deadline is December 2016. Randomized controlled trials (RCTs) of probiotics supplementation for pathological neonatal jaundice in publications were extracted by two reviewers. The cochrane tool was applied to assessing the risk of bias of the trials. The extracted information of RCTs should include efficacy rate, serum total bilirubin level, time of jaundice fading, duration of phototherapy, duration of hospitalization, adverse reactions. The main outcomes of the trials were analyzed by Review Manager 5.3 software. The relative risks (RR) or mean difference (MD) with a 95% confidence interval (CI) was used to measure the effect. Results: 13 RCTs involving 1067 neonatal with jaundice were included in the meta-analysis. Probiotics supplementation treatment showed efficacy [RR: 1.19, 95% CI (1.12, 1.26), P < 0.00001] in neonatal jaundice. It not only decreased the total serum bilirubin level after 3day [MD: −18.05, 95% CI (−25.51, −10.58), P < 0.00001], 5day [MD: -23.49, 95% CI (−32.80, −14.18), P < 0.00001], 7day [MD: −33.01, 95% CI (−37.31, −28.70), P < 0.00001] treatment, but also decreased time of jaundice fading [MD: −1.91, 95% CI (−2.06, −1.75), P < 0.00001], as well as the duration of phototherapy [MD: −0.64, 95% CI (−0.84, −0.44), P < 0.00001] and hospitalization [MD: −2.68, 95% CI (−3.18, −2.17), P < 0.00001], when compared with the control group. Additionally, no serious adverse reaction was reported. Conclusion: This meta-analysis shows that probiotics supplementation therapy is an effective and safe treatment for pathological neonatal jaundice.
Hyponatraemia associated with cardiac tamponade and chronic fluid excess

We describe a complex case of hyponatraemia with two aetiologies. A 49-year-old man who drank 6 litres of dilute alcohol per day presented confused and oedematous with a serum sodium of 95 mmol/litre. Urine sodium was <10 mmol/litre and urine osmolality 440 mOsmol/kg. Chest x-ray demonstrated a globular heart. ECG showed saddle-shaped ST elevation. ECHO demonstrated a large pericardial effusion causing marked tamponade. Following pericardiocentesis there was a marked diuresis; serum sodium returned to normal after 2 weeks. A full recovery ensued. Cardiac tamponade is associated with antidiuresis via release of antidiuretic hormone (ADH). Tamponade is also associated with antinatriuresis. Antidiuresis and antinatriuresis usually balance in cardiac tamponade; excessive fluid intake may have caused an imbalance in this case.
Deletions of the long arm of chromosome 7 in myeloid disorders: loss of band 7q32 implies worst prognosis

Clinical and cytogenetic data were analysed in 54 patients with acute non‐lymphocytic leukaemias (ANLL) or MDS (myelodysplastic syndromes) and deletion of the long arm of chromosome 7 (7q−), in order to determine if there is a commonly deleted region in 7q and to establish possible correlations between karyotypic features, such as karyotype pattern, karyotype complexity, associated anomalies, and/or the type of deleted segments, and outcome of patients with these disorders.
Prognostic Nutritional Index and the Risk of Mortality in Patients With Acute Heart Failure

Background Nutritional status has been related to clinical outcomes in patients with heart failure. We assessed the association between nutritional status, indexed by prognostic nutritional index (PNI), and survival in patients hospitalized for acute heart failure. Methods and Results A total of 1673 patients (age 76±13 years, 68% men) hospitalized for acute heart failure in a tertiary medical center were analyzed. PNI was calculated as 10×serum albumin (g/dL)+0.005×total lymphocyte count (per mm3). National Death Registry was linked to identify the clinical outcomes of all‐cause and cardiovascular death. With increasing tertiles of PNI, age and N‐terminal probrain natriuretic peptide decreased, and body mass index, estimated glomerular filtration rate, and hemoglobin increased. During a mean follow‐up duration of 31.5 months, a higher PNI tertile was related to better survival free from all‐cause and cardiovascular mortality in the total study population and in participants with either reduced or preserved left ventricular ejection fraction. After accounting for age, sex, estimated glomerular filtration rate, left ventricular ejection fraction, serum sodium level, and on‐admission systolic blood pressure, PNI was independently associated with cardiovascular death and total mortality (hazard ratio per 1 SD of the natural logarithm of the PNI: 0.76 [95% CI, 0.66–0.87] and 0.79 [95% CI, 0.73–0.87], respectively). In subgroup analyses stratified by age, sex, left ventricular ejection fraction, body mass index, or estimated glomerular filtration rate, PNI was consistently related to mortality. Conclusions PNI is independently associated with long‐term survival in patients hospitalized for acute heart failure with either reduced or preserved left ventricular ejection fraction.
