stimating salinity stress in sugarcane fields with spaceborne hyperspectral egetation indices

The presence of salt in the soil profile negatively affects the growth and development of vegetation. As a result, the spectral reflectance of vegetation canopies varies for different salinity levels. This research was conducted to (1) investigate the capability of satellite-based hyperspectral vegetation indices (VIs) for estimating soil salinity in agricultural fields, (2) evaluate the performance of 21 existing VIs and (3) develop new VIs based on a combination of wavelengths sensitive for multiple stresses and find the best one for estimating soil salinity. For this purpose a Hyperion image of September 2, 2010, and data on soil salinity at 108 locations in sugarcane (Saccharum officina L.) fields were used. Results show that soil salinity could well be estimated by some of these VIs. Indices related to chlorophyll absorption bands or based on a combination of chlorophyll and water absorption bands had the highest correlation with soil salinity. In contrast, indices that are only based on water absorption bands had low to medium correlations, while indices that use only visible bands did not perform well. From the investigated indices the optimized soil-adjusted vegetation index (OSAVI) had the strongest relationship (R2 = 0.69) with soil salinity for the training data, but it did not perform well in the validation phase. The validation procedure showed that the new salinity and water stress indices (SWSI) implemented in this study (SWSI-1, SWSI-2, SWSI-3) and the Vogelmann red edge index yielded the best results for estimating soil salinity for independent fields with root mean square errors of 1.14, 1.15, 1.17 and 1.15 dS/m, respectively. Our results show that soil salinity could be estimated by satellite-based hyperspectral VIs, but validation of obtained models for independent data is essential for selecting the best model.
The (in)convenience of care in preschool education: examining staff views on educare

Abstract It is generally accepted that Early Childhood Education and Care should adopt a holistic view on education, in which education and care are inseparable concepts. Perspectives of staff members themselves are, however, often absent in these educare debates. We conducted six video-elicited focus groups with various preschool staff members (n = 69) in Flanders (Belgium), which is well known for its split system in which children between two and a half and four years old are confronted with the pivotal transition from an informal or formal caring environment (home or childcare service) to a formal learning environment (preschool). With Maurice Hamington’s theory of embodied and performative care as a theoretical lens for this empirical study, we propose a new direction for pre- and in-service training, in which the use of emotions, embodied exchange and social responsibility has a central place.
Immune Biomarker Differences and Changes Comparing HCV Mono-Infected, HIV/HCV Co-Infected, and HCV Spontaneously Cleared Patients

Background Immune biomarkers are implicated in HCV treatment response, fibrosis, and accelerated pathogenesis of comorbidities, though only D-dimer and C-reactive protein have been consistently studied. Few studies have evaluated HIV/HCV co-infection, and little longitudinal data exists describing a broader antiviral cytokine response Methods Fifty immune biomarkers were analyzed at baseline(BL) and HCV end of treatment follow-up(FU) time point using the Luminex 50-plex assay in plasma samples from 15 HCV-cleared, 24 HCV mono- and 49 HIV/HCV co-infected patients receiving antiretroviral treatment, who either did or did not receive pegylated-interferon/ribavirin HCV treatment. Biomarker levels were compared among spontaneous clearance patients, mono- and co-infected, untreated and HCV-treated, and sustained virologic responders (SVR) and non-responders (NR) at BL and FU using nonparametric analyses. A Bonferroni correction, adjusting for tests of 50 biomarkers, was used to reduce Type I error Results Compared to HCV patients at BL, HIV/HCV patients had 22 significantly higher and 4 significantly lower biomarker levels, following correction for multiple testing. There were no significantly different BL levels when comparing SVR and NR in mono- or co-infected patients; however, FU levels changed considerably in co-infected patients, with seven becoming significantly higher and eight becoming significantly lower in SVR patients. Longitudinally between BL and FU, 13 markers significantly changed in co-infected SVR patients, while none significantly changed in co-infected NR patients. There were also no significant changes in longitudinal analyses of mono-infected patients achieving SVR or mono-infected and co-infected groups deferring treatment Conclusions Clear differences exist in pattern and quantity of plasma immune biomarkers among HCV mono-infected, HIV/HCV co-infected, and HCV-cleared patients; and with SVR in co-infected patients treated for HCV. Though >90% of patients were male and co-infected had a larger percentage of African American patients, our findings may have implications for better understanding HCV pathogenesis, treatment outcomes, and future therapeutic targets
Ensemble LSDD-based change detection tests

The least squares density difference change detection test (LSDD-CDT) has proven to be an effective method in detecting concept drift by inspecting features derived from the discrepancy between two probability density functions (pdfs). The first pdf is associated with the concept drift free case, the second to the possible post change one. Interestingly, the method permits to control the ratio of false positives. This paper introduces and investigates the performance of a family of LSDD methods constructed by exploring different ensemble options applied to the basic CDT procedure. Experiments show that most of proposed methods are characterized by improved performance in change detection once compared with the direct ensemble-free counterpart.
On Witt vector cohomology for singular varieties

Over a perfect field $k$ of characteristic $p > 0$, we construct a ‘Witt vector cohomology with compact supports’ for separated $k$-schemes of finite type, extending (after tensorization with ${\mathbb Q}$) the classical theory for proper $k$-schemes. We define a canonical morphism from rigid cohomology with compact supports to Witt vector cohomology with compact supports, and we prove that it provides an identification between the latter and the slope ${<}1$ part of the former. Over a finite field, this allows one to compute congruences for the number of rational points in special examples. In particular, the congruence modulo the cardinality of the finite field of the number of rational points of a theta divisor on an abelian variety does not depend on the choice of the theta divisor. This answers positively a question by J.-P. Serre.
Parental indulgence, self-regulation, and young adults’ behavioral and emotional problems

ABSTRACT Because emotional and behavioral problems during young adulthood are an evolving public health concern, it is important to identify parenting behavior in the family of origin that prevents or exacerbates such problems. Therefore, we tested the impact of a unique parenting behavior – indulgent parenting – on emotional and behavioral problems through effects on self-regulation skills among college students, who face increasing developmental demands and challenges independent of parents. Using a sample of 459 college students, results from structural equation modeling suggested that (1) parental indulgence was positively associated with college students’ emotional and behavioral problems and (2) self-regulation mediated the association between parental indulgence and emotional and behavioral outcomes. Further, the findings revealed some perceived gender differences. Implications for parenting and young adult health interventions were discussed.
Periodic homogenization with an interface: The multi-dimensional case

We consider a diffusion process with coefficients that are periodic outside of an "interface region" of finite thickness. The question investigated in this article is the limiting long time/large scale behavior of such a process under diffusive rescaling. It is clear that outside of the interface, the limiting process must behave like Brownian motion, with diffusion matrices given by the standard theory of homogenization. The interesting behavior therefore occurs on the interface. Our main result is that the limiting process is a semimartingale whose bounded variation part is proportional to the local time spent on the interface. The proportionality vector can have nonzero components parallel to the interface, so that the limiting diffusion is not necessarily reversible. We also exhibit an explicit way of identifying its parameters in terms of the coefficients of the original diffusion. Similarly to the one-dimensional case, our method of proof relies on the framework provided by Freidlin and Wentzell [Ann. Probab. 21 (1993) 2215― 2245] for diffusion processes on a graph in order to identify the generator of the limiting process.
An analysis of a humidifier disinfectant case from a toxicological perspective

An analysis of patients and fatalities due to exposure to polyhexamethylene guanidine (PHMG) shows that PHMG causes mainly lung diseases such as pulmonary fibrosis. However, no research on the other organs has been conducted on this matter yet. So, an in-depth discussion on toxicological techniques is needed to determine whether or not PHMG is toxic to organs other than just the lungs. For the test of target organ toxicity by PHMG exposure, a toxicokinetic study must first be conducted. However, measurement method for PHMG injected into the body has not yet been established because it is not easy to analyze polymer PHMG, so related base studies on analytical technique for PHMG including radio-labeling chemistry must come first. Moreover, research on exposure-biomarker and effect-biomarker must also be conducted, primarily related to clinical application. Several limitations seem to be expected to apply the biomarker study to the patient because much time has passed after exposure to the humidifier disinfectant. It is why a more comprehensive toxicological researches must be introduced to the causality for the victims.
Fuzzy logic based collision avoidance for a mobile robot

Navigation and collision avoidance are major areas of research in mobile robotics that involve varying degrees of uncertainty. In general, the problem consists of achieving sensor based motion control of a mobile robot among obstacles in structured and/or unstructured environments with collision-free motion as the proirity. A fuzzy logic based intelligent control strategy has been developed here to computationally implement the approximate reasoning necessary for handling the uncertainty inherent in the collision avoidance problem. <<ETX>>
Epidemiology of Breast Cancer in Europe and Africa

Breast cancer continues to remain the most lethal malignancy in women across the world. This study reviews some of the epidemiological similarities and differences in breast cancer between white European women and black African women with the aim of optimising care for women with breast malignancy across the world. The incidence of breast cancer is lower among African women than their European counterparts. Majority of women in Europe are postmenopausal when they present with breast cancer; however, the peak incidence among African women is in the premenopausal period. Ductal carcinoma is the commonest type of breast cancer among women in Africa and Europe. However, medullary and mucinous carcinomas are more common in Africa than in Europe. While European women usually present at an early stage especially with the advent of screening, African women generally present late for treatment resulting in lower survival rates. There should be more research at the molecular level among African women to identify genetic factors that may contribute to the risk of developing breast cancer. There should also be improvement in the health care system in Africa in order to optimise care for women with breast cancer.
Crocin exerts anti-inflammatory and anti-catabolic effects on rat intervertebral discs by suppressing the activation of JNK

As intervertebral disc (IVD) degeneration has been proven to contribute to low back pain (LBP), drug treatment aiming at attenuating IVD degeneration may prove to be benefiical. Crocin, a bioactive component of saffron, has been found to exert anti-inflammatory effects on cartilage. In the present study, the anti-inflammatory and anti-catabolic effects of crocin on rat IVDs were analyzed in vitro and ex vivo. Nucleus pulposus (NP) cells were isolated from the lumbar IVDs of Sprague-Dawley rats. The NP cells were first treated with various concentrations of crocin, and then stimulated with lipopolysaccharide (LPS) to induce inflammation. Subsequently, RT-qPCR and enzyme-linked immunosorbent assay were carried out to measure the expression levels of catabolic enzymes, pro-inflammatory factors and the components of the extracellular matrix (ECM). In addition, western blot analysis was also used to investigate the related signaling pathways. The whole spinal motion segment (vertebra-IVD-vertebra section) of the rats was isolated and cultured in the presence or absence of LPS and crocin for 7 days. The ex vivo effects of crocin on the ECM of the IVD structures were determined by histological and biochemical analysis. In vitro, crocin significantly inhibited the LPS-induced overexpression of catabolic enzymes [matrix metalloproteinase (MMP)-1, MMP-3, MMP-13, a disintegrin-like and metalloprotease (reprolysin type) with thrombospondin type 1 motif (ADAMTS)-4 and ADAMTS-5], pro-inflammatory factors [interleukin (IL)-1β, tumor necrosis factor (TNF)-α, IL-6 and inducible nitric oxide synthase (iNOS)] and Toll-like receptor (TLR)-2 in a concentration-dependent manner. Notably, crocin partly prevented the downregulation of aggrecan and type II collagen (collagen-II). Moreover, crocin suppressed the LPS-induced activation of the mitogen-activated protein kinase (MAPK) pathway by inhibiting the phosphorylation of c-Jun N-terminal kinase (JNK). Ex vivo experiments demonstrated that crocin protected the rat IVDs from the LPS-induced depletion of the ECM components, including proteoglycan and collagen-II. In conclusion, crocin effectively suppressed the degeneration-related inflammation and catabolism in rat IVDs in vitro and ex vivo, suggesting that crocin has potential for use as a therapuetic strategy in the treatment of LBP.
Privacy in the new era of visible and sharable energy-use information

A new era of visible and sharable electricity information is emerging. Where eco-feedback is installed, households can now visualise many aspects of their energy consumption and share this information with others through Internet platforms such as social media. Despite providing users with many affordances, eco-feedback information can make public previously private actions from within the intimate setting of the family home. This paper represents a study focussing specifically on the privacy aspects of nascent ways for viewing and sharing this new stream of personal information. It explores the nuances of privacy related to eco-feedback both within and beyond the family home. While electricity consumption information may not be considered private itself, the household practices which eco-feedback systems makes visible may be private. We show that breaches of privacy can occur in unexpected ways and have the potential to cause distress. The paper concludes with some suggestions for how to realise the benefits of sharing energy consumption information whist effectively maintaining individuals' conceptions of adequate privacy.
Owner Occupation, Social Mix and Neighbourhood Impacts

There is interest within the social exclusion debate about the extent to which people in deprived social housing estates are socially isolated and their material disadvantages reinforced by exclusion from job opportunities and inward-looking and negative social norms. One approach to this problem has been the introduction of a social mix through the development of new housing for owneroccupation. Through interviews with and diaries kept by residents in three Scottish estates this article charts residents' networks and assesses the potential for owner-occupation to 'reconnect' existing residents with society beyond the local neighbourhood. The article concludes that owners and renters in regeneration areas largely inhabit different social worlds and that the introduction of owner-occupation makes little difference to renters' networks. Policy implications include the need to meet the housing aspirations of homeowners in these areas, and the effects of promoting largescale commercial developments based on heavy car use in towns and cities.
Stories from the field: mobile phone usage and its impact on people's lives in East Africa

In this paper we present results from contextual interviews and observations, which we conducted in Tanzania over a period of six weeks. In our interviews we focused on use cases and benefits that the mobile phone introduced in these areas. Specifically we were interested in the impact of mobile ICTs on social networks in general and communication with friends and family in particular. The goal of the study was to identify potential areas where ICTs could improve people's lives. Based on an analysis of the results from this study we created personas, which describe archetype mobile phone users and their respective needs and goals. The paper concludes with a number of directions for further research in this area.
Treatment goals and their attainment: a structured approach to assessment and evaluation

Abstract Treatment goals are considered a vital part of therapeutic work, and their role is often emphasized in cognitive behavioural therapy (CBT). However, the attainment of goals is rarely accounted for in terms of treatment outcome. In this study, we set out to investigate a structured format for goal assessment and goal attainment in CBT delivered as routine care. We were especially interested in the sensitivity to change in perceived goal attainment. Patients completed a self-administered version of the Bern Inventory of Treatment Goals (BIT-C) and rated their perceived attainment on a maximum of five prioritized goals before and after 12 weeks of treatment, along with measures on anxiety, depression and health-related quality of life. The results indicated that the prioritized goals only partially correspond to disorder-specific concerns, and that perceived proximity to treatment goals is clearly associated with improvements following treatment. The results are discussed in terms of the BIT-C being a promising tool for use in clinical settings in assessing treatment goals as well as in evaluating the attainment of these goals.
A Three-Way AutoCorrelation Based Approach to Human Identification by Gait

We propose a scheme for gait recognition using cubic higher-order local auto-correlation (CHLAC), discriminant analysis, and k-NN decision rules. CHLAC is based on three-way (x-, y-, and time-dimensional) auto-correlations of pixels in motion images, and it effectively extracts motion features. The method has several properties preferable for recognition: shift-invariance (rendering the method segmentation-free) and robustness to noise in data. Moreover, the method is so general as to use neither a priori knowledge nor heuristics about objects such as human shapes and is applicable to any three-way data. We made the scheme more effective for gait recognition by introducing some knowledge of gait to optimise parameters in CHLAC. Our scheme was applied to the NIST gait dataset for human identification, and the result was compared to those of other methods. Our scheme outperformed the others in spite of the simple feature extraction and the simple classification rule.
Circulating MicroRNAs and Aerobic Fitness – The HUNT-Study

Aerobic fitness, measured as maximal oxygen uptake (VO2max), is a good indicator of cardiovascular health, and a strong predictor of cardiovascular mortality. Biomarkers associated with low VO2max may therefore represent potential early markers of future cardiovascular disease (CVD). The aim of this study was to assess whether circulating microRNAs (miRs) are associated with VO2max-level in healthy individuals. In a screening study, 720 miRs were measured in serum samples from healthy individuals (40–45 yrs) with high (n = 12) or low (n = 12) VO2max matched for gender, age and physical activity. Candiate miRs were validated in a second cohort of subjects with high (n = 38) or low (n = 38) VO2max. miR-210 and miR-222 were found to be higher in the low VO2max-group (p<0.05). In addition, miR-21 was increased in male participants with low VO2max (p<0.05). There were no correlations between traditional risk factors for CVD (blood pressure, cholesterol, smoking habit, or obesity) and miR-21, miR-210 and miR-222. DIANA-mirPath identified 611 potential gene-targets of miR-21, miR-210 and miR-222, and pathway analysis indicated alterations in several important signaling systems in subjects with low VO2max. Potential bias involve that blood was collected from non-fasting individuals, and that 8 performed exercise within 24 h before sampling. In conclusion, we found that miR-210, miR-21, and miR-222 were increased in healthy subjects with low VO2max. The lack of association between these three miRs, and other fitness related variables as well as traditional CVD risk factors, suggests that these miRs may have a potential as new independent biomarkers of fitness level and future CVD.
Identification of high risk anaplastic gliomas by a diagnostic and prognostic signature derived from mRNA expression profiling

Anaplastic gliomas are characterized by variable clinical and genetic features, but there are few studies focusing on the substratification of anaplastic gliomas. To identify a more objective and applicable classification of anaplastic gliomas, we analyzed whole genome mRNA expression profiling of four independent datasets. Univariate Cox regression, linear risk score formula and receiver operating characteristic (ROC) curve were applied to derive a gene signature with best prognostic performance. The corresponding clinical and molecular information were further analyzed for interpretation of the different prognosis and the independence of the signature. Gene ontology (GO), Gene Set Variation Analysis (GSVA) and Gene Set Enrichment Analysis (GSEA) were performed for functional annotation of the differences. We found a three-gene signature, by applying which, the anaplastic gliomas could be divided into low risk and high risk groups. The two groups showed a high concordance with grade II and grade IV gliomas, respectively. The high risk group was more aggressive and complex. The three-gene signature showed diagnostic and prognostic value in anaplastic gliomas.
Humans Show Mate Copying After Observing Real Mate Choices: (597902013-004)

When searching for a mate, one must gather information to determine the mate value of potential partners. By focusing on individuals who have been previously chosen by others, one's selection of mates can be influenced by another's successful search—a phenomenon known as mate copying. We show mate copying in humans with a novel methodology that closely mimics behavioral studies with nonhuman animals. After observing instances of real mating interest in video recordings of speed-dates, both male and female participants show mate copying effects of heightened short-term and long-term relationship interest towards individuals in dates they perceived as successful. Furthermore, the relative attractiveness of observers and observed plays a mediating role in whom an individual will choose to copy. © 2010 Published by Elsevier Inc.
