A GLIMPSE-based search for 6.7-GHz methanol masers and the lifetime of their spectral features

The University of Tasmania Mt Pleasant 26-m and Ceduna 30-m radio telescopes have been used to search for 6.7-GHz class II methanol masers towards two hundred GLIMPSE sources. The target regions were selected on the basis of their mid-infrared colours as being likely to be young high-mass star formation regions and are either bright at 8.0 μm, or have extreme [3.6]-[4.5] colour. Methanol masers were detected towards 38 sites, nine of these being new detections. The prediction was that approximately 20 new 6.7-GHz methanol masers would be detected within 3.5 arcmin of the target GLIMPSE sources, but this is the case for only six of the new detections. A number of possible reasons for the discrepancy between the predicted and actual number of new detections have been investigated. It was not possible to draw any firm conclusions as to the cause, but it may be because many of the target sources are at an evolutionary phase prior to that associated with 6.7-GHz methanol masers. Through comparison of the spectra collected as part of this search with those in the literature, the average lifetime of individual 6.7-GHz methanol maser spectral features is estimated to be around 150 years, much longer than is observed for 22-GHz water masers.
The Moral Stereotypes of Liberals and Conservatives-1 Running Head : THE MORAL STEREOTYPES OF LIBERALS AND CONSERVATIVES The Moral Stereotypes of Liberals and Conservatives

We investigated the moral stereotypes political liberals and conservatives have of themselves and each other. In reality, liberals endorse the individual-focused moral concerns of compassion and fairness more than conservatives do, and conservatives endorse the group-focused moral concerns of ingroup loyalty, respect for authorities and traditions, and physical/spiritual purity more than liberals do. 2,212 U.S. participants filled out the Moral Foundations Questionnaire with their own answers, or as a typical liberal or conservative would answer. Across the political spectrum, moral stereotypes about “typical” liberals and conservatives correctly reflected the direction of actual differences in foundation endorsement but exaggerated the magnitude of these differences. Contrary to common theories of stereotyping, the moral stereotypes were not simple underestimations of the political outgroup’s morality. Both liberals and conservatives exaggerated the ideological extremity of moral concerns for the ingroup as well as the outgroup. Liberals were least accurate about both groups.
Facial Feature Extraction from Range Images using a 3D Morphable Model

In this paper, a novel scheme is introduced for human facial feature extraction. Unlike previous methods that fit a 3D morphable model to 2D intensity images, our scheme utilizes 3D range images to extract features without requiring manually-defined initial landmark points. A linear transformation is used to achieve the mapping between the 3D model and a 3D range image, which makes the computation simple and fast. Moreover, our scheme is robust to the illumination and pose variations. In addition to features from range images, extra features can be obtained by examining optional 2D texture images. Using our scheme, we can also perform automatic eye/mouth corner localization. Experimental results show the high accuracy and robustness of our scheme.
Osteogenic Differentiation of Dental Follicle Stem Cells

Background: Stem cells are defined as clonogenic cells capable of self-renewal and multi-lineage differentiation. A population of these cells has been identified in human Dental Follicle (DF). Dental Follicle Stem Cells (DFSCs) were found in pediatric unerupted wisdom teeth and have been shown to differentiate, under particular conditions, into various cell types of the mesenchymal tissues. Aim: The aim of this study was to investigate if cells isolated from DF show stem features, differentiate toward osteoblastic phenotype and express osteoblastic markers. Methods: We studied the immunophenotype of DFSCs by flow cytometric analysis, the osteoblastic markers of differentiated DFSCs were assayed by histochemical methods and real-time PCR. Results: We demonstrated that DFSCs expressed a heterogeneous assortment of makers associated with stemness. Moreover DFSCs differentiated into osteoblast-like cells, producing mineralized matrix nodules and expressed the typical osteoblastic markers, Alkaline Phosphatase (ALP) and Collagen I (Coll I). Conclusion: This study suggests that DFSCs may provide a cell source for tissue engineering of bone.
Take‐Up of Social Assistance Benefits: The Case of the French Homeless

A considerable number of studies have been conducted to measure and analyze the phenomenon of the non‐take‐up of social assistance. However, the homeless portion of this population has long remained outside the scope of this research, so that little is known about their non‐take‐up behavior. In this paper, we focus on this population using a French national survey and we derive measures for the non‐take‐up of French basic income support. Our findings indicate that there is a substantial rate of non‐take‐up among the homeless, but that this rate is lower than that for the general population: approximately 18% of eligible homeless persons do not claim benefits compared to 35% of the general population. Using a large set of variables, we investigate the determinants of non‐take‐up. We show that although some of these determinants are shared with the general population, as identified in the literature, the homeless population exhibits some particularities. Furthermore, our results also suggest that the poorest of the homeless have a larger non‐take‐up rate than other homeless. (This abstract was borrowed from another version of this item.)
Management of stones in the biliary tree.

Stones in the biliary tree may coexist with gall-bladder stones, may be found only in the common duct (in the absence of gall-bladder stones) or, more rarely, may be present in the intrahepatic biliary tree-as in the Caroli syndrome.1 One of the most frequent causes of choledocholithiasis, however, is the retained common duct stone which has been left behind inadvertently after elective or emergency cholecystectomy. Despite the routine use of intraoperative cholangiography, exploration of the common duct (where indicated) at the time of cholecystectomy and even, on occasions, the use of fibre optic choledochoscopy, there is still a 1-4% incidence of retained common duct stones after cholecystectomy.2 When stones are discovered in the biliary tree, there are several therapeutic options-including, in selected patients, the use of oral chenodeoxycholic (CDCA) or ursodeoxycholic (UDCA) acid, the gallstone dissolving agents which are more commonly used in the treatment of cholesterol-rich stones in the gall bladder.3 Elsewhere in this issue Dr Gianfranco Salvioli and his colleagues from Modena in Italy describe the results of a random allocation, double masked trial in 28 patients with uncomplicated biliary stones, half of whom were treated with 12 mg UDCA/kg/day in three divided doses, while the other half received placebo. Seventeen of these patients had stones in the gall bladder while four had a radiologically normal gall bladder with stones only in the biliary tree. Although the end point of the study was intended to be 24 months, only four of the 28 patients actually completed the two year trial-either because the stones had disappeared completely before that time, or because the patients developed biliary colic, pain or cholangitis, underwent surgery or simply 'dropped out'. None of the 14 patients given placebo showed evidence of gallstone dissolution, but seven of the 14 UDCA-treated patients showed complete disappearance of the stones, as judged by normal intravenous cholangiograms, after six, 12, or 18 months' treatment-while one showed partial gall stone dissolution (defined as at least a 25% reduction in stone diameter or the disappearance of one or more stones). If one arbitrarily classifies 'drop-outs' as treatment failures, then the complication rate, whether because of the stones or of the treatment, was higher in the placebo treated patients (12 out of 14) than in the UDCA-treated group (six out of 14). The reason for the 'drop-outs' in three of the 14 patients given UDCA is not stated. These patients may simply …
Discrete Forms of Amylose Are Synthesized by Isoforms of GBSSI in Pea Online version contains Web-only data. Article, publication date, and citation information can be found at www.plantcell.org/cgi/doi/10.1105/tpc.002907.

Amyloses with distinct molecular masses are found in the starch of pea embryos compared with the starch of pea leaves. In pea embryos, a granule-bound starch synthase protein (GBSSIa) is required for the synthesis of a significant portion of the amylose. However, this protein seems to be insignificant in the synthesis of amylose in pea leaves. cDNA clones encoding a second isoform of GBSSI, GBSSIb, have been isolated from pea leaves. Comparison of GBSSIa and GBSSIb activities shows them to have distinct properties. These differences have been confirmed by the expression of GBSSIa and GBSSIb in the amylose-free mutant of potato. GBSSIa and GBSSIb make distinct forms of amylose that differ in their molecular mass. These differences in product specificity, coupled with differences in the tissues in which GBSSIa and GBSSIb are most active, explain the distinct forms of amylose found in different tissues of pea. The shorter form of amylose formed by GBSSIa confers less susceptibility to the retrogradation of starch pastes than the amylose formed by GBSSIb. The product specificity of GBSSIa could provide beneficial attributes to starches for food and nonfood uses.
What is the difference between the purpose of usability and user experience evaluation methods

There are different interpretations of user experience that lead to different scopes of measure. The ISO definition suggests measures of user experience are similar to measures of satisfaction in usability. A survey at Nokia showed that user experience was interpreted in a similar way to usability, but with the addition of anticipation and hedonic responses. CHI 2009 SIG participants identified not just measurement methods, but methods that help understanding of how and why people use products. A distinction can be made between usability methods that have the objective of improving human performance, and user experience methods that have the objective of improving user satisfaction with achieving both pragmatic and hedonic goals. Sometimes the term “user experience” is used to refer to both approaches. DEFINITIONS OF USABILITY AND USER EXPERIENCE There has been a lot of recent debate about the scope of user experience, and how it should be defined [5]. The definition of user experience in ISO FDIS 9241-210 is:
Experiences of adolescent mothers in Costa Rica and the role of parental support

ABSTRACT Adolescent pregnancy is often thought of as a social problem, one that can cause the adolescent mother hardship, including poverty, low-educational attainment, and housing instability. Although much research has been conducted about adolescent pregnancy in the developed world, less has considered adolescent pregnancy in the developing world. This qualitative study focuses on women who were impoverished in Costa Rica who had been pregnant in adolescence. The goal of the study was to gain a better understanding of the lived experiences of the mothers, as well as the kinds of support they received during and after the pregnancy. The research sample consisted of 22 female participants who were impoverished and had experienced an unintended pregnancy in adolescence. The key finding from this study was that parental support was the most important factor in mitigating adolescent experiences of stress and negative feelings about their choices related to the pregnancy. The study has implications for the understanding of the experiences of women who are vulnerable with respect to adolescent pregnancies in Latin America and for Latina migrants to the United States.

Investigating learner attitudes toward e-books as learning tools: based on the activity theory approach

This paper investigates the use of e-books as learning tools in terms of learner satisfaction, usefulness, behavioral intention, and learning effectiveness. Based on the activity theory approach, this research develops a research model to understand learner attitudes toward e-books in two physical sizes: 10″ and 7″. Results suggest that screen size could affect learners' perceived self-efficacy in using 10″ and 7″ e-books. Interactive learning environments, acceptable screen size, perceived self-regulation, and self-efficacy could positively influence perceived satisfaction with and usefulness of e-books as learning tools. Perceived satisfaction and usefulness are crucial factors in learner behavioral intention which, in turn, contributes to learning effectiveness. The paper also proposes a conceptual research model based on the activity theory approach.
Determining Subcanopy Psidium cattleianum Invasion in Hawaiian Forests Using Imaging Spectroscopy

High-resolution airborne imaging spectroscopy represents a promising avenue for mapping the spread of invasive tree species through native forests, but for this technology to be useful to forest managers there are two main technical challenges that must be addressed: (1) mapping a single focal species amongst a diverse array of other tree species; and (2) detecting early outbreaks of invasive plant species that are often hidden beneath the forest canopy. To address these challenges, we investigated the performance of two single-class classification frameworks—Biased Support Vector Machine (BSVM) and Mixture Tuned Matched Filtering (MTMF)—to estimate the degree of Psidium cattleianum incidence over a range of forest vertical strata (relative canopy density). We demonstrate that both BSVM and MTMF have the ability to detect relative canopy density of a single focal plant species in a vertically stratified forest, but they differ in the degree of user input required. Our results suggest BSVM as a promising method to disentangle spectrally-mixed classifications, as this approach generates decision values from a similarity function (kernel), which optimizes complex comparisons between classes using a dynamic machine learning process.
Atypical nuclear localization of CD133 plasma membrane glycoprotein in rhabdomyosarcoma cell lines

CD133 (also known as prominin-1) is a cell surface glycoprotein that is widely used for the identification of stem cells. Furthermore, its glycosylated epitope, AC133, has recently been discussed as a marker of cancer stem cells in various human malignancies. During our recent experiments on rhabdomyosarcomas (RMS), we unexpectedly identified an atypical nuclear localization of CD133 in a relatively stable subset of cells in five RMS cell lines established in our laboratory. To the best of our knowledge, this atypical localization of CD133 has not yet been proven or analyzed in detail in cancer cells. In the present study, we verified the nuclear localization of CD133 in RMS cells using three independent anti-CD133 antibodies, including both rabbit polyclonal and mouse monoclonal antibodies. Indirect immunofluorescence and confocal microscopy followed by software cross-section analysis, transmission electron microscopy and cell fractionation with immunoblotting were also employed, and all the results undeniably confirmed the presence of CD133 in the nuclei of stable minor subpopulations of all five RMS cell lines. The proportion of cells showing an exclusive nuclear localization of CD133 ranged from 3.4 to 7.5%, with only minor differences observed among the individual anti-CD133 antibodies. Although the role of CD133 in the cell nucleus remains unclear, these results clearly indicate that this atypical nuclear localization of CD133 in a minor subpopulation of cancer cells is a common phenomenon in RMS cell lines.
The Response of Tail Risk Perceptions to Unconventional Monetary Policy

We evaluate the response of perceived tail risks in financial markets to the implementation of unconventional monetary policy by the U.S. Federal Reserve. Using information from out-of-money equity index options, we find that perceived risks decline significantly in response to both policy announcements and actual asset purchases. The announcement effects are strongest specifically for downside risk measures rather than simple measures of volatility (e.g. the VIX). The impact of actual purchases is strongest when driven by simultaneous expansion and the duration extension of the Federal Reserve's balance sheet. These effects of both announcements and purchases have been variable over time and particularly pronounced during the latest policy phases implemented in 2012, a period also coinciding with the Federal Reserve's more extensive use of forward guidance about short-term rates.
Near-critical path analysis of program activity graphs

Program activity graphs can be constructed from time-stamped traces of appropriate execution events. Information about the activities on the k longest execution paths is useful in the analysis of parallel program performance. In this paper, four algorithms for finding the near-critical paths of program activity graphs are presented and compared, including an efficient new algorithm that utilizes slack values calculated by the critical path method to perform a best-first search in linear space. The worst-case time and memory requirements of the new algorithm are in O(ke) and O(k+e), where e is the number of edges in the graph. Results confirming the efficiency of the algorithm are presented for five application programs. A framework for utilizing the near-critical path information is also described. The framework includes both statistical summaries and visualization capabilities. <<ETX>>
Somatic gain-of-function mutations in PIK3CA in patients with macrodactyly

Macrodactyly is a discrete congenital anomaly consisting of enlargement of all tissues localized to the terminal portions of a limb, typically within a ‘nerve territory’. The classic terminology for this condition is ‘lipofibromatous hamartoma of nerve’ or Type I macrodactyly. The peripheral nerve, itself, is enlarged both in circumference and in length. It is not related to neurofibromatosis (NF1), nor is it associated with vascular malformations, such as in the recently reported CLOVES syndrome. The specific nerve pathophysiology in this form of macrodactyly has not been well described and a genetic etiology for this specific form of enlargement is unknown. To identify the genetic cause of macrodactyly, we used whole-exome sequencing to identify somatic mutations present in the affected nerve of a single patient. We confirmed a novel mutation in PIK3CA (R115P) present in the patient's affected nerve tissue but not in blood DNA. Sequencing PIK3CA exons identified gain-of-function mutations (E542K, H1047L or H1047R) in the affected tissue of five additional unrelated patients; mutations were absent in blood DNA available from three patients. Immunocytochemistry confirmed AKT activation in cultured cells from the nerve of a macrodactyly patient. Additionally, we found that the most abnormal structure within the involved nerve in a macrodactylous digit is the perineurium, with additional secondary effects on the axon number and size. Thus, isolated congenital macrodactyly is caused by somatic activation of the PI3K/AKT cell-signaling pathway and is genetically and biochemically related to other overgrowth syndromes.
Sex and gender identity differences in psychological job outcomes among salespeople

Purpose – The purpose of this study was to determine whether there was any difference among sex and gender identity groups for salespeople in terms of psychological job outcomes, namely job stress, organizational commitment, intention to leave, and job satisfaction. Design/methodology/approach – Data was collected from salespeople using a survey. The questionnaire used was administered to a convenience sample of pharmaceutical salespeople from south-central region of Turkey, through a self-administered questionnaire. Findings – The findings suggested that there were differences between sex groups in psychological job outcomes except job stress, while there were differences between gender identity groups in all of them. There already exist sex differences and also gender identity differences regarding the job outcomes in sales force. Androgynous individuals have the most appropriate gender identity for sales profession, considering that they had a high level of job satisfaction and organizational commitment and a low level of job stress and intention to leave. Originality/value – The major contribution of this study to the literature and administrative implications is the enrichment of information concerning gender-based similarities and/or differences among salespeople in terms of job outcomes with a new and different approach.
Calmly coping: A Motivational Interviewing Via CoActive Life Coaching (MI-VIA-CALC) pilot intervention for university students with perceived levels of high stress

Stress is a campus problem. This pre-post pilot study assessed the impact of Motivational Interviewing via Co-Active Life Coaching (MI-via-CALC) on the stress management of 30 full-time, English-speaking Canadian undergraduate students, aged 17-24 years. Participants were assessed using the Perceived Stress Scale and Hospital Anxiety and Depression Scale at pre-, mid-, and post-intervention. Three one-way, repeated-measures ANOVAs were completed. Statistically significant differences in stress reduction were found between pre-intervention to mid-intervention and between pre-intervention to postintervention. No statistically significant differences occurred between mid- to post-intervention. Inductive content analysis of qualitative interviews at pre-, mid-, and post-intervention revealed participants' positive experiences.
Mixture of Experts Classification Using a Hierarchical Mixture Model

A three-level hierarchical mixture model for classification is presented that models the following data generation process: (1) the data are generated by a finite number of sources (clusters), and (2) the generation mechanism of each source assumes the existence of individual internal class-labeled sources (subclusters of the external cluster). The model estimates the posterior probability of class membership similar to a mixture of experts classifier. In order to learn the parameters of the model, we have developed a general training approach based on maximum likelihood that results in two efficient training algorithms. Compared to other classification mixture models, the proposed hierarchical model exhibits several advantages and provides improved classification performance as indicated by the experimental results.
