Data coordination

In many scenarios, a contingent data source may benefit by coordinating with external heterogeneous sources upon which it depends. The administrator of this contingent source needs to update it when changes are made to the external base sources. For example, when a building design is updated, the contractor's cost estimate must be updated, too. The goal of data coordination is to update a contingent source, C, based on changes to an independently maintained base source, B. This paper introduces a data coordination system which allows C to coordinate its data without imposing significant requirements on B. Our system uses declarative mappings between B and C and performs coordination in two stages View Differencing --- finding changes to an intermediate view of B based on its mapping to C, and Update Translation --- translating the view differencing result into updates on C. We present and evaluate novel solutions to both stages and demonstrate their feasibility on real world problems.
NGC 4314. III. Inflowing Molecular Gas Feeding a Nuclear Ring of Star Formation

NGC 4314 is an early-type barred galaxy containing a nuclear ring of recent star formation. We present CO(1-0) interferometer data of the bar and circumnuclear region with 2.3 x 2.2 arcsec spatial resolution and 13 km/s velocity resolution acquired at the Owens Valley Radio Observatory . These data reveal a clumpy circumnuclear ring of molecular gas. We also find a peak of CO inside the ring within 2 arcsec of the optical center that is not associated with massive star formation. We construct a rotation curve from these CO kinematic data and the mass model of Combes et al. (1992). Using this rotation curve, we have identified the location of orbital resonances in the galaxy. Assuming that the bar ends at corotation, the circumnuclear ring of star formation lies between two Inner Lindblad Resonances, while the nuclear stellar bar ends near the IILR. Deviations from circular motion are detected just beyond the CO and H-alpha ring, where the dust lanes along the leading edge of the bar intersect the nuclear ring. These non-circular motions along the minor axis correspond to radially inward streaming motions at speeds of 20 - 90 km/s and clearly show inflowing gas feeding an ILR ring. There are bright HII regions near the ends of this inflow region, perhaps indicating triggering of star formation by the inflow.
Parental reflective functioning in fathers who use intimate partner violence: Findings from a Norwegian clinical sample

Abstract Few studies have examined fathering in an intimate partner violence (IPV) context outside the US. The present study included 36 Norwegian men who were voluntarily participating in therapy after perpetrating acts of IPV. They were interviewed with the revised Parent Development Interview, which is designed to assess parental reflective functioning (parental RF), and screened for alcohol- and substance-use habits and trauma history. At the group level, participants exhibited poor parental RF, high relational trauma scores, and elevated alcohol intake. Parental RF did not correlate with education level, alcohol or substance use, or compound measures of trauma history. There was a moderate negative relationship between having experienced physical abuse in childhood and parental RF.
Special Issue on Design and Development: Performance Measurement and Design in Supply Chains

This paper examines the relationship between product architecture, supply-chain performance metrics, and supply-chain efficiency. We model the contracting relationship between a supplier and a buyer. The supplier is privately informed about the outcome of his design/production investment. The buyer both appraises the supplier's component and does further processing/component production of his own. If the final product produced by the buyer exhibits decoupling and no function sharing with respect to the components termed separable architecture, the first-best outcome is attained if both internal and external failures are contractible. When only one type of failure can be contracted on, we derive conditions under which contracting on internal failure is superior to contracting on external failure, and vice versa. If the buyer's final product has a nonseparable architecture with respect to the components, first-best cannot be achieved even if both internal and external failures are contractible. The value of contracting on internal failure alone is unaffected by the architecture design, while that of external failure declines relative to the separable setting; the net result is often to make the former the uniformly dominant performance metric. Our results highlight the interaction between the performance metrics used for contracting within the supply chain, the architecture of the product produced by the supply chain, and the incentive efficiency of the chain.
Transcatheter aortic valve replacement: The year in review 2016

Transcatheter aortic valve replacement (TAVR) continued to make major strides in 2016, simultaneously expanding its application to lower risk patients as well as more technically challenging subsets of patients with aortic stenosis (AS). The two major accomplishments this year were the establishment of TAVR as the preferred treatment strategy over surgical aortic valve replacement (SAVR) in intermediate risk patients, and initial signals that TAVR and SAVR may be clinically equivalent in low-risk populations. Meanwhile, there is continued expansion of TAVR to challenging clinical subsets (bicuspid aortic valve [BAV], patients with concomitant advanced coronary artery disease [CAD], and failed surgical bioprostheses), and encouraging initial experiences with newer transcatheter heart valve systems. This paper summarizes the major research studies published on TAVR in 2016.
Improved Body Flexibility Following Removal of a Miniscrew Implant

A 65-year-old woman, who had been suffering from inflexibility, neck and eye pain as well as general discomfort and stiffness, experienced an improvement in her symptoms upon the removal of a dental miniscrew implant. However, her symptoms returned when the implant was placed near her foot. Her symptoms continued to improve for 6 months. We hypothesize that the cause of her symptoms is linked to electromagnetic waves attracted by the implant. However, the exact underlying mechanism remains unclear, and further research is required in cooperation with the dental, medical, and related fields.
Efficacy of antidepressive medication for depression in Parkinson disease: a network meta-analysis

Background: Parkinson disease (PD) was considered as the 2nd most prevalent neurodegenerative disorder after Alzheimer disease, while depression is a prevailing nonmotor symptom of PD. Typically used antidepression medication includes tricyclic antidepressants (TCA), selective serotonin reuptake inhibitors (SSRI), serotonin and norepinephrine reuptake inhibitors (SNRI), monoamine-oxidase inhibitors (MAOI), and dopamine agonists (DA). Our study aimed at evaluating the efficacy of antidepressive medications for depression of PD. Methods: Web of Science, PubMed, Embase, and the Cochrane library were searched for related articles. Traditional meta-analysis and network meta-analysis (NMA) were performed with outcomes including depression score, UPDRS-II, UPDRS-III, and adverse effects. Surface under the cumulative ranking curve (SUCRA) was also performed to illustrate the rank probabilities of different medications on various outcomes. The consistency of direct and indirect evidence was also assessed by node-splitting method. Results: Results of traditional pairwise meta-analysis were performed. Concerning depression score, significant improvement was observed in AD, MAOI, SSRI, and SNRI compared with placebo. NMA was performed and more information could be obtained. DA was illustrated to be effective over placebo concerning UPDRS-III, MAOI, and SNRI. DA demonstrated a better prognosis in UPDRS-II scores compared with placebo and MAOI. However, DA and SSRI demonstrated a significant increase in adverse effects compared with placebo. The SUCRA value was calculated to evaluate the ranking probabilities of all medications on investigated outcomes, and the consistency between direct and indirect evidences was assessed by node-splitting method. Conclusion: SSRI had a satisfying efficacy for the depression of PD patients and could improve activities of daily living and motor function of patient but the adverse effects are unneglectable. SNRI are the safest medication with high efficacy for depression as well while other outcomes are relatively poor.
Vocal fatigue and its relation to vocal hyperfunction

This article reviews current literature on vocal fatigue and considers its potential relationship to vocal hyperfunction. Vocal fatigue is defined by its symptoms. Specifically, the voice user perceives an increase in phonatory effort over time that may be accompanied by decreased phonatory function. Vocal fatigue can present as a pure condition, such that no specific aetiology is apparent, or as a component of other voice disorders. The underlying bases of vocal fatigue appear to include the neurophysiological and biomechanical effects of extended periods of phonation. It can also be a function of strategies used to adapt to extended periods of phonation, such as the use of excessive muscular tension and suboptimal vocal fold posturing. Studies that have attempted to identify observable responses that are reliably associated with vocal fatigue have met with limited success, but recent advances in research methodology are promising. This review addresses current approaches to the study of vocal fatigue, especially regarding subject selection, design variables, and measurement variables. Future studies should address the relationship between vocal fatigue and other voice disorders, differences in individual responses to vocal-loading tasks, and differential evaluation and management of the neuromuscular, biomechanical, and central processes involved in vocal fatigue.
Chatbots: Are they Really Useful?

Chatbots are computer programs that interact with users using natural lan- guages. This technology started in the 1960’s; the aim was to see if chatbot systems could fool users that they were real humans. However, chatbot sys- tems are not only built to mimic human conversation, and entertain users. In this paper, we investigate other applications where chatbots could be useful such as education, information retrival, business, and e-commerce. A range of chatbots with useful applications, including several based on the ALICE/AIML architecture, are presented in this paper.
Strategies in caring for women with postpartum psychosis--an interview study with psychiatric nurses.

AIM AND OBJECTIVE The aim of this study was to explore strategies in caring for women with postpartum psychosis used by nurses. BACKGROUND The most serious type of psychiatric illness in connection with childbirth is postpartum psychosis. Nearly two in 1000 newly delivered women are stricken by postpartum psychosis. Most of these patients need psychiatric care to recover. While earlier studies point to the need for psychiatric care, knowledge of specific nursing strategies in caring for postpartum psychosis patients remains limited. METHODS Interviews with 10 experienced psychiatric nurses were carried out, transcribed verbatim and an inductive content analysis was made. RESULT The main strategies for care found in this study were: (i) To create a patient-nurse relationship and (ii) To apply nursing therapeutic interventions. Presence, continuity and nurse-patient partnership contributed to create a relationship and incorporate the rest of the care team. To satisfy the patients' basic needs and feeling of security was the foundation of the nursing therapeutic interventions. Confirmation and giving hope were also used as nursing therapeutics as well as information to the patient and her relatives about her illness. CONCLUSION The conclusion of the study is that strategies used by nurses are a combination of general and psychiatric nursing approaches but the specificity in caring knowledge for caring patients with postpartum psychosis requires further development. RELEVANCE TO CLINICAL PRACTICE The result of the study indicates that it is important to organize patient care for postpartum psychosis with continuity and consistency and to support the nurse to create a relationship and therapeutic intervention with the patient. The present study shows the importance of further developing specific nursing theories that can be applied when caring for patients with postpartum psychosis. It also shows the need for further pedagogical education for mental health nurses.
On Some Problems of Mateescu Concerning Subword Occurrences

The paper investigates inference based on quantities |W|$_u$, the number of occurrences of a word u as a scattered subword of W. Parikh matrices recently introduced are useful tools for such investigations. We introduce and study universal languages for Parikh matrices. We also obtain results concerning the inference from numbers |W|$_u$ to W, as well as from certain entries of a Parikh matrix to other entries.
Functional and Structural Divergence of an Unusual LTR Retrotransposon Family in Plants

Retrotransposons with long terminal repeats (LTRs) more than 3 kb are not frequent in most eukaryotic genomes. Rice LTR retrotransposon, Retrosat2, has LTRs greater than 3.2 kb and two open reading frames (ORF): ORF1 encodes enzymes for retrotransposition whereas no function can be assigned to ORF0 as it is not found in any other organism. A variety of experimental and in silico approaches were used to determine the origin of Retrosat2 and putative function of ORF0. Our data show that not only is Retrosat2 highly abundant in the Oryza genus, it may yet be active in rice. Homologs of Retrosat2 were identified in maize, sorghum, Arabidopsis and other plant genomes suggesting that the Retrosat2 family is of ancient origin. Several putatively cis-acting elements, some multicopy, that regulate retrotransposon replication or responsiveness to environmental factors were found in the LTRs of Retrosat2. Unlike the ORF1, the ORF0 sequences from Retrosat2 and homologs are divergent at the sequence level, 3D-structures and predicted biological functions. In contrast to other retrotransposon families, Retrosat2 and its homologs are dispersed throughout genomes and not concentrated in the specific chromosomal regions, such as centromeres. The genomic distribution of Retrosat2 homologs varies across species which likely reflects the differing evolutionary trajectories of this retrotransposon family across diverse species.
Barriers to Mammography Among Inadequately Screened Women

Mammography use has increased over the past 20 years, yet more than 30% of women remain inadequately screened. Structural barriers can deter individuals from screening, however, cognitive, emotional, and communication barriers may also prevent mammography use. This study sought to identify the impact of number and type of barriers on mammography screening status, and to examine whether number and type of barriers are different for never-screened and off-schedule women. A total of 182 women aged 40 years or older completed a computer kiosk facilitated survey as part of a larger patient navigator intervention. Logistic regression analysis indicated that breast cancer knowledge predicted whether a woman had ever had a mammogram (odds ratio [OR] = 1.04, 95% confidence interval [CI] = 1.02-1.06, p = .0003), while the number of emotional, structural, and communication barriers predicted whether a woman was on-schedule for mammograms (OR = 0.79, 95% CI = 0.65-0.95, p = .0127). The results suggest that to increase the use of mammography at recommended regular intervals, interventions should be tailored toward current screening status.
What does body size mean, from the “plant's eye view”?

Abstract Alternative metrics exist for representing variation in plant body size, but the vast majority of previous research for herbaceous plants has focused on dry mass. Dry mass provides a reasonably accurate and easily measured estimate for comparing relative capacity to convert solar energy into stored carbon. However, from a “plant's eye view”, its experience of its local biotic environment of immediate neighbors (especially when crowded) may be more accurately represented by measures of “space occupancy” (S–O) recorded in situ—rather than dry mass measured after storage in a drying oven. This study investigated relationships between dry mass and alternative metrics of S–O body size for resident plants sampled from natural populations of herbaceous species found in Eastern Ontario. Plant height, maximum lateral canopy extent, and estimated canopy area and volume were recorded in situ (in the field)—and both fresh and dry mass were recorded in the laboratory—for 138 species ranging widely in body size and for 20 plants ranging widely in body size within each of 10 focal species. Dry mass and fresh mass were highly correlated (r 2 > .95) and isometric, suggesting that for some studies, between‐species (or between‐plant) variation in water content may be unimportant and fresh mass can therefore substitute for dry mass. However, several relationships between dry mass and other S–O body size metrics showed allometry—that is, plants with smaller S–O body size had disproportionately less dry mass. In other words, they have higher “body mass density” (BMD) — more dry mass per unit S–O body size. These results have practical importance for experimental design and methodology as well as implications for the interpretation of “reproductive economy”—the capacity to produce offspring at small body sizes—because fecundity and dry mass (produced in the same growing season) typically have a positive, isometric relationship. Accordingly, the allometry between dry mass and S–O body size reported here suggests that plants with smaller S–O body size—because of higher BMD—may produce fewer offspring, but less than proportionately so; in other words, they may produce more offspring per unit of body size space occupancy.
Asymptotic inference for partially observed branching processes

We consider the problem of estimation in a partially observed discrete-time Galton-Watson branching process, focusing on the first two moments of the offspring distribution. Our study is motivated by modelling the counts of new cases at the onset of a stochastic epidemic, allowing for the facts that only a part of the cases is detected, and that the detection mechanism may affect the evolution of the epidemic. In this setting, the offspring mean is closely related to the spreading potential of the disease, while the second moment is connected to the variability of the mean estimators. Inference for branching processes is known for its nonstandard characteristics, as compared with classical inference. When, in addition, the true process cannot be directly observed, the problem of inference suffers significant further perturbations. We propose nonparametric estimators related to those used when the underlying process is fully observed, but suitably modified to take into account the intricate dependence structure induced by the partial observation and the interaction scheme. We show consistency, derive the limiting laws of the estimators, and construct asymptotic confidence intervals, all valid conditionally on the explosion set.
Multi-flick: an evaluation of flick-based scrolling techniques for pen interfaces

Multi-flick, which consists of repeated flick actions, has received popular media attention as an intuitive and natural document-scrolling technique for stylus based systems. In this paper we put multi-flick to test, by designing several flick-based scrolling techniques. We first map out the de-sign space of multi-flick and identify mapping functions that make multi-flick a natural and intuitive technique for document navigation. In the first experiment we compare several multi-flick variations for navigating lists on three different devices -- a PDA, a tabletPC, and a large table. Our study shows that compound-multi-flick (CMF) is the most preferred technique and it is at least as fast, if not faster than the traditional scrollbar. In a follow-up experiment, we evaluate multi-flick for scrolling text-based documents. Results show that all implementations of multi-flick are as good as the scrollbar for short distances while CMF is the most preferred. We discuss the implications of our findings and present several design guidelines.
Prediction of Fasting Plasma Glucose Status Using Anthropometric Measures for Diagnosing Type 2 Diabetes

It is well known that body fat distribution and obesity are important risk factors for type 2 diabetes. Prediction of type 2 diabetes using a combination of anthropometric measures remains a controversial issue. This study aims to predict the fasting plasma glucose (FPG) status that is used in the diagnosis of type 2 diabetes by a combination of various measures among Korean adults. A total of 4870 subjects (2955 females and 1915 males) participated in this study. Based on 37 anthropometric measures, we compared predictions of FPG status using individual versus combined measures using two machine-learning algorithms. The values of the area under the receiver operating characteristic curve in the predictions by logistic regression and naive Bayes classifier based on the combination of measures were 0.741 and 0.739 in females, respectively, and were 0.687 and 0.686 in males, respectively. Our results indicate that prediction of FPG status using a combination of anthropometric measures was superior to individual measures alone in both females and males. We show that using balanced data of normal and high FPG groups can improve the prediction and reduce the intrinsic bias of the model toward the majority class.
Induction of circles of heterogeneous sizes in carcinogen-treated cells: two-dimensional gel analysis of circular DNA molecules

Extrachromosomal circular DNA molecules are associated with genomic instability, and circles containing inverted repeats were suggested to be the early amplification products. Here we present for the first time the use of neutral-neutral two-dimensional (2D) gel electrophoresis as a technique for the identification, isolation, and characterization of heterogeneous populations of circular molecules. Using this technique, we demonstrated that in N-methyl-N'-nitro-N-nitrosoguanidine-treated simian virus 40-transformed Chinese hamster cells (CO60 cells), the viral sequences are amplified as circular molecules of various sizes. The supercoiled circular fraction was isolated and was shown to contain molecules with inverted repeats. 2D gel analysis of extrachromosomal DNA from CHO cells revealed circular molecules containing highly repetitive DNA which are similar in size to the simian virus 40-amplified molecules. Moreover, enhancement of the amount of circular DNA was observed upon N-methyl-N'-nitro-N-nitrosoguanidine treatment of CHO cells. The implications of these findings regarding the processes of gene amplification and genomic instability and the possible use of the 2D gel technique to study these phenomena are discussed.
