Using Call Records to Understand Response in Panel Surveys

Panel surveys rely on repeated survey responses. Attrition may bias estimates, so identifying sampled units with a higher propensity to attrit may reduce bias. The literature suggests that call records from previous contacts are useful in identifying households inclined to attrit. In 2002, the U.S. Census Bureau developed an automated system to collect call record data after each contact attempt (the Contact History Instrument, or CHI). This paper examines the utility of feeding forward call history records to interviewers and whether contact history paradata can predict which cases will attrit from a panel survey. First, we compare refusal and noncontact rates for cases with access to previous quarter case history data to those without it. We also predict survey attrition using logistic regression models. This analysis first explores whether core paradata predicts attrition, then looks at including qualitative data in the models (concerns expressed by sampled units at the previous wave).
Low-Rank Laplacian-Uniform Mixed Model for Robust Face Recognition

Sparse representation based methods have successfully put forward a general framework for robust face recognition through linear reconstruction and sparsity constraints. However, residual modeling in existing works is not yet robust enough when dealing with dense noise. In this paper, we aim at recognizing identities from faces with varying levels of noises of various forms such as occlusion, pixel corruption, or disguise, and take improving the fitting ability of the error model as the key to addressing this problem. To fully capture the characteristics of different noises, we propose a mixed model combining robust sparsity constraint and low-rank constraint, which can deal with random errors and structured errors simultaneously. For random noises such as pixel corruption, we adopt a Laplacian-uniform mixed function for fitting the error distribution. For structured errors like continuous occlusion or disguise, we utilize robust nuclear norm to constrain the rank of the error matrix. An effective iterative reweighted algorithm is then developed to solve the proposed model. Comprehensive experiments were conducted on several benchmark databases for robust face recognition, and the overall results demonstrate that our model is most robust against various kinds of noises, when compared with state-of-the-art methods.
Lip reading : Japanese vowel recognition by tracking temporal changes of lip shape

In this paper, we propose a vision-based approach to recognize Japanese vowels. Traditional researches dealt with lip size, lip width and lip height, but our method deals with lip shape. Our method focus on temporal changes of lip shape, and we define new feature value to recognize vowels. There are a lot of conventional studies, but those studies’datasets are captured in specific environment such as well-lighted room and using lipsticks. However, we use Active shape models to extract lip area and calculate feature values. Therefore, our technique is not influenced by environment. And this paper describe the feature values are robust. We experimented with our approach and about 80% of average accuracy rate was obtained, and this rate is same as vowels recognition of Japanese who use lip reading. We conclude that our method helps speech recognition.
The Thick Orthotropic Plates Analysis Methods , Part I : A Review

As usage of plates, especially thick plates, are increased in structural and mechanical projects, the need for more precise plate analysis method increased, too. Designers look for a plate analysis method which can result in an exact stress-strain relationship with consideration of thickness effects, shear deformation and compressive deformation of plate across the thickness. This paper reviews the process of thick plate analysis method developments by describing a number of main plate analytical methods. Weak and strong points of each method are explained for each method.
Multiple flow direction algorithm based on extending neighborhood terrain

Flow direction algorithm is an important research area in hydrological analysis. In this paper, a novel flow direction algorithm with varied trend of extending neighborhood terrain is introduced, which is based on the basic principle of multiple flow direction algorithms. The basic idea of the methodology is that the flow partitioning proportion from the central grid to every neighboring grid should be related with the extending neighborhood terrain, and the influence of the extending neighborhood terrain for the flow condition should be considered comprehensively. At the last, the novel multiple flow direction algorithm is applied to an experimental region lie in Liaohe river basin. As the results, the new method can identify the river network accurately, and is a kind of relatively reasonable multiple flow direction algorithm.
LABOR FORCE TRANSITIONS: A COMPARISON OF UNEMPLOYMENT ESTIMATES FROM TWO LONGITUDINAL SURVEYS 1

Introduction The existence of micro-level panel t iara has lead to some major revisions in the way we think of labor market behaviors, bringing into question the very concept of unemployment as an unanticipated negative shock (e.g., Heckman and MaCurdy, 1980; MaCurdy, 1981; and Ashenfelter and Ham, 1979) and providing a novel perspective on the costs and even the definition of unemployment (e.g., Adams, 1985, and Abowd and Ashenfelter, 1981). The policy implications 2 are of such importance that we need to be very careful that they are not merely artifacts of the data due perhaps to measurement problems. Certain aspects of this issue hav.e already been investigated. A number of studies of the quality of selfreported unemployment, for example, have recently appeared in the literature (e.g., Bowers and ttorvath, 1984; or Poterba and Summers, 1985), and these present evidence of appreciable errors in reports of unemployment status and duration. Evidence of failure to report spells of unemployment is presented by Mathiowetz (1984), who finds that omission of reports of unemployment spells increases substantially with the length of time from the termination of the spell to the interview. While validation studies would offer the most reliable evidence on the quality of unemployment data, comparisons across different surveys can also be informative. The Survey of Income and Program Participation (SIPP) 3 and the Panel Study of Income Dynamics (PSID)* are two studies with similar unemployment information collected from comparable segments of the population, but with an important design difference. The SIPP data is collected on a more frequent basis than the PSID, and Mathiowetz's findings suggest that the more frequent interviewing schedule of the SIPP should result in more complete reporting of unemployment spells, especially short ones. The purpose of the present analysis is to compare reports of unemployment experiences for the July through December 1983 period obtained from the PSID and the SIPP. Duration of unemployment and transitions to employment are the focus since these labor force experiences are frequent enough during a short time span to allow relatively precise estimates with moderate sized surveys. The research will address two questions. First, do measures of the incidence and duration of unemployment differ between the studies? , and, second, do these differences result in different estimates of the parameters of a multivariate model of unemployment?

Preliminary Version Quantum programming with mixed states

In this paper we offer a programming approach to quantum computation using mixed states. Mixed-state quantum systems generalise standard (pure) quantum systems by allowing the state of the system to be a probabilistic distribution of pure states. We build on previous work by Aharonov et al. and generalise their results from quantum circuits to probabilistic (and quantum) programs.
The influence of anti-TNF agents on hemoglobin levels of patients with inflammatory bowel disease

Background—Anti-tumor necrosis factor (TNF) agents are an important component of inflammatory bowel disease (IBD) treatment but data on their influence on anemia, a frequent complication of IBD is limited. The aim of this study was to evaluate the effect of anti-TNF agents on hemoglobin (Hb) levels in a large IBD cohort. Methods—Prospectively collected demographic, clinical, laboratory and treatment data from IBD patients who started anti-TNF treatment at a tertiary referral center during the years 2010– 2012 were analyzed. Follow-up data including disease activity scores (Harvey-Bradshaw Index or ulcerative colitis activity index), quality of life scores [short IBD questionnaire (SIBDQ)] completed at each visit, and laboratory data were analyzed. Data from the year of anti-TNF initiation (year 0) and the following year (year 1) were compared. Results—A total of 430 IBD patients (324 with Crohn’s disease, 51.6% females) started antiTNF treatment. The prevalence of anemia and median Hb levels did not change between year 0 and year 1. Median SIBDQ was significantly improved at year 1 (p=0.002). IBD patients with anemia had significantly higher median Hb levels at year 1 compared to year 0 (p=0.0009). Hematopoietic response (increase of Hb ≥2 g/dL) was observed in only 33.6 % of the 134 anemic IBD patients, despite iron replacement being administered in 126 anemic patients (oral 77 %). Improvement in Hb levels was independently significantly correlated with change of CRP levels (p=0.04) and immunomodulators use (p=0.03). Conclusion—Anemia remains a significant manifestation of IBD one year after treatment with anti-TNF agents.
KNOWLEDGE PROTECTION AND KNOWLEDGE SHARING – BENEFITS AND PROBLEMS IN NETWORKED INNOVATION

In prior research, it has been stated that the strength of protection that a firm has against imitation of its core intangibles influences its performance. However, there are various mechanisms through which this can happen, as the availability and use of barriers to imitation offers quite different, even opposing, opportunities to utilize the intangibles belonging to an individual organization. Especially the increasing tendencies to collaborate in innovation activities have opened up new possibilities, although new challenges have also emerged as a result of increasing networking. This study examines especially knowledge sharing and protection as two elements strongly present in networked innovation. The empirical evidence from 291 companies suggests that the strong appropriability regime (i.e. “protective fence” improving controllability of intangibles) contributes to both lengthening the imitation lag and facilitating knowledge exchange between organizations. The findings further illustrate that of these two, knowledge sharing is the one yielding better innovation performance, whereas imitation lags contribute to firm success in terms of profitability and increased turnover. It can be thus concluded that an integrative perspective, rather than simply choosing between two (seemingly) opposing strategies enables a firm to perform better, especially in the networked environment.
Object Recognition Approach Based on Generalized Hough Transform and Color Distribution Serving in Generating Arabic Sentences

The recognition of the objects contained in images has always presented a challenge in the field of research because of several difficulties that the researcher can envisage because of the variability of shape, position, contrast of objects, etc. In this paper, we will be interested in the recognition of objects. The classical Hough Transform (HT) presented a tool for detecting straight line segments in images. The technique of HT has been generalized (GHT) for the detection of arbitrary forms. With GHT, the forms sought are not necessarily defined analytically but rather by a particular silhouette. For more precision, we proposed to combine the results from the GHT with the results from a calculation of similarity between the histograms and the spatiograms of the images. The main purpose of our work is to use the concepts from recognition to generate sentences in Arabic that summarize the content of the image. Keywords—Recognition of shape, generalized hough transformation, histogram, Spatiogram, learning.
1 Characterization of UDP-glucuronosyltransferases 2 and the potential contribution to nicotine tolerance in 3 Myzus persicae 4

Uridine diphosphate (UDP)-glycosyltransferases (UGTs) are major phase II 10 detoxification enzymes involved in glycosylation of lipophilic endobiotics and xenobiotics, 11 including phytoalexins. Nicotine, one of the most abundant secondary plant metabolites in tobacco, 12 is highly toxic to herbivorous insects. Plant-herbivore competition has been the major impetus for 13 evolution of large superfamilies of UGTs and other detoxification enzymes. However, UGT 14 functions in green peach aphid (Myzus persicae) adaptation are unknown. In this study, we show 15 that UGT inhibitors (sulfinpyrazone and 5-nitrouracil) significantly increased nicotine toxicity in M. 16 persicae nicotianae, suggesting that UGTs may be involved in nicotine tolerance. In total, 101 UGT 17 transcripts identified in the M. persicae genome/transcriptome were renamed according to the UGT 18 Nomenclature Committee guidelines and grouped into 11 families, UGT329, UGT330, UGT339, 19 UGT341-UGT345, and UGT348-UGT350, with UGT344 containing the most (57). Ten UGTs 20 (UGT330A3, UGT339A2, UGT341A6, UGT342B3, UGT343C3, UGT344D5, UGT344D8, UGT348A3, 21 UGT349A3 and UGT350A3) were highly expressed in M. persicae nicotianae compared to M. persicae 22 sensu stricto. UGT330A3/UGT344D5/UGT348A3/UGT349A3 Knockdown of four UGTs 23 (UGT330A3,UGT344D5, UGT348A3 and UGT349A3)significantly increased M. persicae nicotianae 24 sensitivity to nicotine, suggesting that UGT expression in this subspecies may be associated with 25 nicotine tolerance and thus host adaptation. This study reveals possible UGTs relevant to nicotine 26 adaptation in tobacco-consuming M. persicae nicotianae, and the findings will facilitate further 27 validation of the roles of these UGTs in nicotine tolerance. 28
A COMPARISON OF ESTIMATORS FOR THE VARIANCE OF REGRESSION-TYPE ESTIMATORS IN A FINITE POPULATION

This paper is an extension of an earlier paper West (1983), which looked at ratio-type estimators for the total of a finite population. Now estimators are developed for the variance of the error which results from specific estimators of the total. ~he results of a theoretical and empircial investigation are presented. The investigations which led to this paper and the earlier paper began in connection with a modernization project for the Bureau of Labor Statistics program that provides monthly estimates of employment, hours and earnings of workers on nonagricultural establishment payrolls. In this program, population employment counts are obtained once a year from Unemployment Insurance administrative records. Monthly estimates of change between the population counts are obtained from a large voluntary monthly mail survey, known as the Current Employment Survey (CES) or 790 Survey because of its schedule number. The CES data are obtained from cooperating establishments on a voluntary mail "shuttle" schedule. The main variable is employment and that is the only one cons idered in th is paper. The estimators that were considered for the total (West, 1983) were developed from the point of view of probability models. The variance estimators in this paper are also hssed on probability models. Recent theoretical and empirical studies, such as Royall and Cumberland (1981), have shown the benefits of probability models in finite population inference. These studies show the value of approaches in which models describe the relat ionsh ips among variables of interest, and inferences are guided by these relationships. The sampling plan is thus relieved of the burden of generating the probability distribution on which inferences are based, and its purpose is seen to be the selection of a good sample. It ~as shown in West (1981) that the CES data do indeed follow a linear model. In Section 2 the most promising models and the resulting estimators for the total are reviewed. In Section 3, five variance estimators are developed for a number of different total estimators. Using a real population, an empirical investigation ~as undertaken to examine the different estimators for the population total at each month and the different estimators of their variance. The empirical investigation is described in Section 4 and the results are presented in Section 5.
In Silico Identification of Interaction between Ageing and Cardiovascular Disease Genes

Heart is the central organ that pumps pure blood to whole body through blood vessels. This circulation system involves functioning of large number of genes that interacts for proper functioning. Any malfunctioning of single gene leads to the cardiovascular diseases (CVDs) Aging is an inevitable part of life and unfortunately the risk of CVDs increases with ageing. Although numerous studies were carried on cardiovascular diseases that considered both young and aged humans, but still there are many unanswered questions as to how the genetic pathways that regulate aging influence cardiovascular disease and vice versa. Therefore, this is of great interest to identify the interaction between cardiovascular diseases and ageing genes. Genes for CVDs and ageing were collected from various databases and a network was created for their common genes. Network in analyzed to find the interaction between ageing and cardiovascular disease genes.
The “ Digital Divide , ” Social Media , and Education-Related Outcomes

Various scholars and practitioners advocate that instructors incorporate social media platforms such as Facebook and Twitter in higher education to enhance positive education-related outcomes. The push for integration relates to the perceived educational needs of the current generation of students who are enrolled in higher education and are known as “digital natives. ” However, this literature review illustrates that the oft-cited divide between digital natives and digital immigrants, which is used as rationale for course enhancement via social media, is specious. In addition, extant research suggests that the use of Facebook and Twitter in higher education is correlated with at least three positive outcomes: an increase in student engagement; an increase in student perceptions of instructor credibility; and an increase in student perceptions of instructor immediacy. However, research about the effects of supplementing traditional in-class interaction with Facebook and Twitter is in its infancy. The authors conclude that the integration of social media into higher education should be undertaken with care because Millennial students may not be as technologically-savvy as originally thought, and because extant studies about the benefits of integrating social media into higher education are limited.
Modeling of Synchronous Machines Including Voltage Regulation

Synchronous machines are intensively used as generators due to their very good voltage and frequency regulation characteristics. To study the control of the generated active and reactive power it is necessary to have a very accurate mathematical dynamic models to implement efficient simulations. This article deals with the modelling of synchronous generators (machines) including their voltage regulation systems for the purposes of voltage transient analysis. There is a principle of mathematical modelling of the synchronous machine, including its voltage regulation system described in the first part of the article. The modelling of the synchronous machine and its excitation system response to the rapid load changes, in particular to the rapid reactive power changes, is based on real measured data, according to the machine parameters and the response of recorded voltage and current changes on its terminals. Described methodology does not follow standard procedures for modelling the excitation systems and is based on the analytical solution of the differential equations. Verification of the created mathematical model is performed by comparing simulated and real measured data, which is realized in the second part of the article. Streszczenie.

MECHANICAL PROPERTIES OF FRICTION STIR WELDED DISSIMILAR METALS

The aim of present study was to analyse the influence of the microstructures and mechanical properties of friction stir welded butt joint of 6101 aluminium alloy and pure copper plates in 3 mm thickness. With this aim, welds were produced using Tungsten Carbide tools, with a cylindrical pin tool having 5 mm and 20 mm diameter of pin and shoulder respectively. Copper plates were kept in advancing side of weld. The microstructure of weld were studied by optical microscopy and grain size in different regions were analyze. Vicker’s microhardness test (as per ASTM E384-89) were done in transverse direction of weld to check the hardness distribution in weld nugget. Transverse tensile test (as per ASTM E8 M) were performed to evaluate the weakest portion of weld joints. Scanning Electron Microscope were used to observe the fracture surfaces. EDAX analysis were done to find out the mixing characteristic of two metals.
The Declining Middle : Political Reactions to Occupational Change

This article investigates the political consequences of occupational change in times of rapid technological advancement and sheds light on the economic and cultural roots of right-wing populism. A growing body of research shows that the disadvantages of a transforming employment structure are strongly concentrated among semiskilled routine workers in the lower middle class. It is argued that individual employment trajectories and relative shifts in the social hierarchy are key to better understand recent political disruptions. A perception of relative economic decline among politically powerful groups — not their impoverishment — drives support for conservative and, especially, right-wing populist parties. Individual-level panel data from three post-industrial democracies and an empirical strategy tailored to the estimation of dynamic causal e ects demonstrate this relationship. Additional evidence from original survey data lends credence to the proposed mechanism. The ndings imply that "more welfare" will be an ine ective remedy against the ascent of right-wing populism.
