Comparison of Polymerase Chain Reaction, Monoclonal Antibody Based Enzyme Immunoassay, and Cell Culture for Detection of Chlamydia trachomatis in Genital Specimens

An enzyme immunoassay (EIA; AntigEnz Chlamydia; Northumbria Biologicals, Northumberland, United Kingdom) and a polymerase chain reaction (PCR) assay (Genemed Biotechnologies, San Francisco, CA) were evaluated for the detection of Chlamydia trachomatis in urogenital specimens. Of 324 specimens, 23 were positive by cycloheximide-treated McCoy's cell culture method. Of 23 culture-positive specimens, 20 and 22 were found to be positive by EIA and PCR, respectively. Among 301 culture-negative samples, 4 were found to be positive by both PCR and EIA, 2 were PCR-positive and EIA-negative, and 3 PCR-negative and culture-negative specimens were found to be positive by EIA. In comparing nonculture methods with cell culture technique, combined sensitivities of 87.0% (90.9% in men and 83.3% in women) and 95.6% (90.9% in men and 100% in women), and specificities of 97.7% (99.4% in men and 95.7% in women) and 98.0% (99.4% in men and 96.5% in women) are achieved by EIA and PCR, respectively. The PCR proved to be the more sensitive of these two nonculture methods, and it can be used for the rapid diagnosis of C. trachomatis urogenital infection.
Black–Litterman with a Factor Structure Applied to Multi-Asset Portfolios

In this article, the author directly incorporates a standard factor structure into the Black–Litterman (BL) framework that can be applied to a wide array of mean–variance optimization problems, but it is especially useful for multi-asset portfolio construction. The author compares the BL model with a direct factor structure to the BL model with view portfolios employed in the existing literature. He argues that when tactical views are quantitatively derived, using a direct factor structure can be applied to a broader set of investment problems than integrating factors via view portfolios. The two frameworks are quite similar when applied to traditional quantitative stock selection portfolio construction. However, the direct factor approach can easily handle two situations that often occur in multi-asset portfolio construction that the view portfolio approach cannot: when the number of factors is greater than the number of assets (e.g., market-timing models) and when uncertainty in asset residuals is heterogeneous. In addition, the author provides the fundamental assumptions with clean notation that underpin the BL model.
Analysis of visitor's behavior from web log using web log expert tool

Web usage mining is a data mining technique. There are large amount of data are stored on the internet. When user search any particular information by search engine like Google, Bing etc. is very difficult because the complexity of web pages is increases day by day. Web usage mining plays an important role to solve this problem. In web usage mining we are creating a suitable pattern according to the user's visiting behavior. The goal of this paper is to implement a web log Expert tool on web server log file (an educational institution web log data) to find the behavioral pattern and profiles of users interacting with a web site. The web mining usage pattern of an Technical Institution web data. Web related data is coteries in to three parts namely web log, access log, error log and proxy log data and collect the data in web server and implemented a web log expert. Our experimental results help to predict and identify the number of visitor for the website and improve the website usability. The web related log data are three types, namely proxy log data, web log data, and error log data. We exploration the activity statistic by daily based hourly based week and monthly based report of web usage pattern. The web usage mining is playing an important role to improve the availability of information of your web site.
The Contact and Mobility Networks of Mexico City

Mexico City, the largest city in Mexico, is also one of the largest cities in the world. It has over 9 million inhabitants and concentrates the vast majority of government and business centers. In this work we describe al-gorithms that use anonymized location data from mobile devices to construct Mexico City’s contact and mobility networks aiming to help the analysis of the city’s complexity by understanding movement and physical interaction patterns between its inhabitants. We show the eﬀectiveness and usefulness of our approach by building networks with data collected performing a general descriptive analysis on them. We found that contact networks in Mexico City are very sparse, charac-terized by a largest connected component, and with a heavy-tailed degree distribution. On the other hand, we observed that paths conformed by the highest-degree nodes of mobility networks resemble Mexico City’s street network; moreover, we found interesting qualitative diﬀerences in the degree distribution of these networks between weekends and weekdays. We present these results along with the release of contact and mobility networks.
Experimental research for target tracking in single frequency network based passive radar

Recently single frequency network (SFN) has been adopted by most of modern digital TV and broadcast systems. In SFN, all illuminators transmit the same signal at the same frequency simultaneously. The same target would generate multiple simultaneous measurements in SFN-based passive radar. In this paper, we use an association hypothesis decision method to deghost during tracking initiation and use a 2-dimensional assignment approach to solve the problem of measurement-to-transmitter association during tracking maintain. Finally, the SFN-based passive radar system and a field experiment conducted by Wuhan University is described, together with results from field trials for aircraft tracking.
VASCULAR CALCIFICATION IN PATIENTS WITH KIDNEY DISEASE: Techniques and Technologies to Assess Vascular Calcification

Cardiovascular calcification (CV) is highly prevalent in chronic kidney disease stage V and has been associated with an increased risk for all‐cause as well as cardiovascular mortality. A number of noninvasive imaging techniques are available to screen for the presence of CV—plain x‐rays of the abdomen and extremities to identify macroscopic calcifications of aorta and peripheral arteries; echocardiography for assessment of valvular calcification; two‐dimensional ultrasound for calcification of carotid arteries, femoral arteries and aorta, and computed tomography technologies that constitute the gold standard for quantification of coronary artery and aorta calcification. Some of these modalities are also useful to monitor calcification progression and to assess the effect of different therapeutic strategies directed at modifying calcification progression. In this article we review the strengths and limitations of the most common noninvasive techniques employed for the imaging of vascular calcification.
The Empirical Study of House-price Fluctuations on the Impact of Total Factor Productivity of Manufacturing in China—Based on the Perspective of Misallocation of Resources

The paper establishes theoretical and empirical model that measured and analyzed the impact of distortions of factor price, caused by irrational prosperity of China’s real estate, on misallocation of capital, labor and distortion of overall TFP in manufacturing enterprises during the periods of 2007 to 2016. The main conclusions obtained are at followings: 1) Manufacturing enterprises had significant and varying degree of distortions of capital, labor and overall TFP on three levels of national overall, different regions and ownership systems; 2) Rising real estate prices could obviously cause misallocation of resources and reduce the growth rate of TFP in manufacturing; 3) If the misallocation of resources were eliminated, the TFP would receive a highly increase of 20%-30%. The degree of influence of the virtual economy on the real economy is exactly what China and the countries with related problems need to study in depth. This study will make up the gaps in this research.
The histidine triad protein Hint1 interacts with Pontin and Reptin and inhibits TCF–β-catenin-mediated transcription

Pontin and Reptin previously were identified as nuclear β-catenin interaction partners that antagonistically modulate β-catenin transcriptional activity. In this study, Hint1/PKCI, a member of the evolutionary conserved family of histidine triad proteins, was characterised as a new interaction partner of Pontin and Reptin. Pull-down assays and co-immunoprecipitation experiments show that Hint1/PKCI directly binds to Pontin and Reptin. The Hint1/PKCI-binding site was mapped to amino acids 214-295 and 218-289 in Pontin and Reptin, respectively. Conversely, Pontin and Reptin bind to the N-terminus of Hint1/PKCI. Moreover, by its interaction with Pontin and Reptin, Hint1/PKCI is associated with the LEF-1/TCF–β-catenin transcription complex. In this context, Hint1/PKCI acts as a negative regulator of TCF–β-catenin transcriptional activity in Wnt-transfected cells and in SW480 colon carcinoma cells as shown in reporter gene assays. Consistent with these observations, Hint1/PKCI represses expression of the endogenous target genes cyclin D1 and axin2 whereas knockdown of Hint1/PKCI by RNA interference increases their expression. Disruption of the Pontin/Reptin complex appears to mediate this modulatory effect of Hint1/PKCI on TCF–β-catenin-mediated transcription. These data now provide a molecular mechanism to explain the tumor suppressor function of Hint1/PKCI recently suggested from the analysis of Hint1/PKCI knockout mice.
Evolutionary design of lifting scheme wavelet-packet adaptive filters for elevator fault detection

An evolutionary-based procedure for designing adaptive filters based on second-generation wavelet (lifting scheme) packet decomposition for industrial fault detection is presented. The proposed procedure is validated by an experimental case study for induction motor fault diagnosis in an elevator system. Preliminary results on two typologies of faults, broken rotor bars and static air gap eccentricity, are discussed by showing encouraging performance.
A mobile agent infrastructure for terminal, user, and resource mobility

The telecommunication and the Internet scenarios have pointed out the possibility of accessing resources and services while moving in open distributed global systems. Mobility should allow users to access services and to maintain their preferred working environment independently of their current point of attachment, and has motivated the investigation of new models and solutions. The mobile agent technology is intrinsically suitable to describe, model and implement mobility. The paper describes how a mobile agent framework, called SOMA, can provide an infrastructure to support not only the traditional concepts of terminal and user mobility but also the mobility of resources in general. SOMA permits terminal mobility by introducing the mobile place abstraction that represents a mobile host for agent execution, and user mobility by supporting the virtual home environment service. SOMA supports resource mobility via the resource discovery service that can preserve client/server relationships among SOMA resources and users independently of current positions. The paper also gives experimental results about the costs associated with the main mechanisms for supporting terminal, user, and resource mobility.
Kettlebell training for musculoskeletal and cardiovascular health: a randomized controlled trial.

OBJECTIVE The aim of this trial was to investigate the effectiveness of a worksite intervention using kettlebell training to improve musculoskeletal and cardiovascular health. METHODS This single-blind randomized controlled trial involved 40 adults from occupations with a high prevalence of reported musculoskeletal pain symptoms (mean age 44 years, body mass index 23 kg/m², 85% women, with pain intensity of the neck/shoulders 3.5 and of the low back 2.8 on a scale of 0-10). A blinded assessor took measures at baseline and follow-up. Participants were randomly assigned to training--consisting of ballistic full-body kettlebell exercise 3 times per week for 8 weeks--or a control group. The main outcome measures were pain intensity of the neck/shoulders and low back, isometric muscle strength, and aerobic fitness. RESULTS Compared with the control group, pain intensity of the neck/shoulders decreased 2.1 points [95% confidence interval (95% CI) -3.7- -0.4] and pain intensity of the low back decreased 1.4 points (95% CI -2.7- -0.02) in the training group. Compared with the control group, the training group increased muscle strength of the trunk extensors (P<0.001), but not of the trunk flexors and shoulders. Aerobic fitness remained unchanged. CONCLUSIONS Worksite intervention using kettlebell training reduces pain in the neck/shoulders and low back and improves muscle strength of the low back among adults from occupations with a high prevalence of reported musculoskeletal pain symptoms. This type of training does not appear to improve aerobic fitness.
Claiming the corner office: Female CEO careers and implications for leadership development

Drawing on evidence from a unique data set of in-depth qualitative interviews with 12 female CEOs (and 139 male CEOs) of global corporations, we explore what enables some women to become CEOs. By drawing on our data from male and female CEOs, we set the scene by comparing the advice they would give to young women as they start their careers. We then focus the rest of our article on the experiences and career trajectory of the 12 female CEOs. We make three theoretical contributions: We identify, at the individual level, how women can take active ownership of their careers as part of a self-acceptance process; how they can embrace gynandrous leadership as part of a self-development process where both feminine and masculine leadership behaviors are embraced, with the feminine being dominant to help move beyond gender stereotypes, and finally, how they translate leadership—rather than combine—gender-based behaviors as part of a self-management process to develop their unique leadership style. For each of these theoretical contributions at the individual level, we also provide two practical recommendations for HR practice and policy, one relating to the intraorganizational context and the second having institutional-level implications. We conclude by discussing implications for future research.
The effects of an education-leave program on educational attainment and labor-market outcomes

ABSTRACT I study the effect of an education-leave subsidy for the employed on labor-market outcomes and educational attainment using Finnish administrative linked employer-employee panel data and matching methods. The adult education allowance is available to employees with at least eight years of work experience and allows them to take a leave for 2–18 months to participate in an education program. I find large positive treatment effects on educational attainment and changing occupation. The treatment effects on earnings and employment are negative during the lock-in period and close to zero afterward. The effects are more positive for the less educated.
Maximising sensitivity for detecting changes in protein expression: Experimental design using minimal CyDyes

DIGE is a powerful tool for measuring changes in protein expression between samples. Here we assess the assumptions of normality and heterogeneity of variance that underlie the univariate statistical tests routinely used to detect proteins with expression changes. Furthermore, the technical variance experienced in a multigel experiment is assessed here and found to be reproducible within‐ and across‐sample types. Utilising the technical variance measured, a power study is completed for several ‘typical’ fold changes in expression commonly used as thresholds by researchers. Based on this study using DeCyder, guidance is given on the number of gel replicates that are needed for the experiment to have sufficient sensitivity to detect expression changes. A two‐dye system based on utilising just Cy3 and Cy5 was found to be more reproducible than the three‐dye system. A power and cost‐benefit analysis performed here suggests that the traditional three‐dye system would use fewer resources in studies where multiple samples are compared. Technical variance was shown to encompass both experimental and analytical noise and thus is dependent on the analytical software utilised. Data is provided as a resource to the community to assess alternative software and upgrades.
From International Law and International Relations to Law and World Politics

Political scientists — primarily in the discipline’s international relations subfield — have long studied international law. This article identifies five stages of political science research on international law, including the current interdisciplinary international law and international relations (IL/IR) stage, and it reviews three trends in political science research that constitute an emerging sixth stage of interdisciplinary scholarship: a law and world politics (L/WP) stage. First, moving beyond the “IL” in IL/IR scholarship, international relations scholars are increasingly studying domestic law and domestic courts — not only their foundational role in supporting international law and international courts but also their direct role in core areas of international relations, including international conflict and foreign policy. Second, moving beyond the “IR” in IL/IR scholarship, political scientists are adapting their research on international law to the broader world politics trend in political science by studying types of law — including extraterritoriality, conflict of laws, private international law, and the law of transnational commercial arbitration — that govern the transnational activity of private actors and can either support or hinder private global governance. Third, moving beyond the domestic- international divide, political scientists are increasingly rejecting “international law exceptionalism,” and beginning to take advantage of theoretical convergence across the domestic, comparative, and international politics subfields to develop a better general understanding law and politics. This article’s main goal is to map out L/WP scholarship by examining these three trends. It also aims to facilitate further L/WP research by describing several areas of law, including foreign relations law, conflict of laws, transnational commercial arbitration, and international investment law, that may be unfamiliar to some political scientists, and explaining why they are relevant to international relations and to world politics more broadly. The article proceeds in five sections. The first two sections provide background by clarifying the definition of international law (Section 1) and briefly surveying the historical evolution of political science research on international law (Section 2). The last three sections review more recent scholarship to illustrate how L/WP research is moving beyond international law (Section 3), beyond international relations (Section 4), and beyond international law exceptionalism (Section 5).
Coping with the stress of premature labor.

UNLABELLED Premature birth, the leading cause of perinatal morbidity and mortality in the United States affects between 8% and 12% of all live births. Approximately 80% of premature births are proceeded by premature labor. Significant progress has been made in the physical treatment of premature labor; however, the psychological cost to women being treated needs further study. My purpose in conducting this study was to assess the stress experienced by women treated at home for premature labor and to examine methods used by the women to cope. The theoretical framework was provided by Lazarus's model of Stress, Coping, and Emotion. A total of 50 women participated. Twenty responded to a questionnaire that included the Perceived Stress Scale (PSS) and the Ways of Coping Questionnaire only, 10 were interviewed only, and 20 completed the questionnaire and the interview. RESULTS The women reported experiencing a moderate amount of stress. Their mean stress score was 26.75, just below the mean for the instrument (M = 28) and slightly less than the stress score of 27.52 reported by women experiencing a "normal" pregnancy. Appraisal was assessed by analyzing the data from the interviews. The women appraised their situation as both threatening and challenging. They described their emotional response most frequently as frustration because of fear concerning the pregnancy outcome, loss of control over their life, and inability to perform their usual roles of mother, wife, and worker. The women reported on the Ways of Coping Questionnaire that they used strategies from three subscales to cope with the premature labor. Those subscales were Seeking Social Support, Planful Problem-Solving, and Positive Reappraisal.
Environment Conservation toward Local Culture on Belief

This study is the result of research conducted on environmental conservation based on local culture as a symbolic study and reality of community behavior patterns. This study explores local knowledge in conserving and preventing environmental degradation, and efforts adopted by customary institutions and formal subdistrict government in preserving the environment. In this research, the approach used is ethnographic with the technique of tracing data. The grand theories used in exposing this problem are Max Weber's theory of social action, the theory of Behaviors, and Symbolic theory. This study found that Dewata Sewwae believers in the location targeted by the Tolotang Bacukiki symbolically are such communities that uphold familiarity with nature, and regard that the environment is part of their lifestyle. Similarly, by this research, the role of adat institutions and subdistrict governance in preserving the environment (forest) is significant. By the existence of customary tools becoming institutions that curb every act of forests exploitation. Similarly, the village level government is a formal institution that can serve as a medium for mediation between indigenous peoples' interests and formal rules relating to efforts to protect forest conservation.
The development of evidence-based nursing interventions: methodological considerations.

BACKGROUND The call for evidence-based practice presents numerous challenges to nurses who are responsible for developing interventions and expanding the associated knowledge base. The challenge is compounded because there is limited literature concerning development of interventions and their evidence base. AIM The purpose of this article is to present a model that has been successfully used to guide the process of developing and testing complex nursing interventions, especially those in which the experience of the client plays an important role. DISCUSSION The model consists of four stages: problem definition, accumulation of building blocks for intervention design, intervention design and intervention validation. Each stage is described and examples from research studies are presented. Specific attention is given to the manner in which the model allows for the accumulation of empirical evidence and theory development during the development process. CONCLUSIONS Use of the model could facilitate effective communication among nurses, researchers and educators when discussing the development and testing of nursing interventions.
