A robust web personal name information extraction system

Personal information extraction, which extracts the persons in question and their related information (such as biographical information and occupation) from web, is an important component to construct social network (a kind of semantic web). For this practical task, two important issues are to be discussed: personal named entity ambiguity and the extraction of personal information for a specific person. For personal named entity ambiguity, which is a common phenomenon in the fast growing web resource, we propose a robust system which extracts lightweight features with a totally unsupervised approach from broad resources. The experiments show that these lightweight features not only improve the performances, but also increase the robustness of a disambiguation system. To extract the information of the focus person, an integrated system is introduced, which is able to effectively re-use and combine current well-developed tools for web data, and at the same time, to identify the expression properties of web data. We show that our flexible extraction system achieves state-of-the-art performances, especially the high precision, which is very important for real applications.     

The impact of governance structure on firm performance: An application to the German water distribution sector

This paper investigates the impact of governance structure on firm performance (i.e., retail prices) using a database of 765 German water suppliers. Controlling for scale economies as well as technical and structural characteristics, we find that private sector participation is accompanied with higher retail prices. Furthermore, Eastern states on average feature higher prices mirroring significant investments during the past two decades as well as network over-dimension. Assuming that managers make strategic decisions (e.g., governance form) not randomly but rather decide based on expectations of how their choices affect future performance, we test for this self-selection applying a two-stage model.     

Errors enacted during endoscopic surgery-a human reliability analysis

The aim of the study was to document the nature and incidence of surgical errors enacted during laparoscopic surgery in order to direct future research and surgical training. A modified Human Reliability Analysis (HRA) approach, based on direct observation, was adopted to categorise and record errors encountered during the practice of laparoscopic cholecystectomy. This study confirmed the applicability and usefulness of an observational methodology in the assessment of human error in endoscopic surgical performance. The study identified aspects of the design and usage of instruments, surgical training and the differences between tasks which needed further directed research in order to identify underlying performance shaping factors (PSFs) and so reduce error rates.     

Measuring factors affecting grip strength in a Taiwan Chinese population and a comparison with consolidated norms

We inquire whether assessment of an individual's upper limb function may be improved by using specific regional norms rather than consolidated global norms. Grip strengths were measured in a sample of 482 adults across Taiwan, and compared with consolidated norms. To ensure comparable conditions, our procedures were those recommended by the American Society of Hand Therapists (ASHT). Overall the mean grip strength of our sample was significantly (male 25%, female 27%) lower than consolidated norms derived from largely Caucasian populations. We investigated variables that might relate to this divergence. Results of ANOVA and stepwise multiple regression analysis showed that gender, age and palm length were effective predictors in grip strength. A regression equation was derived. When other variables were matched, palm length appeared an important discriminating factor. Further anthropometric and socio-economic factors also need investigation. Specific regional norms should provide more accuracy for ergonomists and health workers assessing an individual's upper limb function, and may avoid errors in appraisal. This paper suggests grip strength values for Taiwan.

Judicial Application of Daubert to Psychological Syndrome and Profile Evidence: A Research Note.

The authors present previously unreported results from a nationwide survey (N=325) of state trial judges (S. I. Gatowski et al., 2001) that was conducted pre-Kumho. The authors report how the 1993 Daubert guidelines were applied to psychological syndrome and profile evidence, and the impact of the decision on the admissibility of such evidence. They found that judges' views of and experience with psychological testimony varied widely and that most judges neither understood nor applied the more technical Daubert guidelines, such as falsifiability and error rate, when assessing psychological evidence. Overall, the findings suggest that Daubert's impact on the admissibility of psychological syndrome and profile testimony is negligible and that most judges are more comfortable with pre-Daubert standards when this type of testimony is proffered.

Flexible Bytecode for Linking in .NET

Dynamic linking in modern execution environments like .NET is considerably more sophisticated than in the days of C shared libraries on UNIX. One aspect of this sophistication is that .NET assemblies embed type information about dynamically linked resources.This type information implicitly represents compile-time assumptions about the resources available at run-time. However, the resources available at run-time may differ from those available at compile-time. For example, the execution environment on a mobile phone might provide fewer, simpler classes than on a desktop PC. As bytecode cannot adapt to its execution environment, component reuse is restricted and development costs are increased.We have designed and implemented a “flexible” dynamic linking scheme that binds bytecode as late as possible to the assemblies and classes available in a .NET execution environment. We describe the scheme's integration with the .NET linking infrastructure, review important design decisions and report on experiences with the “Rotor” shared source version of .NET.

Multigene Profiling of Circulating Tumor Cells (CTCs) for Prognostic Assessment in Treatment-Naïve Metastatic Hormone-Sensitive Prostate Cancer (mHSPC)

The substantial biological heterogeneity of metastatic prostate cancer has hindered the development of personalized therapeutic approaches. Therefore, it is difficult to predict the course of metastatic hormone-sensitive prostate cancer (mHSPC), with some men remaining on first-line androgen deprivation therapy (ADT) for several years while others progress more rapidly. Improving our ability to risk-stratify patients would allow for the optimization of systemic therapies and support the development of stratified prospective clinical trials focused on patients likely to have the greatest potential benefit. Here, we applied a liquid biopsy approach to identify clinically relevant, blood-based prognostic biomarkers in patients with mHSPC. Gene expression indicating the presence of CTCs was greater in CHAARTED high-volume (HV) patients (52% CTC_high) than in low-volume (LV) patients (23% CTC_high; * p = 0.03). HV disease (p = 0.005, q = 0.033) and CTC presence at baseline prior to treatment initiation (p = 0.008, q = 0.033) were found to be independently associated with the risk of nonresponse at 7 months. The pooled gene expression from CTCs of pre-ADT samples found AR, DSG2, KLK3, MDK, and PCA3 as genes predictive of nonresponse. These observations support the utility of liquid biomarker approaches to identify patients with poor initial response. This approach could facilitate more precise treatment intensification in the highest risk patients.
