Examining Consistency of Responses in Self-Reports Using Content Analysis.

Content analysis was used to examine the consistency of responses in self-report data obtained by a semi-structured conversational interview. It was hypothesized that a majority of the seemingly inconsistent responses would prove to be consistent when seen from the respondents' points of view. The sample consisted of 215 female homicide offenders incarcerated in New York State correctional facilities or on active parole supervision in New York City. Results indicate that of the 24 respondents initially identified as having inconsistent responses, only one was regarded as inconsistent after the content analysis was performed and a coding scheme was developed to examine the apparent inconsistency from the respondent's point of view. The coding scheme developed also predicted homicide-related variables more effectively than did the original coding scheme developed for this sample. Suggestions for improving the construction of interview questions are also presented. (Contains 3 tables and 22 refelences.) (Author)
Content-based image retrieval by dictionary of local feature descriptors

This paper describes a novel method of image key-point descriptor indexing and comparison used to speed up the process of content-based image retrieval as the main advantage of the dictionary-based representation is faster comparison of image descriptors sets in contrast to the standard list representation. The proposed method of descriptor representation allows to avoid initial learning process, and can be adjusted taking into consideration new examples. The presented method sorts and groups components of descriptors in the process of the dictionary creation. The ordered structure of the descriptors dictionary is well suited for quick comparison of images by comparing their dictionaries of descriptors or by comparing individual descriptors with the dictionary. This allows to skip a large part of operations during descriptors comparison between two images. In contrast to the standard dictionary, our method takes into account the standard deviation between the image descriptors. This is due to the fact that almost all descriptors generated for the points indicating the same areas of the image have different descriptors. Estimation of the similarity is based on the determined value of the standard deviation between descriptors. We assume that proposed method can speed up the process of descriptor comparison. It can be used with many solutions which require high-speed operations on the image e.g. robotics, or in software which computes panoramic photography from scrap images and in many others.
Overexpression and properties of wild-type and Tyr437His mutated myocilin in the eyes of transgenic mice.

PURPOSE To obtain experimental in vivo information on the functional properties of myocilin for aqueous humor (AH) outflow and to study in vivo the processing of mutated Tyr437His myocilin. Myocilin is a secreted glycoprotein that is mutated in some forms of primary open-angle glaucoma (POAG), and patients with the Tyr437His mutation have severe phenotypes. METHODS The chicken betaB1-crystallin promoter was used to overexpress wild-type human myocilin and mutated Tyr437His myocilin in the lenses of transgenic mice. Expression of transgenic mRNA was monitored by Northern blot analysis and in situ hybridization. The localization and secretion of transgenic myocilin was investigated by Western blot analysis and light and electron microscopy. Intraocular pressure (IOP) was measured by anterior chamber cannulation. RESULTS Two independent lines were established with each of the constructs that showed a strong expression of transgenic mRNA in their lenses. Transgenic expression resulted in a 4.7 +/- 1.8-fold increase of secreted normal myocilin in mouse AH, compared with its concentration in human AH. Immunoreactivity for transgenic myocilin was observed along the surfaces of lens and corneal endothelium, and in the chamber angle. At 12 weeks of age, the ultrastructure of the trabecular meshwork in mice expressing normal myocilin was not different from that of control eyes, and IOP of transgenic animals did not significantly differ from that of control littermates. In contrast, mutated Tyr437His myocilin was not secreted from lens fibers, but accumulated in dilated cisterns of rough endoplasmic reticulum. Although no structural changes were observed in lenses of animals expressing normal myocilin, lenses with Tyr437His expression developed nuclear cataracts, completely lost transparency, and eventually ruptured. Structural changes in lenses of Tyr437His expressing mice were correlated with a significant increase in IOP. CONCLUSIONS The results do not support the concept that increasing amounts of myocilin in the outflow tissues obstruct the system and directly cause an increase in outflow resistance. Mutated Tyr437His myocilin is not secreted in vivo and causes severe alterations of cellular structure and function. A comparable mechanism may cause POAG in patients with myocilin mutations.
Physical presence: palettes in virtual spaces

We have built a hand-held palette for touch-based interaction in virtual reality. this palette incorporates a high-resolution digitizing touch screen for input. It is see-through, and therefore does not occlude objects displayed behind it. These properties make it suitable for direct manipulation techniques in a range of virtual reality display systems. We implemented several interaction techniques based on this palette for an interactive scientific visualization task. These techniques, the tool's design, and its limitations are discussed in this paper.
A Stochastic Processes Toolkit for Risk Management

In risk management it is desirable to grasp the essential statistical features of a time series representing a risk factor. This tutorial aims to introduce a number of different stochastic processes that can help in grasping the essential features of risk factors describing different asset classes or behaviors. This paper does not aim at being exhaustive, but gives examples and a feeling for practically implementable models allowing for stylised features in the data. The reader may also use these models as building blocks to build more complex models, although for a number of risk management applications the models developed here suffice for the first step in the quantitative analysis. The broad qualitative features addressed here are {fat tails} and {mean reversion}. We give some orientation on the initial choice of a suitable stochastic process and then explain how the process parameters can be estimated based on historical data. Once the process has been calibrated, typically through maximum likelihood estimation, one may simulate the risk factor and build future scenarios for the risky portfolio. On the terminal simulated distribution of the portfolio one may then single out several risk measures, although here we focus on the stochastic processes estimation preceding the simulation of the risk factors Finally, this first survey report focuses on single time series. Correlation or more generally dependence across risk factors, leading to multivariate processes modeling, will be addressed in future work.
Danish Quality Database for Mammography Screening

Aim The Danish Quality Database for Mammography Screening (DKMS) was established in 2007, with the aim to monitor, sustain, and improve the quality of the Danish national breast cancer screening program. Study population All Danish women aged 50–69 years who were invited every 2 years for breast cancer screening in the nationwide program since July 10, 2007. Main variables The DKMS consists of data retrieved from the five regional invitation systems, the National Pathology Registry, and the National Registry of Patients. The DKMS covers the entire screening process and includes variables required to determine the following eleven indicators: 1) radiation exposure, 2) participation among invited women and participation within the target population, 3) time between screening and result, 4) screening interval, 5) recall for further diagnostics, 6) interval cancers consisting of women diagnosed with breast cancer between screening rounds, 7) invasive breast tumors, 8) node-negative cancers, 9) invasive tumors ≤10 mm, 10) ratio of surgery for benign vs malignant lesions, and 11) breast-conserving therapy. Descriptive data As of August 10, 2015, the database included data from 888,151 unique women who have been invited to one or more screenings. In the first three screening rounds, 641,835 (round I), 580,452 (round II), and 641,938 (round III) women were invited, and participation increased from 79% to 84%. In the third round, 79% of the screened women received their result within ten working days, 2.7% of the screened women were recalled for further diagnostics, 82% of the women operated for invasive carcinomas were node negative, and 40% of the women had the tumor size of ≤10 mm. Conclusion The DKMS has successfully evaluated the quality of the nationwide Danish breast cancer screening program against international quality standards. The quality of the Danish program complies well with international standards particularly as regards to the clinical aspects.
AGILE: adaptive indexing for context-aware information filters

Information filtering has become a key technology for modern information systems. The goal of an information filter is to route messages to the right recipients (possibly none) according to declarative rules called profiles. In order to deal with high volumes of messages, several index structures have been proposed in the past. The challenge addressed in this paper is to carry out stateful information filtering in which profiles refer to values in a database or to previous messages. The difficulty is that database update streams need to be processed in addition to messages. This paper presents AGILE, a way to extend existing index structures so that the indexes adapt to the message/update workload and show good performance in all situations. Performance experiments show that AGILE is overall the clear winner as compared to the best existing approaches. In extreme situations in which it is not the winner, the overheads are small.
The Difference Of Determinants Of Mobile Data Services' Adoption And Continuance - A Longitudinal Study

The diffusion of mobile data services (MDS) has been growing tremendously since 2007. Owing to the ubiquity and usability of multipurpose information appliances (MIA) such as smartphones, MDS have permeated every walk of life of many people. Using MIA allow users to access MDS anytime and anywhere to satisfy utilitarian, hedonic, and social needs. Hence, MDS can provide both instrumental (e.g., productivity) and inherent (e.g., entertainment) value. To date little research exists about the changes in adoption and usage behavior over time and the differences in the factors influencing people in the pre- or post-adoption stage. The present study addresses these gaps. To validate the research model the paper builds upon data collected from 1,342 students in 2008 which will be questioned again in the course of the present study. It is expected that the findings will help refining researchers’ understanding regarding the differences of determinants influencing users and non-users.

Marker-less Real-time Camera Registration for Mixed Reality

A real-time and robust algorithm for 3D camera registration in a Mixed Reality (MR) environment is described in this paper. The most used technique for camera pose (position and orientation with respect to a fixed or moving object) is based on fiducial marker tracking. This method guarantees good results in real-time with a single camera, but needs several high contrast printed markers on external world in order to make possible the calculation of camera parameters and positioning. Thus real 3D geometric data are grabbed only through already known markers. The aim of this research is a real-time monocular camera tracking and registration through automatic image features extraction from video streaming. The first implementation of the method, several examples and confrontation with non interactive algorithm for SFM (Structure From Motion) have demonstrated that this meets the real-time response and sufficient precision needed by a Mixed Reality environment.
Translating Negation: A Manual Error Analysis

Statistical Machine Translation has come a long way improving the translation quality of a range of different linguistic phenomena. With negation however, techniques proposed and implemented for improving translation performance on negation have simply followed from the developers’ beliefs about why performance is worse. These beliefs, however, have never been validated by an error analysis of the translation output. In contrast, the current paper shows that an informative empirical error analysis can be formulated in terms of (1) the set of semantic elements involved in the meaning of negation, and (2) a small set of string-based operations that can characterise errors in the translation of those elements. Results on a Chinese-to-English translation task confirm the robustness of our analysis cross-linguistically and the basic assumptions can inform an automated investigation into the causes of translation errors. Conclusions drawn from this analysis should guide future work on improving the translation of negative sentences.
Genetic and Physical Interactions between Tel2 and the Med15 Mediator Subunit in Saccharomyces cerevisiae

Background In budding yeast, the highly conserved Tel2 protein is part of several complexes and its main function is now believed to be in the biogenesis of phosphatidyl inositol 3-kinase related kinases. Principal Findings To uncover potentially novel functions of Tel2, we set out to isolate temperature-sensitive (ts) mutant alleles of TEL2 in order to perform genetic screenings. MED15/GAL11, a subunit of Mediator, a general regulator of transcription, was isolated as a suppressor of these mutants. The isolated tel2 mutants exhibited a short telomere phenotype that was partially rescued by MED15/GAL11 overexpression. The tel2-15mutant was markedly deficient in the transcription of EST2, coding for the catalytic subunit of telomerase, potentially explaining the short telomere phenotype of this mutant. In parallel, a two-hybrid screen identified an association between Tel2 and Rvb2, a highly conserved member of the AAA+ family of ATPases further found by in vivo co-immunoprecipitation to be tight and constitutive. Transiently overproduced Tel2 and Med15/Gal11 associated together, suggesting a potential role for Tel2 in transcription. Other Mediator subunits, as well as SUA7/TFIIB, also rescued the tel2-ts mutants. Significance Altogether, the present data suggest the existence of a novel role for Tel2, namely in transcription, possibly in cooperation with Rvb2 and involving the existence of physical interactions with the Med15/Gal11 Mediator subunit.
Optimization Methods to Plan the Charging of Electric Vehicle Fleets

This paper describes an approach to optimize electric vehicle battery charging behavior with the goal of minimizing charging costs, achieving satisfactory state-of-energy levels, and optimal power balancing. Two methods for charging schedule optimization are compared. The first formulation uses a linear approximation of the battery behavior, whereas the second uses a quadratic approximation. A non-linear and state-dependent battery model is used to evaluate the solutions of the two methods . Our results indicate that the linear approximation is sufficient when considering the electric vehicle charging plan optimization.
Symptoms and Etiological Attribution: A Cross-Sectional Study in Mexican Outpatients with Psychosis and Their Relatives

This cross-sectional study aimed at identifying the most common attributions of their mental disorder in a Mexican patients who have experienced psychosis and their relatives and exploring how having experienced or not characteristic psychotic symptoms and their present clinical status might affect their etiological attributions. Past and current symptom profiles of 66 patients were as assessed with the SCID-I (Structured Clinical Interview for DSM-IV Axis I Disorders) and the PANSS (Positive and Negative Syndrome Scale), respectively. The etiological attribution of psychosis of patients (n = 62) and the relatives (n = 65) was assessed with the Angermeyer and Klusmann scale comprising 30 items into five categories: biology, personality, family, society, and esoteric. Patients and relatives attribute psychosis mainly to social factors. Relatives' attributions were not influenced by clinical profile of patients, whereas in the case of patients it was only current clinical status that showed a difference, with those in nonremission scoring higher personality and family factors. Acknowledging patients' and relatives' beliefs about mental disorders at onset and later on is particularly important in psychosis, a mental condition with severe and/or persistent symptoms, in order to promote better involvement in treatment and in consequence efficacy and recovery.
A Thermostabilized, One-Step PCR Assay for Simultaneous Detection of Klebsiella pneumoniae and Haemophilus influenzae

Klebsiella pneumoniae and Haemophilus influenzae are two common pathogens associated with respiratory tract infections. The identification of these pathogens using conventional molecular diagnostic tests requires trained personnel, cold-chain transportation, and storage-dependance, which does not render them user-friendly. The aim of this study was to develop a thermostabilized, cold-chain-free, one-step multiplex PCR for simultaneous detection of K. pneumoniae and H. influenzae. The multiplex PCR assay was designed to amplify the php gene of K. pneumoniae (202 bp) and p6 gene of H. influenzae (582 bp). In addition, the specific primer to amplify glm gene of Helicobacter pylori (105 bp) was included as an internal amplification control. Subsequently, the designed primers and all PCR reagents were thermostabilized by lyophilization. The stability of the thermostabilized PCR was evaluated using the Q10 method. The sensitivity and specificity of performances for thermostabilized PCR were evaluated using 127 clinical isolates and were found to be 100% sensitive and specific. The thermostabilized PCR mix was found to be stable for 30 days and the Q10 accelerated stability was found to be 3.02 months. A cold-chain-free, PCR assay for easy, rapid, and simultaneous detection of K. pneumoniae and H. influenzae was successfully developed in this study.
Religious Perceptions and the Use of Technology: Profiling the Future Teachers of Religious Education

This study analyzes the profile of Greek university students who will be teaching courses related to religion when they become practitioners at primary school and high school level, in relation to their views on technology. For this purpose, four factors were examined: religious beliefs, use of technology, attitude towards technology, and their views regarding the use of technology for the dissemination of religious beliefs. The sample comprised of 570 students studying at Departments of Theology and Primary School Education at Greek universities. The data analysis revealed that participants, in general, are not highly religious. Both believers and non-believers seem to have a positive attitude towards technology, which they are willing to use in an educational context. Furthermore, they do not believe that religion and technology contradict each other. The implications of the findings are also discussed.
Development of PCR for screening of enteroaggregative Escherichia coli

In this study, we determined the sequence of the EcoRI-PstI fragment of the plasmid pCVD432, also termed the enteroaggregative Escherichia coli (EAggEC) probe. A primer pair complementary to this probe was designed for PCR amplification of a 630-bp region. Comparison of the analysis of the EAggEC probe sequence with those in database libraries revealed no significant similarity to any known bacterial gene. Pure cultures of E. coli cells, as well as mixed cultures from stool specimens, were investigated with the PCR assay, the EAggEC probe test, and the adherence test. Of 50 E. coli strains which demonstrated aggregative adherence to HEp-2 cells, 43 (86%) were positive with the EAggEC PCR. All 43 of these strains reacted with the EAggEC probe. Six EAggEC strains gave negative results by both molecular techniques. In contrast, only 4 of 418 (0.96%) strains representing other categories of diarrheagenic E. coli demonstrated a positive PCR result. The PCR was also successful in screening for the presence of EAggEC in enriched cultures grown from stool specimens. Compared with cell culture assays and colony hybridization, our findings revealed that the PCR assay was more rapid, simple, and highly sensitive and can therefore be recommended as a screening method for EAggEC in the clinical laboratory.
Teleimpedance control of a synergy-driven anthropomorphic hand

In this paper, a novel synergy driven teleimpedance controller for the Pisa-IIT SoftHand is presented. Towards the development of an efficient, robust, and low-cost hand prothesis, the Pisa-IIT SoftHand is built on the motor control principle of synergies, through which the immense complexity of the hand is simplified into distinct motor patterns. As the SoftHand grasps, it follows a synergistic path with built-in flexibility to allow grasping of objects of various shapes using only a single motor. In this work, the hand grasping motion is regulated with an impedance controller which incorporates the user's postural and stiffness synergy profiles in realtime. In addition, a disturbance observer is realized which estimates the grasping contact force. The estimated force is then fedback to the user via a vibration motor. Grasp robustness and transparency improvements were evaluated on two healthy subjects while grasping different objects. Implementation of the proposed teleimpedance controller led to the execution of stable grasps by controlling the grasping forces, via modulation of hand compliance. In addition, utilization of the vibrotactile feedback resulted in reduced physical load on the user. While these results need to be validated with amputees, they provide evidence that a low-cost, robust hand employing hardware-based synergies is a viable alternative to traditional myoelectric prostheses.
Dynamo generated field emergence through recurrent plasmoid ejections

Abstract Magnetic buoyancy is believed to drive the transport of magnetic flux tubes from the convection zone to the surface of the Sun. The magnetic fields form twisted loop-like structures in the solar atmosphere. In this paper we use helical forcing to produce a large-scale dynamo-generated magnetic field, which rises even without magnetic buoyancy. A two layer system is used as computational domain where the upper part represents the solar atmosphere. Here, the evolution of the magnetic field is solved with the stress–and–relax method. Below this region a magnetic field is produced by a helical forcing function in the momentum equation, which leads to dynamo action. We find twisted magnetic fields emerging frequently to the outer layer, forming arch-like structures. In addition, recurrent plasmoid ejections can be found by looking at space–time diagrams of the magnetic field. Recent simulations in spherical coordinates show similar results.
