Exploring Types of Parent–Child Relationship and Internet use across Europe

This article explores internet-related parent–child relationships across twenty-five European countries. Parent–child dyads are analysed in terms of parental mediation, digital competence, and communicative proximity, in order to answer the following research questions: Which types of parent–child relationship with respect to internet use can be found? How do they coincide with developmental, social, and cultural patterns? And how are they distributed across European Union countries? Using data from the EU Kids Online survey, four types of parent–child relationship were identified. The types are shaped by several factors on the level of child, family, and country, with the child's age and internet use being the most important predictors. Based on the prevalence of these family types, six country clusters were identified, which represent technical, social, and cultural contexts shaping the type of internet-related parent–child relationship.
Quinone Profiles of Thermoplasma acidophilum HO-62

ABSTRACT Quinones of Thermoplasma acidophilum HO-62 were analyzed by high-performance liquid chromatography, mass spectrometry, and nuclear magnetic resonance. Menaquinone, methionaquinone, and 2-trans and 2-cis forms of thermoplasmaquinone were identified. The relative amount of thermoplasmaquinone increased under anaerobic conditions, and those of menaquinone and methionaquinone increased under aerobic conditions.
Collective life: parents, playground encounters and the multicultural city

For parents, the school playground is a site of daily intermingling—an important and yet often overlooked site of sociality. Yet whilst it is a space where common needs and experiences are shared, and where friendships and subtle gestures of familiarity are formed, it is also a site of ‘panoptic force’, where on-going conflicts over class, religion, race and competing interpretations of morality are played out and reinforced. This paper focuses on an ethnographic account of an urban multicultural primary school in Birmingham, UK, to argue that the playground, as a prosaic space of urban encounter, can open up a new set of discussions around segregation and the everyday (dis)assemblies of collective life. Attending to both the routines of daily school life and the work of a voluntary Parents Group that aims to address the challenges of living with difference, the paper details the fragile associations, friendships and mechanisms for social learning that develop within the prosaic spaces of the playground. As such, the paper (re)positions the playground as a site of productive sociality, ongoing negotiation and incremental change, which can work to counter anxieties around cultural diversity and challenge wider concerns about the state of contemporary multiculturalism.
FPGA based all-on-chip DSTATCOM control for power quality improvement

In this paper, FPGA based all-on-chip digital controller is proposed which includes PI controller, +sequence detector, instantaneous power calculator, low-pass filters and hysteresis current controller. All these modules are configured on FPGA hardware resources aimed to mitigate harmonics and compensate reactive power in power distribution network. VHDL code for each module has been generated with help of System Generator. The whole controller is implemented on vertex-5 xc5vlx110t chip of Xilinx and tested with ML-509 co-simulation platform with low power laboratory DSTATCOM prototype. After verification it has been found that all-on-chip digital controller is able to compensate balanced/unbalanced non-linear load with distorted PCC voltage within allowable range of IEEE standard 519.
Pose-based SLAM with probabilistic scan matching algorithm using a mechanical scanned imaging sonar

This paper proposes a pose-based algorithm to solve the full SLAM problem for an Autonomous Underwater Vehicle (AUV), navigating in an unknown and possibly unstructured environment. The technique incorporate probabilistic scan matching with range scans gathered from a Mechanical Scanning Imaging Sonar (MSIS) and the robot dead-reckoning displacements estimated from a Doppler Velocity Log (DVL) and a Motion Reference Unit (MRU). The proposed method utilizes two Extended Kalman Filters (EKF). The first, estimates the local path travelled by the robot while grabbing the scan as well as its uncertainty and provides position estimates for correcting the distortions that the vehicle motion produces in the acoustic images. The second is an augment state EKF that estimates and keeps the registered scans poses. The raw data from the sensors are processed and fused in-line. No priory structural information or initial pose are considered. The algorithm has been tested on an AUV guided along a 600m path within a marina environment, showing the viability of the proposed approach.
Explaining Language Priming Effects

The present study examined participants' responses to scales measuring cultural identifications and self-esteem among both Hong Kong Chinese and Mainland Chinese bilinguals. When the authors activated their ethnolinguistic identity and manipulated the language of assessment, Chinese-English bilinguals were found to identify more with Chinese culture but less with Western culture, and to report lower self-esteem when responding in English than in Chinese. These results were interpreted as arising from activation of the participants' ethnolinguistic identity and their becoming aware of their own ethnic vitality and cultural norms, leading to ethnic affirmation (contrast effect) rather than cultural accommodation (assimilation effect).
Finding DNA motifs: A probabilistic suffix tree approach

We address the problem of de novo motif identification. That is, given a set of DNA sequences we try to identify motifs in the dataset without having any prior knowledge about existence of any motifs in the dataset. We propose a method based on Probabilistic Suffix Trees (PSTs) to identify fixed-length motifs from a given set of DNA sequences. Our experiments reveal that our approach successfully discovers true motifs. We compared our method with the popular MEME algorithm, and observed that it detects a larger number of correct and statistically significant motifs than MEME. Our method is highly efficient as compared to MEME in finding the motifs when processing datasets of 1000 or more sequences. We applied our method to sequences of mutant strains of Exophiala dermatitidis and successfully identified motifs which revealed several transcription factor binding sites. This information is important to biologists for performing experiments to understand their role in different regulatory pathways affected by cdc42. We also show that our PST approach to de novo motif discovery can be used successfully to identify motifs in ChIP-Seq datasets. These motifs in turn identify binding sites for proteins in the sequences. iii ACKNOWLEDGMENTS My heart felt gratitude goes to my advisors, Prof. encouragement it would not have been possible for me to complete the dissertation. I would also like to thank Prof. Steven Harris, for his continued support, insight and help. His expertise has been a guiding star in the development of this dissertation.
Artistic Surface Rendering Using Layout of Text

An artistic rendering method of free‐form surfaces with the aid of half‐toned text that is laid‐out on the given surface is presented. The layout of the text is computed using symbolic composition of the free‐form parametric surface S(u, v) with cubic or linear Bézier curve segments C(t) = {cu (t), cv (t)}, comprising the outline of the text symbols. Once the layout is constructed on the surface, a shading process is applied to the text, affecting the width of the symbols as well as their color, according to some shader function. The shader function depends on the surface orientation and the view direction as well as the color and the direction or position of the light source.
Modeling and understanding end-to-end class of service policies in operational networks

Business and economic considerations are driving the extensive use of service differentiation in Virtual Private Networks (VPNs) operated for business enterprises today. The resulting Class of Service (CoS) designs embed complex policy decisions based on the described priorities of various applications, extent of bandwidth availability, and cost considerations. These inherently complex high-level policies are realized through low-level router configurations. The configuration process is tedious and error-prone given the highly intertwined nature of CoS configuration, the multiple router configurations over which the policies are instantiated, and the complex access control lists (ACLs) involved. Our contributions include (i) a formal approach to modeling CoS policies from router configuration files in a precise manner; (ii) a practical and computationally efficient tool that can determine the CoS treatment received by an arbitrary set of flows across multiple routers; and (iii) a validation of our approach in enabling applications such as troubleshooting, auditing, and visualization of network-wide CoS design, using router configuration data from a cross-section of 150 diverse enterprise VPNs. To our knowledge, this is the first effort aimed at modeling and analyzing CoS configurations.
Corest: A Measure of Color and Space Stability to Detect Salient Regions According to Human Criteria

In this paper we present a novel method to obtain regions of interest in color images. The strategy consists in the evaluation of the stability of a region according to its properties of color and spatial arrangement. We propose a fusion of the classical color image segmentation with the space scale analysis. An image can be decomposed in a set of regions that describe the whole image content. Using a set of manual labelled images we have evaluated the properties of the detector according to the human perception. The proposed region detector has a potential application in the field of the content based image retrieval by sketch.
Attention deficits in children with <750 gm birth weight.

Although attention deficit disorders are frequently diagnosed in low birth-weight children, it is not clear if attention problems are apparent in neuropsychological testing. The present study examined the performances of a regional sample of 68 children with birth weights <750 gm on several psychometric measures of attention given at early school age. Matched groups of 65 children with birth weights between 750–1499 gm and 61 term controls were also assessed. The group <750 gm performed more poorly on one attention test than did either comparison group, even when overall cognitive ability was taken into account. Performances on the attention tests were also related to academic skills and ratings of behavior. Findings confirm the hypothesis that children with birth weights <750 gm have specific attentional weaknesses and support the validity of attention tests as predictors of learning and behavior problems.
Long-term results of cytoreductive surgery for advanced and recurrent epithelial ovarian cancers and papillary serous carcinoma of the peritoneum

The aim of this study was to review the long-term results of cytoreductive surgery in the treatment of advanced primary and recurrent epithelial ovarian cancers and papillary serous carcinoma of the peritoneum. Our goal was to identify clinical factors by which to select patients likely to benefit from a comprehensive management plan. Clinical data of 28 females who underwent surgery were retrieved from a prospective database. Major cytoreductive procedures were possible in 25 patients. Heated intraoperative or early postoperative intraperitoneal chemotherapy was also used where appropriate. The median follow-up after cytoreduction was 26.9 months. The overall median survival after cytoreduction was 45.8 months. The prognostic indicators associated with a statistically significant impact on survival were the Prior Surgery Score (P < 0.001), the Completeness of Cytoreduction Score (P = 0.037) and response to chemotherapy prior to surgery (P = 0.012). Our findings suggest that cytoreductive surgery can be effective when combined with perioperative intraperitoneal chemotherapy. Results can be improved by excluding cases where completeness of cytoreduction seems unlikely. Extensive prior surgery without the protection of adjunctive intraperitoneal chemotherapy is associated with a poor prognosis. This may be due to disruption of anatomic planes leading to deep abdominal and pelvic dissemination intractable to further treatment.
Comparative study of telecommunication methods for emergency telemedicine

Sir, When a medical emergency occurs, the most important determinant of the mortality rate is the time taken for the patient to receive appropriate treatment1. If there is no one in the vicinity, there is likely to be a dangerous delay. A wearable device that continuously monitors the physical state of the user, in particular vital signs such as pulse rate, could assist with this problem if it had the ability to communicate with medical emergency centres2. A number of telecommunication methods are now available for this purpose, including radio frequency (RF) transmission, the short message service (SMS) on a mobile phone and Bluetooth transmission3. We have compared the characteristics of these three wireless telecommunication methods from the standpoint of emergency telemedicine.
HYL1 controls the miR156-mediated juvenile phase of vegetative growth

HYL1 is an important regulator of microRNA (miRNA) biogenesis. A loss-of-function mutation of HYL1 causes the reduced accumulation of some miRNAs but fails to display the miRNA-deficient phenotypes of these miRNAs. In Arabidopsis, miR156 mediates phase transition through repression of SQUAMOSA PROMOTER-BINDING PROTEIN-LIKE (SPL) genes. However, it remains unknown whether, and if so how, HYL1 enables phase transition through miR156. This study showed that a loss-of-function mutation of the HYL1 gene caused defects in the timing of the juvenile phase. In the primary leaves of hyl1-2 mutants, abaxial trichomes were generated prematurely, the leaf blades elongated, and the blade base angles enlarged, as is observed for adult leaves. In hyl1-2 p35S::miR156a and hyl1-2 spl9-4 spl15-1 plants, increased accumulation of miR156a and repressed expression of the SPL genes were concomitant with a complete or partial rescue of the hyl1-2 phenotype in phase defects. In contrast, overexpression of the SPL9 gene in hyl1-2 mutants led to total disappearance of the juvenile phase. Moreover, HYL1 prevented the premature accumulation of adult-related transcripts in the primary leaves. Taken together, these results suggest that HYL1 controls the expression levels of miR156-targeted SPL genes and enables plants to undergo the juvenile phase, an important and critical step during plant development to ensure maximum growth and productivity.
Extracting Patterns from Brazilian Guitar Accompaniment Data

The analysis of expressive performance, an important research topic in Computer Music, is almost exclusively devoted to the study of western classical piano music. Instruments like the acoustic guitar and styles like Bossa Nova and Samba have almost never been studied, despite their harmonic and rhythmic richness. This paper describes some experimental results obtained with the extraction of rhythmic patterns from the guitar accompaniment of Bossa Nova songs. It also discuss the relevance of such experiments, as well as the importance of the computer techniques used in them, to the music and musical culture in general.
The influence of social relations on mortality in later life: a study on elderly Danish twins.

PURPOSE We examined whether the presence of a spouse and the frequency of interaction with children, relatives, and friends significantly influence the risk of dying in late life. We assessed these effects separately by gender, controlling for self-reported health. In addition, we examined whether interaction with the co-twin has a different impact on mortality for identical and fraternal twins. DESIGN AND METHODS The data set consists of 2,147 Danish twins aged 75 years and older, who were followed prospectively from 1995 to 2001. We modeled the effect of social ties on mortality by using event history analysis. RESULTS Survival is extended by having a spouse and close ties with friends and the co-twin. However, contact frequency with friends and the co-twin is significant, respectively, only for women and identical twins. IMPLICATIONS Investigating social relations sheds light on the life span of individuals older than 75 years of age. We stress the importance of social relations beyond the presence of the spouse for survival even at very old ages.
Coil combination of multichannel MRSI data at 7 T: MUSICAL

The goal of this study was to evaluate a new method of combining multi‐channel 1H MRSI data by direct use of a matching imaging scan as a reference, rather than computing sensitivity maps. Seven healthy volunteers were measured on a 7‐T MR scanner using a head coil with a 32‐channel array coil for receive‐only and a volume coil for receive/transmit. The accuracy of prediction of the phase of the 1H MRSI data with a fast imaging pre‐scan was investigated with the volume coil. The array coil 1H MRSI data were combined using matching imaging data as coil combination weights. The signal‐to‐noise ratio (SNR), spectral quality, metabolic map quality and Cramér–Rao lower bounds were then compared with the data obtained by two standard methods, i.e. using sensitivity maps and the first free induction decay (FID) data point. Additional noise decorrelation was performed to further optimize the SNR gain. The new combination method improved significantly the SNR (+29%), overall spectral quality and visual appearance of metabolic maps, and lowered the Cramér–Rao lower bounds (−34%), compared with the combination method based on the first FID data point. The results were similar to those obtained by the combination method using sensitivity maps, but the new method increased the SNR slightly (+1.7%), decreased the algorithm complexity, required no reference coil and pre‐phased all spectra correctly prior to spectral processing. Noise decorrelation further increased the SNR by 13%. The proposed method is a fast, robust and simple way to improve the coil combination in 1H MRSI of the human brain at 7 T, and could be extended to other 1H MRSI techniques. © 2013 The Authors.

Catalog Use in a Large Research Library

Concern with the questions of when and how best to computerize the catalog of a large research library, and how to improve an existing conventional catalog, motivated a study of the utilization of the main catalog of the Yale University Library. The study was carefully designed to provide a representative sample of catalog use. Traffic through the catalog area was observed over a period of more than a year. A schedule of interviews with catalog users was based on observed traffic volume by hour of day, day of week, and time of year. More than 2,000 interviews were completed, using nonleading interviewing technique. Information was derived on the catalog user's objective, starting clues, and university affiliation. Search success was determined. Follow-up studies were performed on the catalog cards and the actual books identified in successful searches. Reasons for search failure were determined for known-item searches. Availability and accuracy of different categories of search clues were ascertained. Published algorithms for searching computerized bibliographic files were evaluated. Attention was given to the feasibility of automatic construction of computerized catalogs. Some of the available results are presented and discussed.
A semi-blind watermarking algorithm for color images using chaotic maps

In this paper a semi-blind watermarking method for color images is introduced based on chaotic maps. To achieve a secure design, the method generates a pseudo-random binary watermark by a chaotic map and embeds the watermark bits in Red, Green, and Blue pixels of the color image. In the detection stage, the watermark bits are extracted without requirement to the original image, of course the embedding positions' addresses are needed. The simulation results show that the proposed method has good performance in terms of the peak signal to noise ratio and the bit error rate quality measures.
VISION BASED RESPIRATORY MONITORING SYSTEM

Breathing monitoring systems are demonstrating to have an increasing interest since they can aid to diagnose the patient breathing deficiencies as well as other pathologies and thus to decide the adequate therapy. This paper describes one such system based on vision, that measures the evolution of the breathing through the analysis of the patient's movement. This remote sensor, besides being completely safe, makes possible a continuous supervision of the patient without causing any disturbance or imposing constraints in the patient actions an behaviour during the monitoring period.
Gameplay Habits among Middle School Students: A Descriptive Study

Computer games as new media culture have become increasing popular among young people. Today most children play a different genre of games at different times depending on their age, maturity, and opportunity. While some researchers advocate that similar to computer literacy and information literacy, game literacy will be one of the requirements for future generation of students, others raised concerns that excessive gameplaying can lead to aggressive behavior and isolation. A pilot study was conducted in a boy's school in the United Arab Emirates to find out gameplaying habits among 234 middle school students, age ranging from 11 to 19 years old. The results suggested that the students are not playing extreme games and they are playing games during the holidays. Further study is suggested to explore in other schools including the gameplay habits among the girls.
Atypical Tzanck smear findings in pemphigus vulgaris

tiocytomas, osteosarcomas and fibrosarcomas have been reported arising in a benign GCTB. While malignant transformation in a GCTB is rare, metastasis from the malignant component is even more rarely documented. Fine needle aspiration cytology smears from benign GCTBs show mononuclear cells and osteoclastic giant cells. Criteria for malignancy include highly pleomorphic cells with bizarre nuclei, and atypical mitoses, along with osteoclastic giant cells, as noted in the present case. Areas of sarcomatous transformation were initially ‘missed’ in the tumour resection specimen. FNAC was useful in identifying sarcomatous deposits in the metastatic lymph node. Morphologically, the differential diagnoses included a poorly differentiated carcinoma and melanoma. While melanomas exhibit prominent nucleolisation with intranuclear inclusions, with or without melanin pigment, poorly differentiated carcinomas reveal overlapping or cohesive clusters. Certain poorly differentiated carcinomas contain osteoclastic giant cells. The clinical history was most important in this case for ruling out these differentials. Lymph node metastasis from this sarcomatous component denotes a grim prognosis. Whereas surgery is the traditional primary modality of treatment for GCTB of the bone, cases with sarcomatous transformation are treated similarly to a high-grade osteosarcoma with adjuvant chemotherapy, as was planned for this patient who further defaulted. To summarise, this report underpins the significant role of FNAC in the identification of sarcomatous deposits at metastatic sites in a rare case of a GCTB undergoing a sarcomatous transformation. The value of extensive histopathological tissue sampling and the careful assessment in cases of recurrent GCTBs occurring in older individuals cannot be overemphasised. The correct identification has significant therapeutic and prognostic implications.
