Determinants of individuals’ self-disclosure and instant information sharing behavior in micro-blogging

Micro-blogging is a new social networking service (SNS) that can be viewed as an easily accessible, simplified blog. The simple and swift spread properties of micro-blogging make it different to the conventional SNS. However, little empirical results were provided in prior literature to elaborate individual’s behavior of micro-blogging use. Consequently, this study aims to explore the possible influence of individuals’ motivations on their self-disclosure and instant information sharing behavior as well as the extent of perceived social support in micro-blogging. Individuals who had experiences on Plurk usage were invited as subjects. The partial least squares (PLS) was utilized to examine the proposed model and hypotheses. Analytical results indicate that popularity and interpersonal needs significantly influence individual’s self-disclosure, while interpersonal and entertainment needs significantly influence individual’s instant information sharing behavior. Moreover, both individual’s self-disclosure and instant information sharing behavior have a positive relationship with the perceived extent of social support.
Comparative ultrastructure of coxal glands in unfed larvae of Leptotrombidium orientale (Schluger, 1948) (Trombiculidae) and Hydryphantes ruber (de Geer, 1778) (Hydryphantidae)

Coxal glands of unfed larvae Leptotrombidium orientale (Schluger, 1948) (Trombiculidae), a terrestrial mite parasitizing vertebrates, and Hydryphantes ruber (de Geer, 1778) (Hydryphantidae), a water mite parasitizing insects were studied using transmission electron microscopy. In both species, the coxal glands are represented by a paired tubular organ extending on the sides of the brain from the mouthparts to the frontal midgut wall and are formed of the cells arranged around the central lumen. As in other Parasitengona, the coxal glands are devoid of a proximal sacculus. The excretory duct, joining with ducts of the prosomal salivary glands constitutes the common podocephalic duct, opening into the subcheliceral space. The coxal glands of L. orientale are composed of a distal tubule with a basal labyrinth, an intermediate segment without labyrinth, and a proximal tubule bearing tight microvilli on the apical cell surface and coiled around the intermediate segment. The coxal glands of H. ruber mainly consist of the uniformly organized proximal tubule with apical microvilli of the cells lacking the basal labyrinth. This tubule shows several loops running backward and forward in a vertical plane on the side of the brain. In contrast to L. orientale, larvae of H. ruber reveal a terminal cuticular sac/bladder for accumulation of secreted fluids. Organization of the coxal glands depends on the ecological conditions of mites. Larvae of terrestrial L. orientale possess distal tubule functioning in re‐absorption of ions and water. Conversely, water mite larvae H. ruber need to evacuate of the water excess, so the filtrating proximal tubule is prominent.
Subacute cutaneous lupus erythematosus exacerbated or induced by chemotherapy.

BACKGROUND Subacute cutaneous lupus erythematosus (SCLE), characterized by nonscarring, photodistributed, annular or papulosquamous plaques, is occasionally induced by medication. It has been strongly associated with antihypertensive medications and terbinafine hydrochloride. OBSERVATION We describe 3 women with breast cancer who developed SCLE-like eruptions after being administered doxorubicin hydrochloride and cyclophosphamide. Biopsy specimens of all 3 patients demonstrated an interface dermatitis. Treatment consisted of topical and/or systemic corticosteroids, photoprotection, and switching the chemotherapeutic regimens. CONCLUSIONS Based on clinicopathologic correlation and timing of chemotherapy exposure, the patients were believed to have drug-induced SCLE. Although cutaneous eruption, pruritus, and photosensitivity are known adverse effects of doxorubicin, to our knowledge there has been only 1 previously reported case of doxorubicin-induced SCLE.
Early palliative care and metastatic non-small cell lung cancer

Patients with advanced cancer experience a significant burden of physical symptoms and psychological distress at the end of life, and many elect to receive aggressive cancer-directed therapy. The goal of palliative care is to relieve suffering and promote quality of life (QOL) for patients and families. Traditionally, both the public and medical community have conceptualized the need for patients to make a choice between pursuing curative therapy or receiving palliative care. However, practice guidelines from the World Health Organization and leadership from the oncology and palliative care communities advocate a different model of palliative care that is introduced from the point of diagnosis of life-threatening illness. Early palliative care has been shown to provide benefits in QOL, mood, and health care utilization. Additionally, preliminary research has suggested that in contrast to fears about palliative care hastening death, referral to palliative care earlier in the course of illness may have the potential to lengthen survival, particularly in patients with advanced nonsmall-cell lung cancer. This review summarizes the literature on potential survival benefits of palliative care and presents a model of how early integrated palliative care could potentially influence survival in patients with advanced cancer.
The nature and origin of Seyfert warm absorbers

We collate the results of recent high resolution X-ray spectroscopic observations of 23 AGN, and use the resulting information to try to provide answers to some of the main open questions about warm absorbers: where do they originate, what effect do they have on their host galaxies, and what is their importance within the energetics and dynamics of the AGN system as a whole? We find that the warm absorbers of nearby Seyferts and certain QSOs are most likely to originate in outflows from the dusty torus, and that the kinetic luminosity of these outflows accounts for well under 1% of the bolometric luminosities of the AGN. Our analysis supports, however, the view that the relativistic outflows recently observed in two PG quasars have their origin in accretion disc winds, although the energetic importance of these outflows is similar to that of the Seyfert warm absorbers. We find that the observed soft X-ray absorbing ionisation phases fill less than 10% of the available volume. Finally, we show that the amount of matter processed through an AGN outflow system, over the lifetime of the AGN, is probably large enough to have a significant influence on the evolution of the host galaxy and of the AGN itself.
Severity of focal microgyria and associated rapid auditory processing deficits

Data from rodent models of induced microgyria suggest that bilateral damage leads to more severe rapid auditory processing deficits than unilateral damage. It is unclear whether this reflects the degree, or bilateral/unilateral nature, of damage. The current study evaluates the effects of microgyric severity by assessing rats with single- vs double-pair bilateral focal microgyric lesions, using auditory discrimination and MGN measures. Behavioral data show a significant auditory processing deficit on rapid processing tasks for microgyric as compared to control subjects, and also reveal more severe deficits for double- than for single-pair bilateral microgyrics. Greater disruptions are also seen in the MGN of double-pair compared to single-pair bilateral microgyric subjects.
Estimating sufficient reductions of the predictors in abundant high-dimensional regressions

We study the asymptotic behavior of a class of methods for sufficient dimension reduction in high-dimension regressions, as the sample size and number of predictors grow in various alignments. It is demonstrated that these methods are consistent in a variety of settings, particularly in abundant regressions where most predictors contribute some information on the response, and oracle rates are possible. Simulation results are presented to support the theoretical conclusion.
Cumulative attendance, assessment and cancer detection rate over four screening rounds in five English breast-screening programmes: a retrospective study.

BACKGROUND Data collection in the National Health Service Breast Screening Programme monitors performance in a different cohort of women each year. METHODS This paper follows a single cohort study of 57,425 women (aged 50-53, when first invited) over four screening rounds to find: how many women attend screening and how often; how many were assessed; how many times they were assessed; and the number of cancers detected at each round. RESULTS Average attendance in each round was 76.9% and has remained constant. Only 62% of women have attended all four rounds, but 89.9% have been screened at least once, the average number of attendances being 3.5. Average assessment rate decreased from 7.3 to 3.5%. A total of 11.3% of women were assessed once, 0.91% twice and 0.06% three times. Cancer detection rates have more than doubled from 3.3 per 1000 screened to 6.9. CONCLUSIONS Current monitoring shows constant uptake over time, but when looking at a cohort of individual woman, a much larger percentage have 'ever' attended and a smaller number have attended all invitations. The chance of a woman being assessed at all, if she attends all four rounds, is 12.3%, which can be calculated by summating the recall rates in each round.
Beware of What You Share: Inferring Home Location in Social Networks

In recent years, social media users are voluntarily making large volume of personal data available on the social networks. Such data (e.g., professional associations) can create opportunities for users to strengthen their social and professional ties. However, the same data can also be used against the user for viral marketing and other unsolicited purposes. The invasion of privacy occurs due to privacy unawareness and carelessness of making information publicly available. In this paper, we perform a large-scale inference study in three of the currently most popular social networks: Foursquare, Google+ and Twitter. Our work focuses on inferring a user's home location, which may be a private attribute, for many users. We analyze whether a simple method can be used to infer the user home location using publicly available attributes and also the geographic information associated with locatable friends. We find that it is possible to infer the user home city with a high accuracy, around 67%, 72% and 82% of the cases in Foursquare, Google+ and Twitter, respectively. We also apply a finer-grained inference that reveals the geographic coordinates of the residence of a selected group of users in our datasets, achieving approximately up to 60% of accuracy within a radius of six kilometers.
“I Object!” Modeling Latent Pragmatic Effects in Courtroom Dialogues

Understanding the actionable outcomes of a dialogue requires effectively modeling situational roles of dialogue participants, the structure of the dialogue and the relevance of each utterance to an eventual action. We develop a latent-variable model that can capture these notions and apply it in the context of courtroom dialogues, in which the objection speech act is used as binary supervision to drive the learning process. We demonstrate quantitatively and qualitatively that our model is able to uncover natural discourse structure from this distant supervision.
Chlamydia trachomatis Inclusions Induce Asymmetric Cleavage Furrow Formation and Ingression Failure in Host Cells

ABSTRACT Chlamydia trachomatis infection has been suggested to induce host genome duplication and is linked to increased risks of cervical cancer. We describe here the mechanism by which Chlamydia causes a cleavage furrow defect that consistently results in the formation of multinucleated host cells, a phenomenon linked to tumorigenesis. Host signaling proteins essential for cleavage furrow initiation, ingression, and stabilization are displaced from one of the prospective furrowing cortices after Chlamydia infection. This protein displacement leads to the formation of a unique asymmetrical, unilateral cleavage furrow in infected human cells. The asymmetrical distribution of signaling proteins is caused by the physical presence of the Chlamydia inclusion at the cell equator. By using ingested latex beads, we demonstrate that the presence of a large vacuole at the cell equator is sufficient to cause furrow ingression failure and can lead to multinucleation. Interestingly, internalized latex beads of similar size do not localize to the cell equator as efficiently as Chlamydia inclusions; moreover, inhibition of bacterial protein synthesis with antibiotic reduces the frequency at which Chlamydia localizes to the cell equator. Together, these results suggest that Chlamydia effectors are involved in strategic positioning of the inclusion during cell division.
Design and Development of Digital Ramptime Current Control Technique

A new all-digital current control technique, called Digital Ramptime current control, is presented in this paper. The control technique, based on Ramptime current control technique, uses multisampling as the sampling strategy that results in a high accuracy of control. In an active power filter experiment, compared with the original Ramptime current control, the performance of the Digital Ramptime current control is found to be satisfactory.
The accuracy of numerical conformal mapping methods: a survey of examples and results

This paper shows how the geometry of the region affects the conditioning and the accuracy of numerical conformal mapping methods for simply connected regions, especially Fourier series methods. Both explicit examples of popular test cases and more general estimates are discussed. The severe ill conditioning that is known as the crowding phenomenon is discussed and its effect on a conformally transplanted boundary value problem is illustrated. Remarks on various numerical methods are included.

Improved speech-to-text translation with the Fisher and Callhome Spanish-English speech translation corpus

Research into the translation of the output of automatic speech recognition (ASR) systems is hindered by the dearth of datasets developed for that explicit purpose. For Spanish-English translation, in particular, most parallel data available exists only in vastly different domains and registers. In order to support research on cross-lingual speech applications, we introduce the Fisher and Callhome Spanish-English Speech Translation Corpus, supplementing existing LDC audio and transcripts with (a) ASR 1-best, lattice, and oracle output produced by the Kaldi recognition system and (b) English translations obtained on Amazon’s Mechanical Turk. The result is a four-way parallel dataset of Spanish audio, transcriptions, ASR lattices, and English translations of approximately 38 hours of speech, with defined training, development, and held-out test sets. We conduct baseline machine translation experiments us-ing models trained on the provided training data, and validate the dataset by corroborating a number of known results in the field, including the utility of in-domain (information, conversational) training data, increased performance translating lat-tices (instead of recognizer 1-best output), and the relationship between word error rate and BLEU score.
An Approach to Distributed Video Coding Using 3D Face Models

Distributed source coding (DSC), formulated thirty years ago, is lately witnessing a great research effort. This effort is encouraged by emerging new applications that could greatly benefit from the properties inherent to DSC, like low complexity encoders and embedded error resilience. Among the challenging topics related to DSC there is the generation of the side information, an estimation made by the decoder of the information being decoded. This paper quickly summarizes the theoretical bases of DSC and then focuses on the essential task of generating the side information, by developing the model-based method drafted by the authors on a previous publication. It is shown that the application of model-based side information generation techniques on top of current state of the art DSC-based video codecs provides an improvement of 0.5 to 0.75 dB over a wide range of bit-rates. Comparisons against H.264 are also provided.
Peer victimization, cyberbullying, and suicide risk in children and adolescents.

Aggressive behavior involving a power imbalance, bullying is inflicted on an adolescent by another adolescent, or even by a group of youths, and it is highly likely to be repeated again and again. Bullying can cause physical, psychological, social, or educational harm.1 It can take the form of physical assaults, verbal harassment, and threatening behaviors, or it could involve psychological and social strategies (eg, exclusion, rumor spreading). Similarly, cyberbullying is defined as victimization perpetrated through information technologies (ie, cell phones, Internet). Prevalence figures of bullying appear to vary somewhat across countries. Large-scale cross-nationalstudieshaveestimatedthat 10%to20%ofyouthhave beenbulliedbypeersduringtheir schoolyears,while5%to15%have bullied others.2 Moreover, many children who are bullied experience repeated and sustained victimization across time. Bullying is no longer seen as conflictual interactions that help youth become tougher, and it no longer is viewed as inevitable or beneficial. In contrast, pediatric, psychiatric, and psychological research has documented—both concurrently and longitudinally— adverse consequences of being bullied at school and online in children’s and adolescents’ lives, including psychological problems (eg, depression, anxiety, low self-esteem)3 and physical health symptoms.4 Being repeatedly bullied by peers is also a risk factor for extremeconsequences, including suicide. In a recent JAMAPediatrics meta-analysis, vanGeel andcolleagues5 conducteda systematic literature review on the relation between peer victimization and suicide ideation and attempts. In the article, suicide ideation, which is usually seen as a precursor to suicide, was defined as thoughts or wishes to end one’s life, whereas suicide attemptswere referred to as nonfatal suicide attempts. Themeta-analysis included 34 cross-sectional studies that reported associations between peer victimization and suicide ideation among 284 375 participants aged 9 to 21 years. Results indicated that bullying victimization was significantly associated with suicide ideation (random-effectsmodel: odds ratio [OR], 2.23;95% CI, 2.10-2.37). This associationwas not affected by publication bias JAMAPEDIATRICS
The efficacy of error mitigation techniques for DRAM retention failures: a comparative experimental study

As DRAM cells continue to shrink, they become more susceptible to retention failures. DRAM cells that permanently exhibit short retention times are fairly easy to identify and repair through the use of memory tests and row and column redundancy. However, the retention time of many cells may vary over time due to a property called Variable Retention Time (VRT). Since these cells intermittently transition between failing and non-failing states, they are particularly difficult to identify through memory tests alone. In addition, the high temperature packaging process may aggravate this problem as the susceptibility of cells to VRT increases after the assembly of DRAM chips. A promising alternative to manufacture-time testing is to detect and mitigate retention failures after the system has become operational. Such a system would require mechanisms to detect and mitigate retention failures in the field, but would be responsive to retention failures introduced after system assembly and could dramatically reduce the cost of testing, enabling much longer tests than are practical with manufacturer testing equipment. In this paper, we analyze the efficacy of three common error mitigation techniques (memory tests, guardbands, and error correcting codes (ECC)) in real DRAM chips exhibiting both intermittent and permanent retention failures. Our analysis allows us to quantify the efficacy of recent system-level error mitigation mechanisms that build upon these techniques. We revisit prior works in the context of the experimental data we present, showing that our measured results significantly impact these works' conclusions. We find that mitigation techniques that rely on run-time testing alone [38, 27, 50, 26] are unable to ensure reliable operation even after many months of testing. Techniques that incorporate ECC[4, 52], however, can ensure reliable DRAM operation after only a few hours of testing. For example, VS-ECC[4], which couples testing with variable strength codes to allocate the strongest codes to the most error-prone memory regions, can ensure reliable operation for 10 years after only 19 minutes of testing. We conclude that the viability of these mitigation techniques depend on efficient online profiling of DRAM performed without disrupting system operation.
Amygdala Sensitivity to Race Is Not Present in Childhood but Emerges over Adolescence

Neuroimaging research in adults has consistently found that differential perception of race is associated with increased amygdala activity. We hypothesized that such neural biases unlikely reflect innate processes but instead emerge over development. In the current study, we used fMRI to examine the neurodevelopmental trajectory of the amygdala in response to race across childhood and adolescence ranging from 4 to 16 years. Thirty-two youths viewed African American and European American faces during a functional brain scan. Results suggest that differential amygdala response to African American faces does not emerge until adolescence, reflecting the increasing salience of race across development. In addition, greater peer diversity was associated with attenuated amygdala response to African American faces, suggesting that intergroup racial contact may reduce the salience of race.
Severity signs of childhood diarrhoea in north eastern Nigeria

Oral Rehydration Therapy (ORT) use in Nigeria is currently far short of the na tional Control of Diarrhoeal Diseases (CDD) programme goals. Towards designing health education strategies to improve this, maternal lay health concerns during diarrhoea in under-fives were examined among two large ethnic groups, the Kanuris and Buras, in north- eastern Nigeria. Over half of the respondents judged the severity of diarrhoea by more than one sign and expected ORT to stop diarrhoea. Severity signs frequently described (averaging from a quarter to a half of respondents) included weakness and refusal of food; frequent stooling and fever were more frequently used by the Kanuris (p < 0.001) compared to Buras and weight loss and dehydration by the Buras (p < 0.01) compared to Kanuris. Generally, rural residents were less concerned with dehydration and weight loss (p < 0.0001 and 0.003 respectively, compared to urban residents) and more concerned with restlessness, including excessive crying (p < 0.07 to 0.0001). Stool characteristics and vomiting were rarely used as severity signs although the Kanuris in focus group discussions related severity to diarrhoea typology. Concerns with persistent diarrhoea, and diarrhoea associated with measles, were rarely expressed by participants, irrespective of ethnic group and domicile, suggesting that health education aimed at increasing awareness in relation to these two serious illnesses is urgently needed in Nigeria. Several of the lay health concerns expressed by participants in the study could form a useful basis for promoting ORT use in Nigeria and elsewhere.
