Induction and properties of cytoplasmic factor(s) which enhance nuclear nonhistone protein phosphorylation in lymphocytes stimulated by anti-Ig

An increased in vitro phosphorylation of nonhistone nuclear proteins (NHP) was observed in the nuclei isolated from rabbit lymphocytes which had been stimulated with anti-Ig for 4 h. No concomitant increase of phosphorylation in histones or 0.14 M NaCl-soluble proteins was observed. The increase of in vitro phosphorylation of NHP was also observed in the nuclei isolated from nonstimulated cells when these nuclei were preincubated for 2 h with cell-free extracts from anti-Ig- stimulated cells. The active substance in cell-free extracts was maximally induced when lymphocytes were stimulated with anti-Ig for 2 h. The induction of an increased phosphorylation of NHP in nonstimulated nuclei with the cell-free extracts was not due to decrease of the adenosine triphosphate pool in the extracts from anti- Ig-stimulated cells. The active substance in cell-free extracts was not NHP-protein kinase itself, but it probably activated NHP-protein kinase in quiescent nuclei. The active substance was nondialyzable and probably protein. It was resistant against heating at 56 degrees C for 30 min, but the activity was completely destroyed by heating at 90 degrees C for 30 min. The active substance may be responsible for the transduction of the membrane-mediated signals given through Ig receptors to nuclei.
Motivating the U.S. Voter: The Functions of Elaboration and Political Motives When Using TV and the Internet

This study tests the assumptions underlying a model that would combine elements of uses and gratifications and the elaboration likelihood model. The assumptions are as follows: (a) Media goals are more adequately fulfilled by using multiple channels, (b) there is a relationship between ritualized and instrumental media use orientations, and central and peripheral route message processing, (c) those who process information via the central route are likely to use both television and the Internet to seek political information, and (d) those who use political media message instrumentally and process them through the central route are likely to participate in political activities. The results showed that those who used both television and the Internet for political needs were more gratified than those who used only one of these channels. For television viewers, age, education, political content affinity, and receiver involvement predicted greater political activity. For Internet users, age, education, social interaction motivation, receiver involvement, and need for cognition predicted greater political activity. These results were discussed in relation to demonstrating connections between the uses and gratifications perspective and the elaboration likelihood model.
Dynamic Scene Understanding for Mobile Robot Navigation

This paper briefly summarizes some recent advances in monocular camera based visual navigation of mobile robots. The first part of this paper describes a self-supervised learning algorithm, which estimates vanishing point of the road and adaptively train color classifiers to detect the road and non-road areas. The second part deals with spatio-temporal consistency for 2D semantic scene analysis, addressed by learning visual similarities between pixels across frames and a simple filtering algorithm in online/causal manner.
Literary hypertext in the foreign language classroom: a case study report

Abstract Literary hypertext has often been acknowledged as the embodiment of poststructuralist literary theory (e.g. Coover, 1992; Landow, 1997; Bolter, 2001). The only literary medium that is produced, edited, published and received electronically, it encourages readings that defy the conventionally linear decoding process. With respect to text production, it opens up alternative ways of organising semantic structures in individualised, associative ways, which invites constructivist teaching approaches in the foreign language classroom. This article provides a general introduction to definitions, formal criteria, major theories and historical developments. It portrays a selection of existing structural and cognitive linguistic approaches, such as textuality, coherence, communication and learning psychology. A variety of teaching approaches are outlined to convey to what extent hypertext has entered the primary and secondary school syllabus. At the heart of this investigation lies a case study report describing one possible method of implementing literary hypertext in the communicative foreign language classroom. An output-based approach was adopted, vindicating writing as a major tool for grammar and vocabulary learning. A group of post-A level undergraduate language students collaborated on literary hypertexts over a period of ten weeks. Learners were formally taught literary forms and techniques which they applied in a variety of creative writing activities, either individually or in small groups. The classroom environment was kept pressure-free, with the intention to stimulate creativity, collaborative learning and peer feedback. Linguistic performance data was obtained from written output as well as tape-recorded interviews and, following the habits of action research, videoed classroom activities. The data was analysed with regard to students' discourse and autonomous learning strategies, error frequency and distribution as well as eloquence in style and lexicon. Results show that collaborative, creative writing in hypertext format stimulates motivation, confidence, and autonomy, as well as helping to improve grammatical competence, particularly amongst intermediate and advanced learners. Student responses further suggest using literary hypertext receptively and productively at school level, as it combines linguistic, IT, and literary skills.
Smooth Compactly Supported Solutions of Some Underdetermined Elliptic PDE, with Gluing Applications

We give sufficient conditions for some underdetermined elliptic PDE of any order to construct smooth compactly supported solutions. In particular we show that two smooth elements in the kernel of certain underdetermined linear elliptic operators P can be glued in a chosen region in order to obtain a new smooth solution. This new solution is exactly equal to the initial elements outside the gluing region. This result completely contrasts with the usual unique continuation for determined or overdetermined elliptic operators. As a corollary we obtain compactly supported solutions in the kernel of P and also solutions vanishing in a chosen relatively compact open region. We apply the result for natural geometric and physics contexts such as divergence free fields or TT-tensors.
Management of low back pain by physical therapists in quebec: how are we doing?

PURPOSE In this study, we characterized physiotherapists' attitudes and beliefs about the bio-psychosocial problem of low back pain (LBP), their use of clinical practice guidelines (CPGs), and the extent to which their advice and treatment is in line with best-evidence CPGs. METHODS One hundred eight physiotherapists completed an online survey that included questionnaires exploring the strength of physiotherapists' biomedical and bio-psychosocial orientations toward the management of LBP: the Pain Attitudes and Beliefs Scale for Physiotherapists and the Attitudes to Back Pain Scale for musculoskeletal practitioners. In addition, participants responded to questions about treatment recommendations for patients in two vignettes. RESULTS Only 12% of respondents were aware of CPGs. Physiotherapists with a stronger biomedical orientation scored the severity of spinal pathology higher in the patient vignettes. A stronger biomedical orientation was also associated with disagreement with recommendations to return to usual activity or work. CONCLUSIONS The results suggest limited awareness by physiotherapists of best-evidence CPGs and contemporary understandings of LBP that support early activation and self-management. Research to better understand and facilitate the implementation of best-evidence professional education and clinical practice is an urgent priority.
The Stress of Multiple Roles: The Case for Role Strain among Married College Women.

Stress-related variables were analyzed as possible predictors of role strain among a sample of married college women. The exploratory study was conducted among married women students in an urban university's home economics-related department. Findings are suggestive of potentially stressful concerns to women students which advisors and counselors may wish to pursue both in counseling sessions and additional research studies.
Electrocardiographic Abnormalities That Predict Coronary Heart Disease Events and Mortality in Postmenopausal Women: The Women’s Health Initiative

Background— Information is limited about the independent prognostic value of repolarization abnormalities in women. Methods and Results— We evaluated hazard ratios for ECG variables for combined fatal and nonfatal coronary heart disease (CHD) events and for CHD mortality using Cox regression in 38 283 Women’s Health Initiative (WHI) participants during up to 9.2 years of follow-up. All risk models were adjusted for demographic, clinical, and therapeutic variables. Evaluated as single ECG variables, wide QRS/T angle and ECG-demonstrated myocardial infarction (ECG-MI) were the strongest predictors of CHD events, with hazard ratios (95% CI) of 1.90 (1.50 to 2.42) and 1.62 (1.29 to 2.03), respectively. Six other repolarization variables were also significant, strong predictors of CHD events. Wide QRS/T angle, ECG-MI, and QT prolongation appeared as dominant predictors when evaluated simultaneously with other ECG variables in a multiadjusted risk model. QRS/T angle, ECG-MI, and high QRS nondipolar voltage were the strongest predictors of CHD mortality, with hazard ratios of 2.70, 2.41, and 2.18, respectively. The risk increase ranged from 63% to 95% for the other 4 significant predictors. Five ECG abnormalities were identified as dominant mortality risk predictors: wide QRS/T angle, ECG-MI, high QRS nondipolar voltage, reduced heart rate variability, and QT prolongation (in the cardiovascular disease–free group only). Conclusions— Ventricular repolarization abnormalities in postmenopausal women are as important predictors of CHD events and CHD mortality as ECG-MI and other QRS abnormalities. Repolarization variables and QRS nondipolar voltage warrant attention in future investigations.
Exploring Differences in Males' and Females' Processing Strategies

Existing research suggests that, relative to males, females often are more concerned with the particulars of message claims when processing advertising messages. This research examines how males process messages, when gender differences in processing are likely to occur, and whether variance In either information availability (the extent of message encoding) or information accessibility (the richness of message encoding) is likely to mediate such differences. The findings suggest that whether gender differences in processing occur depends on the nature of the response task and the level of cue incongruity contained in the message. Differences in the accessibility of message cues and in the genders' likelihood of using alternative processing strategies seem likely to account for these findings.

On the State of Computing in Statistics Education: Tools for Learning and for Doing

This paper lays out the current landscape of tools used in statistics education. In particular, it considers graphing calculators, spreadsheets, applets and microworlds, standalone educational software, statistical programming tools, tools for reproducible research and bespoke tools. The strengths and weaknesses of the tools are considered, particularly in the context of McNamara (2016)'s list of attributes for a statistical computing tool. Best practices for computing in introductory statistics are suggested.
DIET AND CANCER OF THE STOMACH: A CASE‐CONTROL STUDY IN GREECE

A case‐control study focusing on the role of diet in the etiology of gastric cancer was undertaken in Piraeus, the sister city of Athens, in a population characterized by ethnic homogeneity but substantial heterogeneity with respect to dietary habits. The case series consisted of 110 consecutive patients with histologically confirmed adenocarcinoma of the stomach, admitted to two teaching hospitals during a 3‐year period; the control series consisted of orthopedic patients admitted to a nearby hospital for accidents, fractures and other orthopedic disorders, during the same time period. Dietary histories concerning the frequency of consumption (per month or per week) of about 80 food items were obtained by the same interviewer. Cases reported significantly less frequent consumption of lemons, oranges, brown bread, and raw, salad‐type vegetables (particularly lettuce, onions and cucumbers) and, independently, significantly more frequent consumption of pasta, beans and nuts. A relative risk of about 40 was found between extreme quintiles when the above 9 food Items were combined in a linear risk score. Use of an index constructed from the study material will clearly overestimate the level of risk between the extreme quintiles, but nevertheless the risk differences appear noteworthy, and consistent with the international variation in the incidence of gastric cancer. No significant associations were found with alcoholic beverages, coffee or tea.
DOES STRESS ENHANCE OR IMPAIR SELECTIVE ATTENTION? THE EFFECTS OF STRESS AND PERCEPTUAL LOAD ON NEGATIVE PRIMING

Two negative priming (NP) experiments investigated the effects of stress and load on selective attention. In Experiment 1, in which stress was relatively low under all conditions, load was manipulated with two levels of prime-target discriminability. The NP effect was smaller in the high- than in the low-load condition. Experiment 2 contained both a low-stressed group and a high-stressed one. For each group, half of the trials were with low-load primes and half with high-load ones, as in Experiment 1. As in Experiment 1, with low stress, NP was reduced in the high- as compared to the low-load condition. However, with high stress, the effect was in the opposite direction. There was more NP in the high- than in the low-load condition. The cross-over interaction between the effects of load and stress on NP suggests that stress increases interference from irrelevant information, and thus, impairs selective attention.
Evolving Fault Tolerance On An Unreliable Technology Platform

One of the key areas in which evolvable hardware has been shown to excel is in achieving robust analogue and digital electronics. In this paper this domain is investigated further by manipulation of the digital abstraction. Some of the strict requirements of digital gates are relaxed in order to increase the complexity of the functionality available to evolution in order to evolve fault tolerant designs. Results from extrinsic evolution of a 2-by-2 bit multiplier, based on CMOS technology under various noise and fault conditions, illustrate the suitability of the messy gate methodology used herein for evolution of a fault tolerant design.
IMPORT , R & D SPILLOVER AND EXPORT : A STUDY OF AUTOMOBILE SECTOR IN INDIA WORKING PAPER 98 / 2015

We examine the importance of a firm‟s R and D activity, technology import and intra-sectoral R and D spillovers on the decision to export and export intensity using firm level panel data for the Indian automobile sector from 2000-2014. R and D and technology import activities are found to be important determinants of export activity. There is evidence that R and D spillovers exert positive effects on firms‟ export intensity and decision to export. In addition to these results, firm age and size are nonlinearly related to export decision and export intensity. Energy efficiency plays important role in export behavior for firms that are continuously exporting and those who are exporting at least for one year.
Selective determinants of inositol 1,4,5-trisphosphate and adenophostin A interactions with type 1 inositol 1,4,5-trisphosphate receptors

BACKGROUND AND PURPOSE Adenophostin A (AdA) is a potent agonist of inositol 1,4,5‐trisphosphate receptors (IP3R). AdA shares with IP3 the essential features of all IP3R agonists, namely structures equivalent to the 4,5‐bisphosphate and 6‐hydroxyl of IP3, but the basis of its increased affinity is unclear. Hitherto, the 2′‐phosphate of AdA has been thought to provide a supra‐optimal mimic of the 1‐phosphate of IP3.
Hardness perception by tapping: Effect of dynamic stiffness of objects

Humans can judge the hardness of an object by tapping its surface using a fingertip. The damped natural vibration caused by tapping is a vibrotactile cue for hardness perception. We investigated how dynamic characteristics of an object or vibration influence the hardness perceived by tapping. Using multivariate analyses, the subjectively reported hardness was linked with the dynamic stiffness of an object. Dynamic stiffness, which characterizes the impulsive response of an object, was acquired across 40–1,000 Hz for fourteen types of material cuboid through a hammering test. These blocks were also ranked by seven participants based on their hardness perceived when the participants tapped them with a finger. It was found that the dynamic stiffness did not equally affect the hardness perception across the wide frequency range. Its sensitivity displayed a peak around 200–400 Hz and decreased or disappeared at greater frequency bands in which human perceptual capability is limited.
Ostwald Ripening in Thin Film Equations

Fourth order thin film equations can have late stage dynamics that are analogous to the classical Cahn–Hilliard equation. We undertake a systematic asymptotic analysis of a class of equations that describe partial wetting with a stable precursor film introduced by intermolecular interactions. The limit of small precursor film thickness is considered, leading to explicit expressions for the late stage dynamics of droplets. Our main finding is that exchange of mass between droplets characteristic of traditional Ostwald ripening is a subdominant effect over a wide range of kinetic exponents. Instead, droplets migrate in response to variations of the precursor film. Timescales for these processes are computed using an effective medium approximation to the reduced free boundary problem, and dynamic scaling in the reduced system is demonstrated.
Beyond Shape: How You Learn about Objects Affects How They Are Represented in Visual Cortex

Background Experience can alter how objects are represented in the visual cortex. But experience can take different forms. It is unknown whether the kind of visual experience systematically alters the nature of visual cortical object representations. Methodology/Principal Findings We take advantage of different training regimens found to produce qualitatively different types of perceptual expertise behaviorally in order to contrast the neural changes that follow different kinds of visual experience with the same objects. Two groups of participants went through training regimens that required either subordinate-level individuation or basic-level categorization of a set of novel, artificial objects, called “Ziggerins”. fMRI activity of a region in the right fusiform gyrus increased after individuation training and was correlated with the magnitude of configural processing of the Ziggerins observed behaviorally. In contrast, categorization training caused distributed changes, with increased activity in the medial portion of the ventral occipito-temporal cortex relative to more lateral areas. Conclusions/Significance Our results demonstrate that the kind of experience with a category of objects can systematically influence how those objects are represented in visual cortex. The demands of prior learning experience therefore appear to be one factor determining the organization of activity patterns in visual cortex.
The Impacts of Ethical Ideology, Materialism, and Selected Demographics on Consumer Ethics: An Empirical Study in China

This study attempts to investigate the relationships among the ethical beliefs of Chinese consumers and orientations based on attitudinal attributes: materialism and moral philosophies (idealism and relativism). In addition, this study examines Chinese consumers' ethical beliefs in relation to five selected demographic characteristics (gender, age, religion, family income and education). Based on this exploratory study of 284 Chinese consumers, the following statistically significant findings were discovered. First, Chinese consumers regard that a passively benefiting activity is more ethical, but actively benefiting from an illegal or a questionable activity is unacceptable. Second, the two dimensions of passively benefiting and no harm/no foul can be used to distinguish the consumers who endorse higher levels of idealism or relativism. Third, Chinese consumers with a high level of materialism are more likely to actively benefit from illegal and questionable activities, and the passively benefiting actions. Finally, the more ethical Chinese consumers seem to be younger, be religious, and have a lower family income.
Equity Sensitivity and Organizational Citizenship Behavior in a Team Environment

This study examines the relationship between the equity sensitivity orientation of individuals and their exhibition of organizational citizenship behaviors in a team setting. Equity sensitivity theory posits that individuals differ in their equity orientation. Individuals on the benevolent end of the scale do not mind if they are giving more than they are receiving. Conversely, individuals at the entitled end of the spectrum prefer to be in a situation where they are receiving more than they are giving. Participants were administered the Equity Sensitivity instrument (ESI) at the beginning of a team project to determine their equity orientation. At the conclusion of the team project, participants were asked to evaluate their teammates' citizenship behaviors. Through a regression analysis, a significantly positive relationship was found between equity sensitivity scores and team citizenship behaviors. Those participants holding a more benevolent orientation were significantly more likely to exhibit citizenship behaviors as reported by their teammates.
Relationship Between Linguistic Antonyms in Momentary and Retrospective Ratings of Happiness and Sadness

Momentary ratings of affective states with a pair of strict antonyms ("happy" vs. "sad") were studied with an experience- sampling method in a group of 110 participants during 14 consecutive days at 7 randomly determined occasions per day. Before and after the experimental session participants also retrospectively rated how happy or sad they had been during the previous 2 weeks. Multilevel analysis showed that, at the level of single measurement trials, the momentary ratings of happiness and sadness were moderately negatively correlated (r = -.32, p < .001). A between-subject correlation of the two antonyms, however, was in a positive direction (r = .13, p = .123). Participants experienced mixed feelings during a considerable number of measurement trials, whereas the tendency to feel mixed emotions was predicted by all Big Five personality traits except Agreeableness. A configural frequency analysis (CFA) demonstrated that, although there was no strict bipolarity between momentary ratings of happiness and sadness, they were nevertheless used in an exclusive manner in many occasions.
