Subjective Stress and Coping Resources Interact to Predict Blood Pressure Reactivity in Black College Students

This study examined the effects of subjective stress and coping resources on blood pressure reactivity. Sixty-nine Black college students (mean age = 23.58 years) completed the Life Experiences and Stress Scale to explore the subjective stressfulness associated with life events, the Coping Orientations to Problems Experienced Scale to measure usual ways of coping, and a standardized serial addition laboratory challenge during which blood pressure was assessed. Multiple regression analyses revealed that the interactive effects of subjective stress and coping resources predicted diastolic blood pressure reactivity (both p < .025) but not systolic blood pressure reactivity (both p > .10). These significant interaction effects indicated that higher levels of problem-focused coping were related to more marked diastolic blood pressure changes under conditions of high subjective stress and that emotion-focused coping was associated with less exaggerated diastolic blood pressure changes under conditions of low subjective stress. These findings highlight the potential contribution of psychosocial factors to blood pressure reactivity in Blacks.
Unsettled Moments in Settled Discourse: Women Superintendents’ Experiences of Inequality

In this article, the discourse of 12 women superintendents is examined with the expressed aim of determining if patterns in their talk about their superintendency experiences contain events or episodes of inequality. The study’s examination is guided by an adaptation of Swindler’s theory of “settled” and “unsettled” social periods. Qualitative inquiry and analysis methods are used to identify emerging themes or topics of talk. Five topics of talk emerge from the narrative data: power, silence, style, responsibility, and people. Each of these topics is examined for settled and unsettled properties and further analyzed using the lenses of Chase and Bell’s identified strategies to discover how the women treat their experiences of inequality in their discourse.
Dichotomy for the Hausdorff dimension of the set of nonergodic directions

Given an irrational 0<λ<1, we consider billiards in the table Pλ formed by a $\tfrac{1}{2}\times1$ rectangle with a horizontal barrier of length $\frac{1-\lambda}{2}$ with one end touching at the midpoint of a vertical side. Let NE (Pλ) be the set of θ such that the flow on Pλ in direction θ is not ergodic. We show that the Hausdorff dimension of NE (Pλ) can only take on the values 0 and $\tfrac{1}{2}$, depending on the summability of the series $\sum_{k}\frac{\log\log q_{k+1}}{q_{k}}$ where {qk} is the sequence of denominators of the continued fraction expansion of λ. More specifically, we prove that the Hausdorff dimension is $\frac{1}{2}$ if this series converges, and 0 otherwise. This extends earlier results of Boshernitzan and Cheung.
The Impact of Perceived Security on E-Trust, E-Satisfaction and Adoption of Electronic Banking in Nigeria: A Conceptual Review

Studies in the field of information technology and consumer behavior have established that adoption of e-banking is determined by several factors. As discussed in this paper, some of these factors include perceived security, e-satisfaction and e-trust. However, no agreement has been reached among the scholars since the findings of these studies remain inconclusive. This conceptual paper has therefore introduced the mediating effect of e-trust and e-satisfaction in the context of Nigeria with the purpose of enhancing the relationship between e-banking adoption and perceived security. With this attempt, a major gap has been filled theoretically
The Relation Between Differentiation and Social Anxiety: What Can Be Learned from Students and Their Parents?

Abstract The study tested the relation between parents' differentiation and offspring's social anxiety, using a sample of university students and their parents to reflect family patterns across three generations. The main finding confirmed that parents' levels of differentiation (differentiation of self and family differentiation) and social anxiety were positively related to those of their offspring. This lends support to Bowen's (1978; Kerr & Bowen, 1988) contention of transmission of the family emotional process across generations. Moreover, students' social anxiety was found to be inversely related to their parents' levels of differentiation. The importance of addressing family issues in the treatment of individuals with problems related to social anxiety is indicated.
Responses to anomalous data obtained from repeatable experiments in the laboratory

The purpose of this study was to investigate the possible responses to anomalous data obtained from experiments that are repeatable by carrying out additional or alternative experiments in the laboratory. Based on an analysis of responses from scientists to anomalous data taken from identification experiments on the Vinland Map, it was assumed that an additional response—uncertainty about interpretation of the data—should be considered in addition to the other eight responses reported by Chinn and Brewer 1998. It was also assumed that a process of responses containing more than one response is possible for a given subject who is responding to a given piece of anomalous datum in the laboratory. Both assumptions were verified by examining responses of undergraduates to anomalous data obtained from repeatable laboratory experiments. The results of this study show that there are nine categories of responses: ignoring; rejection; uncertainty of validity; uncertainty of interpretation; exclusion; abeyance; reinterpretation; peripheral conceptual change; and conceptual change. Moreover, two categories of processing, anomalous data–final response (A-R process) and anomalous data–[mediators with/without intermediate responses]–final response (A-M-R process), are assessed in this study. It is suggested that science instructors could use the nine categories of responses to understand the learning characteristics of students, and also to use the A-M-R process to design suitable teaching strategies to arrive at meaningful learning. © 2006 Wiley Periodicals, Inc.

Opposing Actions of Sevoflurane on GABAergic and Glycinergic Synaptic Inhibition in the Spinal Ventral Horn

Background The ventral horn is a major substrate in mediating the immobilizing properties of the volatile anesthetic sevoflurane in the spinal cord. In this neuronal network, action potential firing is controlled by GABAA and glycine receptors. Both types of ion channels are sensitive to volatile anesthetics, but their role in mediating anesthetic-induced inhibition of spinal locomotor networks is not fully understood. Methodology/Principal Findings To compare the effects of sevoflurane on GABAergic and glycinergic inhibitory postsynaptic currents (IPSCs) whole-cell voltage-clamp recordings from ventral horn interneurons were carried out in organotypic spinal cultures. At concentrations close to MAC (minimum alveolar concentration), decay times of both types of IPSCs were significantly prolonged. However, at 1.5 MAC equivalents, GABAergic IPSCs were decreased in amplitude and reduced in frequency. These effects counteracted the prolongation of the decay time, thereby decreasing the time-averaged GABAergic inhibition. In contrast, amplitudes and frequency of glycinergic IPSCs were not significantly altered by sevoflurane. Furthermore, selective GABAA and glycine receptor antagonists were tested for their potency to reverse sevoflurane-induced inhibition of spontaneous action potential firing in the ventral horn. These experiments confirmed a weak impact of GABAA receptors and a prominent role of glycine receptors at a high sevoflurane concentration. Conclusions At high concentrations, sevoflurane mediates neuronal inhibition in the spinal ventral horn primarily via glycine receptors, and less via GABAA receptors. Our results support the hypothesis that the impact of GABAA receptors in mediating the immobilizing properties of volatile anesthetics is less essential in comparison to glycine receptors.
Ring Oscillator Based Injection Locked Frequency Divider Using Dual Injection Paths

Ring oscillator based injection locked frequency dividers (ILFD) generally feature higher power efficiency compared to conventional static frequency dividers. However it is difficult for ring oscillator based ILFDs to achieve large division ratio and wide input locking range at the same time. To increase the input locking range, a ring oscillator based ILFD utilizing dual injection technique is proposed in this letter. For this, both tail injection and direct injection are applied in phase such that the output currents of the two mixing processes corresponding to the two injection paths are added constructively at the output frequency ωo and the overall injection efficiency is therefore increased. A differential buffer circuit with dual injection is proposed. Equivalent circuit modeling of the dual injection buffer and mathematical analysis of locking range enhancement are presented. The core ring oscillator consists of 4 stages of the dual injection buffers. It is fabricated in a 65 nm CMOS technology and consumes less than 2 mW with supply voltage of 1.2 V. Its locking range is from 1.2 to 20.7 GHz without any tuning at 0 dBm injection power level. The proposed ILFD is compact with the core only occupying 15 μm × 30 μm and does not need any extra controls, making it suitable for integrated wideband phase locked loop.
Group Embedded Figures Test (GEFT): Individual Differences, Performance, and Learning Effects

A laboratory study was conducted to investigate overall performance and learning effect differences with the Group Embedded Figures Test (GEFT) administered to 48 finance specialists. The study examined these differences based on the effects of several demographic characteristics: age, sex, total time employed with the current employer, total time employed in the current position, level of education, type of position held in the organization, and amount of academic and applied finance experience. Results indicated that total time employed in the organization tended to affect GEFT performance with those employed for fewer years manifesting greater field independence. An overall learning effect, as measured by the average difference score obtained between Parts II and III of the GEFT, was observed for those examinees who had been employed in the organization longer than the average.
Dedifferentiated Endometrioid Adenocarcinoma of the Uterus: Highly Aggressive and Poor Prognostic Tumor

Dedifferentiated endometrioid adenocarcinoma (DEAC) is a recently described, rare uterine neoplasm containing both low-grade endometrioid adenocarcinoma and undifferentiated carcinoma.1 Undifferentiated carcinoma in DEAC may originate secondary to transformation or dedifferentiation of low-grade endometrioid adenocarcinoma and appears to be more aggressive than endometrial endometrioid adenocarcinoma.2 The undifferentiated component in DEAC can be misdiagnosed as the solid component of grade 3 endometrioid adenocarcinoma.3 Therefore, accurate diagnosis of this neoplasm is important in treatment and prognosis. Here we report a case of DEAC of the uterus.
Realization of high aspect ratio silicon microneedles using optimized process for bio medical applications

Silicon microneedles were fabricated extensively for bio-medical applications by using optimized process. The entire process was simulated and resultant micro structures have been analyzed and reported. Microneedle fabrication was carried out in three different etch techniques and the outputs were compared. The optimized structure was obtained by manipulating etch parameters, mask size and isotropy coefficient of etchants. The aspect ratio (AR) of the fabricated microneedles was found to be much higher than that of any other hollow microneedles reported previously. Mechanical strength and fluid flow characteristics were also calculated and the data obtained from the calculations indicated that the structures should be compatible with modern biomedical applications such as drug and gene delivery, protein and DNA injection etc.

Women's Mental Rotation Abilities as a Function of Priming

This study examined how verbal priming of success or failure words influenced the Mental Rotation (MR) performance of women under stereotype threat. Women athletes and non-athletes (N = 67) completed several MR tasks after doing a word scramble that included positive or negative sports terms. The MR performance of athletes was diminished in relation to that of non-athletes when primed with negative sports-related actions. Negative primes also enhanced the performance of non-athletes in relation to their peers who had positive primes, but there were no differences in MR performances under positive priming. Thus, those who identified with a group experienced threat that negatively impacted performance, but non-athletes were unlikely to have been affected by evaluative performance concerns.
Conflict resolution and procedural fairness in Japanese work organizations

: The purpose of this study was to examine short-term and long-term effects of perceived fairness, and to examine relational factors’ effects of procedural fairness in organizational conflicts between employees and supervisors among the Japanese. We asked 154 Japanese employees working in companies to rate their perception of conflicts as well as attitudes towards their own companies. We found that both perception of procedural and distributive fairness produced short-term effects (satisfaction with outcome of conflicts) and long-term effects (positive organizational attitudes). Perceived procedural fairness was increased by appropriate treatment of the supervisors, but our prediction that this effect would be moderated by the employees’ identification with organizations was not supported.
On the Complexity of Bandit and Derivative-Free Stochastic Convex Optimization

The problem of stochastic convex optimization with bandit feedback (in the learning community) or without knowledge of gradients (in the optimization community) has received much attention in recent years, in the form of algorithms and performance upper bounds. However, much less is known about the inherent complexity of these problems, and there are few lower bounds in the literature, especially for nonlinear functions. In this paper, we investigate the attainable error/regret in the bandit and derivative-free settings, as a function of the dimension d and the available number of queries T. We provide a precise characterization of the attainable performance for strongly-convex and smooth functions, which also imply a non-trivial lower bound for more general problems. Moreover, we prove that in both the bandit and derivative-free setting, the required number of queries must scale at least quadratically with the dimension. Finally, we show that on the natural class of quadratic functions, it is possible to obtain a "fast" O(1/T) error rate in terms of T, under mild assumptions, even without having access to gradients. To the best of our knowledge, this is the first such rate in a derivative-free stochastic setting, and holds despite previous results which seem to imply the contrary.
Analytical Guarantees on Numerical Precision of Deep Neural Networks

The acclaimed successes of neural networks often overshadow their tremendous complexity. We focus on numerical precision a key parameter defining the complexity of neural networks. First, we present theoretical bounds on the accuracy in presence of limited precision. Interestingly, these bounds can be computed via the back-propagation algorithm. Hence, by combining our theoretical analysis and the backpropagation algorithm, we are able to readily determine the minimum precision needed to preserve accuracy without having to resort to timeconsuming fixed-point simulations. We provide numerical evidence showing how our approach allows us to maintain high accuracy but with lower complexity than state-of-the-art binary networks.
Identification of a Chrysanthemic Ester as an Apolipoprotein E Inducer in Astrocytes

The apolipoprotein E (APOE) gene is the most highly associated susceptibility locus for late onset Alzheimer’s Disease (AD), and augmenting the beneficial physiological functions of apoE is a proposed therapeutic strategy. In a high throughput phenotypic screen for small molecules that enhance apoE secretion from human CCF-STTG1 astrocytoma cells, we show the chrysanthemic ester 82879 robustly increases expressed apoE up to 9.4-fold and secreted apoE up to 6-fold and is associated with increased total cholesterol in conditioned media. Compound 82879 is unique as structural analogues, including pyrethroid esters, show no effect on apoE expression or secretion. 82879 also stimulates liver x receptor (LXR) target genes including ATP binding cassette A1 (ABCA1), LXRα and inducible degrader of low density lipoprotein receptor (IDOL) at both mRNA and protein levels. In particular, the lipid transporter ABCA1 was increased by up to 10.6-fold upon 82879 treatment. The findings from CCF-STTG1 cells were confirmed in primary human astrocytes from three donors, where increased apoE and ABCA1 was observed along with elevated secretion of high-density lipoprotein (HDL)-like apoE particles. Nuclear receptor transactivation assays revealed modest direct LXR agonism by compound 82879, yet 10 μM of 82879 significantly upregulated apoE mRNA in mouse embryonic fibroblasts (MEFs) depleted of both LXRα and LXRβ, demonstrating that 82879 can also induce apoE expression independent of LXR transactivation. By contrast, deletion of LXRs in MEFs completely blocked mRNA changes in ABCA1 even at 10 μM of 82879, indicating the ability of 82879 to stimulate ABCA1 expression is entirely dependent on LXR transactivation. Taken together, compound 82879 is a novel chrysanthemic ester capable of modulating apoE secretion as well as apoE-associated lipid metabolic pathways in astrocytes, which is structurally and mechanistically distinct from known LXR agonists.
Modelling the ‘learning divide’: Predicting participation in adult learning and future learning intentions 2002 to 2010

This article presents multivariate analyses of the characteristics associated with both participation in adult education and the intention to participate in future learning. It uses questionnaire data from more than 47,000 individuals collected by the National Institute of Adult Continuing Education (NIACE) over the course of nine annual surveys administered between 2002 and 2010. It reviews both recent and historical policy in the area of ‘lifelong learning’ and considers the findings of previous empirical research in the area. The results of the current study support previous findings suggesting that participation in ‘later’ learning is most strongly associated with positive ‘learning dispositions’ and extended participation in initial, full‐time education. While other socio‐economic factors were related to participation in adult learning, the explanatory power of these variables was much weaker. Despite dramatic changes in online technologies and a ‘massification’ of Internet access over the period stu.
Price Bubbles Sans Dividend Anchors: Evidence from Laboratory Stock Markets

We experimentally explore how investor decision horizons influence the formation of stock prices. We find that in long-horizon sessions, where investors collect dividends till maturity, prices converge to the fundamental levels derived from dividends through backward induction. In short-horizon sessions, where investors exit the market by receiving the price (not dividends), prices levels and paths become indeterminate and lose dividend anchors; investors tend to form their expectations of future prices by forward, not backward, induction. These laboratory results suggest that investors' short horizons and the consequent difficulty of backward induction are important contributors to the emergence of price bubbles.
Evidence on global medical travel

Abstract The potential benefits of travelling across national borders to obtain medical treatment include improved care, decreased costs and reduced waiting times. However, medical travel involves additional risks, compared to obtaining treatment domestically. We review the publicly-available evidence on medical travel. We suggest that medical travel needs to be understood in terms of its potential risks and benefits so that it can be evaluated against alternatives by patients who are seeking care. We propose three domains –quality standards, informed decision-making, economic and legal protection – in which better evidence could support the development of medical travel policies.
MGOUN1 Encodes an Arabidopsis Type IB DNA Topoisomerase Required in Stem Cell Regulation and to Maintain Developmentally Regulated Gene Silencing[W]

This work examines the function of MGOUN1 (MGO1) in Arabidopsis stem cell maintenance, showing that mgo1 mutations enhance the specific stem cell defects in hypomorphic wuschel alleles. Positional cloning reveals that MGO1 encodes topoisomerase IB, thereby linking topoisomerase function to the propagation of developmentally regulated gene function. Maintenance of stem cells in the Arabidopsis thaliana shoot meristem is regulated by signals from the underlying cells of the organizing center, provided through the transcription factor WUSCHEL (WUS). Here, we report the isolation of several independent mutants of MGOUN1 (MGO1) as genetic suppressors of ectopic WUS activity and enhancers of stem cell defects in hypomorphic wus alleles. mgo1 mutants have previously been reported to result in a delayed progression of meristem cells into differentiating organ primordia (Laufs et al., 1998). Genetic analyses indicate that MGO1 functions together with WUS in stem cell maintenance at all stages of shoot and floral meristems. Synergistic interactions of mgo1 with several chromatin mutants suggest that MGO1 affects gene expression together with chromatin remodeling pathways. In addition, the expression states of developmentally regulated genes are randomly switched in mgo1 in a mitotically inheritable way, indicating that MGO1 stabilizes epigenetic states against stochastically occurring changes. Positional cloning revealed that MGO1 encodes a putative type IB topoisomerase, which in animals and yeast has been shown to be required for regulation of DNA coiling during transcription and replication. The specific developmental defects in mgo1 mutants link topoisomerase IB function in Arabidopsis to stable propagation of developmentally regulated gene expression.
