New findings on unconscious versus conscious thought in decision making: additional empirical data and meta-analysis.

Ninety-eight Australian students participated in a functional replication of a study published by Dijksterhuis et al. (2006). The results indicated that unconscious thought does not necessarily lead to better normative decision making performance than conscious thought, which is contrary to the results found in Dijksterhuis et al. Since other studies showed a positive, though statistically not significant, effect for unconscious thought, a meta-analysis comprising a total of 17 experiments was conducted. It suggests that there is little evidence for an advantage to normative decision making using unconscious thought. However, a discussion of potential moderators shows that further study would help to identify situations in which unconscious thought is truly helpful and those in which it is not.
Bone and Joint Infections due to Haemophilus parainfluenzae: Case Report and Review of the Literature

Haemophilus parainfluenzae is a normal inhabitant of the human respiratory tract. However it is an increasingly recognized pathogen in invasive infections, particularly in the immunocompromised host and where there is disruption of the normal skin or mucosal barriers. We present a case of a 56-year-old female with a history of asplenia who developed H. parainfluenzae septic arthritis of the hip following an intra-articular steroid injection. We also summarize previously reported cases of bone and joint infections caused by H. parainfluenzae.
FROM A DISTANCE: A PHENOMENOLOGICAL STUDY OF THE LIVED EXPERIENCE OF TELECOMMUTERS WORKING REMOTELY IN VIRTUAL TEAMS

In this paper, the social and emotional experience of telecommuters working remotely in interdependent virtual teams is explored through a phenomenological inquiry into participants'ʹ lived experiences. The problem this study addresses is a lack of understanding about the process by which individuals subjectively experience remote work in virtual teams. The research methodology for this study is qualitative—drawing data from interviews of 10 participants. The participants for this study represented a variety of industries and organizations. They were telecommuters who worked remotely more than 80% of the time, had a minimum of one year’s experience, and collaborated with others to develop a shared work product. Data analysis surfaced the two major themes of the social and the emotional experience of participants, as well as subthemes that identify contextual, structural, and personal factors that shaped their experiences.
New lectins from aspergilli and their carbohydrate specificity

Lectin activity was assessed in sixteen Aspergillius species using human A, B, O, AB, rabbit, goat, pig and sheep erythrocytes. Neuraminidase and protease treated blood group O erythrocytes were also used to evaluate lectin activity from all the cultures unable to agglutinate native red blood cells. Lectin activity was revealed from Aspergillus acristatus, A. gorakhpurensis, A. panamensis and A. carbonarius extracts, while undiluted extract of A. fischeri showed weak haemagglutination. Lectin activity was expressed after 5 days of growth by A. acristatus, A. gorakhpurensis, A. panamensis and A. carbonarius and after 8 days of cultivation a sharp decline in lectin activity was observed. Higher titres were observed from these species with enzymatically modified blood type O erythrocytes. A variety of carbohydrates were used to study their minimum inhibitory concentration capable of inhibiting haemagglutination. Porcine stomach mucin was found to be the most potent inhibitor of all the lectins. A. gorakhpurensis lectin showed high specificity for chondroitin-6-sulphate and N-acetyl-D-galactosamine. Significant specificity for L-fucose, D-arabinose and 2-deoxy-D-ribose was identified with A. panamensis lectin. Low concentrations of 0.625 mM of D-galactosamine HCl and 0.12 mg/mL of chondroitin-6-sulphate were found optimal to prevent haemagglutination of A. carbonarius extract. A. carbonarius lectin was partially purified 2.75-fold using ammonium sulphate precipitation, dialysis and ultrafiltration. It was found to be stable upto 40°C and within the pH range of 7.0–8.0. Lectin activity was not affected by guanidine-HCl, while it was reduced to half after incubation with urea and thiourea after 24 h.
The managerial labor market and the governance role of shareholder control structures a

We simultaneously analyze two mechanisms of the managerial labor market: CEO turnover and monetary remuneration schemes. Sample selection models and hazard analyses are applied to a random sample of 250 firms listed on the London Stock Exchange. Our approach yields novel results (compared to earlier UK research): the managerial remuneration and the termination of labor contracts play an important role in mitigating agency problems between managers and shareholders. Both the CEOs’ industry-adjusted monetary compensation and CEO replacement are strongly performancesensitive. There is little evidence of outside shareholder monitoring whereas CEOs with strong voting power successfully resist replacement irrespective of corporate performance. CEO remuneration is more sensitive to stock price performance in firms with strong outside shareholders whereas remuneration in insider-dominated firms is more sensitive to measures of accounting returns. When stock prices decrease, CEOs seem to compensate disappointing stock performance by augmenting the cash-based compensation package. Finally, the presence of a remuneration committee has no significant impact on remuneration. JEL classification: G30; G32; G34; J33
Genome-wide characterization reveals complex interplay between TP53 and TP63 in response to genotoxic stress

In response to genotoxic stress the TP53 tumour suppressor activates target gene expression to induce cell cycle arrest or apoptosis depending on the extent of DNA damage. These canonical activities can be repressed by TP63 in normal stratifying epithelia to maintain proliferative capacity or drive proliferation of squamous cell carcinomas, where TP63 is frequently overexpressed/amplified. Here we use ChIP-sequencing, integrated with microarray analysis, to define the genome-wide interplay between TP53 and TP63 in response to genotoxic stress in normal cells. We reveal that TP53 and TP63 bind to overlapping, but distinct cistromes of sites through utilization of distinctive consensus motifs and that TP53 is constitutively bound to a number of sites. We demonstrate that cisplatin and adriamycin elicit distinct effects on TP53 and TP63 binding events, through which TP53 can induce or repress transcription of an extensive network of genes by direct binding and/or modulation of TP63 activity. Collectively, this results in a global TP53-dependent repression of cell cycle progression, mitosis and DNA damage repair concomitant with activation of anti-proliferative and pro-apoptotic canonical target genes. Further analyses reveal that in the absence of genotoxic stress TP63 plays an important role in maintaining expression of DNA repair genes, loss of which results in defective repair.
Quantum interference control of electrical currents in GaAs

In an earlier publication, preliminary observations of the generation of electrical currents were reported in GaAs and low-temperature-grown GaAs (LT-GaAs) at 295 K using quantum interference control of single- and two-photon band-band absorption of 1.55- and 0.775-/spl mu/m ultrashort optical pulses. Time-integrated currents were measured via charge collection in a metal-semiconductor-metal (MSM) electrode structure. Here we present detailed characteristics of this novel effect in terms of a simple circuit model for the MSM device and show how the injected current depends on MSM parameters as well as optical coherence, power, and polarization. For picosecond pulse excitation with peak irradiance of only 30 MW/cm/sup -2/ (1.55 /spl mu/m) and 9 kW/cm/sup -2/ (0.775 /spl mu/m), peak current densities of /spl sim/10 A/cm/sup -2/ at peak carrier densities of 10/sup 15/ cm/sup -3/ are inferred from the steady-state signals. This compares with 50 A/cm/sup -2/ predicted theoretically; the discrepancy mainly reflects inefficient charge collection at the MSM electrodes.
An Experimental Evaluation of the Impact of System Sequence Diagrams and System Operation Contracts on the Quality of the Domain Model

The Unified Modeling Language (UML) is an object-oriented analysis and design language widely used to created artifacts during the software system lifecycle. UML being a standard notation, without specific guidelines as to how to use it, it must be applied in the context of a specific software development process. The Unified Process (UP) is one such process, extensively used by the object-oriented community, which delivers software best practices via guidelines for all software lifecycle activities. The UP suggests many artifacts to be produced during the software lifecycle. But many practitioners are reluctant to use those artifacts as they question their benefits. System Sequence Diagrams and System Operation Contracts are artifacts, suggested by Larman in his well-known methodology, to complement standard UP artifacts with the intent of better understanding the input and output events related to the system being designed. This paper presents the results of controlled experiments that investigate the impact of using these artifacts during software development. One way to do that is to study the extent to which those artifacts improve the quality of the Domain Model or reduce the effort necessary to complete this Domain Model. Results show that the use of those artifacts mildly improves the quality of the Domain Model, as long as sufficient training is provided. On the other hand, there is no noticeable evidence that those two artifacts reduce the time to produce the Domain Model.
The role of stakeholders as a competitive advantage in the formulation of antiquity museum strategies in Egypt

ABSTRACT Although competitive advantage is a business concept that helps an organisation outperform its competitors, this concept can be usefully applied to non-profit organisations such as museums since each possesses unique advantages. The research objective is to investigate all relevant stakeholders’ roles as a competitive advantage in the formulation of antiquity museums’ strategies in Egypt. The author addresses three main stakeholder groups: visitors, governing and managing bodies, and community members. Visiting stakeholders’ interests and roles in creating a competitive advantage are explored via questionnaires; semi-structured interviews are carried out with governing and community stakeholders groups; and an explanation of each unique role is clarified. Moreover, each stakeholder role that is in need of improvement is highlighted. Finally, stakeholders’ proposals to improve their role in achieving a better competitive advantage are presented.
Federal Reserve Bank of Dallas Globalization and Monetary Policy Institute How Successful Is the G7 in Managing Exchange Rates?

The paper assesses the extent to which the Group of Seven (G7) has been successful in its management of major currencies since the 1970s. Using an event-study approach, the paper finds evidence that the G7 has been overall effective in moving the US dollar, yen and euro in the intended direction at horizons of up to three months after G7 meetings, but not at longer horizons. While the success of the G7 is partly dependent on the market environment, it is also to a significant degree endogenous to the policy process itself. The findings indicate that the reputation and credibility of the G7, as well as its ability to form and communicate a consensus among individual G7 members, are important determinants for the G7's ability to manage major currencies. The paper concludes by analyzing the factors that help the G7 build reputation and consensus, and by discussing the implications for global economic governance. for comments and discussions, as well as Martin Skala for help with some of the data series. The views expressed in this paper are those of the author and do not necessarily reflect the views of the European Central Bank, the Federal Reserve Bank of Dallas or the Federal Reserve System.
Extending the nomological network of the organizational citizenship behavior: moderating effect of work family conflict self efficacy on the relationship between organizational citizenship behavior and work family conflict

Abstract: Studies on organizational citizenship behavior (OCB) mainly focus on the positive effects, whereas the negative effects of such behavior for employees seem to be not well addressed. Work-family conflict (WFC) may be one of important negative consequences of OCB. The extent to which OCB is related to WFC, may be depending on the level of the work family conflict self efficacy (WFCSE) that employees have. This study examines the moderating effect of WFCSE on the relationship between OCB and WFC. A sample of employees from eastern region of Sri Lanka participated in this study. The study indicates a positive relationship between OCB and WFC. More specifically, results also indicate that the positive relationship between OCB and WFC was moderated by WFCSE. Further the results also revealed that while WFCSE play as a moderator, the relationship between OCB and WFC was stronger for employees with low levels of WFCSE. Implications for future research are also discussed.
Unbiased Analysis of TCRα/β Chains at the Single-Cell Level in Human CD8+ T-Cell Subsets

T-cell receptor (TCR) α/β chains are expressed on the surface of CD8+ T-cells and have been implicated in antigen recognition, activation, and proliferation. However, the methods for characterization of human TCRα/β chains have not been well established largely because of the complexity of their structures owing to the extensive genetic rearrangements that they undergo. Here we report the development of an integrated 5′-RACE and multiplex PCR method to amplify the full-length transcripts of TCRα/β at the single-cell level in human CD8+ subsets, including naive, central memory, early effector memory, late effector memory, and effector phenotypic cells. Using this method, with an approximately 47% and 62% of PCR success rate for TCRα and for TCRβ chains, respectively, we were able to analyze more than 1,000 reads of transcripts of each TCR chain. Our comprehensive analysis revealed the following: (1) chimeric rearrangements of TCRδ-α, (2) control of TCRα/β transcription with multiple transcriptional initiation sites, (3) altered utilization of TCRα/β chains in CD8+ subsets, and (4) strong association between the clonal size of TCRα/β chains and the effector phenotype of CD8+ T-cells. Based on these findings, we conclude that our method is a useful tool to identify the dynamics of the TCRα/β repertoire, and provides new insights into the study of human TCRα/β chains.
GaN HEMT based Doherty amplifier for 3.5-GHz WiMAX applications

We have implemented a Doherty amplifier for 3.5- GHz world interoperability for microwave access (WiMAX) applications using Eudyna 90-W (P3dB) gallium-nitride (GaN) high electron mobility transistor (HEMT) because of the poor efficiency of a standard class AB amplifier when the linearity performance is good. The load modulation performance of the GaN HEMT device for the Doherty operation is rather moderate but workable. The linearity is improved using the in-band error cancellation technique of the Doherty amplifier. The implemented Doherty amplifier has been designed at an average output power of 43 dBm, backed-off about 8 dB from the 51 dBm (P3dB). For WiMAX signal with 28 MHz signal bandwidth, the measured drain efficiency of the amplifier is 27.8%, and the measured relative constellation error (RCE) is -33.17 dB, while those of the comparable class AB amplifier are 19.42% and -24.26 dB, respectively, at the same average output power level.
Investigation of Solar Proton Access Into the Inner Magnetosphere on 11 September 2017

In this study, access of solar energetic protons to the inner magnetosphere on 11 September 2017 is investigated by computing the reverse particle trajectories with the Dartmouth geomagnetic cutoff code (Kress et al., 2010). The maximum and minimum cutoff rigidity at each point along the orbit of Van Allen Probe A is numerically computed by extending the code to calculate cutoff rigidity for particles coming from arbitrary direction. Pulse height analyzed (PHA) data have the advantage of providing individual particle energies and effectively excluding background high‐energy proton contamination. This technique is adopted to study the cutoff locations for solar protons with different energy. The results demonstrate that cutoff latitude is lower for solar protons with higher energy, consistent with low‐altitude vertical cutoffs. Both the observations and numerical results show that proton access into the inner magnetosphere depends strongly on angle between particle arrival direction and magnetic west. The numerical result is approximately consistent with the observation that the energy of almost all solar protons stays above the minimum cutoff rigidity.
EVALUATION OF ANTI-NUTRITIONAL FACTORS IN HOP EXTRACTS AND EXTRACT FROM AZADIRACHTA INDICA AS POTENTIAL SUBSTITUTE IN THE NIGERIAN BEER INDUSTRY

The anti-nutritional factors in Azadirachta indica (neem) as contrasted to hops were carried out in terms of their methanolic extracts. These factors (trypsin inhibitors, phytate, cardiac glycoside, oxalate, cyanogenic glycoside and hydrogen cyanide) were screened using standard methods. The result of the assay revealed that trypsin inhibitors ranged from 6.45-17.30%, phytate ranged from 0.99% to 1.68% while cardiac glycoside ranged from 3.5% to 6.0% and the concentration of oxalate ranged from 0.0405mg/100g to 0.1020mg/100g, cyanogenic glycoside ranged from 0.216ppm to 0.810ppm while hydrogen cyanide ranged from 0.540ppm to 1.404ppm. It was established from ranking that A. indica was closer to isomerized hop extract than to hop leaf extract in the content of anti-nutritional factors. Hence, the extract from A. indica could be used as suitable substitute for hops in beer brewing.
Co-emergence: an art-full dance of inquiry into artists’ experiences of making art

ABSTRACT This paper offers an account of how women and gender non-conforming people living with mind/body differences connected and changed during a project of creating a dramatic performance intended to shift understandings of disabilities and differences for various communities, including health professionals. Insights from interviews with artist participants are presented in three themes: collective unearthing, carefully bringing forth with others, and embracing the newly tangible. Our insight at this point is that disability-affirmative artistic processes create an inter- and intra-relational space that invites generative learning through self- and critical reflection.
Does Decentralization Lead to School Improvement? Findings and Lessons from Research in West-Africa

Abstract Decentralization is a fashionable reform, adopted by many countries with different characteristics. There are doubts, though, about its objectives and impact. Did inspiration come from a desire to improve quality or from a need to share the financial burden? Does it not increase disparities and the workload for local officials and headteachers? Against this background, the International Institute for Educational Planning, in collaboration with ministries of education, a national institute and the NGO Plan, co-ordinated research on the challenges that local offices and schools encounter. Results are partly disheartening, as they indicate the limits to the implementation of decentralization but they also show that successful innovations are taking place. They help to identify principles of good practice: complementarity between actors; equilibrium between their mandate and resources; reform of school supervision; and the need to counterbalance autonomy by an effective accountability framework. One principle stands central: decentralization does not imply that the State is abandoning control, but rather a change in its role.
Community-associated methicillin-resistant Staphylococcus aureus in children treated in Uruguay.

INTRODUCTION Staphylococcus aureus produces a variety of diseases among children, ranging from skin and soft tissue infections to invasive life-threatening diseases. Since 1990, an increasing number of diseases produced by community-associated methicillin-resistant S. aureus (CA-MRSA) isolates have been reported. The aim of this study was to describe the importance and the microbiological characteristics of S. aureus isolates recovered from children treated at the Hospital Pediátrico del Centro Hospitalario "Pereira Rossell" (HP-CHPR); focusing on invasive diseases caused by CA-MRSA isolates, as well as some clinical aspects of the diseases they have produced. METHODOLOGY One hundred and twenty-five S. aureus isolates recovered from the HP-CHPR between 2003 and 2006 from children with invasive (n=89) and superficial diseases (n=36) were included. Genotypic and phenotypic characteristics of S. aureus isolates and relevant clinical aspects of each child were studied. RESULTS CA-MRSA isolates accounted for 73% of all S. aureus recovered from invasive (mainly bone and joint) infections, pneumonia and bacteraemia. The most common CA-MRSA strain recovered from invasive (n=65) and superficial (n=36) diseases had the following features: pulsotype A (type USA1100), SCCmec cassette type IV, Panton-Valentine Leukocidin genes positive, susceptibility to trimethoprim-sulfamethoxazole without the inducible macrolide-lincosamide-streptogramin B (iMLSB) resistance phenotype. No association between genotypic characteristics of invasive CA-MRSA isolates and clinical outcomes was found. CONCLUSIONS CA-MRSA isolates produced a wide spectrum of invasive diseases in a public paediatric hospital between 2003 and 2006. Microbiologic characterization suggests the spread of an adapted CA-MRSA clone lacking erm genes.
Food Insecurity and Academic Disruption Among College Students

Food insecurity is a growing problem among college students, but little is known about how it is related to academic outcomes. We analyze broad demographics of food insecurity at one institution and explore how food insecurity is associated with whether students have neglected their academics, reduced courses, or considered dropping out of college due to their finances. We then discuss programs that may support food insecure students.
Orthostatic Hypotension and Mortality in Elderly Frail Patients

AbstractOrthostatic hypotension (OH) is a common problem in the elderly age group, and some studies have reported an association between OH and increased mortality. We evaluated possible associations between OH and mortality in a retrospective study of frail elderly patients who came for a comprehensive geriatric assessment.The study included all patients ≥65 years who were assessed in the outpatient Comprehensive Geriatric Assessment Unit. Data were collected from the computerized medical record, including blood pressure, sociodemographic data, lifestyle, falls, pulse rate, body mass index, functional and cognitive status, and comorbidity. Data on mortlaity were also collected.The study population consisted of 571 patients who underwent assessment over a 9-year study period. The mean age was 83.7 ± 6.1, 35.9% were males, and 183 (32.1%) were diagnosed with OH. Systolic OH (OHS) was more common than diastolic OH (25.2% vs 15.6%). In univariate analyses, OHS was associated with increased overall mortality. Over the follow-up period, 30.2% of the OHS patients died compared with 22.3% (P = 0.037), but in the Cox models there was no statistically significant associations between OHS and overall mortality. In contrast, age, burden of comorbidity, a low high-density lipoprotein level, and low creatinine clearance were independent predictors of increased overall mortality.In a population of frail elderly patients with a high burden of comorbidity, OH was not an independent risk factor for overall mortality.
