Suzaku X-Ray Study of an Anomalous Source XSS J12270-4859

We report on the results of a Suzaku X-ray observation of XSS J12270� 4859, one of the hard X-ray sources in the INTEGRAL catalogue. This object has been classified as an intermediate polar (IP) by its optical spectra, and a putative X-ray period of � 860 s. With a 30 ks exposure by Suzaku, we obtained a well-exposed spectrum in the 0.2–70 keV band. We conclude against a previous IP classification based on a lack of Fe K˛ emission features in the spectrum and a failure to confirm the previously reported X-ray period. Instead, the X-ray light curve is filled with exotic phenomena, including repetitive flares lasting for � 100 s, occasional dips with no apparent periodicities, spectral hardening after some flares, and bimodal changes pivoting between quiet and active phases. The rapid flux changes, the dips, and the power-law spectrum point toward an interpretation that this is a low-mass X-ray binary. Some temporal characteristics are similar to those in the Rapid Burster and GRO J1744� 28, making XSS J12270� 4859 a very rare object.
The Influence of Individual Differences on Skill in End-User Computing

Abstract:Using survey data from 776 knowledge workers from a university, this exploratory study generates and tests eight propositions concerning the relationship between individual differences and computer skill. A multiple regression analysis showed that the male gender, younger age, more experience with computers, an attitude of confidence regarding computers, lower math anxiety, and a creative cognitive style are individual difference variables associated with higher computer skill. The regression also indicated that the individual difference variables accounted for 56 percent of the variance associated with computer skill. These findings suggest that organizations should manage euc using two complementary processes: a global process and an individual process. The global or organizationwide process would be responsible for areas such as standards, controls, and security. The individual process would address issues such as education and training, selection and recruitment, and the introduction of new t.
Comparing Psychological Guilt and Godly Sorrow: Do Christians Recognize the Difference?

Two studies primarily involving college students were conducted to determine whether or not Christians were able to differentiate Narramore's (1984) distinctions between guilt and Godly sorrow. The first study found that Christians could identify the difference as a function of resulting changes, the person and attitude/action in primary focus, and attitude toward God, three important distinctions in Narramore's model. Another important distinction suggested by Narra more, attitude toward self, was not a discriminating factor. The second study replicated the first and further suggested that mature Christians, as expected, are better at distinguishing between guilt and Godly sorrow than less mature Christians. Though not a direct test of Narramore's model, the results nevertheless provide reasonable support for the distinction between guilt and Godly sorrow.
Disciplinary Differences in Job Satisfaction, Self‐efficacy, Goal Commitment and Organisational Commitment among Faculty Employees in Norwegian Colleges: an empirical assessment of indicators of performance

Abstract Differences in performance indicators among teaching staff in four disciplines in the college sector in Norway are examined. The paper focuses on performance indicators such as job satisfaction, self‐efficacy, goal commitment and organisational commitment in the college sector. Variations in performance indicators between the faculties of nursing, teacher education, engineering and business administration are discussed. The study reveals statistically significant differences in subject‐specific norms. Managerial implications are indicated, and potential directions for further research are discussed.
Cellular Levels of Oxidative Stress Affect the Response of Cervical Cancer Cells to Chemotherapeutic Agents

Treatment of advanced and relapsed cervical cancer is frequently ineffective, due in large part to chemoresistance. To examine the pathways responsible, we employed the cervical carcinoma-derived SiHa and CaSki cells as cellular models of resistance and sensitivity, respectively, to treatment with chemotherapeutic agents, doxorubicin, and cisplatin. We compared the proteomic profiles of SiHa and CaSki cells and identified pathways with the potential to contribute to the differential response. We then extended these findings by comparing the expression level of genes involved in reactive oxygen species (ROS) metabolism through the use of a RT-PCR array. The analyses demonstrated that the resistant SiHa cells expressed higher levels of antioxidant enzymes. Decreasing or increasing oxidative stress led to protection or sensitization, respectively, in both cell lines, supporting the idea that cellular levels of oxidative stress affect responsiveness to treatment. Interestingly, doxorubicin and cisplatin induced different profiles of ROS, and these differences appear to contribute to the sensitivity to treatment displayed by cervical cancer cells. Overall, our findings demonstrate that cervical cancer cells display variable profiles with respect to their redox-generating and -adaptive systems, and that these different profiles have the potential to contribute to their responses to treatments with chemotherapy.
Assessment of thermo-mechanical stresses in Low Temperature Joining Technology

The Low Temperature Joining Technology (LTJT) creates silver joints by a sintering process. It is an alternative die-attach technology to soldering. To initiate the sintering process the temperature has to be raised above ~ 215°C. The quality of a sintered joint is strongly enhanced by applying pressure to the specimen during the process, thus reducing the porosity in the sintered material. After the interconnect process, residual stresses occur in the sintered material, as well as in the joined parts. The examined specimen was a silicon MOSFET attached to a copper substrate at a sintering pressure of 50 MPa. The scope of this paper is to provide information about residual stress after production and thermo-mechanical stresses during thermal cycling. The focus is put on the investigation of the reliability of sintered silver by simulation.
The Role of Perceptual Load in Processing Distractor Faces

It has been established that successful ignoring of irrelevant distractors depends on the extent to which the current task loads attention. However, the previous load studies have typically employed neutral distractor stimuli (e.g., letters). In the experiments reported here, we examined whether the perception of irrelevant distractor faces would show the same effects. We manipulated attentional load in a relevant task of name search by varying the search set size and found that whereas congruency effects from meaningful nonface distractors were eliminated by higher search load, interference from distractor faces was entirely unaffected by search load. These results support the idea that face processing may be mandatory and generalize the load theory to the processing of meaningful and more complex nonface distractors.
RETRACTED: Electrophysiological Evidence for Failures of Item Individuation in Crowded Visual Displays

By the request of the authors, the following two research articles will be retracted from the Journal of Cognitive Neuroscience: 1. Anderson, D. E. , Ester, E. F. , Klee, D. , Vogel, E. K. , & Awh, E. (2014). Electrophysiological evidence for failures of item individuation in crowded visual displays. Journal of Cognitive Neuroscience, 26(10), 2298– 2309. https://dx.doi. org/10.1162/jocn_a_00649. 2. Anderson, D. E. , Bell, T. A. , & Awh, E. (2012). Polymorphisms in the 5-HTTLPR gene mediate storage capacity of visual working memory. Journal of Cognitive Neuroscience, 24(5), 1069–1076. https://dx.doi. org/10.1162/jocn_a_00207. On August 1, 2015, the Office of Research Integrity (ORI) announced a settlement agreement with David E. Anderson, the Respondent (http://ori.hhs.gov/content/ case-summary-anderson-david). On the basis of the Respondent’s admission and an analysis by the University of Oregon, ORI concluded that the Respondent had engaged in research misconduct by falsifying and/or fabricating data in four publications. Those publications were retracted immediately after the release of the ORI findings. Since that time, additional problems have been discovered with Article 1 above. Data points shown in Figure 8 were removed without justification and in contradiction to the analytic approach described in the methods and results. In light of this discovery and of the previous ORI findings, authors Bell and Awh no longer have confidence in the integrity of the data in Article 2. For these reasons, all authors on both articles (including the Respondent) have agreed to the retraction of Articles 1 and 2 above.
Double loop controller design for the vehicle's heading control

In this study, an electrically powered vehicle has been implemented to perform an unmanned ground vehicle purpose. The steering system is modified to automatically control by installing the DC servo motor at the steering wheel shaft. The compass sensor used as the feedback sensor to measure the current heading angle of the vehicle. The autonomous navigation system determines the general sense of direction of travel and sends that information to the vehicle's control system. The objective of this research is to control the heading of a vehicle in the real world environment under the unpredictable and unstructured surrounding. The change of heading direction and the speed of the vehicle influences to the motion of a vehicle. In this work, the double loop controller is designed. The inner loop performs the steering system control and the outer loop archives vehicle's heading control. In the simulation, 2 different conditions are simulated. First, a vehicle is controlled by using the single loop PID controller at the different levels of vehicle's ground speed and also different levels of heading angle input. Second, a vehicle is simulated at the same conditions but replacing the single loop controller with the double loops PD-PID controller. For the experiment, the PD-PID controller is applied to control the heading of a vehicle in tested field with 2 levels of speed.
13-year-olds approach human-robot interaction like adults

Robots are at the evolution stage that will bring them to interact with humans in daily activities. This will lead to a direct contact with all the members of a household. It is important therefore to understand whether a robot behavior designed for adults could fit also the needs of their younger relatives. In particular, in this work we investigate whether the acceptance and basic understanding of robot behaviors changes between the onset of adolescence and adulthood. With a series of video-based tests we address three different aspects of the interaction: a) the a priori expectations of the prospective users on the most appropriate features of an interactive robot; b) their subjective preferences about a humanoid robot verbal and non-verbal behavior in a demonstration task; and c) the quantitative effect of robot gaze and hand motion on the ability of its human partner to understand its goal. The results show a remarkable similarity between teenagers and adults in all the subjective and quantitative metrics considered, suggesting that a robot behavior designed for adults would be probably effective also in the interaction with 13-year-olds. Our findings also underline the high relevance of an appropriate design of robot gaze direction, as both age groups relied substantially on this implicit cue in their understanding of robot goals.
Quantitative Characterization of Functional Anatomical Contributions to Cognitive Control under Uncertainty

Although much evidence indicates that RT increases as a function of computational load in many cognitive tasks, quantification of changes in neural activity related to increasing demand of cognitive control has rarely been attempted. In this fMRI study, we used a majority function task to quantify the effect of computational load on brain activation, reflecting the mental processes instantiated by cognitive control under conditions of uncertainty. We found that the activation of the frontoparieto-cingulate system as well as the deactivation of the anticorrelated default mode network varied parametrically as a function of information uncertainty, estimated as entropy with an information theoretic model. The current findings suggest that activity changes in the dynamic networks of the brain (especially the frontoparieto-cingulate system) track with information uncertainty, rather than only conflict or other commonly proposed targets of cognitive control.
Publications of the Astronomical Society of Australia

Recently the observationally derived stellar-wind mass-loss rates for Wolf-Rayet stars, or massive naked helium stars, have been revised downwards by a substantial amount. We present evolutionary calculations of helium stars incorporating such revised mass-loss rates, as well as mass transfer to a close compact binary companion. Our models reach final masses well in excess of 10 M , consistent with the observed masses of black holes in X-ray binaries. This resolves the discrepancy found with previously assumed high mass-loss rates between the final masses of stars which spend most of their helium-burning lifetime as Wolf-Rayet stars (∼3 M ) and the minimum observed black hole masses (6 M ). Our calculations also suggest that there are two distinct classes of progenitors for Type Ic supernovae: one with very large initial masses ( 35 M ), which are still massive when they explode and leave black hole remnants, and one with moderate initial masses (∼12–20 M ) undergoing binary interaction, which end up with small pre-explosion masses and leave neutron star remnants.
Bimodal fusion of emotional data in an automotive environment

We present a flexible bimodal approach to person dependent emotion recognition in an automotive environment by adapting an acoustic and a visual monomodal recognizer and combining the individual results on an abstract decision level. The reference database consists of 840 acted audiovisual examples of seven different speakers, expressing the three emotions, positive (joy), negative (anger, irritation) and neutral. Concerning the acoustic module, we calculate the statistics of commonly known low-level features. Facial expressions are evaluated by an SVM classification of Gabor-filtered face regions. At the subsequent integration stage, both monomodal decisions are fused by a weighted linear combination. An evaluation of the recorded examples yields an average recognition rate of 90.7% for the fusion approach. This adds up to a performance gain of nearly 4% compared to the best monomodal recognizer. The system is currently used to improve the usability for automotive infotainment interfaces.
Clinical Psychology of Oral Health: The Link Between Teeth and Emotions

The effects of oral health conditions on physical and psychosocial dimensions have been a matter of interest for several authors over the last decades. Nevertheless, literature lacks studies that address the relationship between the oral health–related quality of life (OHRQoL) and emotions. The present study aimed to investigate the psychological impact of oral disorders on people’s emotional well-being, with a particular attention to gender and age differences. Two hundred twenty-nine dental patients in care at private dental clinics were individually tested. One hundred thirty of them were females (56.8%) and 99 males (43.2%), aged between 18 and 83 years (M = 38.11; SD = 16.7). For the evaluation, the Profile of Mood States (POMS) and the Oral Health Impact Profile (OHIP-14) were used. Data were analyzed using Pearson’s correlations, the ANOVA, and the Kruskal–Wallis test. OHRQoL showed several correlations with all the emotions explored, overcoming the well-known relationship with anxiety and depression (p < .05). The degree of OHRQoL produced differences on mood states, which could appear normal, moderately altered, or psychopathological (p < .03). Furthermore, in different life stages, patients showed specific OHRQoL and emotions.

Tuberculosis (TB) case notification rates in Vietnam have stabilized since 2000, but in 2007 were increasing among young adults. The emerging HIV epidemic only partly explains this increase. Other factors are probably involved. We aimed to assess whether rural-to-urban migration is such a factor. We conducted a case-control study at district TB units (DTUs) in Da Nang province, Vietnam, recruiting equal numbers (170) of TB patients aged 15-35 years, TB suspects of the same age in whom TB was excluded, and TB patients of 35 years and older. Risk factors for TB were assessed through interviews using pre-structured questionnaires. Among persons seeking care at DTUs, migration was not a significant risk factor for TB. Young male migrants had a lower risk of TB than other young adults (odds ratio (OR) 0.4; 95% confidence interval (95%CI) 0.03-0.64). Instead, TB was associated with male sex and a higher level of education. Compared to older TB patients, younger TB patients were more likely to be female, have a higher education level and a job involving indoor contacts with other people. Migration does not account for the increase in TB case notification rates among young adults in Vietnam. However, migration cannot be excluded as a risk factor for TB in Vietnam, because migrants may not seek diagnosis and treatment for TB at DTUs.
Production of Electricity during Wastewater Treatment Using a Single Chamber Microbial Fuel Cell

Microbial fuel cells (MFCs) have been used to produce electricity from different compounds, including acetate, lactate, and glucose. We demonstrate here that it is also possible to produce electricity in a MFC from domestic wastewater, while at the same time accomplishing biological wastewater treatment (removal of chemical oxygen demand; COD). Tests were conducted using a single chamber microbial fuel cell (SCMFC) containing eight graphite electrodes (anodes) and a single air cathode. The system was operated under continuous flow conditions with primary clarifier effluent obtained from a local wastewater treatment plant. The prototype SCMFC reactor generated electrical power (maximum of 26 mW m-2) while removing up to 80% of the COD of the wastewater. Power output was proportional to the hydraulic retention time over a range of 3-33 h and to the influent wastewater strength over a range of 50-220 mg/L of COD. Current generation was controlled primarily by the efficiency of the cathode. Optimal cathode performance was obtained by allowing passive air flow rather than forced air flow (4.5-5.5 L/min). The Coulombic efficiency of the system, based on COD removal and current generation, was <12% indicating a substantial fraction of the organic matter was lost without current generation. Bioreactors based on power generation in MFCs may represent a completely new approach to wastewater treatment. If power generation in these systems can be increased, MFC technology may provide a new method to offset wastewater treatment plant operating costs, making advanced wastewater treatment more affordable for both developing and industrialized nations.
Histogram-based foreground object extraction for indoor and outdoor scenes

Extracting foreground objects is an important task in many video processing/analysis systems. In this paper, we propose a technique for foreground object extraction, under static camera condition. In our approach the spatial histogram of a single background image is modeled as Mixture of Gaussians and this model is updated after every few frames. To extract the foreground, input frames are compared with current background frame model and foreground pixels are classified according to intensity differences. To mitigate the errors caused due to movement of the background objects (e.g tree leaves in outdoor scenes), we also incorporate optical flow in an efficient manner. We demonstrate performance of our approach on various indoor and outdoor scenes.
Workplace Bullying and Burnout: The Moderating Effects of Social Support

ABSTRACT This study aims to investigate the moderating effects of social support on the link between workplace bullying and burnout. This correlational study includes 222 employees recruited from various industry sectors. Participants completed the Revised Negative Acts Questionnaire, the Maslach Burnout Inventory, and the Social Support Scale. Colleague and supervisor support moderated the relationship between both work- and person-related bullying with burnout, whereas family and senior management support moderated the links between burnout and person-related and physically intimidating bullying, respectively. High levels of emotional support were associated with greater emotional exhaustion in work-related and overall bullying. Different forms of social support moderated the links between different forms of workplace bullying and different components of burnout. The present findings may inform anti-bullying prevention programs and interventions supporting bullying victims.
Melanoma Cell Lines Adenovirus 5 and Herpes Simplex Virus Type 1 in Human Alkyltransferase Activity , and Reactivation of Methylated-Alkylguanine-DNA 6 O Relationships among Cell Survival

06-AIkylguanine-DNA alkyltransferase (ATase) activity and host cell reactivation (HCR) of 5-(3-methyl-l-triazeno)imidazole^4-carboxamide (MTIC)-methylated viruses were compared in human melanoma cell lines that were sensitive or resistant to killing by the antitumor DNA methylating agent MTIC. Enhanced HCR of adenovirus 5 (defined as the MIT' phenotype) generally showed a semiquantitative correlation with the natural or induced resistance of the host cells to the toxic effects of MTIC and to the level of ATase activity. However, one MTIC-resistant cell line was found (MM 170) which had a low level of ATase and intermediate HCR of adenovirus. The HCR of herpes simplex virus type 1 (I ISV-I ) was enhanced in the Mer* cells that had natural resistance to MTIC compared with Mer" cells. On the other hand, HCR of HSV-1 in MIT' cells with induced resistance to MTIC was similar to that in Mor cells. Neither adenovirus 5 nor HSV-1 infection induced ATase activity in Mcr cells. This indicates that resistance to the toxic effects of methylating agents is not invariably associated with high levels of ATase activity in human melanoma cells. Furthermore, while induction of the Mer+ phenotype from Mer" cells was usually accompanied by the recov ery of ATase activity, induced Mer* cells had less proficient repair than natural MIT' cells, as judged quantitatively by slightly lower cellular resistance and qualitatively by deficient HCR response for HSV-1. These results suggest that the Mer" and induced Mer* cells lack an ATaseindependent DNA repair mechanism. No differences in MTIC-induced DNA repair synthesis or strand breaks were found between the Mor . natural Mer*, and induced Mer* phenotypes. However, UV-induced DNA repair synthesis was higher in the natural Mer* than in the Mer" or induced Mer* cells, both of which had increased cellular sensitivity to the antimetabolites methotrexate and hydroxyurea. These differences may be related to the effects observed with MTIC. A wide range of ATase activities was found in human melanoma biopsy material.
