Context and alcohol consumption behaviors affect inhibitory control

Contrasting the traditional focus on alcohol-related visual images, this study examined the impact of both alcohol-related auditory cues and visual stimuli on inhibitory control (IC). Fifty-eight participants completed a Go/No-Go Task, with alcohol-related and neutral visual stimuli presented with or without short or continuous auditory bar cues. Participants performed worse when presented with alcohol-related images and auditory cues. Problematic alcohol consumption and higher effortful control (EC) were associated with better IC performance for alcohol images. It is postulated that those with higher EC may be better able to ignore alcohol-related stimuli, while those with problematic alcohol consumption are unconsciously less attuned to these. This runs contrary to current dogma and highlights the importance of examining both auditory and visual stimuli when investigating IC.
Benzofuranyl Esters: Synthesis, Crystal Structure Determination, Antimicrobial and Antioxidant Activities

A series of five new 2‐(1‐benzofuran‐2‐yl)‐2‐oxoethyl 4-(un/substituted)benzoates 4(a–e), with the general formula of C8H5O(C=O)CH2O(C=O)C6H4X, X = H, Cl, CH3, OCH3 or NO2, was synthesized in high purity and good yield under mild conditions. The synthesized products 4(a–e) were characterized by FTIR, 1H-, 13C- and 1H-13C HMQC NMR spectroscopic analysis and their 3D structures were confirmed by single-crystal X-ray diffraction studies. These compounds were screened for their antimicrobial and antioxidant activities. The tested compounds showed antimicrobial ability in the order of 4b < 4a < 4c < 4d < 4e and the highest potency with minimum inhibition concentration (MIC) value of 125 µg/mL was observed for 4e. The results of antioxidant activities revealed the highest activity for compound 4e (32.62% ± 1.34%) in diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, 4d (31.01% ± 4.35%) in ferric reducing antioxidant power (FRAP) assay and 4a (27.11% ± 1.06%) in metal chelating (MC) activity.
What Should Researchers Expect When They Replicate Studies? A Statistical View of Replicability in Psychological Science

A recent study of the replicability of key psychological findings is a major contribution toward understanding the human side of the scientific process. Despite the careful and nuanced analysis reported, the simple narrative disseminated by the mass, social, and scientific media was that in only 36% of the studies were the original results replicated. In the current study, however, we showed that 77% of the replication effect sizes reported were within a 95% prediction interval calculated using the original effect size. Our analysis suggests two critical issues in understanding replication of psychological studies. First, researchers’ intuitive expectations for what a replication should show do not always match with statistical estimates of replication. Second, when the results of original studies are very imprecise, they create wide prediction intervals—and a broad range of replication effects that are consistent with the original estimates. This may lead to effects that replicate successfully, in that replication results are consistent with statistical expectations, but do not provide much information about the size (or existence) of the true effect. In this light, the results of the Reproducibility Project: Psychology can be viewed as statistically consistent with what one might expect when performing a large-scale replication experiment.
Autologous Matrix-Induced Chondrogenesis in the Knee

Objective: Autologous matrix-induced chondrogenesis (AMIC) is a 1-step cartilage restoration technique that combines microfracture with the use of an exogenous scaffold. This matrix covers and mechanically stabilizes the clot. There have been an increasing number of studies performed related to the AMIC technique and an update of its use and results is warranted. Design and methods: Using the PubMed database, a literature search was performed using the terms “AMIC” or “Autologous Matrix Induced Chondrogenesis. ” A total of 19 basic science and clinical articles were identified. Results: Ten studies that were published on the use of AMIC for knee chondral defects were identified and the results of 219 patients were analyzed. The improvements in Knee Injury and Osteoarthritis Outcome Score, International Knee Documentation Committee Subjective, Lysholm and Tegner scores at 2 years were comparable to the published results from autologous chondrocyte implantation (ACI) and matrix ACI techniques for cartilage repair. Conclusions: Our systematic review of the current state of the AMIC technique suggests that it is a promising 1-stage cartilage repair technique. The short-term clinical outcomes and magnetic resonance imaging results are comparable to other cell-based methods. Further studies with AMIC in randomized studies versus other repair techniques such as ACI are needed in the future.
Quantitative analysis of mammalian GIRK2 channel regulation by G proteins, the signaling lipid PIP2 and Na+ in a reconstituted system

GIRK channels control spike frequency in atrial pacemaker cells and inhibitory potentials in neurons. By directly responding to G proteins, PIP2 and Na+, GIRK is under the control of multiple signaling pathways. In this study, the mammalian GIRK2 channel has been purified and reconstituted in planar lipid membranes and effects of Gα, Gβγ, PIP2 and Na+ analyzed. Gβγ and PIP2 must be present simultaneously to activate GIRK2. Na+ is not essential but modulates the effect of Gβγ and PIP2 over physiological concentrations. Gαi1(GTPγS) has no effect, whereas Gαi1(GDP) closes the channel through removal of Gβγ. In the presence of Gβγ, GIRK2 opens as a function of PIP2 mole fraction with Hill coefficient 2.5 and an affinity that poises GIRK2 to respond to natural variations of PIP2 concentration. The dual requirement for Gβγ and PIP2 can help to explain why GIRK2 is activated by Gi/o, but not Gq coupled GPCRs. DOI: http://dx.doi. org/10.7554/eLife.03671. 001
Construct‐Based Approach to Developing a Short, Personality‐Based Measure of Integrity

Covert integrity measures are thought to draw from the Big Five dimensions of conscientiousness, agreeableness, and emotional stability. Using a construct‐based approach, we had subject matter experts identify items from a Big Five personality measure, the Trait Self‐Descriptive Personality Inventory that reflected an operational definition of integrity. The resulting 10 items exhibited a three‐factor structure that corresponded to the three Big five dimensions associated with integrity. Study 1 used primary (N = 388) and archival (N = 429) data sets collected from Canadian Armed Forces recruits to establish the construct validity of the new test. With respect to convergent and discriminant validity, the Integrity scale was related to the Honesty–Humility scale of the HEXACO‐PI and was unrelated to organizational commitment. Hierarchical regression analyses provided evidence that the integrity scale predicted counterproductive work behavior and job performance over and above the Big Five. Study 2 replicated the results of Study 1 using a civilian sample (N = 200). The Integrity scale was related to the Hogan Reliability Index but not to the General Health Questionnaire. It predicted work engagement over and above the Big Five. We also tested the proposition that integrity is a second‐order factor based on conscientiousness, agreeableness, and emotional stability. Structural equation models in both studies confirmed that proposition. We discuss the implications of our results for both theory and practice.
Experiencing work/non-work

The relationships between work and personal life have been on the public, business, and research agenda for about 35 years. Perspectives on these relationships have shifted from a work-family to work-life or work-personal life focus, from a conflict to a balance or enrichment view and, finally, from a segmentation to an integration perspective. This book adopts a HUMANISTIC perspective having individuals in focus. The book explores and provides an understanding of individuals'' work/non-work experiences from a boundary perspective. It analyses and interprets the life stories of six middle-managers. The book theorises individuals'' work/non-work experiences into a model of individuals'' work/non-work experiences. This model shall help individuals to understand processes behind their work/non-work experiences in their private, organizational and societal contexts. This book also concludes that segmenting AND integrating are essential for the harmony between one''s life domains namely one''s work, one''s family, one''s social and one''s private.
Investigation electrical properties of nanofiber polyaniline with molarity dopant variation as polymer conductive

This study investigated the electrical properties of polyaniline nanofiber with molarity dopant variation. The electrical property observed on the polyaniline nanofiber was carried out by using High Precision LCR meter. Polyaniline nanofiber in this study is synthesized by the interfacial polymerization method in 0.32 M Aniline into Toluena with 4mmol APS into HCl solution with molarity between 0.6 M to 2.4 M. The synthesis results were also observed further by Scanning Electron Microscope (SEM). The results of this study indicate that the increase in dopants molarity give effect to the increment of conductivity and diameter fiber of the material.
RCFD: A Novel Channel Access Scheme for Full-Duplex Wireless Networks Based on Contention in Time and Frequency Domains

In the last years, the advancements in signal processing and integrated circuits technology allowed several research groups to develop working prototypes of in–band full–duplex wireless systems. The introduction of such a revolutionary concept is promising in terms of increasing network performance, but at the same time poses several new challenges, especially at the MAC layer. Consequently, innovative channel access strategies are needed to exploit the opportunities provided by full–duplex while dealing with the increased complexity derived from its adoption. In this direction, this paper proposes RTS/CTS in the Frequency Domain (RCFD), a MAC layer scheme for full–duplex ad hoc wireless networks, based on the idea of time–frequency channel contention. According to this approach, different OFDM subcarriers are used to coordinate how nodes access the shared medium. The proposed scheme leads to efficient transmission scheduling with the result of avoiding collisions and exploiting full–duplex opportunities. The considerable performance improvements with respect to standard and state–of–the–art MAC protocols for wireless networks are highlighted through both theoretical analysis and network simulations.

Graph-Based Semi-Supervised Conditional Random Fields For Spoken Language Understanding Using Unaligned Data

We experiment graph-based SemiSupervised Learning (SSL) of Conditional Random Fields (CRF) for the application of Spoken Language Understanding (SLU) on unaligned data. The aligned labels for examples are obtained using IBM Model. We adapt a baseline semisupervised CRF by deﬁning new feature set and altering the label propagation algorithm. Our results demonstrate that our proposed approach signiﬁcantly improves the performance of the supervised model by utilizing the knowledge gained from the graph.
Parallel TDMA Scheduling for Multiple-Destination Wireless Networks

We study transmission strategies in a multiple-source, multiple-destination wireless network. Each source transmits packets that are intended for a particular destination. However, a transmitted packet can cause interference at other destinations. Our primary performance measure is throughput, which we define to be the average number of packets that are successfully received per intended destination per time slot. The sources are first divided into groups, based on the intended destination of their packets. In our parallel method, each group operates according to its own local protocol (e.g., TDMA), concurrently with and independently of the other groups. Our results show the impact of transmission schedules, channel fading, receiver noise, and other-user interference on network performance. We then show that, for given channel statistics and topology configurations, the network performance can be significantly improved when the groups in the network coordinate their transmissions according to an optimal schedule. Further, in many cases, even the use of randomly generated parallel schedules can provide considerably higher performance than traditional TDMA.
Understanding the Dark Side of Domain Parking

Domain parking is a booming business with millions of dollars in revenues. However, it is also among the least regulated: parked domains have been routinely found to connect to illicit online activities even though the roles they play there have never been clarified. In this paper, we report the first systematic study on this "dark side" of domain parking based upon a novel infiltration analysis on domains hosted by major parking services. The idea here is to control the traffic sources (crawlers) of the domain parking ecosystem, some of its start nodes (parked domains) and its end nodes (advertisers and traffic buyers) and then "connect the dots", delivering our own traffic to our end nodes across our own start nodes with other monetization entities (parking services, ad networks, etc) in-between. This provided us a unique observation of the whole monetization process and over one thousand seed redirection chains where some ends were under our control. From those chains, we were able to confirm the presence of click fraud, traffic spam and traffic stealing. To further understand the scope and magnitude of this threat, we extracted a set of salient features from those seed chains and utilized them to detect illicit activities on 24 million monetization chains we collected from leading parking services over 5.5 months. This study reveals the pervasiveness of those illicit monetization activities, parties responsible for them and the revenues they generate which approaches 40% of the total revenue for some parking services. Our findings point to an urgent need for a better regulation of domain parking.
Teachers' Perceptions of ELL Students: Do Their Attitudes Shape Their Instruction?

ABSTRACTThe purpose of this parallel mixed-methodology study was to examine how the perceptions of early childhood teachers toward their early childhood English Language Learners (ELL) shape their pedagogical practices. The study was conducted in 10 early childhood classrooms, ranging from grades pre-K to third, in one suburban school with a culturally and linguistically diverse student population. Quantitative data was gathered through the administration of Pohan and Aguilar's (2001) Professional beliefs about diversity Likert scale. Additionally, qualitative data w`ere collected. Although some survey responses and interviews indicated that participants were aware of and accepting of all students' funds of knowledge and were eager to draw on their students' cultural backgrounds languages, most were ill-equipped or unwilling to differentiate their instruction for ELL students. Implications for inservice teacher professional development to gain understandings of the theories of second language acquisition .
Design of adaptive haptic-enabled virtual reality based system for upper limb movement disorders: A Usability Study

Neurological disorders are major cause of global disease burden. They often impair hand function, a critical element of our day-to-day activities of daily living. Conventional rehabilitation techniques aim to improve one's ability to use affected limbs which are tailored to individual capabilities (performance and stress level) by clinicians based on the patient's health and progress in skill. However, in developing countries, like India with increasing healthcare costs for availing specialized services, patients are often discharged sooner than required from healthcare units following stroke. Additionally, the situation becomes critical with limited availability of trained healthcare resources. Thus design of intelligent home-based technology-assisted individualized rehabilitation platform with real-time feedback with monitored skill progress is essential. In our present research, we have designed a Virtual Reality (VR) based haptic-enabled Physiologically Aided (PA) Rehabilitation System for patients with upper limb movement disorders. Additionally, we have made a comparative analysis of our PA system with Performance Sensitive (PS) system while offering tasks of varying difficulty levels along with audio-visual feedback. We have designed a Usability Study as proof-of-concept application where we have focused on the patient's shoulder abduction and adduction exercise. The preliminary results of our study are promising. This shows that our system can be a step towards designing a VR-based technology-assisted rehabilitation platform for stroke patients with a potential to address at least some of the issues associated with upper limb movement disorders.
Maturation of Binocular Pattern Visual Evoked Potentials in Normal Full-Term and Preterm Infants from 1 to 6 Months of Age

The purpose of this study was to evaluate the visual development of preterm infants from 1 to 6 mo of age, using the pattern visual evoked potentials (VEP) in response to three check sizes: 60, 30, and 15 min of arc. Pattern VEP were recorded in 24 full-term and 24 preterm infants (26–36 wk of gestation). The results showed a rapid visual maturation between 1 and 3 mo, followed by a slower progression over the next 3 mo, in both groups. The implicit time of the P100 wave of the pattern VEP was also found to shorten with increasing check sizes. The maturation of pattern VEP in preterm infants was shown to be related to their gestational (or corrected) age rather than their postnatal age. The pattern VEP obtained in response to a 60-min check size in preterm infants aged between 1.5 and 2.5 mo (corrected age) showed a tendency for a faster maturation than those of full-term infants. Our results suggest that within the first 6 mo of age, pattern VEP response is useful to monitor visual development in full-term infants as well as in preterm infants using corrected age.
Autologous bone marrow stem cells to treat acute myocardial infarction: a systematic review.

AIMS To provide systematic assessment of the safety and efficacy of autologous bone marrow-derived stem cell (BMSC) transplantation in acute myocardial infarction (AMI) based on clinical evidence. METHODS AND RESULTS The search strategy included MEDLINE, EMBASE, the Cochrane Library, and Current Controlled Trials Register through to August 2007 for randomized controlled trials of BMSC treatment for AMI. Thirteen trials (14 comparisons) with a total of 811 participants were included. Data were analysed using a random effects model. Overall, stem cell therapy improved left ventricular ejection fraction (LVEF) by 2.99% [95% confidence interval (CI), 1.26-4.72%, P = 0.0007], significantly reduced left ventricular end-systolic volume (LVESV) by 4.74 mL (95% CI, -7.84 to -1.64 mL, P = 0.003), and myocardial lesion area by 3.51% (95% CI, -5.91 to -1.11%, P = 0.004) compared with controls. Subgroup analysis revealed that there was statistical significant difference in LEVF in favour of BMSCs when cells were infused within 7 days following AMI and when the BMSC dose administered was higher than 10(8) BMSCs. In addition, there were trends in favour of benefit for most clinical outcomes examined, although it should be acknowledged that the 95%CI included no significant difference. CONCLUSION Stem cell treatment for AMI still holds promise. Clinically, these data suggest that improvement over conventional therapy can be achieved. Further, adequately powered trials using optimal dosing, longer term outcome assessments, more reliable, and more patient-centred outcomes are required.
Bulk versus boundary dynamics in anti-de Sitter space-time

We investigate the details of the bulk-boundary correspondence in Lorentzian signature anti-de Sitter space. Operators in the boundary theory couple to sources identified with the boundary values of non-normalizable bulk modes. Such modes do not fluctuate and provide classical backgrounds on which bulk excitations propagate. Normalizable modes in the bulk arise as a set of saddlepoints of the action for a fixed boundary condition. They fluctuate and describe the Hilbert space of physical states. We provide an explicit, complete set of both types of modes for free scalar fields in global and Poincar\'e coordinates. For $\ads{3}$, the normalizable and non-normalizable modes originate in the possible representations of the isometry group $\SL_L\times\SL_R$ for a field of given mass. We discuss the group properties of mode solutions in both global and Poincar\'e coordinates and their relation to different expansions of operators on the cylinder and on the plane. Finally, we discuss the extent to which the boundary theory is a useful description of the bulk spacetime.
A Bergman kernel proof of the Kawamata subadjunction theorem

The main purpose of the following article is to give a proof of Y. Kawamata's celebrated subadjunction theorem in the spirit of our previous work on Bergman kernels. We will use two main ingredients : an $\displaystyle L^{2\over m}$--extension theorem of Ohsawa-Takegoshi type (which is also a new result) and a more complete version of our former results.
Circumlocution in diagnostic medical queries

Circumlocution is when many words are used to describe what could be said with fewer, e.g., "a machine that takes moisture out of the air" instead of "dehumidifier. " Web search is a perfect backdrop for circumlocution where people struggle to name what they seek. In some domains, not knowing the correct term can have a significant impact on the search results that are retrieved. We study the medical domain, where professional medical terms are not commonly known and where the consequence of not knowing the correct term can impact the accuracy of surfaced information, as well as escalation of anxiety, and ultimately the medical care sought. Given a free-form colloquial health search query, our objective is to find the underlying professional medical term. The problem is complicated by the fact that people issue quite varied queries to describe what they have. Machine-learning algorithms can be brought to bear on the problem, but there are two key complexities: creating high-quality training data and identifying predictive features. To our knowledge, no prior work has been able to crack this important problem due to the lack of training data. We give novel solutions and demonstrate their efficacy via extensive experiments, greatly improving over the prior art.
