May I continue or should I stop? the effects of regulatory focus and message framings on video game playersâ self-control
Two types of motivations exist in terms of regulatory focus: a promotion orientation concerned with advancement and achievement and a prevention orientation concerned with safety and security. The central premise of this research is that promotion-focused and prevention-focused players differ in their sensitivity to message frames and therefore respond with different levels of self-control. This study adopted a 2 (message frames: positive vs. negative) Ă 2 (regulatory focus: promotion vs. prevention) between-subjects design; the results confirmed the hypotheses that, for promotion-focused players, negative messages are significantly effective in preventing them from becoming addicted to the games; meanwhile, for prevention-focused players, positive messages significantly influenced players, leading them to become addicted. Hence, video gamesâ negative and addiction-related messages should be enhanced whereas positive messages should be cautiously released.Regulatory focus, regulatory fit, message frames, self-control, video game
Buyer success and failure in bargaining and its consequences
This study aims to investigate the process of buyersâ subsequent attitudes and subsequent actions and their relationships depended on the bargaining outcomes. Depth interviews were employed in order to explore the success, the failure, and the consequent actions in dyadic bargaining under the condition of one buyer and one seller. Ten international respondents were invited to be interviewed. Approximately one hour of each interview is taken, while English is the medium of the interviews. After the interviews, respondents were given five USD as an incentive. The results show that successful bargainers tended to be younger people and easterner, compared to unsuccessful bargainers who tended to be older people and westerner. When buying product in computer and vehicle category, it might provide higher chance in getting the discount, while buying product in garment category gave the partial tendency to win the bargain. Since garment seems to have fewer profit margins when compared to the other category like computer or vehicle, it thus is obligatory for the seller to avoid discounting this kind of product. During the interviews, author found that confident interviewees shared their successful bargaining experiences; whereas, interviewees with very calm and quiet attitude seemed to express about their unsuccessful bargaining stories. This research also provides insights of buyer as bargainer profoundly. It therefore helps the seller, especially in computer, garment, and vehicle industry, knows how to balance mutual-interest and maintain the strong relationship with customer

A novel mutation in the WFS1 gene identified in a Taiwanese family with low-frequency hearing impairment
<p>Abstract</p> <p>Background</p> <p>Wolfram syndrome gene 1 (<it>WFS1</it>) accounts for most of the familial nonsyndromic low-frequency sensorineural hearing loss (LFSNHL) which is characterized by sensorineural hearing losses equal to and below 2000 Hz. The current study aimed to contribute to our understanding of the molecular basis of LFSNHL in an affected Taiwanese family.</p> <p>Methods</p> <p>The Taiwanese family with LFSNHL was phenotypically characterized using audiologic examination and pedigree analysis. Genetic characterization was performed by direct sequencing of <it>WFS1 </it>and mutation analysis.</p> <p>Results</p> <p>Pure tone audiometry confirmed that the family members affected with LFSNHL had a bilateral sensorineural hearing loss equal to or below 2000 Hz. The hearing loss threshold of the affected members showed no progression, a characteristic that was consistent with a mutation in the <it>WFS1 </it>gene located in the DFNA6/14/38 locus. Pedigree analysis showed a hereditarily autosomal dominant pattern characterized by a full penetrance. Among several polymorphisms, a missense mutation Y669H (2005T>C) in exon 8 of <it>WFS1 </it>was identified in members of a Taiwanese family diagnosed with LFSNHL but not in any of the control subjects.</p> <p>Conclusion</p> <p>We discovered a novel heterozygous missense mutation in exon 8 of <it>WFS1 </it>(i.e., Y669H) which is likely responsible for the LFSNHL phenotype in this particular Taiwanese family.</p
Detection of Baryon Acoustic Oscillation Features in the Large-Scale 3-Point Correlation Function of SDSS BOSS DR12 CMASS Galaxies
We present the large-scale 3-point correlation function (3PCF) of the SDSS
DR12 CMASS sample of Luminous Red Galaxies, the largest-ever sample
used for a 3PCF or bispectrum measurement. We make the first high-significance
() detection of Baryon Acoustic Oscillations (BAO) in the 3PCF.
Using these acoustic features in the 3PCF as a standard ruler, we measure the
distance to to precision (statistical plus systematic). We
find for our
fiducial cosmology (consistent with Planck 2015) and bias model. This
measurement extends the use of the BAO technique from the 2-point correlation
function (2PCF) and power spectrum to the 3PCF and opens an avenue for deriving
additional cosmological distance information from future large-scale structure
redshift surveys such as DESI. Our measured distance scale from the 3PCF is
fairly independent from that derived from the pre-reconstruction 2PCF and is
equivalent to increasing the length of BOSS by roughly 10\%; reconstruction
appears to lower the independence of the distance measurements. Fitting a model
including tidal tensor bias yields a moderate significance (
detection of this bias with a value in agreement with the prediction from local
Lagrangian biasing.Comment: 15 pages, 7 figures, submitted MNRA
Strong and broadly tunable plasmon resonances in thick films of aligned carbon nanotubes
Low-dimensional plasmonic materials can function as high quality terahertz
and infrared antennas at deep subwavelength scales. Despite these antennas'
strong coupling to electromagnetic fields, there is a pressing need to further
strengthen their absorption. We address this problem by fabricating thick films
of aligned, uniformly sized carbon nanotubes and showing that their plasmon
resonances are strong, narrow, and broadly tunable. With thicknesses ranging
from 25 to 250 nm, our films exhibit peak attenuation reaching 70%, quality
factors reaching 9, and electrostatically tunable peak frequencies by a factor
of 2.3x. Excellent nanotube alignment leads to the attenuation being 99%
linearly polarized along the nanotube axis. Increasing the film thickness
blueshifts the plasmon resonators down to peak wavelengths as low as 1.4
micrometers, promoting them to a new near-infrared regime in which they can
both overlap the S11 nanotube exciton energy and access the technologically
important infrared telecom band.Comment: 19 pages, 5 figures, main text followed by supporting informatio
The clustering of galaxies in the completed SDSS-III Baryon Oscillation Spectroscopic Survey: tomographic BAO analysis of DR12 combined sample in configuration space
We perform a tomographic baryon acoustic oscillations analysis using the
two-point galaxy correlation function measured from the combined sample of BOSS
DR12, which covers the redshift range of . Splitting the sample
into multiple overlapping redshift slices to extract the redshift information
of galaxy clustering, we obtain a measurement of and at
nine effective redshifts with the full covariance matrix calibrated using
MultiDark-Patchy mock catalogues. Using the reconstructed galaxy catalogues, we
obtain the precision of for and for
. To quantify the gain from the tomographic information, we compare
the constraints on the cosmological parameters using our 9-bin BAO
measurements, the consensus 3-bin BAO and RSD measurements at three effective
redshifts in \citet{Alam2016}, and the non-tomographic (1-bin) BAO measurement
at a single effective redshift. Comparing the 9-bin with 1-bin constraint
result, it can improve the dark energy Figure of Merit by a factor of 1.24 for
the Chevallier-Polarski-Linder parametrisation for equation of state parameter
. The errors of and from 9-bin constraints are slightly
improved when compared to the 3-bin constraint result.Comment: 14 pages, 21 figures, 7 Tables. Submitted to MNRA
The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: single-probe measurements from CMASS anisotropic galaxy clustering
With the largest spectroscopic galaxy survey volume drawn from the SDSS-III
Baryon Oscillation Spectroscopic Survey (BOSS), we can extract cosmological
constraints from the measurements of redshift and geometric distortions at
quasi-linear scales (e.g. above 50 Mpc). We analyze the broad-range
shape of the monopole and quadrupole correlation functions of the BOSS Data
Release 12 (DR12) CMASS galaxy sample, at the effective redshift , to
obtain constraints on the Hubble expansion rate , the angular-diameter
distance , the normalized growth rate , and the
physical matter density . We obtain robust measurements by
including a polynomial as the model for the systematic errors, and find it
works very well against the systematic effects, e.g., ones induced by stars and
seeing. We provide accurate measurements ,

where is the comoving sound horizon at the drag epoch and
Mpc is the sound scale of the fiducial cosmology used in
this study. The parameters which are not well constrained by our galaxy
clustering analysis are marginalized over with wide flat priors. Since no
priors from other data sets, e.g., cosmic microwave background (CMB), are
adopted and no dark energy models are assumed, our results from BOSS CMASS
galaxy clustering alone may be combined with other data sets, i.e., CMB, SNe,
lensing or other galaxy clustering data to constrain the parameters of a given
cosmological model. The uncertainty on the dark energy equation of state
parameter, , from CMB+CMASS is about 8 per cent. The uncertainty on the
curvature fraction, , is 0.3 per cent. We do not find deviation from
flat CDM.Comment: 15 pages, 11 figures. The latest version matches and the accepted
version by MNRAS. A bug in the first version has been identified and fixed in
the new version. We have redone the analysis with newest data (BOSS DR12
