Predictors of Playing Augmented Reality Mobile Games While Walking Based on the Theory of Planned Behavior: Web-Based Survey
Authors: Koh Hyeseung Elizabeth , Oh Jeeyun , Mackert Michael 
Published: December 2017

Background
There has been a sharp increase in the number of pedestrians injured while using a mobile phone, but little research has been conducted to explain how and why people use mobile devices while walking. Therefore, we conducted a survey study to explicate the motivations of mobile phone use while walking

Objective
The purpose of this study was to identify the critical predictors of behavioral intention to play a popular mobile game, Pokemon Go, while walking, based on the theory of planned behavior (TPB). In addition to the three components of TPB, automaticity, immersion, and enjoyment were added to the model. This study is a theory-based investigation that explores the underlying mechanisms of mobile phone use while walking focusing on a mobile game behavior.

Methods
Participants were recruited from a university (study 1; N=262) and Amazon Mechanical Turk (MTurk) (study 2; N=197) in the United States. Participants completed a Web-based questionnaire, which included measures of attitude, subjective norms, perceived behavioral control (PBC), automaticity, immersion, and enjoyment. Participants also answered questions regarding demographic items.

Results
Hierarchical regression analyses were conducted to examine hypotheses. The model we tested explained about 41% (study 1) and 63% (study 2) of people’s intention to play Pokemon Go while walking. The following 3 TPB variables were significant predictors of intention to play Pokemon Go while walking in study 1 and study 2: attitude (P<.001), subjective norms (P<.001), and PBC (P=.007 in study 1; P<.001 in study 2). Automaticity tendency (P<.001), immersion (P=.02), and enjoyment (P=.04) were significant predictors in study 1, whereas enjoyment was the only significant predictor in study 2 (P=.01).

Conclusions
Findings from this study demonstrated the utility of TPB in predicting a new behavioral domain—mobile use while walking. To sum up, younger users who are habitual, impulsive, and less immersed players are more likely to intend to play a mobile game while walking.
Glamourin markkinamiehet: kiiltopaperilehdet Venäjällä
Authors: Pietiläinen Jukka 
Published: December 2017

Ensimmäiset kiiltopaperilehdet (eng.: glossy magazines, ven.: gljantsevyje žurnaly) ilmestyivät Venäjälle vasta 1990-luvulla. Ulkomaisten brändien Cosmopolitan (1994) ja Elle (1996) myötä perinteiset venäläiset naistenlehdet alkoivat muuttua sisällöltäänkin kiiltopaperimaiseksi. Tämän myötä (tai tämän vuoksi) venäläiset naistenlehdet alkoivat menettää myös lukijoitaan. Hyvin nopeasti käsite ”kiiltopaperilehti” sai oman merkityksensä: se ei viitannut vain lehtien painopaperiin vaan myös niiden sisältöön. Kiiltopaperilehdet markkinoivat kallista elämäntapaa sekä unelmia kauneudesta, terveydestä, vapaudesta, rikkaudesta ja mielihyvästä. Rinnakkainen käsite ”glamour-kiiltopaperilehdet” (glamurnyje gljantsevyje žurnaly) korostaa vielä edellistä enemmän lehtien ideologista roolia kulutusyhteiskunnan ja kalliiden tavaroiden kuluttamisen promoottorina. Glamour-lehden venäjänkielinen painos alkoi ilmestyä vuonna 2004. Kansainvälinen venäjänkielen opettajien liitto valitsi sanan glamur venäjän kielen vuoden sanaksi vuonna 2007. Suuri osa kiiltopaperilehdistä perustuu länsimaisiin formaatteihin ja useiden lehtien nimi on kannessa latinalaisin kirjaimin. Kiiltopaperilehdet muokkaavat venäläisen keskiluokan kulutuskäyttäytymistä ja yhteiskunnallisia asenteita markkinoidessa modernia yhteiskuntaa ja sen elämäntapaa. Siten ne toimivat samaan tapaa uudenlaisen yhteiskunnan markkinoijina kuin sanomalehdet joskus aikaisemmin.
Pohjoisen ydinmylly<br>Fennovoima kolmessa suomalaisessa sanomalehdessä 2007–2013
Authors: Vehkalahti Pertti 
Published: December 2017

Artikkelissa tutkitaan lehtikirjoittelua Fennovoiman ydinvoimalahankkeesta. Aineistona ovat Helsingin Sanomissa, Kalevassa ja Raahen Seudussa julkaistut lehtijutut ja mielipidekirjoitukset vuosilta 2007–2013. Artikkelissa selvitetään, minkä verran eri ryhmät esiintyivät puhujina lehtien sivuilla. Lisäksi tarkastellaan, mistä aiheista aineistossa puhuttiin ja millaisten ydinvoima-argumenttien yhteydessä eri puhujat esiintyivät. Tutkimus perustuu aineiston määrälliseen luokitteluun ja siitä tehtyyn analyysiin. Tulokset osoittavat, että Fennovoima ja muu talouselämä saavat paljon tilaa lehdissä. Ydinvoimamyönteisten juttujen lisäksi ne esiintyvät usein asiaan neutraalisti suhtautuvissa kirjoituksissa. Valtion ja kuntien edustajat esiintyvät myös paljon. Ydinvoimaa vastustavat järjestöt saavat näkyvyyttä alue- ja paikallislehdessä, mutta valtakunnanjulkisuuteen ne eivät juuri ulotu.
Osteochondromyxoma of the nasal cavity: case report and review of the literature
Authors: Waissbluth Sofia , Winter Matias , Dreyse Ximena , Solar Antonieta , Castro Marcelo , Rosenblut Andrés 
Published: December 2017

Background:
Osteochondromyxoma is an extremely rare benign tumor. Few cases have been described in the literature. Patients with Carney complex may present with this tumor.

Case Presentation:
We report a case of a nasal osteochondromyxoma in a 21-year-old female patient who presented with progressive nasal congestion, anosmia, and episodes of self-limiting epistaxis. Magnetic resonance imaging and computerized axial tomography scans were performed which demonstrated a large tumor occupying the nasal cavity. Endoscopic sinus surgery was performed resulting in complete resection of the tumor. No recurrence has been observed at 24 months following endoscopic sinus surgery. The patient has also recovered olfaction.

Conclusion:
Although osteochondromyxomas are extremely rare, it should be considered as a differential diagnosis for nasal tumors and surgical resection should be completed. A multidisciplinary assessment is recommended as it is a major criterion for the diagnosis of Carney complex.

Published: December 2017

The aims of this study was to improve the social emotional early childhood through the traditional game. This research was conducted on the children of group B TK Pradnyandari III Kerobokan in the academic year 2016 / 2017. This research used Classroom Action Research design with observation method. The subjects of this study were 22 children ofÂ group B1 TK Pradnyandari III Kerobokan consisting of 11 sons and 11 daughters. The object of research is the application of traditional children's games to increase social emotional early childhood. The results og this research as in Cycle I, 14 children (63.64%) reached the completeness learning mastery, 8 children (36.36%) had not reached. In Cycle II, 20 children (90,91%) reached the learning mastery, leaving only 2 children (9,09%) had not reached. The implementation of traditional games can enhance children's social emotional skill. Based on the research findings there was an improvement of 27.27% learning mastery of the children from Cycle I to Cycle II. This means that the application of traditional games can improve children's social emotional development. Traditional games can be piloted in other areas of development skill in early childhood education.

Abstract
Observations of rotational modulations of brown dwarfs and giant exoplanets allow the characterization of condensate cloud properties. As of now, rotational spectral modulations have only been seen in three L-type brown dwarfs. We report here the discovery of rotational spectral modulations in LP261-75B, an L6-type intermediate surface gravity companion to an M4.5 star. As a part of the Cloud Atlas Treasury program, we acquired time-resolved Wide Field Camera 3 grism spectroscopy (1.1–1.69 μm) of LP261-75B. We find gray spectral variations with the relative amplitude displaying only a weak wavelength dependence and no evidence for lower-amplitude modulations in the 1.4 μm water band than in the adjacent continuum. The likely rotational modulation period is 4.78 ± 0.95 hr, although the rotational phase is not well sampled. The minimum relative amplitude in the white light curve measured over the whole wavelength range is 2.41% ± 0.14%. We report an unusual light curve, which seems to have three peaks approximately evenly distributed in rotational phase. The spectral modulations suggests that the upper atmosphere cloud properties in LP261-75B are similar to two other mid-L dwarfs of typical infrared colors, but differ from that of the extremely red L-dwarf WISE0047.

Abstract
The Alice far-ultraviolet imaging spectrograph onboard Rosetta observed emissions from atomic and molecular species from within the coma of comet 67P/Churyumov–Gerasimenko during the entire escort phase of the mission from 2014 August to 2016 September. The initial observations showed that emissions of atomic hydrogen and oxygen close to the surface were produced by energetic electron impact dissociation of H2O. Following delivery of the lander, Philae, on 2014 November 12, the trajectory of Rosetta shifted to near-terminator orbits that allowed for these emissions to be observed against the shadowed nucleus that, together with the compositional heterogeneity, enabled us to identify unique spectral signatures of dissociative electron impact excitation of H2O, CO2, and O2. CO emissions were found to be due to both electron and photoexcitation processes. Thus, we are able, from far-ultraviolet spectroscopy, to qualitatively study the evolution of the primary molecular constituents of the gaseous coma from start to finish of the escort phase. Our results show asymmetric outgassing of H2O and CO2 about perihelion, H2O dominant before and CO2 dominant after, consistent with the results from both the in situ and other remote sensing instruments on Rosetta.
Star-forming Environments throughout the M101 Group
Authors: Watkins Aaron E. , Mihos J. Christopher , Harding Paul 
Published: December 2017

Abstract
We present a multiwavelength study of star formation within the nearby M101 Group, including new deep Hα imaging of M101 and its two companions. We perform a statistical analysis of the Hα-to-FUV flux ratios in H ii regions located in three different environments: M101's inner disk, M101's outer disk, and M101's lower-mass companion galaxy NGC 5474. We find that, once bulk radial trends in extinction are taken into account, both the median and scatter in F
Hα
/F
FUV in H ii regions are invariant across all of these environments. Also, using Starburst99 models, we are able to qualitatively reproduce the distributions of F
Hα
/F
FUV throughout these different environments using a standard Kroupa initial mass function (IMF); hence, we find no need to invoke truncations in the upper-mass end of the IMF to explain the young star-forming regions in the M101 Group even at extremely low surface density. This implies that star formation in low-density environments differs from star formation in high-density environments only by intensity and not by cloud-to-cloud physics.

Published: December 2017

Abstract
The second most significant detection of the Planck Sunyaev−Zel’dovich survey, PLCK G287.0+32.9 (z = 0.385), boasts two similarly bright radio relics and a radio halo. One radio relic is located

NW of the X-ray peak and the other

Mpc to the SE. This large difference suggests that a complex merging scenario is required. A key missing puzzle for the merging scenario reconstruction is the underlying dark matter distribution in high resolution. We present a joint Subaru Telescope and Hubble Space Telescope weak-lensing analysis of the cluster. Our analysis shows that the mass distribution features four significant substructures. Of the substructures, a primary cluster of mass

dominates the weak-lensing signal. This cluster is likely to be undergoing a merger with one (or more) subcluster whose mass is approximately a factor of 10 lower. One candidate is the subcluster of mass

located

to the SE. The location of this subcluster suggests that its interaction with the primary cluster could be the source of the NW radio relic. Another subcluster is detected

Mpc to the SE of the X-ray peak with mass

. This SE subcluster is in the vicinity of the SE radio relic and may have created the SE radio relic during a past merger with the primary cluster. The fourth subcluster,

, is NW of the X-ray peak and beyond the NW radio relic.
Cosmic Star Formation: A Simple Model of the SFRD(z)
Authors: Chiosi Cesare , Sciarratta Mauro , D’Onofrio Mauro , Chiosi Emanuela , Brotto Francesca , Michele Rosaria De , Politino Valeria 
Published: December 2017

Abstract
We investigate the evolution of the cosmic star formation rate density (SFRD) from redshift z = 20 to z = 0 and compare it with the observational one by Madau and Dickinson derived from recent compilations of ultraviolet (UV) and infrared (IR) data. The theoretical SFRD(z) and its evolution are obtained using a simple model that folds together the star formation histories of prototype galaxies that are designed to represent real objects of different morphological type along the Hubble sequence and the hierarchical growing of structures under the action of gravity from small perturbations to large-scale objects in Λ-CDM cosmogony, i.e., the number density of dark matter halos

. Although the overall model is very simple and easy to set up, it provides results that mimic results obtained from highly complex large-scale N-body simulations well. The simplicity of our approach allows us to test different assumptions for the star formation law in galaxies, the effects of energy feedback from stars to interstellar gas, the efficiency of galactic winds, and also the effect of

. The result of our analysis is that in the framework of the hierarchical assembly of galaxies, the so-called time-delayed star formation under plain assumptions mainly for the energy feedback and galactic winds can reproduce the observational SFRD(z).
Where Are LIGO’s Big Black Holes?
Authors: Fishbach Maya , Holz Daniel E. 
Published: December 2017

Abstract
In LIGO’s O1 and O2 observational runs, the detectors were sensitive to stellar-mass binary black hole (BBH) coalescences with component masses up to

, with binaries with primary masses above

representing ≳90% of the total accessible sensitive volume. Nonetheless, of the 5.9 detections (GW150914, LVT151012, GW151226, GW170104, GW170608, and GW170814) reported by LIGO-Virgo, the most massive binary detected was GW150914 with a primary component mass of

, far below the detection mass limit. Furthermore, there are theoretical arguments in favor of an upper mass gap, predicting an absence of black holes in the mass range

. We argue that the absence of detected binary systems with component masses heavier than

may be preliminary evidence for this upper mass gap. By allowing for the presence of a mass gap, we find weaker constraints on the shape of the underlying mass distribution of BBHs. We fit a power-law distribution with an upper mass cutoff to real and simulated BBH mass measurements, finding that the first 3.9 BBHs favor shallow power-law slopes

and an upper mass cutoff

. This inferred distribution is entirely consistent with the two recently reported detections, GW170608 and GW170814. We show that with ∼10 additional LIGO-Virgo BBH detections, fitting the BH mass distribution will provide strong evidence for an upper mass gap if one exists.

Abstract
The transient neutron star (NS) low-mass X-ray binary MAXI J0556−332 provides a rare opportunity to study NS crust heating and subsequent cooling for multiple outbursts of the same source. We examine MAXI, Swift, Chandra, and XMM-Newton data of MAXI J0556−332 obtained during and after three accretion outbursts of different durations and brightnesses. We report on new data obtained after outburst III. The source has been tracked up to ∼1800 days after the end of outburst I. Outburst I heated the crust strongly, but no significant reheating was observed during outburst II. Cooling from ∼333 eV to ∼146 eV was observed during the first ∼1200 days. Outburst III reheated the crust up to ∼167 eV, after which the crust cooled again to ∼131 eV in ∼350 days. We model the thermal evolution of the crust and find that this source required a different strength and depth of shallow heating during each of the three outbursts. The shallow heating released during outburst I was ∼17 MeV nucleon−1 and outburst III required ∼0.3 MeV nucleon−1. These cooling observations could not be explained without shallow heating. The shallow heating for outburst II was not well constrained and could vary from ∼0 to 2.2 MeV nucleon−1, i.e., this outburst could in principle be explained without invoking shallow heating. We discuss the nature of the shallow heating and why it may occur at different strengths and depths during different outbursts.
In Vivo Early Corneal Biomechanical Changes After Corneal Cross-linking in Patients With Progressive Keratoconus
Authors: Vinciguerra Riccardo , Romano Vito , Arbabi Esmaeil M. , Brunner Matthias , Willoughby Colin E. , Batterbury Mark , Kaye Stephen B. 
Published: December 2017

PURPOSE:
To report early corneal biomechanical changes after corneal cross-linking (CXL) in patients with keratoconus.

METHODS:
Thirty-four eyes of 34 patients undergoing CXL for progressive keratoconus were included in this prospective clinical study. Dynamic corneal response (DCR) parameters obtained with the Corvis ST (OCULUS Optikgeräte GmbH; Wetzlar, Germany) were assessed at baseline (day of CXL) and after 1 month of follow-up; conversely, corneal tomography with the Pentacam (OCULUS Optikgeräte GmbH) was assessed at baseline and at 1, 3, and 6 months after CXL.

RESULTS:

At the last follow-up visit (123.7 ± 69.6 days), all morphological parameters including steepest point (Kmax) and thinnest corneal thickness (ThCT) indicated stabilization of keratoconus (
P
> .05). Comparative analyses showed a rise of corneal stiffness demonstrated by a significant increase of Stiffness Parameter A1 (SP-A1) and Highest Concavity (SP-HC) and a significant decrease of Inverse Concave Radius (1/R) and Deformation Amplitude Ratio (DA Ratio) (
P
< .05). There was a significant correlation between the preoperative keratoconus characteristics (Kmax, Belin/Ambrósio final D value [BAD-D], and ThCT) and the DCR parameters (
P
< .05). Kmax and BAD-D showed a significant positive correlation with DA Ratio, Deflection Amplitude (DefA), and 1/R and a significant negative correlation with SPA1 and SP-HC. ThCT showed a significant positive correlation with SP-A1 and SP-HC and a significant negative correlation with DA Ratio, DefA, and 1/R.

CONCLUSIONS:
This study suggests that the new DCR parameters of the Corvis ST are able to detect early changes in biomechanics following CXL and those that are measurable before corneal shape modifications take place. Based on these results, the authors suggest the use of these metrics to assess the early efficacy of cross-linking.

Laboratory Evaluation of the Influence of Decentration and Pupil Size on the Optical Performance of a Monofocal, Bifocal, and Trifocal Intraocular Lens
Authors: Tandogan Tamer , Son Hyeck Soo , Choi Chul Young , Knorz Michael C. , Auffarth Gerd U. , Khoramnia Ramin 
Published: December 2017

PURPOSE:
To assess the influence of decentration and aperture size on the optical quality of different intraocular lenses (IOLs) of the same material, body design, and refractive power using standardized optical bench testing.

METHODS:
Using an optical bench set-up, an aspheric monofocal (CT ASPHINA 409M; Carl Zeiss Meditec, Jena, Germany), an aspheric diffractive bifocal (AT LISA 809M; Carl Zeiss Meditec), and an aspheric diffractive trifocal (AT LISA 839M; Carl Zeiss Meditec) intraocular lens (IOL) were evaluated, each with the same distance power, body design, and material. Modulation transfer function (MTF) values were measured at spatial frequencies of 50 lp/mm and aperture sizes of 3 and 4.5 mm. Each IOL was measured while centered, then decentered by 0.25, 0.5, 0.75, and 1 mm.

RESULTS:
MTF values for the monofocal IOL at far focus with 3- and 4.5-mm aperture size were 0.80/0.80 with maximum reduction to 0.77/0.73 for 1-mm decentration, respectively. Centered IOL MTFs of the bifocal and trifocal IOLs were lower for the far focus at 0.46/0.41 and 0.39/0.26, with reduction at 1-mm decentration to 0.35/0.25 and 0.25/0.18, respectively. Values for near focus of the bifocal and trifocal IOLs reduced from 0.27/0.31 and 0.19/0.18 to 0.2/0.21 and 0.12/0.13, respectively. The trifocal intermediate focus MTF reduced from 0.15/0.10 to 0.12/0.08. MTF values of all three lenses decreased significantly under all conditions with decentration of 0.5 to 0.75 mm.

CONCLUSIONS:
Monofocal lenses were least negatively affected by decentration, with mean optical quality reduction of less than 10% for 1-mm decentration at physiological pupil sizes. For diffractive bifocal and trifocal lenses, optical quality at all distances was significantly reduced if decentration exceeded 0.75 mm, with intermediate focus showing the least reduction.
