When the barking stopped: Censorship, self-censorship and spin in Fiji
Authors: Hooper Robert A. 
Published: March 2017

After four military coups in 20 years, Fiji is poised to return to democracy in elections promised for 2014. An emergency decree placing censors in newsrooms was lifted in January 2012, but with domestic media gagged by lawsuits and Fiji Television threatened with closure for covering opposition figures, a pervasive climate of self-censorship imposed by government decrees is enforced by a government-appointed judiciary. As elections draw closer, the illusion of press freedom is framed by highly paid American ‘spin doctors’ from a prominent Washington DC public relations and lobbying firm. Paralysis in the newsroom is reflected at Fiji’s premier University of the South Pacific, once a leader in journalism education. The author taught television journalism at the university and trained reporters for Fiji TV in the 1990s, but returned to find Fiji’s media and higher education in a crisis reflecting the decline of Western influence in the Pacific. Student grievances over harassment and expulsion in retaliation for independent reporting echo the deceit and dysfunction unfolding on the national stage. As traditional allies Australia, New Zealand, United Kingdom and the United States anguish over sanctions, unprecedented visits to the Fijian government by Russian Foreign Minister Sergei Lavrov and incoming Chinese Premier Xi Jinping portend diplomatic rivalry and raise the stakes for a fragile Pacific nation.
Foreign and travel journalism on West Papua: The case of the Swedish press
Authors: Petersson Thomas 
Published: March 2017

This article analyses the characteristics of a considerable part of the foreign and travel journalism on West Papua that was published in Swedish press during the period 1959-2009. The analysed material comprises press items, articles, and reports on West Papua published in 27 different Swedish newspapers and periodicals. The comprehensive frame identified in the material is West Papua viewed as a primitive country. Four frames, characteristic of this general frame, are found in the foreign and travel journalism: 1) the primitive Others as dangerous and destructive; 2) the primitive Others as victims; 3) the primitive Others as admirable; and 4) the primitive Others as timeless and unchangeable. In the foreign and news material, a clear élite and big power perspective is apparent, which has been fundamental for when the conflict in West Papua is brought up on the journalistic agenda, and when it is not. A power fortifying integration between the frame of West Papua as a primitive country, and the élite and big power perspective exist in the material that during the entire time period covered by this investigation, has resulted in the Papuans being made invisible, and/or maintaining the Papuans and the conflict in West Papua as something odd, not holding a high value.
REVIEW: Meticulous study of early colonial infanticide
Authors: McGregor Judy 
Published: March 2017

Every once in a while an academic researcher will privately concede they would like to have written the book they have reviewed. Count me in that category. Nicola Goc’s examination of news narratives of infanticide from 1822-1922 in Britain and Australia reveals painstaking scholarship. It yields insights into the primacy of crime news, the ideology of infanticide news discourse, the privileging of medical and legal voices in courtroom reportage, and the personification of infanticide women as maternal deviants, mad women or as celebrity subjects of newspaper campaigning.

OBJECTIVEThe operative management of patients with adult spinal deformity (ASD) has a high complication rate and it remains unknown whether baseline patient characteristics and surgical variables can predict early complications (intraoperative and perioperative [within 6 weeks]). The development of an accurate preoperative predictive model can aid in patient counseling, shared decision making, and improved surgical planning. The purpose of this study was to develop a model based on baseline demographic, radiographic, and surgical factors that can predict if patients will sustain an intraoperative or perioperative major complication.METHODSThis study was a retrospective analysis of a prospective, multicenter ASD database. The inclusion criteria were age ≥ 18 years and the presence of ASD. In total, 45 variables were used in the initial training of the model including demographic data, comorbidities, modifiable surgical variables, baseline health-related quality of life, and coronal and sagittal radiographic parameters. Patients were grouped as either having at least 1 major intraoperative or perioperative complication (COMP group) or not (NOCOMP group). An ensemble of decision trees was constructed utilizing the C5.0 algorithm with 5 different bootstrapped models. Internal validation was accomplished via a 70/30 data split for training and testing each model, respectively. Overall accuracy, the area under the receiver operating characteristic (AUROC) curve, and predictor importance were calculated.RESULTSFive hundred fifty-seven patients were included: 409 (73.4%) in the NOCOMP group, and 148 (26.6%) in the COMP group. The overall model accuracy was 87.6% correct with an AUROC curve of 0.89 indicating a very good model fit. Twenty variables were determined to be the top predictors (importance ≥ 0.90 as determined by the model) and included (in decreasing importance): age, leg pain, Oswestry Disability Index, number of decompression levels, number of interbody fusion levels, Physical Component Summary of the SF-36, Scoliosis Research Society (SRS)–Schwab coronal curve type, Charlson Comorbidity Index, SRS activity, T-1 pelvic angle, American Society of Anesthesiologists grade, presence of osteoporosis, pelvic tilt, sagittal vertical axis, primary versus revision surgery, SRS pain, SRS total, use of bone morphogenetic protein, use of iliac crest graft, and pelvic incidence–lumbar lordosis mismatch.CONCLUSIONSA successful model (87% accuracy, 0.89 AUROC curve) was built predicting major intraoperative or perioperative complications following ASD surgery. This model can provide the foundation toward improved education and point-of-care decision making for patients undergoing ASD surgery.
High-frequency Oscillations in Small Magnetic Elements Observed with Sunrise/SuFI

Published: March 2017

Abstract
We characterize waves in small magnetic elements and investigate their propagation in the lower solar atmosphere from observations at high spatial and temporal resolution. We use the wavelet transform to analyze oscillations of both horizontal displacement and intensity in magnetic bright points found in the 300 nm and the Ca ii H 396.8 nm passbands of the filter imager on board the Sunrise balloon-borne solar observatory. Phase differences between the oscillations at the two atmospheric layers corresponding to the two passbands reveal upward propagating waves at high frequencies (up to 30 mHz). Weak signatures of standing as well as downward propagating waves are also obtained. Both compressible and incompressible (kink) waves are found in the small-scale magnetic features. The two types of waves have different, though overlapping, period distributions. Two independent estimates give a height difference of approximately 450 ± 100 km between the two atmospheric layers sampled by the employed spectral bands. This value, together with the determined short travel times of the transverse and longitudinal waves provide us with phase speeds of 29 ± 2 km s−1 and 31 ± 2 km s−1, respectively. We speculate that these phase speeds may not reflect the true propagation speeds of the waves. Thus, effects such as the refraction of fast longitudinal waves may contribute to an overestimate of the phase speed.

Abstract
A dense forest of slender bright fibrils near a small solar active region is seen in high-quality narrowband Ca ii H images from the SuFI instrument onboard the Sunrise balloon-borne solar observatory. The orientation of these slender Ca ii H fibrils (SCF) overlaps with the magnetic field configuration in the low solar chromosphere derived by magnetostatic extrapolation of the photospheric field observed with Sunrise/IMaX and SDO/HMI. In addition, many observed SCFs are qualitatively aligned with small-scale loops computed from a novel inversion approach based on best-fit numerical MHD simulation. Such loops are organized in canopy-like arches over quiet areas that differ in height depending on the field strength near their roots.
Brightness of Solar Magnetic Elements As a Function of Magnetic Flux at High Spatial Resolution
Authors: Kahil F. , Riethmüller T. L. , Solanki S. K. 
Published: March 2017

Abstract
We investigate the relationship between the photospheric magnetic field of small-scale magnetic elements in the quiet-Sun (QS) at disk center and the brightness at 214, 300, 313, 388, 397, and 525.02 nm. To this end, we analyzed spectropolarimetric and imaging time series acquired simultaneously by the Imaging Magnetograph eXperiment magnetograph and the SuFI filter imager on board the balloon-borne observatory

during its first science flight in 2009, with high spatial and temporal resolution. We find a clear dependence of the contrast in the near ultraviolet and the visible on the line-of-sight component of the magnetic field, B
LOS, which is best described by a logarithmic model. This function effectively represents the relationship between the Ca ii H-line emission and B
LOS and works better than the power-law fit adopted by previous studies. This, along with the high contrast reached at these wavelengths, will help with determining the contribution of small-scale elements in the QS to the irradiance changes for wavelengths below 388 nm. At all wavelengths, including the continuum at 525.40 nm, the intensity contrast does not decrease with increasing B
LOS. This result also strongly supports the fact that

has resolved small strong magnetic field elements in the internetwork, resulting in constant contrasts for large magnetic fields in our continuum contrast at 525.40 nm versus the B
LOS scatterplot, unlike the turnover obtained in previous observational studies. This turnover is due to the intermixing of the bright magnetic features with the dark intergranular lanes surrounding them.

Abstract
Spectropolarimetric observations from Sunrise/IMaX, obtained in 2013 June, are used for a statistical analysis to determine the physical properties of moving magnetic features (MMFs) observed near a pore. MMFs of the same and opposite polarity, with respect to the pore, are found to stream from its border at an average speed of 1.3 km s−1 and 1.2 km s−1, respectively, with mainly same-polarity MMFs found further away from the pore. MMFs of both polarities are found to harbor rather weak, inclined magnetic fields. Opposite-polarity MMFs are blueshifted, whereas same-polarity MMFs do not show any preference for up- or downflows. Most of the MMFs are found to be of sub-arcsecond size and carry a mean flux of ∼1.2 × 1017 Mx.

Abstract
We study the dynamics and topology of an emerging magnetic flux concentration using high spatial resolution spectropolarimetric data acquired with the Imaging Magnetograph eXperiment on board the sunrise balloon-borne solar observatory. We obtain the full vector magnetic field and the line of sight (LOS) velocity through inversions of the Fe i line at 525.02 nm with the SPINOR code. The derived vector magnetic field is used to trace magnetic field lines. Two magnetic flux concentrations with different polarities and LOS velocities are found to be connected by a group of arch-shaped magnetic field lines. The positive polarity footpoint is weaker (1100 G) and displays an upflow, while the negative polarity footpoint is stronger (2200 G) and shows a downflow. This configuration is naturally interpreted as a siphon flow along an arched magnetic flux tube.
