The SCUBA Local Universe Galaxy Survey [PDF]
The SCUBA local universe galaxy survey is the first systematic survey of the local universe at submillimetre wavelengths. We have observed ~200 galaxies from the IRAS bright galaxy catalogue and the CfA optical redshift survey.

Crafting Survey Research: A Systematic Process for Conducting Survey Research
Surveys represent flexible and powerful ways for practitioners to gain insights into customers and markets and for researchers to develop, test, and generalize theories. However, conducting effective survey research is challenging. Survey researchers must induce participation by “over-surveyed” respondents, choose appropriately from among numerous ...

Cochrane acute respiratory infections group's stakeholder engagement project identified systematic review priority areas [PDF]
Objective: Cochrane acute respiratory infections (ARIs) group conducts systematic reviews of the evidence for treatment and prevention of ARIs. We report the results of a prioritization project, aiming to identify highest priority systematic review ...

Cross-correlation Weak Lensing of SDSS galaxy Clusters II: Cluster Density Profiles and the Mass--Richness Relation [PDF]
We interpret and model the statistical weak lensing measurements around 130,000 groups and clusters of galaxies in the Sloan Digital Sky Survey presented by Sheldon et al. 2007 (Paper I).

The Carboniferous medullosalean pteridosperm Havlenaea praeovata (Němejc) Šimůnek
A study of Ettingshausen’s type material of Neuropteris coriacea stored in the Geologisches Bundesanstalt in Vienna has demonstrated that they are conspecific with Havlenaea praeovata (Němejc) Šimůnek & Cleal (Carboniferous medullosalean pteridosperm ...

Systematic Differences between Radio Astrometric Surveys [PDF]
AbstractA radio astronomical reference frame has been established from four interferometric position surveys of extragalactic objects. The resulting systematic differences between surveys were studied with different weighting schemes and averaged systematic corrections were derived.

The APM Galaxy Survey III: An Analysis of Systematic Errors in the Angular Correlation Function and Cosmological Implications [PDF]
We present measurements of the angular two-point galaxy correlation function, $w(theta)$, from the APM Galaxy Survey. The performance of various estimators of $w$ is assessed using simulated galaxy catalogues and analytic arguments.

Forward Global Photometric Calibration of the Dark Energy Survey [PDF]
Many scientific goals for the Dark Energy Survey (DES) require calibration of optical/NIR broadband $b = grizY$ photometry that is stable in time and uniform over the celestial sky to one percent or better.

Virtual Reality (VR) users typically either sit or stand/walk when using VR; however, the impact of this is little researched, and there is a lack of any broad or systematic analysis of how this difference in physical posture might affect user experience

The power spectrum of galaxies in the 2dF 100k redshift survey [PDF]
We compute the real-space power spectrum and the redshift-space distortions of galaxies in the 2dF 100k galaxy redshift survey using pseudo-Karhunen-Loeve eigenmodes and the stochastic bias formalism.
