- A major goal of the Atacama Large Millimeter/submillimeter Array (ALMA) is to make accurate images with resolutions of tens of milliarcseconds, which at submillimeter (submm) wavelengths requires baselines up to similar to 15 km. To develop and test this capability, a Long Baseline Campaign (LBC) was carried out from 2014 September to late November, culminating in end-to-end observations, calibrations, and imaging of selected Science Verification (SV) targets. This paper presents an overview of the campaign and its main results, including an investigation of the short-term coherence properties and systematic phase errors over the long baselines at the ALMA site, a summary of the SV targets and observations, and recommendations for science observing strategies at long baselines. Deep ALMA images of the quasar 3C 138 at 97 and 241 GHz are also compared to VLA 43 GHz results, demonstrating an agreement at a level of a few percent. As a result of the extensive program of LBC testing, the highly successful SV imaging at long baselines achieved angular resolutions as fine as 19 mas at similar to 350 GHz. Observing with ALMA on baselines of up to 15 km is now possible, and opens up new parameter space for submm astronomy.

An update to the surface ocean CO2 atlas (SOCAT version 2)

- The Surface Ocean CO2 Atlas (SOCAT), an activity of the international marine carbon research community, provides access to synthesis and gridded fCO2 (fugacity of carbon dioxide) products for the surface oceans. Version 2 of SOCAT is an update of the previous release (version 1) with more data (increased from 6.3 million to 10.1 million surface water fCO 2 values) and extended data coverage (from 1968-2007 to 1968-2011). The quality control criteria, while identical in both versions, have been applied more strictly in version 2 than in version 1. The SOCAT website (http://www.socat.info/) has links to quality control comments, metadata, individual data set files, and synthesis and gridded data products. Interactive online tools allow visitors to explore the richness of the data. Applications of SOCAT include process studies, quantification of the ocean carbon sink and its spatial, seasonal, year-to-year and longerterm variation, as well as initialisation or validation of ocean carbon models and coupled climate-carbon models. © Author(s) 2014.

- Introduction: Overt and covert control are novel constructs representing two different parental feeding practices with regard to the child's ability to detect them. Preliminary research indicates that covert control is linked to a healthier diet and lower child weight status. In this study,we report the first psychometric validation of the original measures of overt and covert control outside the UK in a large sample of parents of preschoolers.Methods: Based on records from the population register, all mothers of 4-year-olds (n = 3007) from the third largest city in Sweden,Malmö, were contacted by mail. Out of those, 876 returned the measures of overt and covert control together with a background questionnaire and the Child Feeding Questionnaire (CFQ). Test–retest data were obtained from 64% (n = 563) of these mothers. The mean age of the mothers was 35.6 years; their mean BMI was 24.1, 31.5% were overweight or obese. The children were on average 4.5 years old; 48% were girls, 12.8% were overweight or obese.Results: While the fit for the original 9-item 2-factor model was poor, shorter 8- and 6-item versions were supported by confirmatory factor analysis (CFI N 0.95, RMSEA b 0.05). Internal and test–retest reliability of the shorter version was good (ICC= 0.65–0.71). Results also suggest that the factor structure and loadings were invariant (i.e., did not significantly differ) over time and between child sexes. Both overt and covert control factors were moderately correlated with CFQ monitoring. Overt control was also moderately related to CFQ pressure and weakly correlated with CFQ restriction. Covert control, on the other hand, was moderately related to restriction and not related with pressure. Correlations of both factors with child and parent BMI were very small.Conclusion: We found good psychometric properties of the revised versions of the overt and control behaviors in a multiethnic sample of mothers from Sweden. Future studies need to establish causal associations between overt and covert control and the obesity related outcomes.
