- The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since 2014 July. This paper describes the second data release from this phase, and the 14th from SDSS overall (making this Data Release Fourteen or DR14). This release makes the data taken by SDSS-IV in its first two years of operation (2014-2016 July) public. Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey; the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data-driven machine-learning algorithm known as "The Cannon"; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from the SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS web site (www.sdss.org) has been updated for this release and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020 and will be followed by SDSS-V.

- We describe the Sloan Digital Sky Survey IV (SDSS-IV), a project encompassing three major spectroscopic programs. The Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) is observing hundreds of thousands of Milky Way stars at high resolution and. high signal-to-noise ratios in the near-infrared. The Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey is obtaining spatially resolved spectroscopy for thousands of nearby galaxies (median z similar to 0.03). The extended Baryon Oscillation Spectroscopic Survey (eBOSS) is mapping the galaxy, quasar, and neutral gas distributions between z similar to 0.6 and 3.5 to constrain cosmology using baryon acoustic oscillations, redshift space distortions, and the shape of the power spectrum. Within eBOSS, we are conducting two major subprograms: the SPectroscopic IDentification of eROSITA Sources (SPIDERS), investigating X-ray AGNs. and galaxies in X-ray clusters, and the Time Domain Spectroscopic Survey (TDSS), obtaining spectra of variable sources. All programs use the 2.5 m Sloan Foundation Telescope at the. Apache Point Observatory; observations there began in Summer 2014. APOGEE-2 also operates a second near-infrared spectrograph at the 2.5 m du Pont Telescope at Las Campanas Observatory, with observations beginning in early 2017. Observations at both facilities are scheduled to continue through 2020. In keeping with previous SDSS policy, SDSS-IV provides regularly scheduled public data releases; the first one, Data Release 13, was made available in 2016 July.

- Objectives: To examine health-related quality of life (HRQoL) in young children with low language or congenital hearing loss and to explore the value of assessing HRQoL by concurrently administering 2 HRQoL instruments in populations of children.Methods: Data were from 2 Australian community-based studies: Language for Learning (children with typical and low language at age 4 years, n = 1012) and the Statewide Comparison of Outcomes study (children with hearing loss, n = 108). HRQoL was measured using the parent-reported Health Utilities Index Mark 3 (HUI3) and the Pediatrics Quality of Life Inventory 4.0 (PedsQL) generic core scale. Agreement between the HRQoL instruments was assessed using intraclass correlation and Bland-Altman plots.Results: Children with low language and with hearing loss had lower HRQoL than children with normal language; the worst HRQoL was experienced by children with both. The lower HRQoL was mainly due to impaired school functioning (PedsQL) and speech and cognition (HUI3). Children with hearing loss also had impaired physical and social functioning (PedsQL), vision, hearing, dexterity, and ambulation (HUI3). Correlations between instruments were poor to moderate, with low agreement.Conclusions: Children with low language and congenital hearing loss might benefit from interventions targeting overall health and well-being, not just their impairments. The HUI3 and PedsQL each seemed to provide unique information and thus may supplement each other in assessing HRQoL of young children, including those with low language or congenital hearing loss.

- AIM: To examine the relationship between mothers' health-related quality of life (HRQoL) and child behaviour problems at age 2 years. To investigate whether the relationship between maternal HRQoL and child behaviour problems is independent of maternal mental health.METHODS: Cross-sectional survey nested within a population-level, cluster randomised trial, which aims to prevent early child behaviour problems. One hundred and sixty mothers of 2-year-old children, in nine local government areas in Victoria, Australia. HRQoL was measured using the Assessment of Quality of Life 6D and child behaviour was measured using the child behaviour checklist (CBCL/1.5-5 years). Maternal mental health was measured using the Depression Anxiety Stress Scale. Data were collected at child age 2 years; demographic data were collected at child age 8 months.RESULTS: HRQoL was lower for mothers with children that had borderline/clinical behaviour problems compared to those with children without problems (mean difference -0.14, 95% confidence interval (CI): -0.16 to -0.12, P < 0.001). The finding did not markedly change when adjusting for household income, financial security, child gender, child temperament and intervention group status at child age 8 months (mean difference -0.12, 95% CI: -0.15 to -0.09, P < 0.001), but did attenuate when additionally adjusting for concurrent maternal mental health (mean difference -0.03, 95% CI: -0.05 to -0.02, P < 0.001).CONCLUSIONS: Child behaviour problems were associated with lower maternal HRQoL. Child behaviour problems prevention programmes could consider this association with maternal HRQoL and be designed to improve and report both mothers' and their child's health and wellbeing.

- BACKGROUND: Maternal shared reading practices predict emergent literacy, but fathers' contributions are less certain. We examined whether fathers' shared home reading activities at 2 years (1) predict language and emergent literacy at age 4 years, when controlling for maternal contributions; and (2) differentially benefit these outcomes in disadvantaged children.METHODS: Design: Two-parent families recruited from 5 relatively disadvantaged communities for the universal Let's Read literacy promotion population-based trial (ISRCTN 04602902) in Melbourne, Australia. Exposure, 2 years: Home reading practices via self-reported maternal and paternal StimQ-Toddler questionnaires, dichotomised at study median (high vs. low). Outcomes, 4 years: Receptive and expressive language (Clinical Evaluation of Language Fundamentals-4), emergent literacy (Sunderland Phonological Awareness Test-Revised).ANALYSES: Aim 1: Linear regression, adjusted for mothers' home reading, 2-year-old vocabulary and communication skills and family disadvantage. Aim 2: Interaction of disadvantage [yes vs. no] with high home reading by (a) fathers and (b) at least one parent.RESULTS: Data were available for 405 (62.3%) families. High father reading at 2 years (reference: low) predicted better expressive (mean difference 8.0, 95%CI 4.5 to 11.5) and receptive (mean difference 7.3, 95%CI 4.1 to 10.5) language at 4 years (both p<0.001) but not emergent literacy skills. Similar patterns were observed in families with at least one parent with high home reading. Father reading did not differentially benefit outcomes in disadvantaged children.CONCLUSION: Fathers' involvement in reading at 2 years predicted better language but not emergent literacy at 4 years, and did not protect against adverse effects of socioeconomic disadvantage.
