Adopting or resisting 24-hour news logic on evening bulletins? the mediatization of UK television news 1991-2012
This study carries out a longitudinal content analysis of United Kingdom (UK) fixed time evening news bulletins between 1991 and 2012 (N = 2040) in order to systematically examine whether they have adapted their format for the rolling news age with more live and instant conventions. Drawing on the concepts of mediatization and journalistic interventionism to interpret editorial changes, our findings broadly indicate that the media logic shaping bulletins has changed from reflecting the ‘day’s news’ to covering more ‘news as it happens’ (as news channels now claim). We found an increasing reliance on less pre-scripted material and greater emphasis on live reporting from journalists (rather than external sources) who were routinely asked to instantly react, update, and interpret news, particularly in the world of politics. We suggest this represents a mediatization of television news bulletins, with broadcasters increasingly subscribing to a journalistic logic associated more with 24-hour news values than fixed time programming
Comparing levels of mediatization in television journalism: an analysis of political reporting on US and UK evening news bulletins
This comparative content analysis study (N = 946) examines how far political news is mediatized in the US and UK by systematically exploring the conventions used in television news bulletins. According to many of our mediatization of politics indicators – which included sound and imagebites, lip flaps, journalistic visibility, ‘wrapping up’, live and interpretive news – broadcasters with the most public service responsibilities supplied the highest level of mediatized political news. Our study thus appears to challenge conventional academic wisdom that US journalistic interventionism is greater than other advanced Western democracies and that enhanced commercialization is a precursor to higher degrees of mediatization. We suggest that the form, structure and style of journalism should be understood more carefully by scholars when making sense of how far news is mediatized, since the greater length of UK television news conventions and the ability to ‘go live’ longer allowed journalists greater freedom to interpret politics
The impact of macrosomia on cardiometabolic health in preteens: findings from the ROLO longitudinal birth cohort study
Abstract Background Macrosomia (birthweight ≥ 4 kg or ≥ 4.5 kg) is strongly associated with a predisposition to childhood obesity, which in turn is linked with adverse cardiometabolic health. Despite this, there is a lack of longitudinal investigation on the impact of high birthweight on cardiometabolic outcomes in youth. The preteen period represents an important window of opportunity to further explore this link, to potentially prevent cardiometabolic profiles worsening during puberty. Methods This is a secondary analysis of 9–11-year-olds (n = 405) born to mothers in the ROLO longitudinal birth cohort study, who previously delivered an infant with macrosomia. Preteens were dichotomised into those born with and without macrosomia, using two common cut-off criteria (birthweight ≥ 4 kg (n = 208) and < 4 kg; ≥ 4.5 kg (n = 65) and < 4.5 kg). Cardiometabolic health was assessed using anthropometry, dual-energy x-ray absorptiometry, blood pressure, heart rate, cardiorespiratory endurance (20-m shuttle run test), and non-fasting serum biomarkers for a subgroup (n = 213). Statistical comparisons between the two groups were explored using independent t-tests, Mann–Whitney U tests, and Chi-square tests. Crude and adjusted linear regression models investigated associations between macrosomia and preteen cardiometabolic outcomes. Results In total, 29.3% (n = 119) of preteens had overweight/obesity based on their BMI z-score. Preteens born ≥ 4 kg had lower median (IQR) C3 concentrations (1.38 (1.22, 1.52) g/L vs. 1.4 (1.26, 1.6) g/L, p = 0.043) and lower median (IQR) ICAM-1 concentrations (345.39 (290.34, 394.91) ng/mL vs. 387.44 (312.91, 441.83) ng/mL, p = 0.040), than those born < 4 kg. Those born ≥ 4.5 kg had higher mean (SD) BMI z-scores (0.71 (0.99) vs. 0.36 (1.09), p = 0.016), and higher median (IQR) lean mass (24.76 (23.28, 28.51) kg vs. 23.87 (21.9, 26.79) kg, p = 0.021), than those born < 4.5 kg. Adjusted linear regression analyses revealed birthweight ≥ 4 kg was negatively associated with C3 concentration (g/L) (B = − 0.095, 95% CI = − 0.162, − 0.029, p = 0.005) and birthweight ≥ 4.5 kg was positively associated with weight z-score (B = 0.325, 95% CI = 0.018, 0.633, p = 0.038), height z-score (B = 0.391, 95% CI = 0.079, 0.703, p = 0.014), lean mass (kg) (B = 1.353, 95% CI = 0.264, 2.442, p = 0.015) and cardiorespiratory endurance (B = 0.407, 95% CI = 0.006, 0.808, p = 0.047). Conclusion This study found no strong evidence to suggest that macrosomia is associated with adverse preteen cardiometabolic health. Macrosomia alone may not be a long-term cardiometabolic risk factor. Trial registration ISRCTN54392969 registered at www.isrctn.com
Bis(8-quinolinolato)aluminum ethyl complexes: Iso-Selective Initiators for rac-Lactide Polymerization
The synthesis and characterization of a series of bis(8-quinolinato)aluminum ethyl complexes, substituted at the 2-, 5-, and 7-positions on the 8-quinolinol ligand, are presented. These complexes are viable initiators for the ring-opening polymerization of rac-lactide in the presence of 1 equiv of isopropyl alcohol. The polymerization control is good, it shows a linear evolution of molecular weight as the polymerization progresses, the polylactide molecular weights are in close agreement with those determined on the basis of the reaction stoichiometry, and the polydispersity indices are narrow. The polymerization kinetics have been monitored, and the influence of the site of ligand substitution has been related to the rates. Some of the initiators show stereocontrol, producing PLA with a good probability of isotactic enchainment (P-i = 0.76)
