A Unified Formulation of Radiative Transfer in Plane-Parallel Atmospheres Based on General Decomposition of Radiance. Part II: An Exemplifying Application to the Hemispherical Harmonics Method with Four Components
Authors: Wang Biao 
Published: September 2017

Abstract
Based on the unified formulation, the so-called hemispherical harmonics method with four components (HSHM4) is derived following the general procedure described in the first paper of this series. The numerical results of this method, including the flux reflections, transmissions, and absorptions for different optical depths, incident beam angles, and single-scattering albedos and the emissions for different optical depths and single-scattering albedos, are reported, in comparison with the results of DISORT with 128 streams as a benchmark. The application of the method to the radiation scheme for climate models is illustrated with the numerical results, including the heating-rate profiles for the shortwave and longwave radiation, radiative fluxes at the top and the bottom boundaries of the atmosphere, and the actinic flux profiles, for typical model atmospheres of Earth and different clear or cloudy conditions. The comparison of results with those of the discrete ordinate methods (DOMs) and the spherical harmonic method (SHM) with four components shows that the HSHM4 has comparable accuracy with the four-stream DOM with double-Gaussian quadrature and is more accurate than the four-stream SHM and the four-stream DOM with full-range Gaussian quadrature in general, especially in the cases of longwave radiation when the multiple-scattering effect should be accounted for. The HSHM4 can be deployed consistently to all of the bands without artificial division between the longwave and shortwave. The development and validation of the HSHM4 exhibit the usefulness of the unified formulation in the study of atmospheric radiative transfer.
Lower-Tropospheric Eddy Momentum Fluxes in Idealized Models and Reanalysis Data
Authors: Lutsko Nicholas J. , Held Isaac M. , Zurita-Gotor Pablo , O’Rourke Amanda K. 
Published: September 2017

Abstract
In Earth’s atmosphere eddy momentum fluxes (EMFs) are largest in the upper troposphere, but EMFs in the lower troposphere, although modest in amplitude, have an intriguing structure. To document this structure, the EMFs in the lower tropospheres of a two-layer quasigeostrophic model, a primitive equation model, and the Southern Hemisphere of a reanalysis dataset are investigated. The lower-tropospheric EMFs are very similar in the cores of the jets in both models and the reanalysis data, with EMF divergence (opposing the upper-tropospheric convergence) due to relatively long waves with slow eastward phase speeds and EMF divergence (as in the upper troposphere) due to shorter waves with faster eastward phase speeds.
As the two-layer model is able to capture the EMF divergence by long waves, a qualitative picture of the underlying dynamics is proposed that relies on the negative potential vorticity gradient in the lower layer of the model. Eddies excited by baroclinic instability mix efficiently through a wide region in the lower layer, centered on the latitude of maximum westerlies and encompassing the lower-layer critical latitudes. Near these critical latitudes, the mixing is enhanced, resulting in increased EMF convergence, with compensating EMF divergence in the center of the jet. The EMF convergence at faster phase speeds is due to deep eddies that propagate on the upper-tropospheric potential vorticity gradient.

Abstract
The number and refinement of gridded meteorological datasets are on the rise at the global and regional scales. Although these datasets are now commonly used for hydrological modeling, the representation of precipitation amount and timing is crucial to correctly model streamflow. The Génie Rural à 4 paramètres journalier (GR4J) conceptual hydrological model combined with the CEMANEIGE snow routine was calibrated using four temperature and precipitation datasets [Système d’analyse fournissant des renseignements atmosphériques à la neige (SAFRAN), Mesoscale Analysis (MESAN), E-OBS, and Water and Global Change (WATCH) Forcing Data ERA-Interim (WFDEI)] on 931 French gauged catchments ranging in size from 10 to 10 000 km2. The efficiency of the calibrated hydrological model in simulating streamflow was higher for the models calibrated on high-resolution meteorological datasets (SAFRAN, MESAN) compared to coarse-resolution datasets (E-OBS, WFDEI), as well as for reanalysis (SAFRAN, MESAN, WFDEI) compared to datasets based on interpolation only (E-OBS). The systematic decrease in efficiency associated with precipitation bias or temporality highlights that the use of a hydrological model calibrated on meteorological datasets can assess these datasets, most particularly precipitation. It appears essential that datasets account for high-resolution topography to accurately represent elevation gradients and assimilate dense ground-based observation networks. This is particularly emphasized for hydrological applications in mountainous areas and areas subject to finescale events. For hydrological applications on nonmountainous regions, not subject to finescale events, both regional and global datasets give satisfactory results. It is crucial to continue improving precipitation datasets, especially in mountainous areas, and to assess their sensitivity to eventual corrupted observations. These datasets are essential to correct the bias of climate model outputs and to investigate the impact of climate change on hydrological regimes.
Interdecadal Climate Variations Controlling the Water Level of Lake Qinghai over the Tibetan Plateau

Abstract
Using observed and reanalysis data, the pronounced interdecadal variations of Lake Qinghai (LQH) water levels and associated climate factors were diagnosed. From the 1960s to the early 2000s, the water level of LQH in the Tibetan Plateau has experienced a continual decline of 3 m but has since increased considerably. A water budget analysis of the LQH watershed suggested that the water vapor flux divergence is the dominant atmospheric process modulating precipitation and subsequently the lake volume change . The marked interdecadal variability in and was found to be related to the North Pacific (NP) and Pacific decadal oscillation (PDO) modes during the cold season (November–March). Through empirical orthogonal function (EOF) and regression analyses, the water vapor sink over the LQH watershed also responds significantly to the summer Eurasian wave train modulated by the low-frequency variability associated with the cold season NP and PDO modes. Removal of these variability modes (NP, PDO, and the Eurasian wave train) led to a residual uptrend in the hydrological variables of , , and precipitation, corresponding to the net water level increase. Attribution analysis using the Coupled Model Intercomparison Project phase 5 (CMIP5) single-forcing experiments shows that the simulations driven by greenhouse gas forcing produced a significant increase in the LQH precipitation, while anthropogenic aerosols generated a minor wetting trend as well.
Energetic Submesoscales Maintain Strong Mixed Layer Stratification during an Autumn Storm
Authors: Whitt Daniel B. , Taylor John R. 
Published: September 2017

AbstractAtmospheric storms are an important driver of changes in upper-ocean stratification and small-scale (1–100 m) turbulence. Yet, the modifying effects of submesoscale (0.1–10 km) motions in the ocean mixed layer on stratification and small-scale turbulence during a storm are not well understood. Here, large-eddy simulations are used to study the coupled response of submesoscale and small-scale turbulence to the passage of an idealized autumn storm, with a wind stress representative of a storm observed in the North Atlantic above the Porcupine Abyssal Plain. Because of a relatively shallow mixed layer and a strong downfront wind, existing scaling theory predicts that submesoscales should be unable to restratify the mixed layer during the storm. In contrast, the simulations reveal a persistent and strong mean stratification in the mixed layer both during and after the storm. In addition, the mean dissipation rate remains elevated throughout the mixed layer during the storm, despite the strong mean stratification. These results are attributed to strong spatial variability in stratification and small-scale turbulence at the submesoscale and have important implications for sampling and modeling submesoscales and their effects on stratification and turbulence in the upper ocean.

Published: September 2017

Background: Guidelines on the management of aneurysmal subarachnoid hemorrhage (aSAH) recommend euvolemia, whereas hypervolemia may cause harm. We investigated whether high early fluid input is associated with delayed cerebral ischemia (DCI), and if fluid input can be safely decreased using transpulmonary thermodilution (TPT). Methods: We retrospectively included aSAH patients treated at an academic intensive care unit (2007-2011; cohort 1) or managed with TPT (2011-2013; cohort 2). Local guidelines recommended fluid input of 3 L daily. More fluids were administered when daily fluid balance fell below +500 mL. In cohort 2, fluid input in high-risk patients was guided by cardiac output measured by TPT per a strict protocol. Associations of fluid input and balance with DCI were analyzed with multivariable logistic regression (cohort 1), and changes in hemodynamic indices after institution of TPT assessed with linear mixed models (cohort 2). Results: Cumulative fluid input 0 to 72 hours after admission was associated with DCI in cohort 1 (n=223; odds ratio [OR] 1.19/L; 95% confidence interval 1.07-1.32), whereas cumulative fluid balance was not. In cohort 2 (23 patients), using TPT fluid input could be decreased from 6.0 ± 1.0 L before to 3.4 ± 0.3 L; P = .012), while preload parameters and consciousness remained stable. Conclusion: High early fluid input was associated with DCI. Invasive hemodynamic monitoring was feasible to reduce fluid input while maintaining preload. These results indicate that fluid loading beyond a normal preload occurs, may increase DCI risk, and can be minimized with TPT.
Online Lactation Education for Healthcare Providers: A Theoretical Approach to Understanding Learning Outcomes
Authors: Watkins Amanda L. , Dodgson Joan E. , McClain Darya Bonds 
Published: September 2017

Background: Breastfeeding competencies are not standardized in healthcare education for any of the health professions. A few continuing education/professional development programs have been implemented, but research regarding the efficacy of these programs is scarce. Research aim: After a 45-hour lactation course, (a) Does breastfeeding knowledge increase? (b) Do beliefs and attitudes about infant feeding improve? (c) Does perceived behavioral control over performance of evidence-based lactation support practices increase? and (d) Do intentions to carry out evidence-based lactation support practices increase? Methods: A nonexperimental pretest–posttest self-report survey design was conducted with a nonprobability sample of participants ( N = 71) in a lactation course. Theory of Planned Behavior variables were measured and a before–after course analysis was completed. Results: Significantly higher scores were found on the posttests for knowledge, beliefs about breastfeeding scale, and the perceived behavioral control scale. Participants’ self-efficacy increased after the course; their beliefs about social norms and their ability to effect change in their workplaces did not change significantly. Participants’ intention to perform actions that are consistent with the evidence-based breastfeeding supportive behaviors increased significantly. Positive beliefs about formula feeding significantly increased; this was unexpected. Conclusion: The Theory of Planned Behavior provided a useful approach for examining more meaningful learning outcomes than the traditional knowledge and/or satisfaction outcomes. This study was the first to suggest that more meaningful learning outcomes are needed to evaluate lactation programs. However, it is not enough to educate healthcare providers in evidence-based practice; the places they practice must have the infrastructure to support evidence-based practice.
The Effect of International Joint Research to the Research Performance: The Case of the Global Research Laboratory and the Basic Research Laboratory Programme
Authors: Kang Jinwon 
Published: September 2017

Korea has been in a transition from catching-up to post-catching-up period. In this circumstance, the strengthening of basic research is one of the important strategies. This research investigates the main factors influencing research performance through the international joint research (IJR). The literature about determinants of performance of R&D and the effect of IJR to the performance is reviewed. The research performance of IJR will be investigated in comparison with IJR programme and general R&D programme as a result of international and domestic research activities. The comparison about research performance will be performed using independent samples test on the modified impact factor of papers. The main factors influencing the performance are investigated in terms of research budget, capacity, number of researchers and international collaboration on the basis of previous researches. The main finding is that the research capacity is basic requirement to increase the modified impact factor and the main factors influencing research performance through IJR are the network size and the number of contact in this research. Its recommendations, in accordance with this finding, are as follows. The government should support researcher to have more and easier contact with foreign researchers in terms of budget and programme structure and institutional improvement, including evaluation system. The additional budget on the existing programme and easy usage of research budget in the IJR are the good ways to promote the IJR activities through renovation of basic R&D programme structure. The additional credit to the research groups with bigger research networks should be considered in the selection process and ex-post evaluation process. Long-term and sustainable support for the research is the basic requirement to improve the capacity of researchers and obtain better research performance.

Authors: Charvet Leigh E , Dobbs Bryan , Shaw Michael T , Bikson Marom , Datta Abhishek , Krupp Lauren B 
Published: September 2017

Background: Fatigue is a common and debilitating feature of multiple sclerosis (MS) that remains without reliably effective treatment. Transcranial direct current stimulation (tDCS) is a promising option for fatigue reduction. We developed a telerehabilitation protocol that delivers tDCS to participants at home using specially designed equipment and real-time supervision (remotely supervised transcranial direct current stimulation (RS-tDCS)). Objective: To evaluate whether tDCS can reduce fatigue in individuals with MS. Methods: Dorsolateral prefrontal cortex left anodal tDCS was administered using a RS-tDCS protocol, paired with 20 minutes of cognitive training. Here, two studies are considered. Study 1 delivered 10 open-label tDCS treatments (1.5 mA; n = 15) compared to a cognitive training only condition ( n = 20). Study 2 was a randomized trial of active (2.0 mA, n = 15) or sham ( n = 12) delivered for 20 sessions. Fatigue was assessed using the Patient-Reported Outcomes Measurement Information System (PROMIS)—Fatigue Short Form. Results and conclusion: In Study 1, there was modest fatigue reduction in the active group (−2.5 ± 7.4 vs −0.2 ± 5.3, p = 0.30, Cohen’s d = −0.35). However, in Study 2 there was statistically significant reduction for the active group (−5.6 ± 8.9 vs 0.9 ± 1.9, p = 0.02, Cohen’s d = −0.71). tDCS is a potential treatment for MS-related fatigue.
“I could’ve had a better life”: Reflective life reviews told by late-middle-aged and older women and men with ongoing long-term alcohol problems
Authors: Bergström Magdalena 
Published: September 2017

Aim: This study accounts for how people aged 55-69 with ongoing long-term alcohol problems conceptualize past, present and future. Methods: A total of 19 interviews were performed, from which reflective life reviews were obtained and analyzed as narrative life accounts. Three structuring thematic traits were identified: resentment of life, acceptance of life and gratitude towards life. Results: The study shows how past, present and future intertwine into meaningful entities incorporating certain governing master narratives about recovery, familiar for example from expert discourse and the AA movement. When it comes to the theme of resentment, the participants articulated disappointment over what life had become and emphasized especially the missed work-related opportunities that the drinking had caused. In the theme of acceptance letting go of the past was viewed as important for creating a sober future. Within the dimension of gratitude the past was seen as a resource for self-development and future recovery. Conclusions: How long-term alcohol problems are conceptualized in the long view of a life narrative may have great implications for outlooks of a sober future. A closer look at the social and cultural material incorporated in the stories of this age group is an important task for future research.
Den aldrende LAR pasienten
Authors: Nyhagen Hege Tollefsen , Waal Helge 
Published: September 2017

Background: Opioid maintenance treatment (OMT) secures a low mortality in a vulnerable population and is often a lifelong treatment. One would therefore expect an increasing prevalence of OMT among the elderly. This article describes a study with three elements; a literature review, an investigation of occurrence and an exploration of elderly patients’ needs and experiences. Material and methods: PsycINFO, Ovid Medline and Embase were searched with reference words for opioid maintenance and age. Norway has a national cohort study of patients in OMT describing recruitment, retention in treatment, age and mortality. A prognosis of numbers in treatment older than 50 and 60 years were extrapolated based on probabilistic premises. Finally, a qualitative interview study of OMT patients in two municipalities near Oslo was performed. Five OMT patients aged between 58 and 64 years were interviewed with open questions on thoughts, needs and experiences. Findings: The review points to an increasing population with psychiatric and somatic comorbidities and diverse needs. Their opinions and experiences seem largely unexplored. The population estimates indicate that Norway by 2018 will have between 3084 and 3567 individuals older than 50 years and between 201 and 302 individuals older than 60 years in OMT. The qualitative study demonstrated that the elderly OMT patient typically attributes their being alive to OMT. It is a life with a high prevalence of ailments and diseases. Their somatic diseases are mostly adequately treated by their GP, but they feel left alone with a high level of mental problems and loneliness. They miss follow-up from the OMT and social services and are not met on existential thoughts and sorrow for their life. A wish to end OMT during their lifetime is noteworthy. This would necessitate a close collaboration with the OMT services and support from a social network. Conclusions: The study points to insufficient knowledge of and strategies to meet an increasing number of individuals with composite problems in OMT. The numbers will remain too small to warrant specially designed local projects, but large enough to necessitate awareness and competencies in the ordinary municipal health and social services.
How do family pressure, health and ambivalence factor into entering alcohol treatment? Experiences of people aged 60 and older with alcohol use disorder
Authors: Emiliussen Jakob , Andersen Kjeld , Nielsen Anette S. 
Published: September 2017

Aim: This qualitative study is concerned with the motivations that lead older adults to enter treatment for alcohol problems. There is a need to expand our understanding of the unique characteristics and problems of this population to be able to devise specialised and effective treatments and preventive measures. Method: We conducted an analysis of secondary findings from interview data collected in a qualitative interpretative phenomenological analysis (IPA) study. Our participants were 12 elderly people aged 60 years or more who had experienced late-onset alcohol use disorder. Transcription, categorisation, collapsing and analysis were conducted rigorously in accordance with the IPA standards. Findings: Family can function as a pressure structure in terms of fostering motivation for treatment. Participants were to a certain extent ambivalent about treatment, which led them to devaluing treatment and its effects. Our results are on par with comparable results from other studies. Conclusion: Older adults who experience very-late-onset of alcohol use disorder experience familial pressure and health concerns which lead them to enter treatment. Our participants seemed ambivalent about treatment and its necessity, which seems to lead to a devaluation of therapy.
Patterns of polydrug use among pregnant substance abusers
Authors: Reitan Therese 
Published: September 2017

Aim: Studies of drug use during pregnancy have generally focused on individual substances or specific combinations of drugs. The aim of this article is to increase our knowledge about polydrug use and pregnancy in a Nordic context by describing the sociodemographic characteristics of a clinical population of pregnant women with severe substance use, examining the scope and type of polydrug use and analysing factors associated with concurrent use of many, as opposed to a few, drugs. Method: A cross-sectional study of pregnant women on admission to compulsory care for substance abuse in Sweden between 2000 and 2009 ( n = 119 women, representing 128 pregnancies). Data were retrieved from administrative registers and client records. Univariate links between demographic, social, obstetrical, treatment history variables and polydrug use were examined. Binary logistic regression was used to analyse the association between explanatory variables and polydrug use. Results: The average number of drugs being used concurrently was 2.65, and injection drug use was recorded in 73% of the pregnancies. Opiates and amphetamines were the most common primary drugs, followed by alcohol. The likelihood of polydrug use increased with first trimester pregnancy, planned (as opposed to emergency) committals, as well as the combination of partner substance abuse and injection drug use. Conclusions: Polydrug use was widespread among pregnant substance abusers. Policies, interventions and research often focus on individual drugs separately, but for clinical populations in particular there is a need to address drug use broadly, including a systematic recording of smoking habits. This also entails awarding more attention to those not eligible for established interventions, such as opiate maintenance treatment, and giving more consideration to a variety of life circumstances, such as partner drug use.
