IntroductionUptake of couples’ HIV counselling and testing (couples’ HCT) can positively influence sexual risk behaviours and improve linkage to HIV care among HIV‐positive couples. However, less than 30% of married couples have ever tested for HIV together with their partners. We explored the motivations for and barriers to couples’ HCT among married couples in Rakai, Uganda.MethodsThis was a qualitative study conducted among married individuals and selected key informants between August and October 2013. Married individuals were categorized by prior HCT status as: 1) both partners never tested; 2) only one or both partners ever tested separately; and 3) both partners ever tested together. Data were collected on the motivations for and barriers to couples’ HCT, decision‐making processes from tested couples and suggestions for improving couples’ HCT uptake. Eighteen focus group discussions with married individuals, nine key informant interviews with selected key informants and six in‐depth interviews with married individuals that had ever tested together were conducted. All interviews were audio‐recorded, translated and transcribed verbatim and analyzed using Nvivo (version 9), following a thematic framework approach.ResultsMotivations for couples’ HCT included the need to know each other's HIV status, to get a treatment companion or seek HIV treatment together – if one or both partners were HIV‐positive – and to reduce mistrust between partners. Barriers to couples’ HCT included fears of the negative consequences associated with couples’ HCT (e.g. fear of marital dissolution), mistrust between partners and conflicting work schedules. Couples’ HCT was negotiated through a process that started off with one of the partners testing alone initially and then convincing the other partner to test together. Suggestions for improving couples’ HCT uptake included the need for couple‐ and male‐partner‐specific sensitization, and the use of testimonies from tested couples.ConclusionsCouples’ HCT is largely driven by individual and relationship‐based factors while fear of the negative consequences associated with couples’ HCT appears to be the main barrier to couples’ HCT uptake in this setting. Interventions to increase the uptake of couples’ HCT should build on the motivations for couples’ HCT while dealing with the negative consequences associated with couples’ HCT.
Subjunctive Conditionals
Authors: Ippolito Michela 
Published: September 2014

A proposal for a compositional semantics for subjunctive (or would) conditionals in English.
In this book, Michela Ippolito proposes a compositional semantics for subjunctive (or would) conditionals in English that accounts for their felicity conditions and the constraints on the satisfaction of their presuppositions by capitalizing on the occurrence of past tense morphology in both antecedent and consequent clauses. Very little of the extensive literature on subjunctive conditionals tries to account for the meaning of these sentences compositionally or to relate this meaning to their linguistic form; this book fills that gap, connecting the different lines of research on conditionals. Ippolito's proposal will be of interest both to linguists and to philosophers concerned with conditionals and modality more generally.
Ippolito reviews previous analyses of counterfactuals and subjunctive conditionals in the work of David Lewis, Robert Stalnaker, Angelika Kratzer, and others; considers the contrast between future simple past subjunctive conditionals and future past perfect subjunctive conditionals; presents a proposal for subjunctive conditionals that addresses puzzles left unsolved by previous proposals; reviews a number of presupposition triggers showing that they fit the pattern predicted by her proposal; and discusses an asymmetry between the past and the future among subjunctive conditionals, arguing that the best account of our linguistic intuitions must include an indeterministic view of the world.
Neighborhood as Refuge
Authors: Anguelovski Isabelle 
Published: September 2014

An examination of environmental revitalization efforts in low-income communities in Boston, Barcelona, and Havana that help heal traumatized urban neighborhoods.
Environmental justice as studied in a variety of disciplines is most often associated with redressing disproportionate exposure to pollution, contamination, and toxic sites. In Neighborhood as Refuge, Isabelle Anguelovski takes a broader view of environmental justice, examining wide-ranging comprehensive efforts at neighborhood environmental revitalization that include parks, urban agriculture, fresh food markets, playgrounds, housing, and waste management. She investigates and compares three minority, low-income neighborhoods that organized to improve environmental quality and livability: Casc Antic, in Barcelona; Dudley, in the Roxbury section of Boston; and Cayo Hueso, in Havana.
Despite the differing histories and political contexts of these three communities, Anguelovski finds similar patterns of activism. She shows that behind successful revitalization efforts is what she calls “bottom to bottom” networking, powered by broad coalitions of residents, community organizations, architects, artists, funders, political leaders, and at times environmental advocacy groups. Anguelovski also describes how, over time, environmental projects provide psychological benefits, serving as a way to heal a marginalized and environmentally traumatized urban neighborhood. They encourage a sense of rootedness and of attachment to place, creating safe havens that offer residents a space for recovery. They also help to bolster residents' ability to deal with the negative dynamics of discrimination and provide spaces for broader political struggles including gentrification. Drawing on the cases of Barcelona, Boston, and Havana, Anguelovski presents a new holistic framework for understanding environmental justice action in cities, with the right to a healthy community environment at its core.
Double Dividend
Authors: Jorgenson Dale W. , Goettle Richard J. , Ho Mun S. , Wilcoxen Peter J. 
Published: September 2014

A rigorous and innovative approach for integrating environmental policies and fiscal reform for the U.S. economy.
Energy utilization, especially from fossil fuels, creates hidden costs in the form of pollution and environmental damages. The costs are well documented but are hidden in the sense that they occur outside the market, are not reflected in market prices, and are not taken into account by energy users. Double Dividend presents a novel method for designing environmental taxes that correct market prices so that they reflect the true cost of energy. The resulting revenue can be used in reducing the burden of the overall tax system and improving the performance of the economy, creating the double dividend of the title.
The authors simulate the impact of environmental taxes on the U.S. economy using their Intertemporal General Equilibrium Model (IGEM). This highly innovative model incorporates expectations about future prices and policies. The model is estimated econometrically from an extensive 50-year dataset to incorporate the heterogeneity of producers and consumers. This approach generates confidence intervals for the outcomes of changes in economic policies, a new feature for models used in analyzing energy and environmental policies. These outcomes include the welfare impacts on individual households, distinguished by demographic characteristics, and for society as a whole, decomposed between efficiency and equity.
The Commons in History
Authors: Wall Derek 
Published: September 2014

An argument that the commons is neither tragedy nor paradise but can be a way to understand environmental sustainability.
The history of the commons—jointly owned land or other resources such as fisheries or forests set aside for public use—provides a useful context for current debates over sustainability and how we can act as “good ancestors.” In this book, Derek Wall considers the commons from antiquity to the present day, as an idea, an ecological space, an economic abstraction, and a management practice. He argues that the commons should be viewed neither as a “tragedy” of mismanagement (as the biologist Garrett Hardin wrote in 1968) nor as a panacea for solving environmental problems. Instead, Walls sees the commons as a particular form of property ownership, arguing that property rights are essential to understanding sustainability. How we use the land and its resources offers insights into how we value the environment.
After defining the commons and describing the arguments of Hardin's influential article and Elinor Ostrom's more recent work on the commons, Wall offers historical case studies from the United States, England, India, and Mongolia. He examines the power of cultural norms to maintain the commons; political conflicts over the commons; and how commons have protected, or failed to protect ecosystems. Combining intellectual and material histories with an eye on contemporary debates, Wall offers an applied history that will interest academics, activists, and policy makers.
Investigating the Psychological World
Authors: Haig Brian D. 
Published: September 2014

A broad theory of research methodology for psychology and the behavioral sciences that offers a coherent treatment of a range of behavioral research methods.
This book considers scientific method in the behavioral sciences, with particular reference to psychology. Psychologists learn about research methods and use them to conduct their research, but their training teaches them little about the nature of scientific method itself. In Investigating the Psychological World, Brian Haig fills this gap. Drawing on behavioral science methodology, the philosophy of science, and statistical theory, Haig constructs a broad theory of scientific method that has particular relevance for the behavioral sciences. He terms this account of method the abductive theory of method (ATOM) in recognition of the importance it assigns to explanatory reasoning. ATOM offers the framework for a coherent treatment of a range of quantitative and qualitative behavioral research methods, giving equal treatment to data-analytic methods and methods of theory construction.
Haig draws on the new experimentalism in the philosophy of science to reconstruct the process of phenomena detection as it applies to psychology; he considers the logic and purpose of exploratory factor analysis; he discusses analogical modeling as a means of theory development; and he recommends the use of inference to the best explanation for evaluating theories in psychology. Finally, he outlines the nature of research problems, discusses the nature of the abductive method, and describes applications of the method to grounded theory method and clinical reasoning. The book will be of interest not only to philosophers of science but also to psychological researchers who want to deepen their conceptual understanding of research methods and methodological concerns.

Influence of the basic state zonal flow on convectively coupled equatorial waves
Authors: Dias Juliana , Kiladis George N. 
Published: September 2014

AbstractObservational data are used to test the hypothesis that the basic state modulates the dispersion properties of convectively coupled equatorial waves (CCEWs). This hypothesis is based on shallow water theory, which predicts that the zonal speed of propagation of such tropospheric equatorial modes is altered by the equivalent depth and the basic zonal flow. Localized space‐time spectra are calculated to investigate how CCEW spectral peaks vary across the tropics and how they are affected by the variations in zonal wind observed geographically and by season. Doppler shifting by the basic state barotropic zonal flow is readily identified. Once this Doppler shifting is taken into account, the equivalent depths of CCEWs inferred from global power spectra are surprisingly uniform, both geographically and temporally. However, there are also detectable modulations that appear consistent with changes in vertical shear of the zonal flow, along with other shifts that are not as easily explained.
Current sheet scattering and ion isotropic boundary under 3‐D empirical force‐balanced magnetic field

AbstractTo determine statistically the extent to which current sheet scattering is sufficient to account for the observed ion isotropic boundaries (IBs) for <30 keV ions, we have computed IBs from our 3‐D empirical force‐balanced magnetic field, identified IBs in FAST observations, and investigated the model‐observation consistency. We have found in both model and FAST results the same dependences of IB latitudes on magnetic local time, ion energy, Kp, and solar wind dynamic pressure (PSW) levels: IB moves to higher latitudes from midnight toward dawn/dusk and to lower latitudes as energy increases and as Kp or PSW increases. The model predicts well the observed energy dependence, and the modeled IB latitudes match fairly well with those from FAST for Kp = 0. As Kp increases, the latitude agreement at midnight remains good but a larger discrepancy is found near dusk. The modeled IBs at the equator are located around the earthward boundary of highly isotropic ions observed by Time History of Events and Macroscale Interactions during Substorms at midnight and postmidnight, but with some discrepancy near dusk under high Kp. Thus, our results indicate that current sheet scattering generally plays the dominant role. The discrepancies suggest the importance of pitch angle scattering by electromagnetic ion cyclotron waves, which occur more often from dusk to noon and are more active during higher Kp. The comparison with the observed IBs is better with our model than under the nonforce‐balanced T89, indicating that using a forced‐balanced model improves the description of the magnetic field configuration and reinforces our conclusions regarding the role of current sheet scattering.
On the generation/decay of the storm‐enhanced density plumes: Role of the convection flow and field‐aligned ion flow

AbstractStorm‐enhanced density (SED) plumes are prominent ionospheric electron density increases at the dayside middle and high latitudes. The generation and decay mechanisms of the plumes are still not clear. We present observations of SED plumes during six storms between 2010 and 2013 and comprehensively analyze the associated ionospheric parameters within the plumes, including vertical ion flow, field‐aligned ion flow and flux, plasma temperature, and field‐aligned currents, obtained from multiple instruments, including GPS total electron content (TEC), Poker Flat Incoherent Scatter Radar (PFISR), Super Dual Auroral Radar Network, and Active Magnetosphere and Planetary Electrodynamics Response Experiment. The TEC increase within the SED plumes at the PFISR site can be 1.4–5.5 times their quiet time value. The plumes are usually associated with northwestward E × B flows ranging from a couple of hundred m s−1 to > 1 km s−1. Upward vertical flows due to the projection of these E × B drifts are mainly responsible for lifting the plasma in sunlit regions to higher altitude and thus leading to plume density enhancement. The upward vertical flows near the poleward part of the plumes are more persistent, while those near the equatorward part are more patchy. In addition, the plumes can be collocated with either upward or downward field‐aligned currents (FACs) but are usually observed equatorward of the peak of the Region 1 upward FAC, suggesting that the northwestward flows collocated with plumes can be either subauroral or auroral flows. Furthermore, during the decay phase of the plume, large downward ion flows, as large as ~200 m s−1, and downward fluxes, as large as 1014 m−2 s−1, are often observed within the plumes. In our study of six storms, enhanced ambipolar diffusion due to an elevated pressure gradient is able to explain two of the four large downward flow/flux cases, but this mechanism is not sufficient for the other two cases where the flows are of larger magnitude. For the latter two cases, enhanced poleward thermospheric wind is suggested to be another mechanism for pushing the plasma downward along the field line. These downward flows should be an important mechanism for the decay of the SED plumes.
A numerical investigation of wave‐breaking‐induced turbulent coherent structure under a solitary wave

Published: September 2014

AbstractTo better understand the effect of wave‐breaking‐induced turbulence on the bed, we report a 3‐D large‐eddy simulation (LES) study of a breaking solitary wave in spilling condition. Using a turbulence‐resolving approach, we study the generation and the fate of wave‐breaking‐induced turbulent coherent structures, commonly known as obliquely descending eddies (ODEs). Specifically, we focus on how these eddies may impinge onto bed. The numerical model is implemented using an open‐source CFD library of solvers, called OpenFOAM, where the incompressible 3‐D filtered Navier‐Stokes equations for the water and the air phases are solved with a finite volume scheme. The evolution of the water‐air interfaces is approximated with a volume of fluid method. Using the dynamic Smagorinsky closure, the numerical model has been validated with wave flume experiments of solitary wave breaking over a 1/50 sloping beach. Simulation results show that during the initial overturning of the breaking wave, 2‐D horizontal rollers are generated, accelerated, and further evolve into a couple of 3‐D hairpin vortices. Some of these vortices are sufficiently intense to impinge onto the bed. These hairpin vortices possess counter‐rotating and downburst features, which are key characteristics of ODEs observed by earlier laboratory studies using Particle Image Velocimetry. Model results also suggest that those ODEs that impinge onto bed can induce strong near‐bed turbulence and bottom stress. The intensity and locations of these near‐bed turbulent events could not be parameterized by near‐surface (or depth integrated) turbulence unless in very shallow depth.
Sea surface salinity variability in the East China Sea observed by the Aquarius instrument

Published: September 2014

AbstractThis study demonstrates that the spaceborne Aquarius instrument is able to monitor the sea surface salinity (SSS) variations in the East China Sea (ECS) with the spatial resolution of about 150 km at 7 day interval, where routine observations are difficult. The two geophysical contaminants enter the sidelobes of the Aquarius antenna and bias the coastal SSS low: the emission from the land surface and the radiofrequency interference (RFI). Away from about one Aquarius pixel (150 km) from the coastline, the Aquarius SSS is fairly insensitive (less than about 0.2 psu) to the radiometric details of the method to correct for the land emission. The ascending orbits appear to be affected by unfiltered RFI much less than the descending tracks. The Aquarius SSS along the ascending tracks is low over the ECS by 0.40–0.93 psu (with respect to the in situ data during the two separate 7 day periods) and is biased low by 0.41–1.07 psu (accuracy, or the time‐mean of difference from the regional model along three Aquarius tracks over a 18 month period). The presence of the ascending and descending differences in the Aquarius SSS, and the spatially widespread bias suggest that the bias is attributed to the unfiltered RFI originating from strong point sources (rather than to the land contamination from weak distributed sources, or to other seasonally varying geophysical contaminants). Despite the bias, the Aquarius data describe well the temporal and spatial variability of the ECS SSS. The temporal trend and magnitude of salinity changes agree remarkably between Aquarius and a regional numerical model, during both the freshwater discharge season from the Yangtze river and the rest of the year. The precision of the Aquarius observation in the ECS is comparable with the Aquarius mission requirement (0.2 psu one‐sigma for a monthly average over the open ocean). The river discharge rate correlates with the Aquarius SSS with the coefficient of 0.71 on a seasonal scale with the discharge leading the SSS changes. The Aquarius SSS increases away from the coast, in response to the river outflow. The interannual changes in the Aquarius SSS capture the effect of the regional drought in summer 2013.
Laboratory study on coprecipitation of phosphate with ikaite in sea ice

Published: September 2014

AbstractIkaite (CaCO3·6H2O) has recently been discovered in sea ice, providing first direct evidence of CaCO3 precipitation in sea ice. However, the impact of ikaite precipitation on phosphate (PO4) concentration has not been considered so far. Experiments were set up at pH from 8.5 to 10.0, salinities from 0 to 105, temperatures from −4°C to 0°C, and PO4 concentrations from 5 to 50 µmol kg−1 in artificial sea ice brine so as to understand how ikaite precipitation affects the PO4 concentration in sea ice under different conditions. Our results show that PO4 is coprecipitated with ikaite under all experimental conditions. The amount of PO4 removed by ikaite precipitation increases with increasing pH. Changes in salinity (S ≥ 35) as well as temperature have little impact on PO4 removal by ikaite precipitation. The initial PO4 concentration affects the PO4 coprecipitation. These findings may shed some light on the observed variability of PO4 concentration in sea ice.
Enhanced sea‐air CO2 exchange influenced by a tropical depression in the South China Sea

Published: September 2014

AbstractShip measurements made 2 days after the passage of a tropical depression (TD) in the South China Sea (SCS, April 2011) showed two contrasted responses of the partial pressure of CO2 at sea surface (pCO2,sw). In low sea‐surface salinity (SSS) water, pCO2,sw was low (349 ± 7 μatm), and the area was a carbon sink (−4.7 ± 1.8 mmol CO2 m−2 d−1), whereas in water with high SSS and chlorophyll a and low dissolved oxygen and sea surface temperature, pCO2,sw was higher than for normal SCS water (376 ± 8 versus 362 ± 4 μatm) and the area was a carbon source (1.2 ± 3.1 mmol CO2 m−2 d−1). Satellite data showed two large areas of low SSS before the TD, which were likely influenced by rainfall, and these areas were considered to have low pCO2,sw because of their low SSS. The high pCO2,sw after the TD is explained by the uplifting to the surface of deeper and CO2‐rich water, due to winds accompanied by the TD. The difference in sea‐air CO2 flux between the TD‐affected area and the lower‐SSS water was 1.99 + 4.70 = 6.7 mmol CO2 m−2 d−1, indicating a 100% change caused by the TD compared to the average seasonal value in spring in southern SCS (3.3 ± 0.3 mmol CO2 m−2 d−1). Undersaturation of CO2 prior to the TD due to dilution by freshwater and the preexisting cold eddy, and slow translation speed of the TD, are considered to account for the CO2 flux change.
