Water, water everywhere: dehydration in the midst of plenty – An observational study of barriers and enablers to adequate hydration in older hospitalized patients

While dehydration is common in older patients and is associated with poor outcomes, it has been infrequently studied in the hospital setting. Thus, the aim of this study was to identify potential barriers and enablers to the maintenance of adequate hydration in older patients in an acute hospital environment. An observational study, involving patients aged 60 years and older admitted to an acute care hospital in Queensland, Australia, was undertaken. Forty-four patients were observed during mealtimes, and chart and room audits were performed to identify hydration management strategies, weight records and the presence or absence of fluid balance charts. Results revealed a number of system and practice-related barriers including patient difficulties with opening fluid containers and low levels of documentation of hydration management strategies. Addressing these issues is an important first step towards improving the management of hydration in medically ill older hospital patients.
Plant functional group composition in tallgrass prairie: development of a rapid assessment method for measuring vegetation integrity

Monitoring of plant communities is critical for identifying trends and assessing the impact of management. Current methods of ecological monitoring typically involve collection of species-level data and expertise in plant identification, procedures that can be time-consuming and costly. Because many agencies rely largely on volunteer labor, a rapid assessment index is needed that is both effective and designed for volunteers to use. Such an index would allow for frequent monitoring between more intense monitoring events and for quick assessment of sites. A method of assessing prairie site quality using plant functional groups was developed and tested against species-level indices for 15 prairie remnants and plantings ranging widely in quality to determine whether functional group information could be useful for constructing a rapid assessment index. Significant correlations were found between the functional group index and all species-level indices tested. The index also differentiated between high-quality remnants and plantings. If this simplified index provides meaningful information, it might be a useful tool for evaluation of management and restoration progress when time and expertise are limited. Observed differences in functional composition between plantings and remnants might also serve as a guide for improving habitat reconstructions.
Transport of semivolatile organic compounds to the Tibetan Plateau: Monthly resolved air concentrations at Nam Co

[1] A flow-through sampler was deployed to record the seasonal variability of the atmospheric concentrations of semivolatile organic compounds (SOCs) at a remote research station located close to Nam Co Lake on the Tibetan plateau. Between October 2006 and February 2008, fifteen consecutive one month-long samples, with air volumes ranging from 4,500 to 16,000 m3, were taken and analyzed for polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs) and organochlorine pesticides (OCPs). Separate analysis of three polyurethane plugs in series in combination with frontal chromatographic theory allows for the correction of the break-through observed for the most volatile SOCs. The concentrations of Σ56PCB in air range from 0.10 to 2.6 pg·m−3 and are among the lowest values ever reported. Levels of OCPs at Nam Co are generally also very low, particularly during wintertime. The concentrations of hexachlorocyclohexanes (HCHs), endosulfans, and various dichlorodiphenyltrichloroethane (DDT) related substances display a distinct seasonal variability consistent with the monsoon. Back-trajectory analysis reveals that higher OCP levels during summer correlate with air mass origin south of the Himalayas. A high α/γ-HCH ratio and a non-racemic composition of α-HCH during July/August suggest that evaporation from Nam Co Lake contributes to the relatively high concentrations of α-HCH (averaging ca. 91 pg·m−3) recorded in the summertime atmosphere.
Elemental composition and bacterial occurrence in sediment samples on two sides of Brøggerhalvøya, Svalbard

ABSTRACT The present study was conducted to determine the elemental concentration and bacterial presence in the ocean on the two sides of Brøggerhalvøya, a peninsula in Svalbard. Sediments from 25 different locations were collected and subjected to elemental analysis using inductively coupled plasma mass spectrometry (ICPMS). In total, 21 elements were analysed. The elements in their decreasing order of concentrations on the Kongsfjorden side of Brøggerhalvøya were Fe> Mn> Ba > V > Zn > Sr > Rb > Cr > Li > Ni > As > Pb > Cu > Co > Cs >Ag > Be > U> Bi >Tl > Cd while that for Forlandsendet side of Brøggerhalvøya they were Fe > Ba >Mn > V> Sr > Zn > Rb > Cr > Li > Ni > Pb > Cu > As > Co > Cs > Be > U> Tl > Bi > Cd. On the other hand, at a coastal outcrop, elements in their decreasing order of concentration were Fe > Mn > Cr > Sr > Ba > Rb > Cr > Zn > V > Rb > Ni > Li > Co > Cu > As > Pb > Cs > Be > Cd > Tl > U > Bi. AMS dates confirmed the age of outcrop sediment to be 12,496 to 42,500 BP. The crustal enrichment factor calculated for all the elements with reference to Fe values, demonstrates that the elements have derived from a crustal source. Total bacterial counts ranged from 3.30 × 105 to 3.02 × 106 per gm soil sediment. Culturable bacterial counts in these sediments were between 2.00 × 102 to 2.09 × 105 CFU's per gm. Overall comparison showed high Fe and Mn concentrations around Brøggerhalvøya, due to the presence of specific bacteria which play key roles in metal cycling and carry out biogeochemical transformations.

The Effect of Geography and Personal Experience on Attitudes and Perceptions of the Mexican Gray Wolf Reintroduction

This research examines the attitudes and perceptions of residents in Catron County and Harding County, New Mexico regarding the Mexican gray wolf reintroduction program under the Endangered Species Act. Catron County is within the wolf recovery zone and residents must deal with consequences of having wolves in the area. Harding County is located on the opposite side of the state and is removed from the wolf reintroduction area. Understanding the perceived concerns and benefits of the wolf reintroduction program and if those concerns change based on geographic proximity to the reintroduction can reveal whether cultural biases or personal experience with the

Evaluation on rare earth elements of Brazilian agricultural supplies

This work focuses on the determination of rare earth elements (REE) in Brazilian agricultural supplies by instrumental neutron activation analysis (INAA). The results obtained have shown that La, Ce, Nd, Sm, Eu, Tb, Yb, Lu and Sc are present within a large range of mass fractions in the agricultural supplies analysed. The thermophosphate and single superphosphate showed the highest mass fractions of REE. Considering the recommended dose and long-term use, NPK fertilizers, single superphosphate and thermophosphate can significantly increase the content of REE in soil and may cause harmful effects to environment and humans. Key words: Agricultural supplies, rare earth elements, lanthanoids, phosphate fertilizer, INAA.

Welfare-Based Monetary Policy Rules in an Estimated DSGE Model of the Us Economy

We develop and estimate a stylized micro-founded model of the US economy. Next we compute the parameters of a simple interest rate policy rule that maximizes the unconditional mean of utility. We show that such a welfare-based rule lies close to the Taylor efficiency frontier. A counterfactual analysis assesses to what extent using such a rule as a guideline for monetary policy would have helped to avoid the inflationary swings of the 1970s and reduce the severity of boom and bust cycles. The paper also provides estimates of the welfare implications of business cycle variability and discusses their relevance. JEL Classification: C51, E31, E52
The Pacific Subsurface Countercurrents and an Inertial Model

Abstract The Tsuchiya jets, or subsurface countercurrents, extend across the Pacific Ocean carrying 7 (±2) × 106 m3 s−1 eastward on each side of the equator. Mean meridional sections of potential temperature, salinity, neutral density anomaly, and the square of buoyancy frequency are presented for the western, central, and eastern tropical Pacific Ocean. These sections are used together with maps of depth and salinity on isopycnals, as well as thickness between isopycnals, to describe the evolution of the Tsuchiya jets as they flow from west to east. An inertial-jet model is formulated in which conservation of the Bernoulli function and potential vorticity combine with the eastward shoaling of the tropical pycnocline to dictate the jet structure. This model jet is consistent with a number of features of the Tsuchiya jets: their roughly constant volume transports, their advection of properties such as salinity and oxygen over long zonal distances, their rapidity and narrowness, their poleward shift from we.
Easier Said Than Done: The Failure of Top-Level Cybersecurity Advice for Consumer IoT Devices

Consumer IoT devices are generally assumed to lack adequate default security, thus requiring user action. However, it may not be immediately clear to users what action to take and how. This uncertainty begs the question of what the minimum is that the user-base can reliably be asked to do as a prompt to secure their devices. To explore this question, we analyze security actions advocated at a national level and how these connect to user materials for a range of specific devices. We identify four pieces of converging advice across three nation-level initiatives. We then assess the extent to which these pieces of advice are aligned with instruction materials for 40 different IoT devices across five device classes (including device manuals and manufacturer websites). We expose a disconnect between the advice and the device materials. A stunning finding is that there is not a single assessed device to which all four top pieces of converging advice can be applied. At best, the supporting materials for 36 of the 40 devices provide sufficient information to apply just two of the four pieces of advice, typically the installation and enabling of (auto)updates. As something of a contradiction, it is necessary for a non-expert user to assess whether expert advice applies to a device. This risks additional user burden and proxy changes being made without the proposed security benefits. We propose recommendations, including that governments and researchers alike should declare their own working models of IoT devices when considering the user view.
Structure and Depositional Environment of the Vendian Complex in the Southeastern White Sea Area

The subdivision and correlation scheme of the Vendian Complex is revised based on new data from outcrops along the eastern margin of the Baltic Shield (the southeastern White Sea area) and recently drilled boreholes. According to the established cyclic architecture of the sequence, the Vendian Complex is divided into the Lyamtsa, Verkhovka, Zimnie Gory, and Erga formations. Principal lithologic units of these subdivisions are described, and their facies relations and depositional environment are considered. It is suggested that the Ven- dian Complex accumulated in offshore settings as a result of southwestern progradation of a deltaic depositional system.
In-Orbit Calibration Adjustment of the Nimbus-7 SMMR

Abstract The procedure for converting raw antenna signals (counts) from the Nimbus-7 Scanning Multichannel Microwave Radiometer (SMMR) to microwave radiances is described. The procedure entails taking the raw data stored on TAT data tapes, applying an interim prelaunch calibration, correcting for polarization mixing, and finally adjusting the calibration so that the observations conform to model calculations of oceanic radiances. The results are stored on TCT data tapes with the same format as the TATS, i.e., the basic sampling interval of the SMMR is retained. The properties of the TCTs are compared with those of the other basic SMMR radiance data product, the CELL tapes, in which the integrated fields-of-view (IFOVS) have been averaged into cells with coarser sampling intervals and in which the prelaunch calibration is the final one used.

Evidencing land cover dynamics and tropical forest seasonality : the benefit of 13 years of daily global observation (SPOT-VEGETATION)

Facing environmental issues in a global change context requires improving our knowledge about the land surface and its dynamics. Today, the accumulation of satellite time series at moderate resolution constitutes unique datasets to monitor Earth’s surface evolution on each squared km. The ambition of this thesis was to exploit the multispectral reflectance variability as observed by the SPOT-VEGETATION time series (1999-2011) to characterize land surface dynamics at multi-annual and seasonal scales. Because of their single year strategy, current global land cover maps are sensitive to temporary events and to year-to-year variation related to meteorological and phenology change. An innovative land cover mapping approach takes advantage of the long time series to derive a multi-year global land cover map. This was found efficient to reduce the sensitivity to the observation period found in all global annual maps. In addition, a change detection method capitalizes on the land cover trajectories over the whole time series to highlight forest, cropland, grassland, bare area, urban area and water losses and gains. It provides for the first time a complete portrait of the Earth’s land surface transformations systematically described by the year of change and the land cover transition. At seasonal scale, vegetation phenology of tropical rainforest is prone to a large debate about the ability of remote sensing to monitor any vegetation cycle due to atmospheric contamination and more recently viewing and illumination geometry variation. Capitalizing on the 13-y reflectance values, this thesis proves that the seasonal dynamics of appropriate vegetation index are driven by leaf phenological events, themselves responding to light availability in order to enhance photosynthetic gain, in both Amazon and Congo basins.
Working Papers Working Papers Working Papers Working Papers Intermediation and Vertical Integration Intermediation and Vertical Integration

The views expressed in this paper do not necessarily represent those of the Federal Reserve Bank of Philadelphia or of the Federal Reserve System. Abstract Competition in retail and wholesale funding markets affect the incentive for originators (like investment banks) and fund managers (like mutual funds) to form integrated intermediaries (banks). Independent firms integrate both to produce higher yielding, illiquid assets and to suppress competition in retail markets. In addition to the higher return on illiquid assets, three factors increase the incentive to integrate. First, homogeneous savers lower the costs of producing illiquid assets and increase competition in retail markets. Second, fund managers' market power in wholesale markets increases competition in retail markets. Finally, more certain aggregate savings reduces the costs of producing illiquid assets.
Behavior Change Techniques Used to Promote Walking and Cycling

Objective: Evidence on the effectiveness of walking and cycling interventions is mixed. This may be partly attributable to differences in intervention content, such as the cognitive and behavioral techniques (BCTs) utilized. Adopting a taxonomy of BCTs, this systematic review addressed two questions: 1) What are the behavior change techniques used in walking and cycling interventions targeted at adults? 2) What characterizes interventions that appear to be associated with changes in walking and cycling in adults? Methods: Previous systematic reviews and updated database searches were used to identify controlled studies of individuallevel walking and cycling interventions involving adults. Characteristics of intervention design, context and methods were extracted in addition to outcomes. Intervention content was independently coded according to a 26-item taxonomy of BCTs. Results: Studies of forty six interventions met the inclusion criteria. Twenty-one reported a statistically significant effect on walking and cycling outcomes. Analysis revealed substantial heterogeneity in the vocabulary used to describe intervention content and the number of BCTs coded. ‘Prompt self-monitoring of behavior’ and ‘prompt intention formation’ were the most frequently coded BCTs. Conclusions: Future walking and cycling intervention studies should ensure that all aspects of the intervention are reported in detail. The findings lend support to the inclusion of self-monitoring and intention formation techniques in future walking and cycling intervention design, although further exploration of these and other BCTs is required. Further investigation of the interaction between BCTs and study design characteristics would also be

Implementation and Performance Analysis of Collaborative Peer-to-Peer Video-on-Demand Systems

Video-on-Demand (VoD) systems are of high popularity and responsible for generating large volumes of traffic in nowadays communication networks. The infrastructure of the VoD system providers needs to keep up with the increasing number of its user base and therefore it is important to find scalable and smart solutions that can adapt while maintaining a satisfactory performance. Basing VoD systems on peer-to-peer (P2P) technologies could distribute the burden of a network while optimizing, or at least maintaining, the performance during video playbacks. Content replicated and distributed by active users avoids the need for a huge number of dedicated servers. The usage of P2P for VoD also inherits some policies such as peer selection policy or piece selection policy that could be leveraged in a collaborative manner by entities such as Internet System Providers (ISP). ISPs usually try to safeguard networks with traffic shaping or load balancing. Bringing a collaborative interface could allow the ISPs to inform third party applications of certain overlay networks that should be respected, allowing the protection of some links or nodes from certain traffic. Achieving symbiosis between a P2P VoD service and ISPs may bring new opportunities to improve end user experience while guaranteeing the ISP best interests. In this context, this project aims to develop a P2P VoD prototype that allows to study the effectiveness of commonly used peer, piece, and replicas management/selection strategies, as well as the ability to implement new strategies. Additionally, it integrates the development of complementary P2P VoD systems monitoring strategies and collaborative mechanisms between the P2P VoD system and ISPs.
