The behaviour of the sea breeze along the north coast of Spain is investigated using observations of two topographically contrasting sites together with simulations from the Weather Research and Forecasting (WRF) model. An objective and systematic selection method is used to detect sea-breeze days from a database of two summer months. The direction and intensity of the sea breeze are significantly affected by the topography of the area; indeed, the estimated sea-breeze intensity shows an opposite relationship with the cross-shore temperature gradient for both sites. WRF simulations reproduce the onset of the sea breeze, but some characteristics are not adequately simulated: they generally overestimate the wind speed, smooth the temperature evolution and they do not represent the correct interaction with the terrain-induced flows. Additionally, four sensitivity experiments are performed with the WRF model varying the Planetary Boundary Layer (PBL) scheme, as well as the grid analysis nudging for an anomalous case study which is incorrectly filtered. As the two simulations considering nudging reproduce an unreal (not observed) sea breeze, this day turns out to be of great interest: it allows to evaluate the influence of the passage of the sea-breeze front (SBF) in other variables mainly related to turbulence. Furthermore, the best model scores are obtained for the PBL scheme that does not use a TKE closure.

The international ESCOMPTE campaign, which took place in summer 2001 in the most highly polluted French region, was devoted to validate air pollution prediction models. Surface and remote sensing instruments (Lidar, Radar and Sodar) were deployed over the Marseille area, along the Mediterranean coast, in order to investigate the fine structure of the sea-breeze circulation and its relationship with the pollutant concentrations. The geographical situation of the Marseille region combines a complex coastline and relief which both lead to a peculiar behaviour of the sea-breeze circulation. Several local sea breezes, perpendicular to the nearest coastline, settled in during the morning. In the afternoons, when the thermal gradient between the continental and marine surface grows up, a southerly or a westerly sea breeze may dominate. Their respective importance is then a function of time, space and altitude. Furthermore, an oscillation of the westerly sea breeze with a period of about 3 h is also highlighted. We show that these dynamical characteristics have profound influences on the atmospheric boundary-layer (ABL) development and on pollutant concentrations. In fact, the direction and intensity of the sea-breeze determine the route and the transit time of the stable marine air flow over the continental surface. Thus, the ABL depth may exhibit several collapses correlated with the westerly sea-breeze pulsation. The ozone and aerosol concentrations are also related to the dynamical features. In the suburbs and parts of the city under pulsed sea breezes, a higher ABL depth and higher ozone concentrations are observed. In the city centre, this relationship between pulsed sea-breeze intensity and ozone concentration is different, emphasising the importance of the transit time and also the build-up of pollutants in the marine air mass along the route. Finally, the variations of aerosol concentration are also described according to the breeze direction.

The behaviour and characteristics of the marine component of sea breeze cells have received little attention relative to their onshore counterparts. Yet there is a growing interest and dependence on the offshore wind climate from, for example, a wind energy perspective. Using idealized model experiments, we investigate the sea breeze circulation at scales which approximate to those of the southern North Sea, a region of major ongoing offshore wind farm development. We also contrast the scales and characteristics of the pure and the little known corkscrew and backdoor sea breeze types, where the type is pre-defined by the orientation of the synoptic scale flow relative to the shoreline. We find, crucially, that pure sea breezes, in contrast to corkscrew and backdoor types, can lead to substantial wind speed reductions offshore and that the addition of a second eastern coastline emphasises this effect through generation of offshore "calm zones". The offshore extent of all sea breeze types is found to be sensitive to both the influence of Coriolis acceleration and to the boundary layer scheme selected. These extents range, for example for a pure sea breeze produced in a 2 m s-1 offshore gradient wind, from 0 km to 21 km between the Mellor-Yamada-Nakanishi-Niino and the Yonsei State University schemes respectively. The corkscrew type restricts the development of a backdoor sea breeze on the opposite coast and is also capable of traversing a 100 km offshore domain even under high along-shore gradient wind speed (>15 m s-1) conditions. Realistic variations in sea surface skin temperature and initializing vertical thermodynamic profile do not significantly alter the resulting circulation, though the strengths of the simulated sea breezes are modulated if the effective land-sea thermal contrast is altered. We highlight how sea breeze impacts on circulation need to be considered in order to improve the accuracy of both assessments of the offshore wind energy climate and forecasts of wind energy output.

In the French Mediterranean basin the large city of Marseille and its industrialized suburbs (oil plants in the Fos-Berre area) are major pollutant sources that cause frequent and hazardous pollution episodes, especially in summer when intense solar heating enhances the photochemical activity and when the sea breeze circulation redistributes pollutants farther north in the countryside. This paper summarizes the findings of 5 years of research on the sea breeze in southern France and related mesoscale transport and dilution of pollutants within the Field Experiment to Constraint Models of Atmospheric Pollution and Emissions Transport (ESCOMPTE) program held in June and July 2001. This paper provides an overview of the experimental and numerical challenges identified before the ESCOMPTE field experiment and summarizes the key findings made in observation, simulation, and theory. We specifically address the role of large-scale atmospheric circulation to local ozone vertical distribution and the mesoscale processes driving horizontal advection of pollutants and vertical transport and mixing via entrainment at the top of the sea breeze or at the front and venting along the sloped terrain. The crucial importance of the interactions between processes of various spatial and temporal scales is thus highlighted. The advances in numerical modeling and forecasting of sea breeze events and ozone pollution episodes in southern France are also underlined. Finally, we conclude and point out some open research questions needing further investigation.

Field Observations of Swash-Zone Dynamics on a Sea-Breeze Dominated Beach at the Yucatán Peninsula, México

Sea breezes can modify the nearshore processes and alter beach morphology depending on the geographical location. Prior studies have shown that surf zone wave energy intensifies during strong sea-breeze conditions (wind speeds > 10 ms-1) and the impact on the coast can be similar to a small storm. However, few research efforts have investigated the coastal dynamics on sea-breeze dominated beaches (e.g., Masselink and Pattiaratchi, 1998, Mar. Geol.; Pattiaratchi et al., 1997, Cont. Shelf Res.) and, to the authors' knowledge, only one study has focused on swash-zone processes (Sonu et al., 1973, EOS). A field study was performed on a microtidal, low wave energy, sea-breeze dominated sandy beach in order to investigate the effects of local (sea breeze) and synoptic (storm) scale meteorological events on swash-zone dynamics. In-situ measurements of swash-zone hydrodynamics and sediment transport processes were collected from March 31st to April 12th, 2014 in Sisal, Yucatán located on the northern coast of the Yucatán Peninsula. Flow velocities and suspended sediment concentrations were measured concurrently, at multiple cross-shore and alongshore locations, using Vectrino-II profiling velocimeters and optical backscatter sensors, respectively. The high resolution data allowed the quantification of bed shear stress, turbulent dissipation rate, sediment loads and sediment flux during a mesoscale frontal system (cold-front passage referred to as an El Norte) and local sea-breeze cycles. Field observations showed that strong swash-zone bed shear stresses, turbulence intensity and sediment suspension occur during energetic conditions (i.e., El Norte event). On the other hand, despite milder energy conditions during the sea-breeze events, the alongshore component of bed-shear stresses and velocities can be significant owing to the high incidence wave angle associated with the sea-breeze system in the study area. The increased forcing in the swash zone induced sediment suspension, eroding the foreshore and causing accretion in the surf zone. The preliminary analysis demonstrates that strong sea-breeze events induce a significant alongshore swash-zone sediment transport that may be more important than that observed during an El Norte event.

The Influence of Soil Moisture, Coastline Curvature, and Land-Breeze Circulations on Sea-Breeze Initiated Precipitation

Idealized numerical simulations are performed with a coupled atmosphere/land-surface model to identify the roles of initial soil moisture, coastline curvature, and land breeze circulations on sea breeze initiated precipitation. Data collected on 27 July 1991 during the Convection and Precipitation Electrification Experiment (CAPE) in central Florida are used. The 3D Goddard Cumulus Ensemble (GCE) cloud resolving model is coupled with the Goddard Parameterization for Land-Atmosphere-Cloud Exchange (PLACE) land surface model, thus providing a tool to simulate more realistically land-surface/atmosphere interaction and convective initiation. Eight simulations are conducted with either straight or curved coast-lines, initially homogeneous soil moisture or initially variable soil moisture, and initially homogeneous horizontal winds or initially variable horizontal winds (land breezes). All model simulations capture the diurnal evolution and general distribution of sea-breeze initiated precipitation over central Florida. The distribution of initial soil moisture influences the timing, intensity and location of subsequent precipitation. Soil moisture acts as a moisture source for the atmosphere, increases the connectively available potential energy, and thus preferentially focuses heavy precipitation over existing wet soil. Strong soil moisture-induced mesoscale circulations are not evident in these simulations. Coastline curvature has a major impact on the timing and location of precipitation. Earlier low-level convergence occurs inland of convex coastlines, and subsequent precipitation occurs earlier in simulations with curved coastlines. The presence of initial land breezes alone has little impact on subsequent precipitation. however, simulations with both coastline curvature and initial land breezes produce significantly larger peak rain rates due to nonlinear interactions.

We complete the analysis of the data obtained during the experimental campaign around the semi circular bay of Quiberon, France, during two weeks in June 2006 (see Part 1). A reanalysis of numerical simulations performed with the Advanced Regional Prediction System model is presented. Three nested computational domains with increasing horizontal resolution down to 100 m, and a vertical resolution of 10 m at the lowest level, are used to reproduce the local-scale variations of the breeze close to the water surface of the bay. The Weather Research and Forecasting mesoscale model is used to assimilate the meteorological data. Comparisons of the simulations with the experimental data obtained at three sites reveal a good agreement of the flow over the bay and around the Quiberon peninsula during the daytime periods of sea-breeze development and weakening. In conditions of offshore synoptic flow, the simulations demonstrate that the semi-circular shape of the bay induces a corresponding circular shape in the offshore zones of stagnant flow preceding the sea-breeze onset, which move further offshore thereafter. The higher-resolution simulations are successful in reproducing the small-scale impacts of the peninsula and local coasts (breeze deviations, wakes, flow divergences), and in demonstrating the complexity of the breeze fields close to the surface over the bay. Our reanalysis also provides guidance for numerical simulation strategies for analyzing the structure and evolution of the near-surface breeze over a semi-circular bay, and for forecasting important flow details for use in upcoming sailing competitions.

A case study of sea breeze blocking regulated by sea surface temperature along the English south coast

NASA Astrophysics Data System (ADS)

Sweeney, J. K.; Chagnon, J. M.; Gray, S. L.

2013-09-01

The sensitivity of sea breeze structure to sea surface temperature (SST) and coastal orography is investigated in convection-permitting Met Office Unified Model simulations of a case study along the south coast of England. Changes in SST of 1 K are shown to significantly modify the structure of the sea breeze. On the day of the case study the sea breeze was partially blocked by coastal orography, particularly within Lyme Bay. The extent to which the flow is blocked depends strongly on the static stability of the marine boundary layer. In experiments with colder SST, the marine boundary layer is more stable, and the degree of blocking is more pronounced. The implications of prescribing fixed SST from climatology in numerical weather prediction model forecasts of the sea breeze are discussed.

In the Mediterranean basin, moisture transport can occur over large distance from remote regions by the synoptic circulation or more locally by sea breezes, driven by land-sea thermal contrast. Sea breezes play an important role in inland transport of moisture especially between late spring and early fall. In order to explicitly represent the two-way interactions at the atmosphere-ocean interface in the Mediterranean region and quantify the role of air-sea feedbacks on regional meteorology and climate, simulations at 20 km resolution performed with WRF regional climate model (RCM) and MORCE atmosphere-ocean regional climate model (AORCM) coupling WRF and NEMO-MED12 in the frame of HyMeX/MED-CORDEX are compared. One result of this study is that these simulations reproduce remarkably well the intensity, direction and inland penetration of the sea breeze and even the existence of the shallow sea breeze despite the overestimate of temperature over land in both simulations. The coupled simulation provides a more realistic representation of the evolution of the SST field at fine scale than the atmosphere-only one. Temperature and moisture anomalies are created in direct response to the SST anomaly and are advected by the sea breeze over land. However, the SST anomalies are not of sufficient magnitude to affect the large-scale sea-breeze circulation. The temperature anomalies are quickly damped by strong surface heating over land, whereas the water vapor mixing ratio anomalies are transported further inland. The inland limit of significance is imposed by the vertical dilution in a deeper continental boundary-layer.

The sea breeze is a great responsible for the organization of severe weather events, climate patterns and air pollution dispersion over the Metropolitan Area of São Paulo (MASP), being the knowledge about its correct predictability very important in the region. The Weather Research and Forecasting (WRF) mesoscale model was used to simulate some events of sea breeze propagation over the MASP during the winter season of 2009 (18th and 20th june, 29th august, 02nd September) with the objective to analyze the skill of the model on the predictability of this events using the default parameterizations available in the model and identify some flaws and possible adjustments to be made in the model. For this purpose, the simulation results were compared with the observed velocity and wind direction collected in the "Campo de Marte" Airport - SP. The model had a good response for all simulated days, where the horizontal wind and the vapor mixing ratio indicating correctly the sea breeze arrival over the region. Another important feature observed in the wind moisture fields was the moments that the sea breeze reaches different parts of MASP in response to the Urban Heat Island effect, which can accelerate or prevent the sea breeze propagation depending on location, as observed in other studies, and the relative position of the metropolitan area with respect to the sea-shore and the topography of the region. It was observed that the sea-breeze front reaches the southwest portion of MASP approximately two hours before it reaches the northwest portion.

Surface ozone (O3) was analyzed to investigate the role of the bay breeze on air quality at two locations in Edgewood, Maryland (lat: 39.4deg, lon: -76.3deg) for the month of July 2011. Measurements were taken as part of the first year of NASA's "Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality" (DISCOVER-AQ) Earth Venture campaign and as part of NASA's Geostationary for Coastal and Air Pollution Events Chesapeake Bay Oceanographic campaign with DISCOVER-AQ (Geo-CAPE CBODAQ). Geo-CAPE CBODAQ complements DISCOVER-AQ by providing ship-based observations over the Chesapeake Bay. A major goal of DISCOVER-AQ is determining the relative roles of sources, photochemistry and local meteorology during air quality events in the Mid-Atlantic region of the U.S. Surface characteristics, transport and vertical structures of O3 during bay breezes were identified using in-situ surface, balloon and aircraft data, along with remote sensing equipment. Localized late day peaks in O3 were observed during bay breeze days, maximizing an average of 3 h later compared to days without bay breezes. Of the 10 days of July 2011 that violated the U.S. Environmental Protection Agency (EPA) 8 h O3 standard of 75 parts per billion by volume (ppbv) at Edgewood, eight exhibited evidence of a bay breeze circulation. The results indicate that while bay breezes and the processes associated with them are not necessary to cause exceedances in this area, bay breezes exacerbate poor air quality that sustains into the late evening hours at Edgewood. The vertical and horizontal distributions of O3 from the coastal Edgewood area to the bay also show large gradients that are often determined by boundary layer stability. Thus, developing air quality models that can sufficiently resolve these dynamics and associated chemistry, along with more consistent monitoring of O3 and meteorology on and along the complex coastline of Chesapeake Bay must be a high priority.

The main agricultural areas in South Florida are located within the fertile land surrounding Lake Okeechobee. The Atlantic Watershed monthly rainfall anomalies showed a weak but statistically significant correlation to the Oceanic Nino Index (ONI). No other watershed s anomalies showed significant correlations with ONI or the Southern Oscillation Index (SOI). During La Nina months, less sea breeze days and more disturbed days were found to occur compared to El Nino and neutral months. The increase in disturbed days can likely by attributed to the synoptic pattern during La Nina, which is known to be favorable for tropical systems to follow paths that affect South Florida. Overall, neither sea breeze rainfall patterns nor total rainfall patterns in South Florida s main agricultural areas were found to be strongly influenced by the El Nino Southern Oscillation during our study time.

Investigation on the fine structure of sea-breeze during ESCOMPTE experiment

2005-03-01

Surface and remote-sensing instruments deployed during ESCOMPTE experiment over the Marseille area, along the Mediterranean coast, were used to investigate the fine structure of the atmospheric boundary layer (ABL) during sea-breeze circulation in relation to pollutant transport and diffusion. Six sea-breeze events are analyzed with a particular focus on 25 June 2001. Advection of cool and humid marine air over land has a profound influence on the daytime ABL characteristics. This impact decreases rapidly with the inland distance from the sea. Nearby the coast (3 km inland), the mixing height Zi rises up to 750 m and falls down after 15:00 (UT) when the breeze flow reaches its maximum intensity. A more classical evolution of the ABL is observed at only 11-km inland where Zi culminates in the morning and stabilizes in the afternoon at about 1000 m height. Fine inspection of the data revealed an oscillation of the sea-breeze with a period about 2 h 47 min. This feature, clearly discernable for 3 days at least, is present in several atmospheric variables such as wind, temperature, not only at the ground but also aloft in the ABL as observed by sodar/RASS and UHF wind profilers. In particular, the mixing height Zi deduced from UHF profilers observations is affected also by the same periodicity. This pulsated sea-breeze is observed principally above Marseille and, at the northern and eastern shores of the Berre pond. In summary, the periodic intrusion over land of cool marine air modifies the structure of the ABL in the vicinity of the coast from the point of view of stability, turbulent motions and pollutants concentration. An explanation of the source of this pulsated sea-breeze is suggested.

Examining the eastern Amazon Basin breeze circulations, channeling and boundary layer properties using altitude controlled meteorological balloons

During the period August 24-28, 2016, in a delayed component the GO-Amazon Project, we launched nine altitude-controlled free balloons (CMET). Smaller than typical rawinsondes, CMET are equipped with altitude control, global communication via Iridium satellite, and aspirated sensors. The aims of our effort were to examine the interactions among convective boundary layer and dual river breeze circulations near the confluence of the Tapajos and Amazon Rivers in the eastern Basin. The week-long field campaign was timed to examine the reestablishment of the breeze circulations shortly after the passage of a strong instability line on August 22. Nine CMET were launched at the Curua-Una hydroelectric dam (2.8S; 54.3W), timed to encounter the Tapajos river breeze front by late afternoon. Soundings were made to establish the thickness of interface between the easterly trade and westerly Tapajos breeze circulation. Careful use of sounding strategies allowed these free balloons to track along the northerly channeled flow in the lowest 300 m above the River. Following the river encounter, balloons tracked to the west, sounding to describe the diurnal course of boundary layer in the forest west of the Tapajos River. The longest flight traveled more than 770 km over three days and twice rested overnight in the rain forest canopy. Ancillary data from surface climate and flux stations as well as the Santarem radiosonde, satellite images will be used to illustrate how the breeze circulations are seen near the surface and how they were disrupted by larger-scale events. Comparisons with HYSPLIT trajectories will illustrate how sensitive real trajectories are to the refraction that the encounter with the breeze effects.

A study of the Merritt Island, Florida sea breeze flow regimes and their effect on surface heat and moisture fluxes

1993-01-01

Data collected during the Convective and Precipitation/Electrification Experiment were analyzed as part of an investigation of the sea breeze in the vicinity of Merritt Island, Florida. Analysis of near-surface divergence fields shows that the classical 24-hour oscillation in divergence over the island due to the direct sea breeze circulation is frequently disrupted and exhibits two distinct modes: the classical sea breeze pattern and deviations from that pattern. A comparison of clear day surface energy fluxes with fluxes on other days indicates that changes in magnitudes were dominated by the presence or absence of clouds. Non-classical sea breeze days tended to lose more available energy in the morning than classical sea breeze days due to earlier development of small cumulus over the island. A composite storm of surface winds, surface energy fluxes, rainfall, and satellite visible data was constructed. A spectral transmittance over the visible wavelengths for the cloud cover resulting from the composite storm was calculated. It is shown that pre-storm transmittances of 0.8 fall to values near 0.1 as the downdraft moves directly over the site. It is also found that under post-composite storm conditions of continuous clear sky days, 3.5 days are required to evaporate back into the atmosphere the latent heat energy lost to the surface by rainfall.

A case study of sea breeze blocking regulated by sea surface temperature along the English south coast

Sweeney, J. K.; Chagnon, J. M.; Gray, S. L.

2014-05-01

The sensitivity of sea breeze structure to sea surface temperature (SST) and coastal orography is investigated in convection-permitting Met Office Unified Model simulations of a case study along the south coast of England. Changes in SST of 1 K are shown to significantly modify the structure of the sea breeze immediately offshore. On the day of the case study, the sea breeze was partially blocked by coastal orography, particularly within Lyme Bay. The extent to which the flow is blocked depends strongly on the static stability of the marine boundary layer. In experiments with colder SST, the marine boundary layer is more stable, and the degree of blocking is more pronounced. Although a colder SST would also imply a larger land-sea temperature contrast and hence a stronger onshore wind - an effect which alone would discourage blocking - the increased static stability exerts a dominant control over whether blocking takes place. The implications of prescribing fixed SST from climatology in numerical weather prediction model forecasts of the sea breeze are discussed.

The Sea Breeze in South-Iceland: Observations with an unmanned aircraft and numerical simulations

2010-05-01

Sea breeze events, 19-20 July 2009, observed during the international field campaign MOSO, at the southcoast of Iceland, have been investigated using high resolution numerical simulations. Thanks to the use of a small unmanned aircraft system (UAS), SUMO, the wind and temperature aloft could be observed at a high resolution in both space and time. Simultaneously with the UAS operations, conventional platforms were used to obtain surface measurements. The observations show a distinct sea breeze circulation with an onset at around noon and a final decay around 19:00 UTC. At the maximum, the sea breeze layer reached a height of appr. 400 m, marked by a capping wind minimum. When compared to the flow aloft, the sea breeze layer was found to exhibit relatively low temperatures and an expected turn from an off-shore to an on-shore flow. Overall, the agreement between the observations and simulations are relatively good. The simulations suggest a horizontal extent of the circulation some 20-30 km off-shore, but only around 5 km on-shore.

Possible impacts of the pre-monsoon dry line and sea breeze front on nocturnal rainfall over northeast Bangladesh

NASA Astrophysics Data System (ADS)

Stiller-Reeve, Mathew; Toniazzo, Thomas; Kolstad, Erik; Spengler, Thomas

2017-04-01

The northeast region of Bangladesh receives a large amount of rainfall before the large-scale monsoon circulation begins. For example, in April (a "pre-monsoon" month) 2010, 804 mm of rain fell in the regional capital Sylhet. It was the second wettest month of the entire year. From our conversations with the local people, we know that this pre-monsoon rainfall is extremely important to their livelihoods. We therefore need to understand it's triggering mechanisms. Several theories have been published, all of which are likely to be at play. However, in this work we look more closely at how the sea breeze front and prominent pre-monsoonal dry line in this region may play a role. If these mechanisms play a role in the convection, then it is likely that they trigger convection further afield, and then the resulting systems then propagate towards northeast Bangladesh. We believe this because rainfall associated with dry line/sea-breeze front convection often occurs during the late afternoon, but the rainfall over northeast Bangladesh shows a clear late-night/early-morning maxima. At present, the temporal and spatial resolution of the regional observations is inappropriate for examining these possible mechanisms. We therefore use a numerical model (WRF) to investigate the possible links between the convection and the sea breeze front and dry line. We use April 2010 as a case study since it was such a wet pre-monsoon month. The simulation shows that a sea breeze circulation often develops during the day in the coastal zone of Bangladesh and northeast India. After sunset the sea breeze front propagates inland pushing back the hot, dry air over India. On several days during the simulation, convection is triggered along the sea breeze front, which then propagates towards northeast Bangladesh and intensifies across the topography surrounding the Sylhet region. From our simulations, it appears that nocturnal convection over northeast Bangladesh is triggered by several mechanisms, but that the dry line and sea breeze front could also be an active contributor.

Orographic fog occurrences associated with sea breezes determine water collection potential over the mountain ranges near the Mediterranean coast of the Iberian Peninsula. Previous works have confirmed that the effect of sea breezes on cloud genera is to increase the frequency of low (Stratus) and convective (Cumulus) clouds. The primary impact of sea breeze flows corresponds to low stratiform clouds (Stratus, St, and Stratocumulus, Sc) formed in the convective internal boundary layer due to the inflow of moist sea air at lower levels. The formation of Sc clouds is caused by the rising and cooling of turbulent moist sea air over the highest slopes of the mountains at the end of the day. In the most Sc formation, we also observed dense fog banks of Stratus nebulosus (St neb) and dew during the early next morning, covering the inland topographical depressions. The aim of this study is to statistically analyze the impact of sea breezes on fog water collection in the convective internal boundary layer. The study area is located in the eastern of the Iberian Peninsula (Valencia region, Spain) and the survey corresponds to a 7-yr study period (2003-2009). This research is based upon a small network of eight passive fog water collectors distributed over 6 coastal- and 2 inland-mountain areas. A cylindrical fog water instrument (i.e. omnidirectional collection efficiency) based on the ASRC (Atmospheric Science Research Centre, State University of New York) string collector is used to sample fog water volumes on a daily basis. These stations also sampled temperature, humidity, wind speed and direction and precipitation measurements. The current study used these meteorological measurements to apply an automated and manual selection methodologies for identifying past sea breeze episodes. The dataset created by means of these selection techniques allows for the study of fog water volumes associated with sea breeze situations. A detailed statistical characterization of the orographic clouds episodes associated with sea breezes and other interesting aspects of this fog water collection study are presented here.

Surface ozone (O 3 ) was analyzed to investigate the role of the bay breeze on air quality at two locations in Edgewood, Maryland (lat: 39.4°, lon: -76.3°) for the month of July 2011. Measurements were taken as part of the first year of NASA's "Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality" (DISCOVER-AQ) Earth Venture campaign and as part of NASA's Geostationary for Coastal and Air Pollution Events Chesapeake Bay Oceanographic campaign with DISCOVER-AQ (Geo-CAPE CBODAQ). Geo-CAPE CBODAQ complements DISCOVER-AQ by providing ship-based observations over the Chesapeake Bay. A major goal of DISCOVER-AQ is determining the relative roles of sources, photochemistry and local meteorology during air quality events in the Mid-Atlantic region of the U.S. Surface characteristics, transport and vertical structures of O 3 during bay breezes were identified using in-situ surface, balloon and aircraft data, along with remote sensing equipment. Localized late day peaks in O 3 were observed during bay breeze days, maximizing an average of 3 h later compared to days without bay breezes. Of the 10 days of July 2011 that violated the U.S. Environmental Protection Agency (EPA) 8 h O 3 standard of 75 parts per billion by volume (ppbv) at Edgewood, eight exhibited evidence of a bay breeze circulation. The results indicate that while bay breezes and the processes associated with them are not necessary to cause exceedances in this area, bay breezes exacerbate poor air quality that sustains into the late evening hours at Edgewood. The vertical and horizontal distributions of O 3 from the coastal Edgewood area to the bay also show large gradients that are often determined by boundary layer stability. Thus, developing air quality models that can sufficiently resolve these dynamics and associated chemistry, along with more consistent monitoring of O 3 and meteorology on and along the complex coastline of Chesapeake Bay must be a high priority.

The impact of land and sea surface variations on the Delaware sea breeze at local scales

NASA Astrophysics Data System (ADS)

Hughes, Christopher P.

The summertime climate of coastal Delaware is greatly influenced by the intensity, frequency, and location of the local sea breeze circulation. Sea breeze induced changes in temperature, humidity, wind speed, and precipitation influence many aspects of Delaware's economy by affecting tourism, farming, air pollution density, energy usage, and the strength, and persistence of Delaware's wind resource. The sea breeze front can develop offshore or along the coastline and often creates a near surface thermal gradient in excess of 5°C. The purpose of this dissertation is to investigate the dynamics of the Delaware sea breeze with a focus on the immediate coastline using observed and modeled components, both at high resolutions (~200m). The Weather Research and Forecasting model (version 3.5) was employed over southern Delaware with 5 domains (4 levels of nesting), with resolutions ranging from 18km to 222m, for June 2013 to investigate the sensitivity of the sea breeze to land and sea surface variations. The land surface was modified in the model to improve the resolution, which led to the addition of land surface along the coastline and accounted for recent urban development. Nine-day composites of satellite sea surface temperatures were ingested into the model and an in-house SST forcing dataset was developed to account for spatial SST variation within the inland bays. Simulations, which include the modified land surface, introduce a distinct secondary atmospheric circulation across the coastline of Rehoboth Bay when synoptic offshore wind flow is weak. Model runs using high spatial- and temporal-resolution satellite sea surface temperatures over the ocean indicate that the sea breeze landfall time is sensitive to the SST when the circulation develops offshore. During the summer of 2013 a field campaign was conducted in the coastal locations of Rehoboth Beach, DE and Cape Henlopen, DE. At each location, a series of eleven small, autonomous thermo-sensors (i-buttons) were placed along 1-km transects oriented perpendicular to the coastline where each sensor recorded temperatures at five-minute intervals. This novel approach allows for detailed characterization of the sea breeze front development over the immediate coastline not seen in previous studies. These observations provide evidence of significant variability in frontal propagation (advancing, stalling, and retrograding) within the first kilometer of the coast. Results from this observational study indicate that the land surface has the largest effect on the frontal location when the synoptic winds have a strong offshore component, which forces the sea breeze front to move slowly through the region. When this happens, the frequency of occurrence and sea breeze frontal speed decreases consistently across the first 500 m of Rehoboth Beach, after which, the differences become insignificant. At Cape Henlopen the decrease in intensity across the transect is much less evident and the reduction in frequency does not occur until after the front is 500 m from the coast. Under these conditions at Rehoboth Beach, the near surface air behind the front warms due to the land surface which, along with the large surface friction component of the urbanized land surface, causes the front to slow as it traverses the region. Observation and modeling results suggest that the influence of variations in the land and sea surface on the sea breeze circulation is complex and highly dependent on the regional synoptic wind regime. This result inspired the development of a sea breeze prediction algorithm using a generalized linear regression model which, incorporated real-time synoptic conditions to forecast the likelihood of a sea breeze front passing through a coastal station. The forecast skill increases through the morning hours after sunrise. The inland synoptic wind direction is the most influential variable utilized by the algorithm. Such a model could be enhanced to forecast local temperature with coonfidence, which could be useful in an economic or energy usage model.

Sea breezes and advective effects in southwest James Bay

Mckendry, Ian; Roulet, Nigel

1994-01-01

Observations from a transect extending 100 km inland during the Northern Wetlands Study (NOWES) in 1990 show that the sea breeze develops on approximately 25% of days during summer and may penetrate up to 100 km inland on occasions. The sea breeze exhibits a marked diurnal clockwise rotation as a result of the Coriolis effect along the unobstructed coastline. The marine advective effect is shown to depend on gradient wind direction. With northwesterly upper level flow the sea breeze tends to be northeasterly in direction and is associated with decreased temperatures and vapor pressure deficits (VPD). With southwesterly upper level flow the sea breeze tends to have a southeasterly direction and less effect on temperatures and VPD. This is attributed to shorter residence times of air parcels over water. For two cases, Colorado State University mesoscale model simulations show good agreement with surface wind observations and suggest that under northwesterly gradient flow, Bowen ratios are increased in the onshore flow along western James Bay, while during southwesterly gradient flow these effects are negligible. These results have implications for the interpretation of local climate, ecology, and hydrology as well as land-based and airborne turbulent flux measurements made during NOWES.

The inland boundary layer at low latitudes: II Sea-breeze influences

1985-11-01

Two-dimensional mesoscale model results support the claim of evening sea-breeze activity at Daly Waters, 280 km inland from the coast in northern Australia, the site of the Koorin boundary-layer experiment. The sea breeze occurs in conditions of strong onshore and alongshore geostrophic winds, not normally associated with such activity. It manifests itself at Daly Waters and in the model as a cooling in a layer 500 1000 m deep, as an associated surface pressure jump, as strong backing of the wind and, when an offshore low-level wind is present, as a collapse in the inland nocturnal jet. Both observational analysis and model results illustrate the rotational aspects of the deeply penetrating sea breeze; in our analysis this is represented in terms of a surge vector — the vector difference between the post- and pre-frontal low-level winds. There is further evidence to support earlier work that the sea breeze during the afternoon and well into the night — at least for these low-latitude experiments — behaves in many ways as an atmospheric gravity current, and that inland penetrations up to 500 km occur.

Vertical Structure of the Urban Boundary Layer over Marseille Under Sea-Breeze Conditions

Lemonsu, Aude; Bastin, Sophie; Masson, Valéry; Drobinski, Philippe

2006-03-01

During the UBL-ESCOMPTE program (June July 2001), intensive observations were performed in Marseille (France). In particular, a Doppler lidar, located in the north of the city, provided radial velocity measurements on a 6-km radius area in the lowest 3 km of the troposphere. Thus, it is well adapted to document the vertical structure of the atmosphere above complex terrain, notably in Marseille, which is bordered by the Mediterranean sea and framed by numerous massifs. The present study focuses on the last day of the intensive observation period 2 (26 June 2001), which is characterized by a weak synoptic pressure gradient favouring the development of thermal circulations. Under such conditions, a complex stratification of the atmosphere is observed. Three-dimensional numerical simulations, with the Méso-NH atmospheric model including the town energy balance (TEB) urban parameterization, are conducted over south-eastern France. A complete evaluation of the model outputs was already performed at both regional and city scales. Here, the 250-m resolution outputs describing the vertical structure of the atmosphere above the Marseille area are compared to the Doppler lidar data, for which the spatial resolution is comparable. This joint analysis underscores the consistency between the atmospheric boundary layer (ABL) observed by the Doppler lidar and that modelled by Méso-NH. The observations and simulations reveal the presence of a shallow sea breeze (SSB) superimposed on a deep sea breeze (DSB) above Marseille during daytime. Because of the step-like shape of the Marseille coastline, the SSB is organized in two branches of different directions, which converge above the city centre. The analysis of the 250-m wind fields shows evidence of the role of the local topography on the local dynamics. Indeed, the topography tends to reinforce the SSB while it weakens the DSB. The ABL is directly affected by the different sea-breeze circulations, while the urban effects appear to be negligible.

A numerical study of the effects of a large sandbar upon sea breeze development

NASA Technical Reports Server (NTRS)

Kessler, R. C.; Pielke, R. A.; Mcqueen, J.; Eppel, D.

1985-01-01

Two-dimensional numerical simulations of sea breeze development over a large sandbar on the North Sea coast of Germany are reported. The numerical model used in these experiments contains a detailed treatment of soil moisture, which allows evaluation of the effects of differential surface characteristics on the airflow pattern. Results of the simulations indicate that the contrast between the moist sandbar and adjacent dry land, the tidal inundation of the sandbar, and the westward penetration of the Baltic sea breeze play important roles in the development of mesoscale airflow patterns in the sandbar region.

Land- and sea-surface impacts on local coastal breezes

The state of Delaware has seen significant increases in population along the coastline in the past three decades. With this increase in population have come changes to the land surface, as forest and farmland has been converted to residential and commercial purposes, causing changes in the surface roughness, temperature, and land-atmosphere fluxes. There is also a semi-permanent upwelling center in the spring and summer outside the Delaware Bay mouth that significantly changes the structure of the sea surface temperature both inside and outside the Bay. Through a series of high resolution modeling and observational studies, we have determined that in cases of strong synoptic forcing, the impact of the land-surface on the boundary layer properties can be advected offshore, creating a false coastline and modifying the location and timing of the sea breeze circulation. In cases of weak synoptic forcing, the influence of the upwelling and the tidal circulation of the Delaware Bay waters can greatly change the location, strength, and penetration of the sea breeze. Understanding the importance of local variability in the surface-atmosphere interactions on the sea breeze can lead to improved prediction of sea breeze onset, penetration, and duration which is important for monitoring air quality and developing offshore wind power production.

Rapid development has led to frequent haze in Beijing. With mountains and sea surrounding Beijing, the pollution is found to be influenced by the mountain-plain breeze and sea-land breeze in complex ways. Meanwhile, the presence of aerosols may affect the surface energy balance and impact these boundary layer (BL) processes. The effects of BL processes on aerosol pollution and the feedback between aerosol and BL processes are not yet clearly understood. Thus, the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem) is used to investigate the possible effects and feedbacks during a haze episode on 23 September 2011. Influenced by the onshore prevailing wind, sea-breeze, and upslope breeze, about 45% of surface particulate matter (PM)2.5 in Beijing are found to be contributed by its neighbor cities through regional transport. In the afternoon, the development of upslope breeze suppresses the growth of BL in Beijing by imposing a relatively low thermal stable layer above the BL, which exacerbates the pollution. Two kinds of feedback during the daytime are revealed as follows: (1) as the aerosols absorb and scatter the solar radiation, the surface net radiation and sensible heat flux are decreased, while BL temperature is increased, resulting in a more stable and shallower BL, which leads to a higher surface PM2.5 concentration in the morning and (2) in the afternoon, as the presence of aerosols increases the BL temperature over plains, the upslope breeze is weakened, and the boundary layer height (BLH) over Beijing is heightened, resulting in the decrease of the surface PM2.5 concentration there.

Chemical composition, microphysical, and optical properties of atmospheric aerosol deep inland in the Negev Desert of Israel are found to be influenced by daily occurrences of sea breeze flow from the Mediterranean Sea. Abrupt increases in aerosol volume concentration and shifts of size distributions towards larger sizes, which are associated with increase in wind speed and atmospheric water content, were systematically recorded during the summertime at a distance of at least 80 km from the coast. Chemical imaging of aerosol samples showed an increased contribution of highly hygroscopic particles during the intrusion of the sea breeze. Besides a significant fraction of marine aerosols, the amount of internally mixed marine and mineral dust particles was also increased during the sea breeze period. The number fraction of marine and internally mixed particles during the sea breeze reached up to 88 % in the PM1-2. 5 and up to 62 % in the PM2. 5-10 size range. Additionally, numerous particles with residuals of liquid coating were observed by SEM/EDX analysis. Ca-rich dust particles that had reacted with anthropogenic nitrates were evidenced by Raman microspectroscopy. The resulting hygroscopic particles can deliquesce at very low relative humidity. Our observations suggest that aerosol hygroscopic growth in the Negev Desert is induced by the daily sea breeze arrival. The varying aerosol microphysical and optical characteristics perturb the solar and thermal infrared radiations. The changes in aerosol properties induced by the sea breeze, relative to the background situation, doubled the shortwave radiative cooling at the surface (from -10 to -20.5 W m-2) and increased by almost 3 times the warming of the atmosphere (from 5 to 14 W m-2), as evaluated for a case study. Given the important value of observed liquid coating of particles, we also examined the possible influence of the particle homogeneity assumption on the retrieval of aerosol microphysical characteristics. The tests suggest that sensitivity to the coating appears if backward scattering and polarimetric measurements are available for the inversion algorithm. This may have an important implication for retrievals of aerosol microphysical properties in remote sensing applications.

The Quiberon 2006 experiment was launched to document the onset and development of land and sea breezes over a semi-circular coastal bay propitious to inshore sailing competitions. The measurements were taken during the 2 weeks of 16-28 June 2006. Micrometeorological variables were recorded at three shore sites around the bay using turbulence sensors on 10-30-m high masts, on four instrumented catamarans at selected sites within the bay, and at a fourth shore site with a Sodar. Synoptic data and local measurements are analyzed here from the point of view of both micrometeorologists and competition skippers, testing in particular the empirical rules of breeze veering and backing according to the wind direction with respect to the coastline orientation at the mesoscale (the quadrant theory). Our analysis focuses on the patterns of lower-altitude wind direction and speed around the bay and over the water basin, and the temporal variations during the periods of the breeze onset, establishment and thermal reinforcement. In offshore synoptic-flow conditions (quadrants 1 and 2), the clockwise rotation of the surface flow had a very large amplitude, reaching up to 360°. The breeze strength was negatively correlated to that of the synoptic wind speed. In conditions of onshore synoptic flow from the west (quadrant 3) at an angle to the mainland coast but perpendicular to the Quiberon peninsula, the rotation of the flow was backwards in the early morning and clockwise during the day with a moderate amplitude (40°-50°) around the synoptic wind direction. As the surface wind speed was much larger than the synoptic wind speed, such a case we have designated as a "synoptic breeze". The breeze onset was shown to fail several times under the influence of weak non-thermal events, e.g., the passage of an occluded front or clouds or an excess of convection. Finally, several local-scale influences of the complex coastal shape appeared in our measurements, e.g., wind fanning in the lee of the isthmus and airflow skirting around the peninsula forehand.

Global Positioning System (GPS) tomography analyses of water vapor, complemented by high-resolution numerical simulations are used to investigate a Mistral/sea breeze event in the region of Marseille, France, during the ESCOMPTE experiment. This is the first time GPS tomography has been used to validate the three-dimensional water vapor concentration from numerical simulation, and to analyze a small-scale meteorological event. The high spatial and temporal resolution of GPS analyses provides a unique insight into the evolution of the vertical and horizontal distribution of water vapor during the Mistral/sea-breeze transition.

Located close to the sea indicates that there are influences of the sea-land breeze circulation on the weather condition in Deli Serdang. The purpose of this study is to simulate sea-land breeze occurrence and its influence on the convective activities in Deli Serdang. The research area covers the area of Deli Serdang Regency and the surrounding ocean region in the coordinates 02°57‧-03°16‧N & 98°33‧-99°27‧E where Kualanamu Meteorological Station is the centre of the research area at coordinate 03°34‧N & 98°44‧E and the elevation about 27MAMSL. The research time is a day with the highest rainfall in the highest peak rainy month. The raw data consist of the Himawari-8 satellite image from BMKG, FNL (Final Analysis) data from http://rda.ucar.edu, and meteorological observation data from Kualanamu Meteorology Station. This study indicates that WRF-ARW can simulate the sea-land breeze occurrence on the coast of Deli Serdang well. The existence of the convective index cover in the convergence area proves the sea-land breeze occurred in the coast of Deli Serdang can form the convergence area as the interacted result with the wind from other directions that support convective activities.

Impacts of the land-lake breeze of the Volta reservoir on the diurnal cycle of cloudiness and precipitation

Lake Volta in Ghana is the artificial lake on Earth with the largest surface area (8502 km2). It has been constructed in the early 1960s, with the lake being filled around 1966. Land-lake breezes and their effects on the diurnal cycle of local wind systems, cloudiness, and precipitation have been studied for several tropical lakes, among which studies on the effects of Lake Victoria in East Africa are one of the most perceived ones. To date, no studies on the strengths and effects of the land-lake breeze of the Volta reservoir are known to the authors. Using surface station data, a variety of satellite data on clouds and precipitation, and a convection-resolving regional model, the land-lake breeze and its impacts were studied for Lake Volta between 1998 and 2015. The observational data sets confirm a significant land-lake circulation. The only manned weather station operated by the Ghana Meteorological Service that is situated at the lake is Kete Krachi. Hourly observations for 2006 and 2014 show on several days a clearing of skies in the afternoon associated with a shift in the surface winds from southwest to southeast, the latter potentially indicating a lake breeze effect. Cloud occurrence frequency derived from the CLARA-A2, MODIS, and CLAAS2 cloud masks and the cloud physical properties from CLAAS2 clearly show the development of clouds at the lake breeze front in the course of the morning and around mid-day. This effect is most pronounced in March when also the difference between the surface temperatures of the lake and the desiccated land surface is strongest. During the peak of the wet season in July, the lake breeze cloudiness is masked by a high background cloudiness and likely also weaker due to the strong southwesterly monsoon flow that tends to weaken the land-lake circulation. However, the precipitation signal was found to be strongest in July, most probably due to the fact that in boreal fall, winter and spring, the lake breeze cloudiness often fails to develop into afternoon showers or thunderstorms, or if, they are short-lived with substantial below-cloud evaporation. Two cases in 2007 and 2014 were synoptically analyzed with weather charts and modeled using the COSMO model, the current regional operational weather forecasting model of the German Weather Service (DWD). The COSMO experiments with and without the lake were integrated for 48 hours at convection-resolving resolution of 2.8 km. Initial and boundary conditions were taken from ECWMF operational analysis. Model results confirm the development of the daytime lake breeze and suggest that the existence of the lake has substantially changed the local circulation, cloudiness and precipitation regime. Our results imply a significant impact of the artificial lake on the local climate and ecosystems that warrants further study.

Evaluation of the 29-km Eta Model for Weather Support to the United States Space Program

NASA Technical Reports Server (NTRS)

Manobianco, John; Nutter, Paul

1997-01-01

The Applied Meteorology Unit (AMU) conducted a year-long evaluation of NCEP's 29-km mesoscale Eta (meso-eta) weather prediction model in order to identify added value to forecast operations in support of the United States space program. The evaluation was stratified over warm and cool seasons and considered both objective and subjective verification methodologies. Objective verification results generally indicate that meso-eta model point forecasts at selected stations exhibit minimal error growth in terms of RMS errors and are reasonably unbiased. Conversely, results from the subjective verification demonstrate that model forecasts of developing weather events such as thunderstorms, sea breezes, and cold fronts, are not always as accurate as implied by the seasonal error statistics. Sea-breeze case studies reveal that the model generates a dynamically-consistent thermally direct circulation over the Florida peninsula, although at a larger scale than observed. Thunderstorm verification reveals that the meso-eta model is capable of predicting areas of organized convection, particularly during the late afternoon hours but is not capable of forecasting individual thunderstorms. Verification of cold fronts during the cool season reveals that the model is capable of forecasting a majority of cold frontal passages through east central Florida to within +1-h of observed frontal passage.

Soil Moisture, Coastline Curvature, and Sea Breeze Initiated Precipitation Over Florida

Land surface-atmosphere interaction plays a key role in the development of summertime convection and precipitation over the Florida peninsula. Land-ocean temperature contrasts induce sea-breeze circulations along both coasts. Clouds develop along sea-breeze fronts, and significant precipitation can occur during the summer months. However, other factors such as soil moisture distribution and coastline curvature may modulate the timing, location, and intensity of sea breeze initiated precipitation. Here, we investigate the role of soil moisture and coastline curvature on Florida precipitation using the 3-D Goddard Cumulus Ensemble (GCE) cloud model coupled with the Parameterization for Land-Atmosphere-Cloud Exchange (PLACE) land surface model. This study utilizes data from the Convection and Precipitation Electrification Experiment (CaPE) collected on 27 July 1991. Our numerical simulations suggest that a realistic distribution of soil moisture influences the location and intensity of precipitation but not the timing of precipitation. In contrast, coastline curvature affects the timing and location of precipitation but has little influence on peak rainfall rates. However, both factors (soil moisture and coastline curvature) are required to fully account for observed rainfall amounts.

To better understand the diurnal cycle of the Sea-Breeze (SB) in the island of Mallorca, during September 2013 the Mallorca Sea Breeze experimental field campaign (MSB13) took place in the Campos basin (located in the south side of the island). Measurements in the lower boundary layer (captive balloon and multicopter) and close to the surface were taken in a site close to the coast (500m inland). In this work an observed morning transition of the SB is further analysed through the observations and a high-resolution mesoscale simulation of this selected case. With the combined inspection of model results and observations, it is found that during the night-time the air flows out of the island: a land-breeze is found near the coast and downslope winds at the mountain slopes. After sunrise and during the previous phase (0600-0800 UTC) the temperature difference between land and sea is reduced meanwhile the wind has the land-breeze direction. During the preparatory phase (0800-1000 UTC) the land surface temperature is warmer than the sea and the wind weakens and veers towards the SB direction. Finally, during the development phase (1000-1200 UTC) the SB front propagates through the center of the Campos basin to the end of the basin, enhanced by the mountain upslope winds. Therefore, the radiative warming stops. The temperature, momentum and TKE budgets are used to understand the most relevant physical processes involved in each of the phases.

Partitioning between the relative effects of the radiative and aerodynamic components of the atmospheric forcing on evaporation is challenging since diurnal distributions of wind speed and solar radiation typically overlap. The Dead Sea is located about a 100 km off the Eastern Mediterranean coast, where and the Mediterranean Sea breeze front reaches it after sunset. Therefore, in the Dead Sea the peaks of solar radiation and wind speed diurnal cycles in the Dead Sea are distinctly separated in time, offering a unique opportunity to distinguish between their relative impacts on evaporation. We present mid-summer eddy covariance and meteorological measurements of evaporation rate and surface energy fluxes over the Dead Sea. The evaporation rate is characterized by a clear diurnal cycle with a daytime peak, few hours after solar radiation peak, and a nighttime peak coincident with wind speed peak. Evaporation rate is minimum during sunrise and sunset. Measurements of evaporation rate from two other water bodies that are closer to the Mediterranean coast, Eshkol Reservoir, and Lake Kinneret, present a single afternoon peak, synchronous with the sea breeze. The inland diurnal evaporation rate cycle varies with the distance from the Mediterranean coast, following the propagation of sea breeze front: near the coast, wind speed, and radiation peaks are close and consequently a single daily evaporation peak appears in the afternoon; at the Dead Sea, about a 100 km inland, the sea breeze front arrives at sunset, resulting in a diurnal evaporation cycle characterized by a distinct double peak.

Water is in high demand for farmers regardless of where you go. Unfortunately, farmers in southern Florida have fewer options for water supplies than public users and are often limited to using available supplies from surface and ground water sources which depend in part upon variable weather patterns. There is an interest by the agricultural community about the effect weather has on usable surface water, however, research into viable weather patterns during La Nina and El Nino has yet to be researched. Using rainfall accumulation data from NASA Tropical Rainfall Measurement Mission (TRMM) satellite, this project s purpose was to assess the influence of El Nino and La Nina Oscillations on sea breeze thunderstorm patterns, as well as general rainfall patterns during the summer season in South Florida. Through this research we were able to illustrate the spatial and temporal variations in rainfall accumulation for each oscillation in relation to major agricultural areas. The study period for this project is from 1998, when TRMM was first launched, to 2009. Since sea breezes in Florida typically occur in the months of May through October, these months were chosen to be the months of the study. During this time, there were five periods of El Nino and two periods of La Nina, with a neutral period separating each oscillation. In order to eliminate rainfall from systems other than sea breeze thunderstorms, only days that were conducive to the development of a sea breeze front were selected.

To test a methodology for assessing the effects of electronic mobility aid devices (EMAD) on the mobility of persons who are deaf-blind in real-life situations. A single-subject desing was done with four users followed in a program for persons who are deaf-blind. Participants were trained to use two commercial EMADs: the Miniguide and the Breeze. The Canadian Measure of Occupational Performance (CMOP) was administered before training (T1), after training (T2) and three months later (T3). The Quebec User Evaluation of Satisfaction with assistive Technology (QUEST) was administered at T2 and T3. A follow-up interview was conducted with the participants and clinicians at T3 to evaluate the benefits of the EMAD and any problems. CMOP suggests that both performance and satisfaction improved following the use of both EMADs in four occupations (functional mobility, active leisure, community life and socialization). QUEST indicates high satisfaction with eight items except for one participant. Follow-up interviews revealed a wide variety of perceptions regarding EMAD use and seven problems although CMOP and QUEST indicated good satisfaction. A high satisfaction score on QUEST does not necessarily imply that an assistive device is efficient in all circumstances; follow-up interviews provided important complementary information. For people who are deaf-blind The Miniguide is reliable for detecting obstacles (vibrations are sent as a warning when approaching an obstacle). It is often used to know if taking the right route. It identifies entrances or openings (indicated by the vibrations stopping when pointing at a wall), which can replace the echo-location for blind persons with hearing impairments. The Miniguide helped to locate overhanging objects which are not detectable with a long cane. The Breeze can record landmarks for orientation and it possible to use those landmarks to go back alone later after taking a certain route for the first time with someone else. It helps to familiarize the person with new places. It can tell you where you are at any time. It helps with orientation and the participant also liked this feature because it helped with learning street names. The Miniguide and the Breeze were not efficient in all circumstances; there were some problems with the ergonomic (both), detecting snow banks (Miniguide), sensitiveness to the surroundings in crowded places (Miniguide) and exactitude for geo-localization (Breeze).

The introduction into a mesoscale model of random (in space) variations in roughness length, or random (in space and time) surface perturbations of temperature and friction velocity, produces a measurable, but barely significant, response in the simulated flow dynamics of the lower atmosphere. The perturbations are an attempt to include the effects of sub-grid variability into the ensemble-mean parameterization schemes used in many numerical models. Their magnitude is set in our experiments by appeal to real-world observations of the spatial variations in roughness length and daytime surface temperature over the land on horizontal scales of one to several tens of kilometers. With sea-breeze simulations, comparisons of a number of realizations forced by roughness-length and surface-temperature perturbations with the standard simulation reveal no significant change in ensemble mean statistics, and only small changes in the sea-breeze vertical velocity. Changes in the updraft velocity for individual runs, of up to several cms-1 (compared to a mean of 14 cms-1), are directly the result of prefrontal temperature changes of 0.1 to 0.2K, produced by the random surface forcing. The correlation and magnitude of the changes are entirely consistent with a gravity-current interpretation of the sea breeze.

The highest observed surface ozone concentrations in the Houston metropolitan area in 2013 occurred on September 25, which coincided with the Texas DISCOVER-AQ (Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality) field campaign. Surface ozone was elevated throughout the Houston metropolitan area with maximum 8-hour average ozone peaking along the western shore of Galveston Bay, reaching 124 ppbv, almost 50 ppbv above the current EPA standard of 75 ppbv. The NASA P-3B aircraft observed plumes from refinery flares west and northwest of Galveston Bay that were transported over the water. Continental air pollution from the north was transported into the Houston metropolitan area where it mixed with locally generated emissions. A bay breeze circulation formed causing pollutants that were transported out over the water in the morning to recirculate back inland where they mixed with freshly emitted pollution near the bay breeze convergence zone. The highest surface ozone concentrations were reported near the bay breeze front. This ozone episode will be presented using measurements made during the DISCOVER-AQ field campaign and a CMAQ model simulation with integrated source apportionment, which tracks the contribution of emissions source groups and regions on ozone concentrations.

In this paper we examine the variations of the boreal summer season sea breeze circulation along the Florida panhandle coast from relatively high resolution (10 km) regional climate model integrations. The 23 year climatology (1979–2001) of the multidecadal dynamically downscaled simulations forced by the National Centers for Environmental Prediction–Department of Energy (NCEP-DOE) Reanalysis II at the lateral boundaries verify quite well with the observed climatology. The variations at diurnal and interannual time scales are also well simulated with respect to the observations. We show from composite analyses made from these downscaled simulations that sea breezes in northwestern Florida are associated with changes in the size of the Atlantic Warm Pool (AWP) on interannual time scales. In large AWP years when the North Atlantic Subtropical High becomes weaker and moves further eastward relative to the small AWP years, a large part of the southeast U.S. including Florida comes under the influence of relatively strong anomalous low-level northerly flow and large-scale subsidence consistent with the theory of the Sverdrup balance. This tends to suppress the diurnal convection over the Florida panhandle coast in large AWP years. This study is also an illustration of the benefit of dynamic downscaling in understanding the low-frequency variations of the sea breeze.

Tohidi, A.; Jamali, M.

2017-12-01

Various natural phenomena, e. g. uniform/non-uniform solar radiation and diurnal cycles, affect water circulation patterns through aquatic canopies, that is (usually shallow) shorelines of the rivers, lakes, and lagoons. Amongst these factors is vegetation that, plays a crucial role in conserving and dispersing the nutrients, oxygen, temperature, and generally regulating the life and interactions of organisms with each other (ecology) in aquatic canopies. So far, however, very little attention has been paid to the effects of very low, breeze-like, winds over the water surface in these vegetated regions. In this exploratory study, the evolution of a breeze-driven gravity current traveling up the slope towards the shorelines is shown, experimentally. The flow is characterized using Particle Image Velocimetry (PIV) technique. In addition, a detailed dimensional analysis of the parameter space of the phenomenon is conducted. The results strongly corroborate the experimental observations.

A field experiment was held in the northwestern Taiwan as a part of a long-term research program for studying Taiwan`s local circulation. The program has been named as Taiwan Regional-circulation Experiment (TREX). The particular goal of this research is to investigate characteristics of boundary layer and local Circulation and their impact on the distribution and Variation of pollutants in the northwestern Taiwan during Mei-Yu season. It has been known for quite sometime that land-sea breeze is very pronounced under hot and humid conditions. Extensive network includes 11 pilot ballon stations, 3 acoustic sounding sites, and 14 surface stations in aboutmore » 20 km by 20 km area centered at National Central University, Chung-Li. In addition, there are ground temperature measurements at 3 sites, Integrated Sounding System (ISS) at NCU, air plane observation, tracer experiment with 10 collecting stations, 3 background upper-air sounding stations, 2 towers etc. NOAA and GMS satellite data, sea surface temperature radar, and precipitation data are collected. The local circulations such as land/sea breezes and mountain/valley winds, induced by thermal and topographical effects often play an important role in transporting, redistributing and transforming atmospheric pollutants. This study documents the effects of the development of local circulations and the accompanying evolution of boundary layer on the distribution and the variation of the atmospheric pollutants in the north western Taiwan during Mei-Yu season.« less

Evaluation of the atmospheric model WRF on the Qatar peninsula for a converging sea-breeze event

Qatar, a narrow peninsula covering an area of 11437 sq km, extends northwards into the Arabian Gulf for about 160km and has a maximum width of 88km. The convex shape of the coast-line and narrowness of the peninsula results in the Qatar region experiencing complex wind patterns. The geometry is favorable for formation of the land-sea breeze from both coastal sides of the peninsula. This can lead to the development of sea breeze convergence zones in the middle of the country. Although circulations arising from diurnal thermal contrast of land and water are amongst most intensively studied meteorological phenomena, there is no reported study for the Qatar peninsula and very few studies are reported for the Arabian Gulf region as whole. It is necessary to characterize the wind field for applications such as assessing air pollution, renewable energy etc. A non-hydrostatic mesoscale model, Weather Research and Forecast (WRF) with a nested high resolution grid permits the investigation of such fine scale phenomena. Data from eighteen land based Automated Weather Stations (AWS) and two offshore buoys deployed and maintained by the Qatar Meteorological Department were analyzed. Based on the analysis a clear case of sea breeze convergence were seen on 18 September 2015. Model simulations were used to investigate the synoptic conditions associated with the formation of this event. The season is characterized by week ambient north westerly wind over the Arabian Gulf. The WRF model performance is validated using observed in-situ data. Model simulations show that vertical extent of sea breeze cell was up to 1 km and the converging sea breeze regions were characterized with high vertical velocities. The WRF simulation also revealed that with high resolution, the model is capable of reproducing the fine scale patterns accurately. The error of predictions in the inner domain (highest resolution) are found to be relatively lower than coarse resolution domain. The maximum wind speed were of the order of 9 m/s. The period of convergence lasted approximately for about 8 hours (with maximum intensity about 2 PM local time).The model winds compared favorably for all the 18 AWS stations, with better match seen for the offshore locations.

Investigation of the Mesoscale Interaction between the Sea Breeze Circulation and the Sandhills Convection

NASA Astrophysics Data System (ADS)

Sims, Aaron P.

In the Carolinas of the United States, there are two key land-surface features over which convective precipitation often forms during the summer months. These geomorphic features are the Sandhills and coastline. Along the coastline, sea-breeze circulations regularly form and are known to initiate convection. The Sandhills is a transitional zone of sandy soil surrounded by mixture of soils that include clay and loam. It extends through the central part of the Carolinas and into Georgia and is also the origin of convective storms. The two geographical features, the coastline and the Sandhills, are in regional proximity of each other and the resultant sea-breeze front and the Sandhills convection interact during summer. During this research, the investigation of the mechanism of interaction between these two features has led to the discovery of the Sandhills front, a shallow outflow density current that develops from deep convection over the Sandhills and propagates eastward toward the coast. The convergence of the Sandhills front and the sea-breeze front initiates and enhances convection between the Sandhills and the coastline. Observations during the month of June for the period 2004 to 2015 are used to evaluate the interaction between these two phenomena. On average, these interactions occur on approximately 24% of all days in June and on 36% of all days in June when synoptic scale systems are absent. Thus, the interactions between the sea-breeze and the Sandhills circulations do contribute to the precipitation in this region. Background wind speeds and directions influence the location and the strength of convection associated with this interaction. Onshore, offshore, and southwesterly flow classifications each present different strengths and locations of the interactions. Light winds ( 3 m s-1 to 6 m s-1 ) also influence the interactions differently. Observations indicate that moderate southwesterly flow has the highest total average and total maximum precipitation amounts over the region due to the advection of warm, moist air. Light offshore flow produces the highest totals of average precipitation due to opposing background winds that helps in the development of a robust sea-breeze circulation. Onshore flow produces the least amount of precipitation. The sea breeze circulation is weak in such cases, if it exists. Vertical characteristics and the variations of different defining parameters during the interactions were evaluated using numerical simulations. To improve the representation of convection in the numerical model, modifications were made to the convective parameterization scheme and the interactions were simulated using this improved version. These modifications include the addition of subgrid scale clouds in the radiation scheme, adjustments to the convective timescale, modifications to the entrainment rates, and linking of the subcloud velocity scale to the turbulent kinetic energy from the boundary layer parameterization. Modifications improved the numerical simulations of the mesoscale convection and precipitation predictions. Numerical simulations of the wind regime classifications reveal that the strength of the interaction, intensity of convection, and the location and depth of the convection and interaction are influenced by the background winds and moisture availability. Southwesterly flow regimes have the highest levels of atmospheric instability and produce widespread regional precipitation. Light offshore winds produce the strongest interactions between the sea-breeze front and the Sandhills front. Onshore flow produces the least amount of convective precipitation. In summary, mesoscale driven interaction events occur regularly during summer months in the coastal Carolinas. The principal driving mechanisms are surface-based differential heating over the Sandhills region caused by changes in soil heat capacity and the coastal sea breeze circulation. The location and intensity of these interactions are dictated by different wind regimes that regulate the strength of the interactions and moisture availability.

Impact of Biomass Burning Aerosols on Cloud Formation in Coastal Regions

NASA Astrophysics Data System (ADS)

Nair, U. S.; Wu, Y.; Reid, J. S.

2017-12-01

In the tropics, shallow and deep convective cloud structures organize in hierarchy of spatial scales ranging from meso-gamma (2-20 km) to planetary scales (40,000km). At the lower end of the spectrum is shallow convection over the open ocean, whose upscale growth is dependent upon mesoscale convergence triggers. In this context, cloud systems associated with land breezes that propagate long distances into open ocean areas are important. We utilized numerical model simulations to examine the impact of biomass burning on such cloud systems in the maritime continent, specifically along the coastal regions of Sarawak. Numerical model simulations conducted using the Weather Research and Forecasting Chemistry (WRF-Chem) model show spatial patterns of smoke that show good agreement to satellite observations. Analysis of model simulations show that, during daytime the horizontal convective rolls (HCRs) that form over land play an important role in organizing transport of smoke in the coastal regions. Alternating patterns of low and high smoke concentrations that are well correlated to the wavelengths of HCRs are found in both the simulations and satellite observations. During night time, smoke transport is modulated by the land breeze circulation and a band of enhanced smoke concentration is found along the land breeze front. Biomass burning aerosols are ingested by the convective clouds that form along the land breeze and leads to changes in total water path, cloud structure and precipitation formation.

A technique has been developed for assimilating GOES-derived skin temperature tendencies and insolation into the surface energy budget equation of a mesoscale model so that the simulated rate of temperature change closely agrees with the satellite observations. A critical assumption of the technique is that the availability of moisture (either from the soil or vegetation) is the least known term in the model's surface energy budget. Therefore, the simulated latent heat flux, which is a function of surface moisture availability, is adjusted based upon differences between the modeled and satellite observed skin temperature tendencies. An advantage of this technique is that satellite temperature tendencies are assimilated in an energetically consistent manner that avoids energy imbalances and surface stability problems that arise from direct assimilation of surface shelter temperatures. The fact that the rate of change of the satellite skin temperature is used rather than the absolute temperature means that sensor calibration is not as critical. The sea/land breeze is a well-documented mesoscale circulation that affects many coastal areas of the world including the northern Gulf Coast of the United States. The focus of this paper is to examine how the satellite assimilation technique impacts the simulation of a sea breeze circulation observed along the Mississippi/Alabama coast in the spring of 2001. The technique is implemented within the PSU/NCAR MM5 V3-4 and applied on a 4-km domain for this particular application. It is recognized that a 4-km grid spacing is too coarse to explicitly resolve the detailed, mesoscale structure of sea breezes. Nevertheless, the model can forecast certain characteristics of the observed sea breeze including a thermally direct circulation that results from differential low-level heating across the land-sea interface. Our intent is to determine the sensitivity of the circulation to the differential land surface forcing produced via the assimilation of GOES skin temperature tendencies. Results will be quantified through statistical verification techniques.

A field experiment was conducted on the northern Yucatan coast from April 1 to April 12, 2014 to investigate the role of intense wind events on coastal circulation from the inner shelf to the swash zone. The study area is characterized by a micro-tidal environment, low-energy wave conditions, and a wide and shallow continental shelf. Furthermore, easterly trade winds, local breezes, and synoptic-scale events, associated with the passage of cold-fronts known as Nortes, are ubiquitous in this region. Currents were measured concurrently at different cross-shore locations during both local and synoptic-scale intense wind events to investigate the influence of different forcing mechanisms (i.e., large-scale currents, winds, tides, and waves) on the nearshore circulation. Field observations revealed that nearshore circulation across the shelf is predominantly alongshore-directed (westward) during intense winds. However, the mechanisms responsible for driving instantaneous spatial and temporal current variability depend on the weather conditions and the across-shelf location. During local strong sea breeze events (W > 10 m s-1 from the NE) occurring during spring tide, westward circulation is controlled by the tides, wind, and waves at the inner-shelf, shallow waters, and inside the surf/swash zone, respectively. The nearshore circulation is relaxed during intense land breeze events (W ≈ 9 m s-1 from the SE) associated with the low atmospheric pressure system that preceded a Norte event. During the Norte event (Wmax≈ 15 m s-1 from the NNW), westward circulation dominated outside the surf zone and was correlated to the Yucatan Current, whereas wave breaking forces eastward currents inside the surf/swash zone. The latter finding implies the existence of large alongshore velocity shear at the offshore edge of the surf zone during the Norte event, which enhances mixing between the surf zone and the inner shelf. These findings suggest that both sea breezes and Nortes play an important role in sediment and pollutant transport along/across the nearshore of the Yucatan shelf.

This project utilizes Tropical Rainfall Measuring Mission (TRMM) and Landsat satellite data to assess the impact of sea breeze precipitation upon areas of agricultural land use in southern Florida. Water is a critical resource to agriculture, and the availability of water for agricultural use in Florida continues to remain a key issue. Recent projections of statewide water use by 2020 estimate that 9.3 billion gallons of water per day will be demanded, and agriculture represents 47% of this demand (Bronson 2003). Farmers have fewer options for water supplies than public users and are often limited to using available supplies from surface and ground water sources which depend in part upon variable weather patterns. Sea breeze thunderstorms are responsible for much of the rainfall delivered to Florida during the wet season (May-October) and have been recognized as an important overall contributor of rainfall in southern Florida (Almeida 2003). TRMM satellite data was used to analyze how sea breeze-induced thunderstorms during El Nino and La Nina affected interannual patterns of precipitation in southern Florida from 1998-2009. TRMM's Precipitation Radar and Microwave Imager provide data to quantify water vapor in the atmosphere, precipitation rates and intensity, and the distribution of precipitation. Rainfall accumulation data derived from TRMM and other microwave sensors were used to analyze the temporal and spatial variations of rainfall during each phase of the El Nino Southern Oscillation (ENSO). Through the use of TRMM and Landsat, slight variations were observed, but it was determined that neither sea breeze nor total rainfall patterns in South Florida were strongly affected by ENSO during the study period. However, more research is needed to characterize the influence of ENSO on summer weather patterns in South Florida. This research will provide the basis for continued observations and study with the Global Precipitation Measurement Mission.

Three atmospheric boundary layer (ABL) schemes and two land surface models that are used in the Weather Research and Forecasting (WRF) model, version 3.4.1, were evaluated with numerical simulations by using data from the north coast of France (Dunkerque). The ABL schemes YSU (Yonsei University), ACM2 (Asymmetric Convective Model version 2), and MYJ (Mellor-Yamada-Janjic) were combined with two land surface models, Noah and RUC (Rapid Update Cycle), in order to determine the performances under sea-breeze conditions. Particular attention is given in the determination of the thermal internal boundary layer (TIBL), which is very important in air pollution scenarios. The other physics parameterizations used in the model were consistent for all simulations. The predictions of the sea-breeze dynamics output from the WRF model were compared with observations taken from sonic detection and ranging, light detection and ranging systems and a meteorological surface station to verify that the model had reasonable accuracy in predicting the behavior of local circulations. The temporal comparisons of the vertical and horizontal wind speeds and wind directions predicted by the WRF model showed that all runs detected the passage of the sea-breeze front. However, except for the combination of MYJ and Noah, all runs had a time delay compared with the frontal passage measured by the instruments. The proposed study shows that the synoptic wind attenuated the intensity and penetration of the sea breeze. This provided changes in the vertical mixing in a short period of time and on soil temperature that could not be detected by the WRF model simulations with the computational grid used. Additionally, among the tested schemes, the combination of the localclosure MYJ scheme with the land surface Noah scheme was able to produce the most accurate ABL height compared with observations, and it was also able to capture the TIBL.

Strong vertical gradients at the top of the atmospheric boundary layer affect the propagation of electromagnetic waves and can produce radar ducts. A three-dimensional, time-dependent, nonhydrostatic numerical model was used to simulate the propagation environment in the atmosphere over the Persian Gulf when aircraft observations of ducting had been made. A division of the observations into high- and low-wind cases was used as a framework for the simulations. Three sets of simulations were conducted with initial conditions of varying degrees of idealization and were compared with the observations taken in the Ship Antisubmarine Warfare Readiness/Effectiveness Measuring (SHAREM-115) program. The best results occurred with the initialization based on a sounding taken over the coast modified by the inclusion of data on low-level atmospheric conditions over the Gulf waters. The development of moist, cool, stable marine internal boundary layers (MIBL) in air flowing from land over the waters of the Gulf was simulated. The MIBLs were capped by temperature inversions and associated lapses of humidity and refractivity. The low-wind MIBL was shallower and the gradients at its top were sharper than in the high-wind case, in agreement with the observations. Because it is also forced by land-sea contrasts, a sea-breeze circulation frequently occurs in association with the MIBL. The size, location, and internal structure of the sea-breeze circulation were realistically simulated. The gradients of temperature and humidity that bound the MIBL cause perturbations in the refractivity distribution that, in turn, lead to trapping layers and ducts. The existence, location, and surface character of the ducts were well captured. Horizontal variations in duct characteristics due to the sea-breeze circulation were also evident. The simulations successfully distinguished between high- and low-wind occasions, a notable feature of the SHAREM-115 observations. The modeled magnitudes of duct depth and strength, although leaving scope for improvement, were most encouraging.

The atmospheric boundary layer (ABL) over a given coastal station is influenced by the presence of mesoscale sea breeze circulation, together with the local and synoptic weather, which directly or indirectly modulate the vertical thickness of ABL ( z ABL). Despite its importance in the characterization of lower tropospheric processes and atmospheric modeling studies, a reliable climatology on the temporal evolution of z ABL is not available over the tropics. Here, we investigate the challenges involved in determination of the ABL heights, and discuss an objective method to define the vertical structure of coastal ABL. The study presents a two year morphology on the diurnal evolution of the vertical thickness of sea breeze flow ( z SBF) and z ABL in association with the altitudes of lifting condensation level ( z LCL) over Thiruvananthapuram (8.5∘ N, 76.9∘ E), a representative coastal station on the western coastline of the Indian sub-continent. We make use of about 516 balloon-borne GPS sonde measurements in the present study, which were carried out as part of the tropical tropopause dynamics field experiment under the climate and weather of the sun-earth system (CAWSES)-India program. Results obtained from the present study reveal major differences in the temporal evolution of the ABL features in relation to the strength of sea breeze circulation and monsoonal wind flow during the winter and summer monsoon respectively. The diurnal evolution in z ABL is very prominent in the winter monsoon as against the summer monsoon, which is attributed to the impact of large-scale monsoonal flow over the surface layer meteorology. For a majority of the database, the z LCL altitudes are found to be higher than that of the z ABL, indicating a possible decoupling of the ABL with the low-level clouds.

The Mesoscale Atmospheric Processes Research Program is a program of integrated studies which are to achieve an improved understanding of the basic behavior of the atmosphere through the use of remotely sensed data and space technology. The program consist of four elements: (1) special observations and analysis of mesoscale systems; (20 the development of quanitative algorithms to use remotely sensed observations; (3) the development of new observing systems; and (4) numerical modeling. The Severe Storms Branch objectives are the improvement of the understanding, diagnosis, and prediction of a wide range of atmospheric storms, which includes severe thunderstorms, tornadoes, flash floods, tropical cyclones, and winter snowstorms. The research often shed light upon various aspects of local weather, such as fog, sea breezes, air pollution, showers, and other products of nonsevere cumulus cloud clusters. The part of the program devoted to boundary layer processes, gust front interactions, and soil moisture detection from satellites gives insights into storm growth and behavior.

Investigation of mesoscale precipitation processes in the Carolinas using a radar-based climatology

NASA Astrophysics Data System (ADS)

Boyles, Ryan Patrick

The complex topography, shoreline, soils, and land use patterns makes the Carolinas a unique location to study mesoscale processes. Using gage-calibrated radar estimates and a series of numerical model simulations, warm season mesoscale precipitation patterns are analyzed over the Carolinas. Gage-calibrated radar precipitation estimates are compared with surface gage observations. Stage IV estimates generally compared better than Stage II estimates, but some Stage II and Stage IV estimates have gross errors during autumn, winter, and spring seasons. Analysis of days when sea breeze is observed suggests that sea breeze induced precipitation occurs on nearly 40% of days in June, July, and August, but only 18% in May and 6% of days in April. Precipitation on days with sea breeze convection can contribute to over 50% of seasonal precipitation. Rainfall associated with sea breeze is generally maximized along east-facing shores 10-20 km inland, and minimized along south-facing shores in North Carolina. The shape of the shoreline along Cape Fear is associated with a local precipitation maximum that may be caused by the convergence of two sea breeze fronts from the south and east shores. Differential heating associated with contrasting soils along the Carolina Sandhills is suggested as a mechanism for enhancement in local precipitation. A high-resolution summer precipitation climatology suggests that precipitation is enhanced along the Sandhills region in both wet and dry years. Analysis of four numerical simulations suggests that contrasts in soils over the Carolinas Sandhills dominates over vegetation contrasts to produce heat flux gradients and a convergence zone along the sand-to-clay transition. Orographically induced precipitation is consistently observed in the summer, and appears to be isolated along windward slopes at 20km--40km from the ridge line. Amounts over external ridges are generally 50-100% higher than amounts observed over the foothills. Precipitation amounts over interior ridges and valleys are lower than observed on exterior ridges and are similar to values observed over the foothills. When compared with Stage IV estimates, the PRISM (Precipitation-elevation Regressions on Independent Slopes Model) method for estimating precipitation in complex terrain appears to largely over-estimate precipitation amounts over the interior ridges.

A study of atmospheric dispersion of radionuclides at a coastal site using a modified Gaussian model and a mesoscale sea breeze model

NASA Astrophysics Data System (ADS)

Venkatesan, R.; Mathiyarasu, R.; Somayaji, K. M.

Ground level concentration and sky-shine dose due to radioactive emissions from a nuclear power plant at a coastal site have been estimated using the standard Gaussian Plume Model (GPM) and the modified GPM suggested by Misra (Atmospheric Environment 14 (1980) 397), which incorporates fumigation effect under sea breeze condition. The difference in results between these two models is analysed in order to understand their significance and errors that would occur if proper choice were not made. Radioactive sky-shine dose from 41Ar, emitted from a 100 m stack of the nuclear plant is continuously recorded by environmental gamma dose monitors and the data is used to validate the modified GPM. It is observed that the dose values increase by a factor of about 2 times than those of the standard GPM estimates, up to a downwind distance of 6 km during sea breeze hours. In order to examine the dispersion of radioactive effluents in the mesoscale range, a sea breeze model coupled with a particle dispersion model is used. The deposited activity, thyroid dose and sky-shine radioactive dose are simulated for a range of 30 km. In this range, the plume is found to deviate from its straight-line trajectory, as otherwise assumed in GPM. A secondary maximum in the concentration and the sky-shine dose is also observed in the model results. These results are quite significant in realistically estimating the area affected under any unlikely event of an accidental release of radioactivity.

The combined analysis of (222)Rn activity concentrations and mesoscale meteorological conditions at Huelva city (Spain) was addressed in this study to understand the potential impact of phosphogypsum piles on the (222)Rn activity concentrations registered at this area. Hourly mean data from April 2012 to February 2013 registered at two sampling sites (Huelva city and in the background station of El Arenosillo, located 27 km to the south-east) have been used in the study. The results of the present study showed a large difference in mean radon concentrations between the two stations during the sampling period, 6.3 ± 0.4 Bq m(-3) at Huelva and 3.0 ± 0.2 Bq m(-3) at El Arenosillo. The analysis has demonstrated that hourly (222)Rn concentrations at Huelva city above 22 Bq m(-3), with nocturnal peaks up to 50 Bq/m(3), mainly coincided with the occurrence of a pure sea-land breeze cycle. Mesoscale circulations in this region are mainly characterized by two patterns of sea-land breeze, pure and non-pure, with the phosphosypsum piles directly upstream (south) of the city during the afternoon on pure sea-breeze days. The difference between mean (222)Rn activity concentrations at Huelva city were 9.9 ± 1.5 Bq m(-3) for the pure pattern and 3.3 ± 0.5 Bq m(-3) for the non-pure pattern, while in the background station concentrations were 3.9 ± 0.4 Bq m(-3) and 2.8 ± 0.4 Bq m(-3) respectively. Considering these large differences, a detailed analysis of composites and case studies of representative sea-land breeze cycles of both types and their impact on (222)Rn activity concentration was performed. The results suggested that the presence of the phosphogypsum piles was necessary in order to justify the high (222)Rn activity concentrations observed at Huelva compared with the background station in the afternoons on pure sea breeze days (1.5-2.0 Bq m(-3)). On the other hand, large night time differences between the two sites on these days were likely to be associated with a combination of shallow density currents travelling down the Guadalquivir valley and, again, the presence of phosphogypsum piles. The results have demonstrated a significant impact of the phosphogypsum piles on (222)Rn activity concentrations in Huelva city during the occurrence of pure sea breeze days.

PM(2.5) and VOCs (benzene, toluene, m-p-o-xylenes) concentrations were measured in an urban and a suburban site in Athens, Greece, during the period between April and November 2004. This period, which is considered to be the warmer period in Greece, is characterized by the development of sea-breeze over the Attica Basin. Additionally strong Northern, North-eastern winds called "The Etesians", predominate during the summer months (July-August), acting positively to the dispersion of pollutants. In this campaign, 24 days with sea-breeze development were observed, 15 days with northern winds, 6 days with southern winds while the rest of the days presented no specific wind profile. Maximum concentrations of PM(2.5), VOCs and nitrogen oxides, were detected during the days with sea-breeze, while minimum concentrations during the days with northern winds. Ozone was the only pollutant that appeared to have higher concentrations in the background site and not in the city centre, where benzene presented strong negative correlation with ozone, indicating the photochemical reaction of hydrocarbons that lead to the ozone formation. The BTX ratios were similar for both sites and wind profiles, indicating common sources for those pollutants. T/B ratio ranged in low levels, between 3-5 for site A and 2-5 for site B, suggesting vehicles emissions as the main sources of volatile compounds. Finally, the strong correlations of PM(2.5) and benzene concentrations, between the two sampling sites, indicate that both the city centre and the background site, are affected by the same sources, under common meteorological conditions (sea-breeze, northern winds).

A sophisticated land-surface model, PLACE, the Parameterization for Land Atmospheric Convective Exchange, has been coupled to a 1.5-order turbulent kinetic energy (TKE) turbulence sub-model. Both have been incorporated into the Penn State/National Center for Atmospheric Research (PSU/NCAR) mesoscale model MM5. Such model improvements should have their greatest effect in conditions where surface contrasts dominate over dynamic processes, such as the simulation of warm-season, convective events. A validation study used the newly coupled model, MM5 TKE-PLACE, to simulate the evolution of Florida sea-breeze moist convection during the Convection and Precipitation Electrification Experiment (CaPE). Overall, eight simulations tested the sensitivity of the MM5 model to combinations of the new and default model physics, and initialization of soil moisture and temperature. The TKE-PLACE model produced more realistic surface sensible heat flux, lower biases for surface variables, more realistic rainfall, and cloud cover than the default model. Of the 8 simulations with different factors (i.e., model physics or initialization), TKE-PLACE compared very well when each simulation was ranked in terms of biases of the surface variables and rainfall, and percent and root mean square of cloud cover. A factor separation analysis showed that a successful simulation required the inclusion of a multi-layered, land surface soil vegetation model, realistic initial soil moisture, and higher order closure of the planetary boundary layer (PBL). These were needed to realistically model the effect of individual, joint, and synergistic contributions from the land surface and PBL on the CAPE sea-breeze, Lake Okeechobee lake breeze, and moist convection.

Sea breeze occurs at coastal regions around the world, with great impacts on the weather and air quality. Observations and forecasts of the fine-scale structures and local impacts of sea-breeze front (SBF) are a challenge. Three-dimensional structures of a quasi-stationary SBF were observed by dual-Doppler lidar over Sendai Airport in June 2007. Using a state-of-the-art local prediction system in which a computational fluid dynamics model is nested to a mesoscale model with data assimilation, we perform a realistic simulation of the observed SBF structures at 10-m resolution. Numerical simulations reproduce the detailed features of the SBF, such as frontal lobes/clefts, intense updrafts, rear downdrafts, and Kelvin-Helmholtz billows, consistent with lidar observations. Several localized maxima of updrafts occur at the active SBF lobes with ascending marine air mass and adjacent windward sides, where the ambient warm flows encounter a steep front face and penetrate SBF aloft. Strong downdrafts of marine cool air dominate at the SBF rear where they trap a high concentration of air pollutants. These features are regularly activated by the arc-shaped gravity currents at a horizontal scale of several kilometers and a period of 30 minutes. They are also influenced by the coastal buildings and strongly regulate the spatio-temporal variations of local winds near surface. The findings suggest that a novel full-scale nested prediction system has potential for forecasting coastal weather and environment at high precision, which are valuable for aviation safety, marine activities, and air quality monitoring.

Booster sessions as a means of maintaining the benefits of psycho-educational programs have received little attention in caregiving research. Caregivers were offered a booster session following participation in a program entitled Learning to Become a Family Caregiver (LBFC) intended to facilitate transition to the caregiver role after diagnostic disclosure of dementia in a relative. The 90-minute booster session served to review program content and afforded the opportunity to discuss and practice learned skills. This study sought to test the efficacy of the booster session in maintaining or recovering program effects at six months post-program. Participants in the program were randomly assigned to a group that received the booster session (n = 31) or a group that did not (n = 29). A third control group was also formed, which continued to receive only the usual care provided in memory clinics. Eligible participants - French-speaking primary caregivers of a relative diagnosed with Alzheimer's in the past nine months - were recruited in memory clinics in Quebec (Canada). Participants were blindly assessed before randomization and six months after the booster session on outcomes associated with a healthy role transition. Prediction analyses revealed one significant positive effect of the booster session: emergence of preparedness to provide care. Moreover, with or without the booster session, the program continued to have a positive effect on psychological distress and contributed to the emergence of self-efficacy in dealing with caregiving situations. The booster session had no significant effect on knowledge of services, planning for future care needs, use of reframing as a coping strategy, perceived informal support, and family conflicts. The limited effect observed is discussed in terms of the booster session's content and intensity. Recommendations are made for designing future research on the effect of booster sessions, including the importance of including a placebo booster group.

Remote programming is safe and is well received by health-care professionals and cochlear implant (CI) users. It can be adopted into clinic routine as an alternative to face-to-face programming. Telemedicine allows a patient to be treated anywhere in the world. Although it is a growing field, little research has been published on its application to CI programming. We examined hearing professionals' and CI users' subjective reactions to the remote programming experience, including the quality of the programming and the use of the relevant technology. Remote CI programming was performed in Italy, Sweden, and Russia. Programming sessions had three participants: a CI user, a local host, and a remote expert. After the session, each CI user, local host, and remote expert each completed a questionnaire on their experience. In all, 33 remote programming sessions were carried out, resulting in 99 completed questionnaires. The overwhelming majority of study participants responded positively to all aspects of remote programming. CI users were satisfied with the results in 96.9% of the programming sessions; 100% of participants would use remote programming again. Although technical problems were encountered, they did not cause the sessions to be considerably longer than face-to-face sessions.

Scaling and Numerical Model Evaluation of Snow-Cover Effects on the Generation and Modification of Daytime Mesoscale Circulations.

Consideration of the sensible heat flux characteristics over a snow surface suggests a significant diminution in the magnitude of the flux, compared to that over a snow-free surface under the same environmental conditions. Consequently, the existence of snow-covered mesoscale areas adjacent to snow-free areas produces horizontal thermal gradients in the lower atmosphere during the daytime, possibly resulting in a `snow breeze.' In addition, suppression of the daytime thermally induced upslope flow over snow-covered slopes is likely to occur. The present paper provides scaling and modeling evaluations of these situations, with quantification of the generated and modified circulations. These evaluations suggest that under ideal situations involved with uniform snow cover over large areas, particularly in late winter and early spring, a noticeable `snow breeze' is likely to develop. Additionally: suppression of the daytime thermally induced upslope flow is significant and may even result in a daytime drainage flow. The effects of bare ground patchiness in the snow cover on these circulations are also explored, both for flat terrain and slope-flow situations. A patchiness fraction greater than 0.5 is found to result in a noticeably reduced snow-breeze circulation, while a patchiness fraction of only 0.1 caused the simulated daytime drainage flow over slopes to he reversed.

Contour Error Map Algorithm

The contour error map (CEM) algorithm and the software that implements the algorithm are means of quantifying correlations between sets of time-varying data that are binarized and registered on spatial grids. The present version of the software is intended for use in evaluating numerical weather forecasts against observational sea-breeze data. In cases in which observational data come from off-grid stations, it is necessary to preprocess the observational data to transform them into gridded data. First, the wind direction is gridded and binarized so that D(i,j;n) is the input to CEM based on forecast data and d(i,j;n) is the input to CEM based on gridded observational data. Here, i and j are spatial indices representing 1.25-km intervals along the west-to-east and south-to-north directions, respectively; and n is a time index representing 5-minute intervals. A binary value of D or d = 0 corresponds to an offshore wind, whereas a value of D or d = 1 corresponds to an onshore wind. CEM includes two notable subalgorithms: One identifies and verifies sea-breeze boundaries; the other, which can be invoked optionally, performs an image-erosion function for the purpose of attempting to eliminate river-breeze contributions in the wind fields.

Sea-town interactions over Marseille: 3D urban boundary layer and thermodynamic fields near the surface

3D numerical simulations with the Meso-NH atmospheric model including the Town Energy Balance urban parameterization, are conducted over the south-east of France and the one million inhabitants city of Marseille in the frameworks of the ESCOMPTE-UBL program. The geographic situation of the area is relatively complex, because of the proximity of the Mediterranean Sea and the presence of numerous massifs, inducing complex meteorological flows. The present work is focused on six days of the campaign, characterized by the development of strong summer sea-breeze circulations. A complete evaluation of the model is initially realized at both regional- and city-scales, by using the large available database. The regional evaluation shows a good behavior of the model, during the six days of simulation, either for the parameters near the surface or for the vertical profiles describing the structure of the atmosphere. The urban-scale evaluation indicates that the fine structure of the horizontal fields of air temperature above the city is correctly simulated by the model. A specific attention is then pointed to the 250-m horizontal resolution outputs, focused on the Marseille area, for two days of the campaign. From the study of the vertical structure of the Urban Boundary Layer and the thermodynamic fields near the surface, one underscores the important differences due to the regional and local flows, and the complex interactions that occur between the urban effects and the effects of sea breezes.

The Advanced Regional Prediction System (ARPS) is coupled with the tropical town energy budget (tTEB) scheme to analyze the effects of the urban canopy circulation over the metropolitan area of São Paulo and its interactions with the sea breeze and mountain-valley circulation in the eastern state of São Paulo, Brazil. Two experiments are carried out for the typical sea-breeze event occurring on 22 August 2014 under weak synoptic forcing and clear-sky conditions: (a) a control run with the default semi-desert surface parametrization and; (b) a tTEB run for the urban canopy of São Paulo. A realistic land-use database over the south-eastern domain of Brazil is used in the downscaling simulation to a horizontal grid resolution of 3 km. Our results indicate that ARPS effectively simulates features of the nighttime and early morning land-breeze circulation, which is affected by the surrounding hills and the nocturnal heat island of São Paulo. By early afternoon, the south-eastern sea-breeze circulation moves inland perpendicular to the upslope of the Serra do Mar scarp, which generates a line of moisture convergence and updrafts further inland. Later, the convergence line reaches São Paulo and interacts with the circulation arising from the urban heat island (UHI), which increases the moisture convergence and strength of updrafts. The surface energy balance indicates that the UHI is caused by large sensible heat storage within the urban canopy during the day, which is later released in the afternoon and at night. The simulations are verified with available radiosonde and surface weather station data, land-surface-temperature estimates from the moderate resolution imaging spectroradiometer, as well as the National Center for Atmospheric Research reanalysis databases. The three-dimensional geometry of the urban canyons within the tTEB scheme consistently improves the thermodynamically-induced circulation over São Paulo.

Coastal atmospheric conditions widely vary from those over inland due to the land-sea interface, temperature contrast and the consequent development of local circulations. In this study a field meteorological experiment was conducted to measure vertical structure of boundary layer during the period 25–29 June, 2007 at three locations Seabee base, Harrison and Wiggins sites in the Mississippi coast. A GPS Sonde along with slow ascent helium balloon and automated weather stations equipped with slow and fast response sensors were used in the experiment. GPS sonde were launched at three specific times (0700 LT, 1300 LT and 1800 LT) during the experiment days. The observations indicate shallow boundary layer near the coast which gradually develops inland. The weather research and forecasting (WRF) meso-scale atmospheric model and a Lagrangian particle dispersion model (HYSPLIT) are used to simulate the lower atmospheric flow and dispersion in a range of 100 km from the coast for 28–30 June, 2007. The simulated meteorological parameters were compared with the experimental observations. The meso-scale model results show significant temporal and spatial variations in the meteorological fields as a result of development of sea breeze flow, its coupling with the large scale flow field and the ensuing alteration in the mixing depth across the coast. Simulated ground-level concentrations of SO2 from four elevated point sources located along the coast indicate diurnal variation and impact of the local sea-land breeze on the direction of the plume. Model concentration levels were highest during the stable morning condition and during the sea-breeze time in the afternoon. The highest concentrations were found up to 40 km inland during sea breeze time. The study illustrates the application of field meteorological observations for the validation of WRF which is coupled to HYSPLIT for dispersion assessment in the coastal region. PMID:19151446

Here, we review liquid hydrogen (LH 2) as a maritime vessel fuel, from descriptions of its fundamental properties to its practical application and safety aspects, in the context of the San Francisco Bay Renewable Energy Electric Vessel with Zero Emissions (SF-BREEZE) high-speed fuel-cell ferry. Since marine regulations have been formulated to cover liquid natural gas (LNG) as a primary propulsion fuel, we frame our examination of LH 2 as a comparison to LNG, for both maritime use in general, and the SF-BREEZE in particular. Due to weaker attractions between molecules, LH 2 is colder than LNG, and evaporates more easily.more » We describe the consequences of these physical differences for the size and duration of spills of the two cryogenic fuels. The classical flammability ranges are reviewed, with a focus on how fuel buoyancy modifies these combustion limits. We examine the conditions for direct fuel explosion (detonation) and contrast them with initiation of normal (laminar) combustion. Direct fuel detonation is not a credible accident scenario for the SF-BREEZE. For both fuels, we review experiments and theory elucidating the deflagration to detonation transition (DDT). LH 2 fires have a shorter duration than energy-equivalent LNG fires, and produce significantly less thermal radiation. The thermal (infrared) radiation from hydrogen fires is also strongly absorbed by humidity in the air. Hydrogen permeability is not a leak issue for practical hydrogen plumbing. We describe the chemistry of hydrogen and methane at iron surfaces, clarifying their impact on steel-based hydrogen storage and transport materials. These physical, chemical and combustion properties are pulled together in a comparison of how a LH 2 or LNG pool fire on the Top Deck of the SF-BREEZE might influence the structural integrity of the aluminum deck. Neither pool fire scenario leads to net heating of the aluminum decking. Overall, LH 2 and LNG are very similar in their physical and combustion properties, thereby posing similar safety risks. For ships utilizing LH 2 or LNG, precautions are needed to avoid fuel leaks, minimize ignition sources, minimize confined spaces, provide ample ventilation for required confined spaces, and to monitor the enclosed spaces to ensure any fuel accumulation is detected far below the fuel/air mix threshold for any type of combustion.« less

Since marine regulations have been formulated to cover liquid natural gas (LNG) as a primary propulsion fuel, we frame our examination of LH 2 as a comparison to LNG, for both maritime use in general, and the SF-BREEZE in particular. Due to weaker attractions between molecules, LH 2 is colder than LNG, and evaporates more easily.more » We describe the consequences of these physical differences for the size and duration of spills of the two cryogenic fuels. The classical flammability ranges are reviewed, with a focus on how fuel buoyancy modifies these combustion limits. We examine the conditions for direct fuel explosion (detonation) and contrast them with initiation of normal (laminar) combustion. Direct fuel detonation is not a credible accident scenario for the SF-BREEZE. For both fuels, we review experiments and theory elucidating the deflagration to detonation transition (DDT). LH 2 fires have a shorter duration than energy-equivalent LNG fires, and produce significantly less thermal radiation. The thermal (infrared) radiation from hydrogen fires is also strongly absorbed by humidity in the air. Hydrogen permeability is not a leak issue for practical hydrogen plumbing. We describe the chemistry of hydrogen and methane at iron surfaces, clarifying their impact on steel-based hydrogen storage and transport materials. These physical, chemical and combustion properties are pulled together in a comparison of how a LH 2 or LNG pool fire on the Top Deck of the SF-BREEZE might influence the structural integrity of the aluminum deck. Neither pool fire scenario leads to net heating of the aluminum decking. Overall, LH 2 and LNG are very similar in their physical and combustion properties, thereby posing similar safety risks. For ships utilizing LH 2 or LNG, precautions are needed to avoid fuel leaks, minimize ignition sources, minimize confined spaces, provide ample ventilation for required confined spaces, and to monitor the enclosed spaces to ensure any fuel accumulation is detected far below the fuel/air mix threshold for any type of combustion.« less

The purpose of the first scientific working group meeting was fourfold: (1) to identify flight test options for engineering verification of the MSFC Doppler Lidar; (2) to identify flight test options for gathering data for scientific/technology applications; (3) to identify additional support equipment needed on the CV 990 aircraft for the flight tests; and (4) to identify postflight data processing and data sets requirements. The working group identified approximately ten flight options for gathering data on atmospheric dynamics processes, including turbulence, valley breezes, and thunderstorm cloud anvil and cold air outflow dynamics. These test options will be used as a basis for planning the fiscal year 1981 tests of the Doppler Lidar system.

A scale model wind tunnel study of dispersion in the Cleveland area. Laboratory simulation of lake breeze effects on diffusion from ground level emissions

NASA Technical Reports Server (NTRS)

Hoydysh, W. G.

1974-01-01

A wind tunnel simulation of the diffusion patterns in a sea breeze was attempted. The results indicate that the low level onshore flow was well simulated for neutral, stable, unstable, and elevated inversion conditions. Velocity, turbulence, shear stress, and temperature data were taken, and the spread of emissions from ground level sources was investigated. Comparison is made with theoretical predictions by E. Inoue and with the open, homogeneous plane field results of Pasquill. Agreement with the predictions by Inoue is good, and the comparison with Pasquill's results shows that the wind tunnel flows are shifted two categories towards more stable. The discrepancy may be explained as a matter of averaging time.

The emergency response dose assessment system (ERDAS) is a protype software and hardware system configured to produce routine mesoscale meteorological forecasts and enhanced dispersion estimates on an operational basis for the Kennedy Space Center (KSC)/Cape Canaveral Air Station (CCAS) region. ERDAS provides emergency response guidance to operations at KSC/CCAS in the case of an accidental hazardous material release or an aborted vehicle launch. This report describes the evaluation of ERDAS including: evaluation of sea breeze predictions, comparison of launch plume location and concentration predictions, case study of a toxic release, evaluation of model sensitivity to varying input parameters, evaluation of the user interface, assessment of ERDA's operational capabilities, and a comparison of ERDAS models to the ocean breeze dry gultch diffusion model.

The effect of water temperature and synoptic winds on the development of surface flows over narrow, elongated water bodies

Simulations of the thermally induced breeze involved with a relatively narrow, elongated water body is presented in conjunction with evaluations of sensible heat fluxes in a stable marine atmospheric surface layer. The effect of the water surface temperature and of the large-scale synoptic winds on the development of surface flows over the water is examined. As implied by the sensible heat flux patterns, the simulation results reveal the following trends: (1) when the synoptic flow is absent or light, the induced surface breeze is not affected noticeably by a reduction of the water surface temperature; and (2) for stronger synoptic flow, the resultant surface flow may be significantly affected by the water surface temperature.

The mesoscale numerical model of the University of Virginia (UVMM), has been applied to the greater Chesapeake Bay area in order to provide a detailed description of the air pollution meteorology during a typical summer day. This model provides state of the art simulations for land-sea thermally induced circulations. The model-predicted results agree favorably with available observed data. The effects of synoptic flow and sea breeze coupling on air pollution meteorological characteristics in this region, are demonstrated by a spatial and temporal presentation of various model predicted fields. A transport analysis based on predicted wind velocities indicated possible recirculation of pollutants back onto the Atlantic coast due to the sea breeze circulation.

The purpose of this study was to evaluate the effects of a sex education program, which was based on the Health Belief Model, on knowledge related to sexually transmitted diseases and sexual autonomy among university students. A non-equivalent control group, pretest-posttest design was used. The four session program was delivered to 18 students during 4 weeks; the control group consisted of 23 students. The theme of the first session was "sex, gender, and sexuality: all our concern", "dangerous sex" for the second session, "safe sex" for the third session, and "right sex for you and me" for the fourth session. At follow-up, the knowledge related to sexually transmitted diseases and sexual autonomy were significantly greater in the intervention group than in the control group. A sex education program with several sessions within the theoretical frame of HBM was effective to improve knowledge related to sexually transmitted diseases and sexual autonomy. The results suggest the potential of a systematic sexual education program to teach healthy sex and to extend the program for other various populations.

Although several studies show symptomatic improvements in patients with personality disorders after short-term inpatient psychotherapy, reintegration remains difficult. In this study the effectiveness of a specifically designed reintegration training program is investigated. One hundred twenty-eight patients were randomized to either a reintegration training program aimed at improving general functioning and work resumption, or booster sessions. Outcome measures used were symptom level, work status, absence from and impediments at work. The results showed that compliance in the booster session group was significantly better than in the reintegration training program. The percentage of persons with a paid job increased during the booster sessions from 64 to 87%, but not during the reintegration training (76%). There were no differences in the other outcome measures. We concluded that reintegration training was not more (cost)-effective than booster sessions. Our hypothesis is that continuity of care (same therapists and program) explains the favorable results of the booster sessions.

Parenting, Eating and Activity for Child Health (PEACH™) is a multicomponent treatment program delivered over ten group sessions to parents of overweight/obese primary school-aged children. It has been shown to be efficacious in an RCT and was recently translated to a large-scale community intervention funded by the Queensland (Australia) Government. Engagement (enrolment and attendance) was critical to achieving program outcomes and was challenging. The purpose of the present study was to examine sample characteristics and mediating factors that potentially influenced program attendance. Data collected from parents who attended at least one PEACH™ Queensland session delivered between October 2013 and October 2015 (47 programs implemented in 29 discrete sites), was used in preliminary descriptive analyses of sample characteristics and multilevel single linear regression analyses. Mediation analysis examined associations between socio-demographic and parent characteristics and attendance at group sessions and potential mediation by child and parent factors. 365/467 (78%) enrolled families (92% mothers) including 411/519 (79%) children (55% girls, mean age 9 ± 2 years) attended at least one session (mean 5.6 ± 3.2). A majority of families (69%) self-referred to the program. Program attendance was greater in: advantaged (5.9 ± 3.1 sessions) vs disadvantaged families (5.4 ± 3.4 sessions) (p < 0.05); partnered (6.1 ± 3.1 sessions) vs un-partnered parents (5.0 ± 3.1 sessions) (p < 0.01); higher educated (6.1 ± 3.0 sessions) vs lower educated parents (5.1 ± 3.3 sessions) (p = 0.02); and self-referral (6.1 ± 3.1) vs professional referral (4.7 ± 3.3) (p < 0.001). Child (age, gender, pre-program healthy eating) and parent (perceptions of child weight, self-efficacy) factors did not mediate these relationships. To promote reach and effectiveness of up-scaled programs, it is important to identify ways to engage less advantaged families who carry higher child obesity risk. Understanding differences in referral source and parent readiness for change may assist in tailoring program content. The influence of program-level factors (e.g. facilitator and setting characteristics) should be investigated as possible alternative mediators to program engagement.

Interaction between turbulent flow and sea breeze front over urban-like coast in large-eddy simulation

Turbulent flow and its interaction with a sea breeze front (SBF) over an urban-like coast with a regular block array were investigated using a building-resolving computational fluid dynamics model. It was found that during daytime with an offshore ambient flow, streaky turbulent structures tended to grow within the convective boundary layer (CBL) over a warm urban surface ahead of the SBF. The structures were organized as streamwise streaks at an interval of a few hundred meters, which initiated at the rooftop level with strong wind shear and strengthens in the CBL with moderate buoyancy. The streaks then interacted with the onshore-propagating SBF as it made landfall. The SBF, which was initially characterized as a shallow and quasi-linear feature over the sea, developed three-dimensional structures with intensified updrafts at an elevated frontal head after landfall. Frontal updrafts were locally enhanced at intersections where the streaks merged with the SBF, which greatly increased turbulent fluxes at the front. The frontal line was irregular because of merging, tilting, and transformation effects of vorticity associated with streaky structures. Inland penetration of the SBF was slowed by the frictional effect of urban-like surfaces and turbulent flow on land. The overall SBF intensity weakened after the interaction with turbulent flow. These findings aid understanding of local weather over coastal cities during typical sea breeze conditions.

To evaluate the impact of student pharmacist participation in a mock interview session on confidence level and preparation regarding residency interview skills. The study setting was a mock interview session, held in conjunction with student programming at the American College of Clinical Pharmacy (ACCP) Annual Meeting. Prior to the mock interview session, final year student pharmacists seeking residency program placement were asked to complete a pre-session survey assessing confidence level for residency interviews. Each student pharmacist participated in up to three mock interviews. A post-session survey evaluating confidence level was then administered to consenting participants. Following the American Society for Health-System Pharmacists (ASHP) Pharmacy Resident Matching Program (RMP), a post-match electronic survey was sent to study participants to determine their perception of the influence of the mock interview session on achieving successful interactions during residency interviews. A total of 59 student pharmacists participated in the mock interview session and completed the pre-session survey. Participants completing the post-session survey (88%, n = 52) unanimously reported an enhanced confidence in interviewing skills following the session. Thirty responders reported a program match rate of 83%. Approximately 97% (n = 29) of the respondents agreed or strongly agreed that the questions asked during the mock interview session were reflective of questions asked during residency interviews. Lessons learned from this mock interview session can be applied to PGY1 residency mock interview sessions held locally, regionally, and nationally. Students participating in the ACCP Mock Interview Session recognized the importance of the interview component in obtaining a postgraduate year 1 (PGY1) pharmacy residency.

Sessional staff is increasingly involved in teaching at universities, playing a pivotal role in bridging the gap between theory and practice for students, especially in the health professions, including pharmacy. Although sessional staff numbers have increased substantially in recent years, limited attention has been paid to the quality of teaching and learning provided by this group. This review will discuss the training and support of sessional staff, with a focus on Australian universities, including the reasons for and potential benefits of training, and structure and content of training programs. Although sessional staff views these programs as valuable, there is a lack of in-depth evaluations of the outcomes of the programs for sessional staff, students and the university. Quality assurance of such programs is only guaranteed, however, if these evaluations extend to the impact of this training and support on student learning.

Numerical simulation of local atmospheric circulations in the pre-Alpine area between Lake Garda and Verona

Laiti, L.; Serafin, S.; Zardi, D.

2010-09-01

The pre-Alpine area between Lake Garda and Verona displays a very complex and heterogeneous territory, allowing the development of several interacting systems of thermally driven local winds, the major being the lake/land breeze system on the coasts of Lake Garda and the up/down-valley wind system between the plain and the river Adige Valley. In order to investigate the local wind patterns, a series of nested numerical simulations with a horizontal resolution of 500 m were carried out using the ARPS 5.2.9 model (Xue et al. 2000, 2001), considering a fair weather day suitable for a clear development of the expected circulations (15th July 2003). The simulated wind speed and direction, pressure, temperature and water vapour mixing ratio were compared to synoptic scale meteorological charts, to vertical profiles from radiosoundings taken at the major sounding stations of the alpine region and to local scale measurements performed at the surface station of Dolcè (at the inlet of the Adige Valley). Numerical results at all scales were found to be in very good agreement with the available sets of meteorological observations. The analysis of the diurnal evolution of the 3D fields of temperature, moisture content, wind and turbulent kinetic energy allowed the identification of a very shallow and clearly defined breeze front of cold and humid air moving from off-shore towards the Lake Garda coast, from the late morning (10:00 LST) until the evening (20:00 LST). The diurnal up-valley breeze was also well reproduced: the valley atmosphere displays a thick mixed layer dominated by shallow turbulent convection between 11:00 LST and 21:00 LST. Lateral slope winds were also recognized, as they created cross-valley convective cells. While no clear evidence of a nocturnal land breeze was found in the simulations, the nocturnal down-valley wind in the Adige Valley was clearly reproduced. Finally, a scalar transport equation was added to the ARPS model in order to simulate transport and diffusion processes for a passive tracer (ideally, a non-reactive pollutant). The cold and stable lake and down-valley breeze corps were found to act like pollutant concentrators at ground level, while the diurnal up-valley wind favours an almost homogenous dispersion of the tracer through the entire Convective Boundary Layer (CBL) thickness. The upper entrainment layer is found to effectively confine the ground-emitted pollutant inside the CBL, except for some occasional plumes that are first conveyed up-slope and then to the centre of the valley above the CBL by cross-valley circulation cells.

Tai-Chi has shown benefits in physical and psychological outcomes in diverse populations. We aimed to determine the changes elicited by a Tai-Chi program (12 and 24 weeks) in acute pain (before vs. after session) in fibromyalgia patients. We also assessed the cumulative changes in pain brought about by a Tai-Chi program. Thirty-six patients (29 women) with fibromyalgia participated in a low-moderate intensity Tai-Chi program for 12 weeks (3 sessions/week). Twenty-eight patients (27 women) continued the program for an additional 12 weeks (i. e., 24 weeks). We assessed pain by means of a Visual Analogue Scale (VAS) before and after each single session (i. e., 72 sessions). We observed significant immediate changes (P-values from 0.037 to 0.0001) with an approximately 12% mean decrease of acute pain in the comparison of VAS-values before and after each session (72 sessions in total), with the exception of 4 sessions. We observed significant changes in cumulative pain pre-session (95% CI=-0.019; -0.014; P<0.001) and cumulative pain post-session (95% CI=-0.021; -0.015; P<0.001) along the 24-week intervention only. In conclusion, a low-moderate intensity Tai-Chi program for 12 weeks (3 times/week) decreased levels of acute pain in fibromyalgia patients. A longer period is necessary (e. g. 24 weeks) for observing cumulative changes in pain. © Georg Thieme Verlag KG Stuttgart · New York.

The NASA Goddard Group's Source Monitoring Database and Program

2014-12-01

Beginning in 2003, the Goddard VLBI group developed a program to purposefully monitor when sources were observed and to increase the observations of ``under-observed'' sources. The heart of the program consists of a MySQL database that keeps track of, on a session-by-session basis: the number of observations that are scheduled for a source, the number of observations that are successfully correlated, and the number of observations that are used in a session. In addition, there is a table that contains the target number of successful sessions over the last twelve months. Initially this table just contained two categories. Sources in the geodetic catalog had a target of 12 sessions/year; the remaining ICRF-1 defining sources had a target of two sessions/year. All other sources did not have a specific target. As the program evolved, different kinds of sources with different observing targets were added. During the scheduling process, the scheduler has the option of automatically selecting N sources which have not met their target. We discuss the history and present some results of this successful program.

The influence of sea-land breezes (SLBs) on the spatial distribution and temporal variation of particulate matter (PM) in the atmosphere was investigated over coastal Taiwan. PM was simultaneously sampled at inland and offshore locations during three intensive sampling periods. The intensive PM sampling protocol was continuously conducted over a 48-hr period. During this time, PM2.5 and PM(2.5-10) (PM with aerodynamic diameters < 2.5 microm and between 2.5 and 10 microm, respectively) were simultaneously measured with dichotomous samplers at four sites (two inland and two offshore sites) and PM10 (PM with aerodynamic diameters < or =10 microm) was measured with beta-ray monitors at these same 4 sites and at 10 sites of the Taiwan Air Quality Monitoring Network. PM sampling on a mobile air quality monitoring boat was further conducted along the coastline to collect offshore PM using a beta-ray monitor and a dichotomous sampler. Data obtained from the inland sites (n=12) and offshore sites (n=2) were applied to plot the PM10 concentration contour using Surfer software. This study also used a three-dimensional meteorological model (Pennsylvania State University/National Center for Atmospheric Research Meteorological Model 5) and the Comprehensive Air Quality Model with Extensions to simulate surface wind fields and spatial distribution of PM10 over the coastal region during the intensive sampling periods. Spatial distribution of PM10 concentration was further used in investigating the influence of SLBs on the transport of PM10 over the coastal region. Field measurement and model simulation results showed that PM10 was transported back and forth across the coastline. In particular, a high PM10 concentration was observed at the inland sites during the day because of sea breezes, whereas a high PM10 concentration was detected offshore at night because of land breezes. This study revealed that the accumulation of PM in the near-ocean region because of SLBs influenced the tempospatial distribution of PM10 over the coastal region.

The Potential to Promote Resilience: Piloting a Minority Stress-Informed, GSA-Based, Mental Health Promotion Program for LGBTQ Youth

This article describes the results of a pilot study to determine the feasibility and acceptability of a mental health promotion program that was developed to address minority stressors and promote coping skills among lesbian, gay, bisexual, transgender, and queer (LGBTQ) youth. It was hypothesized that the program would be feasible to implement within the context of a gay-straight alliance (GSA) and that GSA members would find the program acceptable (e.g., educational, enjoyable, helpful, and relevant). Participants included ten members of a high school GSA in the northeastern United States. The program sessions were delivered during GSA meetings. The first session emphasized the identification of minority and general stressors, which was followed by a discussion of coping strategies. The remaining sessions emphasized the development of cognitive coping, affect regulation, and problem-solving skills. After each session, participants completed a 13-item feedback form. Ten items assessed acceptability and three open-ended items allowed participants to provide constructive feedback. Although the program was feasible to implement within the GSA setting, attendance at the sessions was variable. Those who attended the sessions reported them to be enjoyable, informative, relevant to their lives, and potentially helpful for other LGBTQ students. After revising the program, future research is needed to investigate its dissemination potential and determine whether the program can disrupt the minority stress-psychiatric distress relationship.

Evaluate an educational program in the training of residents in gynecology-obstetrics (GO) with a theory session and a practical session on simulators and analyze their learning curve. Single-center prospective study, at the university hospital (CHU). Two-day sessions were leaded in April and July 2013. An evaluation on obstetric and gynecological surgery simulator was available to all residents. Theoretical knowledge principles of obstetrics were evaluated early in the session and after formal lectures was taught to them. At the end of the first session, a satisfaction questionnaire was distributed to all participants. Twenty residents agreed to participate to the training sessions. Evaluation of theoretical knowledge: at the end of the session, the residents obtained a significant improvement in their score on 20 testing knowledge. Obstetrical simulator: a statistically significant improvement in scores on assessments simulator vaginal delivery between the first and second session. Subjectively, a larger increase feeling was seen after breech delivery simulation than for the cephalic vaginal delivery. However, the confidence level of the resident after breech delivery simulation has not been improved at the end of the second session. Simulation in gynecological surgery: a trend towards improvement in the time realized on the peg-transfer between the two sessions was noted. In the virtual simulation, no statistically significant differences showed, no improvement for in salpingectomy's time. Subjectively, the residents felt an increase in the precision of their gesture. Satisfaction: All residents have tried the whole program. They considered the pursuit of these sessions on simulators was necessary and even mandatory. The approach chosen by this structured educational program allowed a progression for the residents, both objectively and subjectively. This simulation program type for the resident's training would use this tool in assessing their skills and develop learning curves. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Implementation of an "after hours" resident educational program in a general surgery residency: a paradigm for increasing formal didactic training outside of the hospital setting in the era of the 80-hour workweek.

Residency programs have been forced to curtail many educational activities to comply with duty-hour restrictions. We describe an "after hours" educational program as a forum to provide small-group education customized for each training level to compliment our formal curriculum. Sessions within each general surgery specialty were organized such that 1 session each month was open to either junior (R1 and R2) or senior (R3-R5) trainees and hosted by surgical faculty. Attendance was optional and limited to 15 residents per session with the format determined by the hosting faculty. Participants completed a postsession survey. Fourteen sessions were held during the 2008-2009 academic year. All sessions were >90% subscribed within 1 week of announcement and attendance was 88%. The average session duration was 2.6 +/- 0.4 hours. Junior resident sessions focused on preparing R1 and R2 residents to handle common consult questions; senior resident sessions were modeled as "mock oral boards." Resident and faculty responses to the postsession questionnaire were similar and favorable with respect to the educational value of this format. There is enthusiasm among faculty and trainees to provide small-group, level-specific educational programs outside of the hospital setting and the 80-hour workweek. Such a program is easily implemented, highly effective, and well received. This format has the added benefit of improving interaction between faculty and residents and increasing the camaraderie of a surgical training program.

Virtual reality (VR) technology has gained importance in many areas of medicine. Knowledge concerning the application and the influence of VR-enhanced exercise programs is limited for patients receiving coronary artery bypass grafting. The purpose of this study was to evaluate the effect of a virtual "country walk" on the number of sessions necessary to reach cardiac rehabilitation goals in patients undergoing coronary artery bypass grafting. Twenty subjects who were seen for cardiac rehabilitation between January and June 2004 comprised the study sample. The protocol for this study included an initial maximum graded exercise tolerance test, given to determine the subsequent training goals for the subject, followed by biweekly submaximal endurance training sessions. All subjects were assigned by lot to 1 of 2 submaximal endurance training programs, one (group 2) with and the other (group 1) without the added VR environment. In all other respects, the 2 programs were identical. Each training session lasted for 30 minutes and was carried out twice per week for about 3 months. The primary outcome measures were maximum load during the work sessions, target oxygen consumption, target heart rate (beats per minute), and number of training sessions required to reach rehabilitation goals. By the end of 20 training sessions, only 4 of the 10 control subjects had reached the heart rate target goal of 85% their maximum heart rate. In contrast, 9 of the 10 subjects in the VR program had attained this goal by 9 or fewer training sessions. When target metabolic cost (75% peak oxygen consumption) was used as the training goal, all 10 subjects in the VR program had reached this target after 2 training sessions (or, in some cases, 1 training session), but not until training session 15 did a cumulative number of 9 control subjects reach this goal. These study outcomes clearly support the notion that incorporating a VR environment into cardiac rehabilitation programs will accelerate maximum recovery of patients' cardiovascular function.

The seasonal budgets and evolution of photochemical oxidants reported for greater Ravenna's urban-industrial area in the present study were calculated using the combined data from on-site systematic surveys (1978-1989) and from the monitoring network of the local environmental authorities. The notable differences in the concentrations of ozone and nitrogen oxides depended on season, and meteorological variables showed a marked correlation to the seasonal budget of trace constituents. The weak local circulation, the land-sea breeze system, and high solar radiation in summer, which may persist at length because of the anticyclonic conditions, can produce episodes of intense photochemical reactions. In winter, by contrast, low solar radiation and the absence of the breeze system results in very different evolutions of both pollutant concentrations and their seasonal budget.

Hardison, Mark E.

2017-01-01

Work-related musculoskeletal disorders are a significant burden; however, no consensus has been reached on how to maximize occupational rehabilitation programs for people with these disorders, and the impact of simulating work tasks as a mode of intervention has not been well examined. In this retrospective cohort study, the authors used logistic regression to identify client and program factors predicting success for 95 clients in a general occupational rehabilitation program and 71 clients in a comprehensive occupational rehabilitation program. The final predictive model for general rehabilitation included gender, number of sessions completed, and performance of work simulation activities. Maximum hours per session was the only significant predictor of success in the comprehensive rehabilitation program. This study identifies new factors associated with success in occupational rehabilitation, specifically highlighting the importance of intensity (i.e., session length and number of sessions) of therapy and occupation-based activities for this population.

Point-of-Care Programming for Neuromodulation: A Feasibility Study Using Remote Presence.

PubMed

Mendez, Ivar; Song, Michael; Chiasson, Paula; Bustamante, Luis

2013-01-01

The expansion of neuromodulation and its indications has resulted in hundreds of thousands of patients with implanted devices worldwide. Because all patients require programming, this growth has created a heavy burden on neuromodulation centers and patients. Remote point-of-care programming may provide patients with real-time access to neuromodulation expertise in their communities. To test the feasibility of remotely programming a neuromodulation device using a remote-presence robot and to determine the ability of an expert programmer to telementor a nonexpert in programming the device. A remote-presence robot (RP-7) was used for remote programming. Twenty patients were randomly assigned to either conventional programming or a robotic session. The expert remotely mentored 10 nurses with no previous experience to program the devices of patients assigned to the remote-presence sessions. Accuracy of programming, adverse events, and satisfaction scores for all participants were assessed. There was no difference in the accuracy or clinical outcomes of programming between the standard and remote-presence sessions. No adverse events occurred in any session. The patients, nurses, and the expert programmer expressed high satisfaction scores with the remote-presence sessions. This study establishes the proof-of-principle that remote programming of neuromodulation devices using telepresence and expert telementoring of an individual with no previous experience to accurately program a device is feasible. We envision a time in the future when patients with implanted devices will have real-time access to neuromodulation expertise from the comfort of their own home.

Range-Specific High-Resolution Mesoscale Model Setup: Data Assimilation

NASA Technical Reports Server (NTRS)

Watson, Leela R.

2014-01-01

Mesoscale weather conditions can have an adverse effect on space launch, landing, and ground processing at the Eastern Range (ER) in Florida and Wallops Flight Facility (WFF) in Virginia. During summer, land-sea interactions across Kennedy Space Center (KSC) and Cape Canaveral Air Force Station (CCAFS) lead to sea breeze front formation, which can spawn deep convection that can hinder operations and endanger personnel and resources. Many other weak locally driven low-level boundaries and their interactions with the sea breeze front and each other can also initiate deep convection in the KSC/CCAFS area. Some of these other boundaries include the Indian River breeze front, Banana River breeze front, outflows from previous convection, horizontal convective rolls, convergence lines from other inland bodies of water such as Lake Okeechobee, the trailing convergence line from convergence of sea breeze fronts due to the shape of Cape Canaveral, frictional convergence lines from the islands in the Bahamas, convergence lines from soil moisture differences, convergence lines from cloud shading, and others. All these subtle weak boundary interactions often make forecasting of operationally important weather very difficult at KSC/CCAFS during the convective season (May-Oct). These convective processes often build quickly, last a short time (60 minutes or less), and occur over small distances, all of which also poses a significant challenge to the local forecasters who are responsible for issuing weather advisories, watches, and warnings. Surface winds during the transition seasons of spring and fall pose the most difficulties for the forecasters at WFF. They also encounter problems forecasting convective activity and temperature during those seasons. Therefore, accurate mesoscale model forecasts are needed to aid in their decision making. Both the ER and WFF would benefit greatly from high-resolution mesoscale model output to better forecast a variety of unique weather phenomena. Global and national scale models cannot properly resolve important local-scale weather features at each location due to their horizontal resolutions being much too coarse. Therefore, a properly tuned model at a high resolution is needed to provide improved capability. This task is a multi-year effort in which the Applied Meteorology Unit (AMU) will tune the Weather Research and Forecasting (WRF) model individually for each range. The goal of the first year, the results of which are in this report, was to tune the WRF model based on the best model resolution and run time while using reasonable computing capabilities. To accomplish this, the ER and WFF supported the tasking of the AMU to perform a number of sensitivity tests in order to determine the best model configuration for operational use at each of the ranges to best predict winds, precipitation, and temperature (Watson 2013). This task is a continuation of that work and will provide a recommended local data assimilation (DA) and numerical forecast model design optimized for the ER and WFF to support space launch activities. The model will be optimized for local weather challenges at both ranges.

On behalf of the Subsurface Biogeochemical Research (SBR) program managers in the Climate and Environmental Sciences Division (CESD), Office of Biological and Environmental Research (BER), welcome to the 2011 SBR Principal Investigators meeting. Thank you in advance for your attendance and your presentations at this year's meeting. As the events in Japan continue to unfold, we are all reminded that the research we perform on radionuclide behavior in the environment has implications beyond legacy waste cleanup and in fact has its place in the discussion on the expanded use of nuclear power. As in the past, there are three broadmore » objectives to the Principal Investigators meeting: (1) to provide opportunities to share research results and promote interactions among the SBR scientists and other invited guests; (2) to evaluate the progress of each project within the program; and (3) to showcase the scientific expertise and research progress over the past year to senior managers within the DOE Office of Science, the technology offices within DOE, and other invited attendees from other Federal Agencies. This past year has seen a few significant changes within BER and within the SBR program. In November, our Associate Director for BER, Anna Palmisano, retired from Federal service. Just this month, Dr. Sharlene Weatherwax (Division Director for Biological Systems Sciences) has been named as the new Associate Director for BER. In August, BER welcomed Dr. Gary Geernaert as the new Division Director for CESD. Gary joins the division from Los Alamos National Laboratory with a background in atmospheric science. Within the SBR program, a new Strategic Plan was completed last June (currently posted on the SBR and the Office of Science website). The new strategic plan is intended to foster integration within the Environmental Systems Science portion of the BER budget that includes both SBR and Terrestrial Ecosystem Sciences (TES). Both these programs share a goal of advancing a predictive understanding of environmental processes and utilizing iterative, multidisciplinary approaches to understand complex environmental systems of relevance to DOE. CESD in general is undergoing continued discussions on integration among its programs in an effort to develop a new strategic plan for the division. This effort also includes identifying opportunities for integration with BER's Biological Systems Science Division (BSSD). The program this year includes three poster presentation sessions, six plenary sessions, and three breakout sessions. The plenary session on Tuesday morning will feature introductory presentations by BER program staff and three keynote addresses from Dr. Ken Bencala (USGS), Dr. Michael (Mick) Follows (MIT) and Dr. Sue Brantley (PSU) that will lead into three breakout sessions Tuesday afternoon. The breakout sessions are intended to highlight key developments in SBR research and foster a dialog among session participants on scientific paths forward in each particular area. The SBR program managers are asking for input from the SBR community at these sessions to help guide future efforts and/or identify areas of integration within BER programs. On Wednesday, plenary sessions will continue in the morning, followed by an early afternoon poster session. After an extended break for lunch, plenary sessions will continue in the afternoon, followed by an evening poster session. Thursday's plenary session will focus on selected highlights of research efforts at the IFRC sites and on a new potential TES field effort in the Arctic. This new field site is an obvious point of integration between the SBR and TES programs.« less

The monsoon system: Land-sea breeze or the ITCZ?

NASA Astrophysics Data System (ADS)

Gadgil, Sulochana

2018-02-01

For well over 300 years, the monsoon has been considered to be a gigantic land-sea breeze driven by the land-ocean contrast in surface temperature. In this paper, this hypothesis and its implications for the variability of the monsoon are discussed and it is shown that the observations of monsoon variability do not support this popular theory of the monsoon. An alternative hypothesis (whose origins can be traced to Blanford's (1886) remarkably perceptive analysis) in which the basic system responsible for the Indian summer monsoon is considered to be the Intertropical Convergence Zone (ITCZ) or the equatorial trough, is then examined and shown to be consistent with the observations. The implications of considering the monsoon as a manifestation of the seasonal migration of the ITCZ for the variability of the Indian summer monsoon and for identification of the monsoonal regions of the world are briefly discussed.

In 2009 and 2011, the MOSO I and MOSO II meteorological field experiments took place in SW-Iceland. The main objectives were to describe the low level atmospheric coastal flows in the vicinity of mountains. The observations for the MOSO dataset were made using a large number of automatic weather stations, microbarographs, radiosoundings and a remotely piloted aircraft. The highlights of the findings include a four-dimensional description of the sea-breeze in Iceland, weak downslope acceleration, summer- and winter-time mountain wake flow, transition between wake flow and sea-breeze. The orographic drag force is explored and shown to be not so high most of the time in the predicted high-drag state. The observations from the remotely piloted aircraft have been used successfully to nudge simulations of the flow and are shown to be promising for operational use in numerical prediction of mesoscale coastal and orographic flows.

The inland boundary layer at low latitudes

NASA Astrophysics Data System (ADS)

Garratt, J. R.

1985-08-01

Observations from the Koorin boundary-layer experiment in Australia (latitude 16 °S) were analysed in a study of the nocturnal jet development. For geostrophic winds in the range 10 20 m s-1, ageostrophic wind magnitudes of 5 10m s-1 were common above the surface layer near sunset, with cross-isobar flow angles of about 40 °. The jet that then developed by midnight was probably the result of these large ageostrophic winds, strong surface cooling and favourable baroclinity and sloping terrain. The analysis is supported by numerical model calculations with special emphasis on the role of long-wave radiative cooling on turbulent decay. Decay is rapid in the presence of radiation, although there is little influence on stress divergence levels. Evidence of sea-breeze influences on the jet evolution, and on features of deeply penetrating sea breezes in general, will be presented and discussed in part 2 of this study (submitted to Boundary-Layer Meteorol.).

The aim of this study was to evaluate the radiopacity of eight contemporary luting cements using direct digital radiography. Ten specimens, (5 mm diameter, 1 mm high) were prepared for each material tested (RelyX ARC, RelyX U100, RelyX Unicem, Nexus 2, Nexus 3, Metacem, Breeze, Adhesor zinc phosphate). The specimens were stored in a moist chamber at 37°C until completely set, then radiographed using a Kodak digital sensor and an aluminum step wedge with variable thicknesses (1 to 13 mm in 1-mm increments) used for reference. A Kodak 2100 intraoral X-ray unit was operated at 60 kV, 7 mA, and 0.20 seconds. According to international standards, the radiopacity of the specimens was compared with that of the aluminum step wedge using the equal-density area tool of the Kodak Dental Imaging software (ver. 6.7). Data were analyzed by ANOVA and Tukey's test. Adhesor zinc phosphate cement showed the highest radiopacity of all materials and dentin. Breeze showed the lowest radiopacity (p < 0.05). No significant difference in radiopacity was observed between dentin and RelyX ARC, Nexus 2, or Metacem (p > 0.05). The radiopacities of Nexus 3 and RelyX Unicem were significantly higher than those of other resin cements and dentin (p < 0.05). All materials showed radiopacity above the minimum recommended by the International Organization for Standardization and the American National Standards/American Dental Association. Breeze had less radiopacity than dentin. © 2012 by the American College of Prosthodontists.

The influence of terrain forcing on the initiation of deep convection over Mediterranean islands

NASA Astrophysics Data System (ADS)

Barthlott, Christian; Kirshbaum, Daniel

2013-04-01

The influence of mountainous islands on the initiation of deep convection is investigated using the Consortium for Small-scale Modeling (COSMO) model. The study day is 26 August 2009 on which moist convection occurred over both the Corsica and Sardinia island in the Mediterranean Sea. Sensitivity runs with systematically modified topography are explored to evaluate the relative importance of the land-sea contrast and the terrain height for convection initiation. Whereas no island precipitation is simulated when the islands are completely removed, all simulations that represent these land surfaces develop convective precipitation. Although convection initiates progressively earlier in the day over taller islands, the precipitation rates and accumulations do not show a fixed relationship with terrain height. This is due to the competing effects of different physical processes. First, whereas the forcing for low-level ascent increases over taller islands, the boundary-layer moisture supply decreases, which diminishes the conditional instability and precipitable water. Second, whereas taller islands enhance the inland propagation speeds of sea-breeze fronts, they also mechanically block these fronts and prevent them from reaching the island interior. As a result, the island precipitation is rather insensitive to island terrain height except for one particular case in which the island precipitation increases considerably due to an optimal superposition of the sea breeze and upslope flow. These results demonstrate the complexity of interactions between sea breezes and orography and reinforce that an adequate representation of detailed topographic features is necessary to account for thermally induced wind systems that initiate deep convection.

An Israeli haboob: Sea breeze activating local anthropogenic dust sources in the Negev loess

NASA Astrophysics Data System (ADS)

Crouvi, Onn; Dayan, Uri; Amit, Rivka; Enzel, Yehouda

2017-02-01

Meso-scale weather systems, such as convective haboobs, are considered to be an important dust generation mechanism. In Israel, however, rather than of meso-scale weather systems, most dust storms are generated by synoptic-scale systems, originating from Sahara and Arabia. Consequently, only distal sources of suspended and deposited dust in Israel are currently reported. Here we report the first detailed study on the merging of synoptic- and meso-scale weather systems leading to a prominent dust outbreak over the Negev, Israel. During the afternoon of May 2nd, 2007, a massive dust storm covered the northern Negev, forming a one kilometer high wall of dust. The haboob was associated with PM10 concentrations of 1000-1500 μg m-3 that advanced at a speed of 10-15 m s-1 and caused temporary closure of local airports. In contrast to most reported haboobs, this one was generated by a sea breeze front acting as a weak cold front enhanced by a cold core cyclone positioned over Libya and Egypt. The sea breeze that brought cold and moist marine air acted as a gravity current with strong surface winds. The sources for the haboob were the loessial soils of the northwestern Negev, especially agricultural fields that were highly disturbed in late spring to early summer. Such surface disturbance is caused by agricultural and/or intensive grazing practices. Our study emphasizes the importance of local dust sources in the Negev and stresses loess recycling as an important process in contemporary dust storms over Israel.

The Implementation and Evaluation of the Emergency Response Dose Assessment System (ERDAS) at Cape Canaveral Air Station/Kennedy Space Center

NASA Technical Reports Server (NTRS)

Evans, Randolph J.; Tremback, Craig J.; Lyons, Walter A.

1996-01-01

The Emergency Response Dose Assessment System (ERDAS) is a system which combines the mesoscale meteorological prediction model RAMS with the diffusion models REEDM and HYPACT. Operators use a graphical user interface to run the models for emergency response and toxic hazard planning at CCAS/KCS. The Applied Meteorology Unit has been evaluating the ERDAS meteorological and diffusion models and obtained the following results: (1) RAMS adequately predicts the occurrence of the daily sea breeze during non-cloudy conditions for several cases. (2) RAMS shows a tendency to predict the sea breeze to occur slightly earlier and to move it further inland than observed. The sea breeze predictions could most likely be improved by better parameterizing the soil moisture and/or sea surface temperatures. (3) The HYPACT/REEDM/RAMS models accurately predict launch plume locations when RAMS winds are accurate and when the correct plume layer is modeled. (4) HYPACT does not adequately handle plume buoyancy for heated plumes since all plumes are presently treated as passive tracers. Enhancements should be incorporated into the ERDAS as it moves toward being a fully operational system and as computer workstations continue to increase in power and decrease in cost. These enhancements include the following: activate RAMS moisture physics; use finer RAMS grid resolution; add RAMS input parameters (e.g. soil moisture, radar, and/or satellite data); automate data quality control; implement four-dimensional data assimilation; modify HYPACT plume rise and deposition physics; and add cumulative dosage calculations in HYPACT.

Forster, J L; Jeffery, R W; Sullivan, S; Snell, M K

1985-11-01

In a work-site weight control program using a self-motivational program of financial incentives implemented through payroll deduction, 131 university employees chose weight loss goals (0 to 60 lb) and incentives (+5 to +30) to be deducted from each paycheck for six months. Return of incentive money was contingent on progress toward weight goals. Participants were assigned randomly to one of four protocols, involving group educational sessions v self-instruction only and required v optional attendance at weigh-ins and sessions. Overall, dropout rates (21.4%) and mean weight loss (12.2 lb) were encouraging, especially compared with those of other work-site programs. Weight loss was positively associated with attendance at weigh-ins and educational sessions. However, requiring attendance did not increase program effectiveness and seemed also to discourage enrollment among men. The weight control program was equally effective when offered with professionally led educational sessions or when accompanied by self-instructional materials only.

The experience of sessional teachers in nursing: A qualitative study.

Dixon, Kathleen A; Cotton, Antoinette; Moroney, Robyn; Salamonson, Yenna

2015-11-01

Worldwide, there is a growing reliance on sessional teachers in universities. This trend is reflected in an undergraduate nursing program in a large Australian metropolitan university where a significant proportion of contact hours is staffed by sessional teachers, yet little is known about what type of support is needed for sessional teachers to optimise their capacity to contribute to the academic program. To describe the experiences of sessional teachers in a Bachelor of Nursing program in an Australian university. This is an exploratory qualitative study; fifteen sessional teachers were interviewed using semi-structured questions to explore their experiences of teaching. This study was conducted in a large metropolitan school of nursing located on three sites. A purposive sample of 15 sessional teachers was interviewed for this study. Semi-structured interviews were conducted face to face. Thematic analysis was used to identify major themes in the interview data and collaborative analysis was undertaken to ensure rigour. Findings revealed that sessional teachers enjoyed teaching, were committed to their role and viewed their clinical currency as a valuable asset for teaching. However, participants also spoke about wanting a sense of belonging to the School, with most feeling they were "outsiders". Areas identified for improvement included system and process issues, micro teaching and assessment skills, classroom management and timely access to resources. There is a need to improve sessional teachers' sense of belonging and to provide an inclusive structure and culture to optimise their capacity to contribute to the academic program.

2013-10-01

The objectives of this study were to: (a) estimate the costs of providing a single-session HIV prevention intervention and a multi-session intervention, and (b) estimate the number of HIV transmissions that would need to be prevented for the intervention to be cost-saving or cost-effective (threshold analysis). Project START was evaluated with 522 young men aged 18-29 years released from eight prisons located in California, Mississippi, Rhode Island, and Wisconsin. Cost data were collected prospectively. Costs per participant were $689 for the single-session comparison intervention, and ranged from $1,823 to 1,836 for the Project START multi-session intervention. From the incremental threshold analysis, the multi-session intervention would be cost-effective if it prevented one HIV transmission for every 753 participants compared to the single-session intervention. Costs are comparable with other HIV prevention programs. Program managers can use these data to gauge costs of initiating these HIV prevention programs in correctional facilities.

To describe the development of a cadaver-based educational program and report our residents' assessment of the new program. An anatomy-based educational program was developed using fresh frozen cadavers to teach surgical anatomy and operative skills to general surgery (GS) trainees. Residents were asked to complete a voluntary, anonymous survey evaluating perceptions of the program (6 questions formulated on a 5-point Likert scale) and comparing cadaver sessions to other types of learning (4 rank order questions). Large university teaching hospital. Medical students, residents, and faculty members were participants in the cadaver programs. Only GS residents were asked to complete the survey. Since its implementation, 150 residents of all levels participated in 13 sessions. A total of 40 surveys were returned for a response rate of 89%. Overall, respondents held a positive view of the cadaver sessions and believed them to be useful for learning anatomy (94% agree or strongly agree), learning the steps of an operation (76% agree or strongly agree), and increasing confidence in doing an operation (53% agree or strongly agree). Trainees wanted to have more sessions (87% agree or strongly agree), and believed they would spend free time in the cadaver laboratory (58% agree or strongly agree). Compared with other learning modalities, cadaver sessions were ranked first for learning surgical anatomy, followed by textbooks, simulators, web sites, animate laboratories, and lectures. Respondents also ranked cadaver sessions first for increasing confidence in performing a procedure and for learning the steps of an operation. Cost of cadavers represented the major expense of the program. Fresh cadaver dissections represent a solution to the challenges of efficient, safe, and effective general surgery education. Residents have a positive attitude toward these teaching sessions and found them to be more effective than other learning modalities. Copyright © 2012 Association of Program Directors in Surgery.

1988-01-01

Program Review VI was comprised of six sessions, including an opening session, four technical sessions that addressed each of the major DOE research areas, and a session on special issues. The technical sessions were on Hydrothermal, Hot Dry Rock, Geopressured and Magma resources. Presenters in the technical sessions discussed their R and D activities within the context of specific GTD Programmatic Objectives for that technology, their progress toward achieving those objectives, and the value of those achievements to industry. The ''Special Issues'' presentations addressed several topics such as the interactions between government and industry on geothermal energy R and D;more » the origin and basis for the programmatic objectives analytical computer model; and international marketing opportunities for US geothermal equipment and services. The unique aspect of Program Review VI was that it was held in conjunction with the National Geothermal Association's Industry Round Table on Federal R and D. The Round Table provided a forum for open and lively discussions between industry and government researchers and gave industry an opportunity to convey their needs and perspectives on DOE's research programs. These discussions also provided valuable information to DOE regarding industry's priorities and directions.« less

The purpose of the Community Alliance for Research Empowering Social change (CARES) training program was to (1) train community members on evidence-based public health, (2) increase their scientific literacy, and (3) develop the infrastructure for community-based participatory research (CBPR). We assessed participant knowledge and evaluated participant satisfaction of the CARES training program to identify learning needs, obtain valuable feedback about the training, and ensure learning objectives were met through mutually beneficial CBPR approaches. A baseline assessment was administered before the first training session and a follow-up assessment and evaluation was administered after the final training session. At each training session a pretest was administered before the session and a posttest and evaluation were administered at the end of the session. After training session six, a mid-training evaluation was administered. We analyze results from quantitative questions on the assessments, pre- and post-tests, and evaluations. CARES fellows knowledge increased at follow-up (75% of questions were answered correctly on average) compared with baseline (38% of questions were answered correctly on average) assessment; post-test scores were higher than pre-test scores in 9 out of 11 sessions. Fellows enjoyed the training and rated all sessions well on the evaluations. The CARES fellows training program was successful in participant satisfaction and increasing community knowledge of public health, CBPR, and research methodology. Engaging and training community members in evidence-based public health research can develop an infrastructure for community-academic research partnerships.

To assess use of the combined just-in-time teaching (JiTT) and peer instruction (PI) instructional strategy in a residency program's core curriculum. In 2010-2011, JiTT/PI was piloted in 31 core curriculum sessions taught by 22 faculty in the Northwestern University Feinberg School of Medicine's general surgery residency program. JiTT/PI required preliminary and categorical residents (n=31) to complete Web-based study questions before weekly specialty topic sessions. Responses were examined by faculty members "just in time" to tailor session content to residents' learning needs. In the sessions, residents answered multiple-choice questions (MCQs) using clickers and engaged in PI. Participants completed surveys assessing their perceptions of JiTT/PI. Videos were coded to assess resident engagement time in JiTT/PI sessions versus prior lecture-based sessions. Responses to topic session MCQs repeated in review sessions were evaluated to study retention. More than 70% of resident survey respondents indicated that JiTT/PI aided in the learning of key points. At least 90% of faculty survey respondents reported positive perceptions of aspects of the JiTT/PI strategy. Resident engagement time for JiTT/PI sessions was significantly greater than for prior lecture-based sessions (z=-2.4, P=.016). Significantly more review session MCQ responses were correct for residents who had attended corresponding JiTT/PI sessions than for residents who had not (chi-square=13.7; df=1; P<.001). JiTT/PI increased learner participation, learner retention, and the amount of learner-centered time. JiTT/PI represents an effective approach for meaningful and active learning in core curriculum sessions.

To describe the challenges associated with the development and assessment of an obstetric emergency team simulation program. The goal was to develop a hybrid, in-situ and high fidelity obstetric emergency team simulation program that incorporated weekly simulation sessions on the labor and delivery unit, and quarterly, education protected sessions in the simulation center. All simulation sessions were video-recorded and reviewed. Labor and delivery unit and simulation center. Medical staff covering labor and delivery, anesthesiology and obstetric residents and obstetric nurses. Assessments included an on-line knowledge multiple-choice questionnaire about the simulation scenarios. This was completed prior to the initial in-situ simulation session and repeated 3 months later, the Clinical Teamwork Scale with inter-rater reliability, participant confidence surveys and subjective participant satisfaction. A web-based curriculum comprising modules on communication skills, team challenges, and team obstetric emergency scenarios was also developed. Over 4 months, only 6 labor and delivery unit in-situ sessions out of a possible 14 sessions were carried out. Four high-fidelity sessions were performed in 2 quarterly education protected meetings in the simulation center. Information technology difficulties led to the completion of only 18 pre/post web-based multiple-choice questionnaires. These test results showed no significant improvement in raw score performance from pre-test to post-test (P=.27). During Clinical Teamwork Scale live and video assessment, trained raters and program faculty were in agreement only 31% and 28% of the time, respectively (Kendall's W=.31, P<.001 and W=.28, P<.001). Participant confidence surveys overall revealed confidence significantly increased (P<.05), from pre-scenario briefing to after post-scenario debriefing. Program feedback indicates a high level of participant satisfaction and improved confidence yet further program refinement is required. Copyright © 2016 Elsevier Inc. All rights reserved.

Salt intake of schoolchildren in the Australian state of Victoria is high. To protect future cardiovascular health, interventions that seek to reduce the amount of salt in children's diets are required. We sought to develop and pilot test a Web-based program (Digital Education to Limit Salt Intake in the Home [DELISH]) that aims to reduce dietary salt intake among schoolchildren and to improve child and parent knowledge, attitudes, and behaviors related to salt intake. This paper presents the DELISH study protocol, along with pilot findings used to inform the development of the program. The DELISH program is a 5-week Web-based intervention that targets schoolchildren aged 7-10 years and their parents. This is a single-arm study with a pretest and posttest design. We will assess change in salt intake through analysis of 24-hour urinary sodium excretion. Children and parents will complete online surveys assessing knowledge, attitudes, and behaviors related to salt intake. We will assess feasibility of the program via process measures, which include metrics to describe intervention uptake (eg, number of children who complete Web-based sessions and of parents who view online newsletters) and evaluation surveys and interviews conducted with children, parents, and schoolteachers. The first 2 Web sessions developed for children were pilot tested in 19 children aged 8-12 years. Findings from pilot testing indicated that most children (session 1: 18/19, 95%; and session 2: 19/19, 100%) enjoyed completing each session and liked the inclusion of comic strips and interactive games. Commonly reported areas of improvement related to sessions being text and content heavy. Based on these findings, we simplified sessions and developed 3 additional sessions for use in the DELISH program. The DELISH program was implemented during June-December 2016. We expect to have results from this study at the end of 2017. To our knowledge, this is the first Australian study to examine the effectiveness of a Web-based program to reduce salt intake among children in primary school. If shown to be acceptable and effective in lowering salt intake, the DELISH program could be tested using a more rigorous randomized controlled trial design. ©Carley Ann Grimes, Alison Booth, Durreajam Khokhar, Madeline West, Claire Margerison, Karen Campbell, Caryl Nowson.

Lotter, Christine R.; Miller, Cory

In this paper, we explore middle school science teachers' learning of inquiry-based instructional strategies through reflection on practice teaching sessions during a summer enrichment program with middle level students. The reflection sessions were part of a larger year-long inquiry professional development program in which teachers learned science content and inquiry pedagogy. The program included a 2-week summer institute in which teachers participated in science content sessions, practice teaching to middle level students, and small group-facilitated reflection sessions on their teaching. For this study, data collection focused on teachers' recorded dialogue during the facilitator - run reflection sessions, the teachers' daily written reflections, a final written reflection, and a written reflection on a videotaped teaching session. We investigated the teachers' reflection levels and the themes teachers focused on during their reflection sessions. Teachers were found to reflect at various reflection levels, from simple description to a more sophisticated focus on how to improve student learning. Recurrent themes point to the importance of providing situated learning environments, such as the practice teaching with immediate reflection for teachers to have time to practice new instructional strategies and gain insight from peers and science educators on how to handle student learning issues.

Six teachers' experience with a video-based professional development program: Its implementation and development

NASA Astrophysics Data System (ADS)

Nelson, Marianne T.

Many professional development programs fall short of accomplishing their objectives. Recently, programs have been developed that would appear to appeal to teachers and to enhance their potential to influence teachers' practice. My research describes six teachers' responses to a professional development program that employs video as a key feature. The Next Move program consists of eight two-hour sessions, and includes a one-hour video intended to stimulate discussion among a group of teachers. All group participants were invited to participate in the study. My interview sample consisted of six teachers from two groups who volunteered to participate in the study. The first group consisted of four study participants from an urban district. Twelve teachers from this district attended the initial session. Of these, seven became regular participants who completed all sessions. Most of them registered for the graduate credit option. Two study participants were from a single suburban elementary school that had five teachers; they occasionally met jointly with a group from another elementary school, so the numbers varied. Teachers volunteering for this study had from four to seventeen years experience. They were all Caucasian and included four women and two men. My data set consists of three interviews with each teacher, one at the start of the program, one after the last session, and one at the end of the school year. I interviewed each facilitator and jointly interviewed the program's producer and project manager. Additional data was obtained from observation of program sessions and classrooms. Print data sources were the program guide and the project summative evaluation. The data analysis suggests a poor match between the funder's intent and what the teachers expected, based on the program title and information in the promotional flyer. Because of these discontinuities, the program failed to meet its objectives fully. However, some interesting benefits did appear. For example, the classroom clips did focus teachers' discussion on pedagogical issues. Each participant, over the short duration of the study, did implement at least one program idea, and several teachers mentioned continuing conversations they had begun during program sessions.

The NASA Propagation Experimenters (NAPEX) meeting is convened each year to discuss studies supported by the NASA Propagation Program. Representatives from the satellite communications industry, academia and government who have an interest in space-ground radio wave propagation are invited to NAPEX meetings for discussions and exchange of information. The reports delivered at this meeting by program managers and investigators present recent activities and future plans. This forum provides an opportunity for peer discussion of work in progress, timely dissemination of propagation results, and close interaction with the satellite communications industry. NAPEX XXI took place in El Segundo, California on June 11-12, 1997 and consisted of three sessions. Session 1, entitled "ACTS Propagation Study Results & Outcome " covered the results of 20 station-years of Ka-band radio-wave propagation experiments. Session 11, 'Ka-band Propagation Studies and Models,' provided the latest developments in modeling, and analysis of experimental results about radio wave propagation phenomena for design of Ka-band satellite communications systems. Session 111, 'Propagation Research Topics,' covered a diverse range of propagation topics of interest to the space community, including overviews of handbooks and databases on radio wave propagation. The ACTS Propagation Studies miniworkshop was held on June 13, 1997 and consisted of a technical session in the morning and a plenary session in the afternoon. The morning session covered updates on the status of the ACTS Project & Propagation Program, engineering support for ACTS Propagation Terminals, and the Data Center. The plenary session made specific recommendations for the future direction of the program.

Pupils teach to pupils about genetics or global warming

NASA Astrophysics Data System (ADS)

Cuny, Delphine

2013-04-01

The idea of this project is to put pupils in a teaching situation. Classes of teenagers go to primary schools and animate a science workshop. Junior pupils are separated in small groups and they attend two different sessions in the same half-day. The whole workshop consists of 4 sessions. Each session is organized with an activity (microscope observation, counting of chromosomes, drawing of a curve, etc.) in which senior pupils coach the younger, and ends with a debate or an assessment. The first experiment of this type of project was realized with a class of 14 to 15 year old pupils on the theme: How do your parents transmit your characteristics? The four sessions are attended in disorder but when knowledge of other sessions are necessary, senior pupils explain them at the beginning of the session. Junior pupils have a notebook to write their activities and to note their conclusions. Session 1: What did my father give to make me? Drawing and measuring microscopic observations of human spermatozoons. Conclusion: my father gave a spermatozoon which measures less than one mm long, this spermatozoon met my mother's egg and it made my first cell. Session 2: What does the program that made me look like? Microscope observation of blood cells, identification of chromosomes in the core. On microscope pictures, counting of chromosomes. Conclusion: My program is in each cell of my body, inside the core. Sometimes, in this core, we can observe short sticks that are called chromosomes. All human beings have the same number of chromosomes in their cells: 46. Session 3: Where do my chromosomes come from? Counting of chromosomes in spermatozoons or ovums and playing with sets of chromosomes to deduct sex of a baby. Conclusion: Daddy gave me 23 chromosomes and mummy gave me 23 chromosomes too. My program is then constituted from half of daddy's program and half of mummy's program. My brothers and sisters also have half and half, but not the same halves! Session 4: Where is the program that made me situated? Virtual experiments on the first cell of rats (core transfers) Conclusion: The program that made that a rat is itself is situated in the core of its first cell. It is called a genetic program. Second experiment of this type of project is realized with a class of 16-17 year old pupils, on global warming for 8 to 11 year old pupils from the neighbor school. The older pupils use a teaching set created by "la main à la pâte" foundation, the set is called "le climat, ma planète et moi" (the climate, my planet and me, http://www.fondation-lamap.org/fr/climat). This project is to take place in March 2013.

Temperature And Wind Velocity Oscillations Along a Gentle Slope During Sea-Breeze Events

NASA Astrophysics Data System (ADS)

Bastin, Sophie; Drobinski, Philippe

2005-03-01

The flow structure on a gentle slope at Vallon d’Ol in the northern suburbs of Marseille in southern France has been documented by means of surface wind and temperature measurements collected from 7 June to 14 July 2001 during the ESCOMPTE experiment. The analysis of the time series reveals temperature and wind speed oscillations during several nights (about 60--90 min oscillation period) and several days (about 120-180 min oscillation period) during the whole observing period. Oscillating katabatic winds have been reported in the literature from theoretical, experimental and numerical studies. In the present study, the dynamics of the observed oscillating katabatic winds are in good agreement with the theory.In contrast to katabatic winds, no daytime observations of oscillating anabatic upslope flows have ever been published to our knowledge, probably because of temperature inversion break-up that inhibits upslope winds. The present paper shows that cold air advection by a sea breeze generates a mesoscale horizontal temperature gradient, and hence baroclinicity in the atmosphere, which then allows low-frequency oscillations, similar to a katabatic flow. An expression for the oscillation period is derived that accounts for the contribution of the sea-breeze induced mesoscale horizontal temperature gradient. The theoretical prediction of the oscillation period is compared to the measurements, and good agreement is found. The statistical analysis of the wind flow at Vallon d’Ol shows a dominant north-easterly to easterly flow pattern for nighttime oscillations and a dominant south-westerly flow pattern for daytime oscillations. These results are consistent with published numerical simulation results that show that the air drains off the mountain along the maximum slope direction, which in the studied case is oriented south-west to north-east.

Investigation of the atmospheric boundary layer dynamics during the ESCOMPTE campaign

This paper presents some results about the behavior of the atmospheric boundary layer observed during the ESCOMPTE experiment. This campaign, which took place in south-eastern France during summer 2001, was aimed at improving our understanding of pollution episodes in relation to the dynamics of the lower troposphere. Using a large data set, as well as a simulation from the mesoscale non-hydrostatic model Meso-NH, we describe and analyze the atmospheric boundary layer (ABL) development during two specific meteorological conditions of the second Intensive Observation Period (IOP). The first situation (IOP2a, from 22 June to 23 June) corresponds to moderate, dry and cold northerly winds (end of Mistral event), coupled with a sea-breeze in the lower layer, whereas sea-breeze events with weak southerly winds occurred during the second part of the period (IOP2b, from 24 June to 26 June). In this study, we first focus on the validation of the model outputs with a thorough comparison of the Meso-NH simulations with fields measurements on three days of the IOP: 22 June, 23 June and 25 June. We also investigate the structure of the boundary layer on IOP2a when the Mistral is superimposed on a sea breeze. Then, we describe the spatial and diurnal variability of the ABL depths over the ESCOMPTE domain during the whole IOP. This step is essential if one wants to know the depth of the layer where the pollutants can be diluted or accumulated. Eventually, this study intends to describe the ABL variability in relation to local or mesoscale dynamics and/or induced topographic effects, in order to explain pollution transport processes in the low troposphere.

City-scale warming is becoming a serious problem in terms of human health. Urban green spaces are expected to act as a countermeasure for urban warming, and therefore better understanding of the micro-climate benefits of urban green is needed. This study quantified the thermal influence of a large green park in Tokyo, Japan on the surrounding urban area by collecting long-term measurements. Apparent variations in the temperature difference between the park and surrounding town were found at both the diurnal and seasonal scales. Advection by regional-scale wind and turbulent mixing transfers colder air from the park to urban areas in its vicinity. The extent of the park's thermal influence on the town was greater on the downwind side of the park (450 m) than on the upwind side (65 m). The extent was also greater in an area where the terrain slopes down toward the town. Even on calm nights, the extent of the thermal influence extended by the park breeze to an average of 200 m from the park boundary. The park breeze was characterized by its divergent flow in a horizontal plane, which was found to develop well in calm conditions late at night (regional scale wind <1.5 m s and after 02:00 LST). The average magnitude of the cooling effect of the park breeze was estimated at 39 Wm. This green space tempered the hot summer nights on a city block scale. These findings can help urban planners in designing a heat-adapted city. Copyright © by the American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, Inc.

Diurnal Cycle of Surface Flows During NAME and Comparison to Model Reanalysis

NASA Astrophysics Data System (ADS)

Ciesielski, P. E.; Johnson, R. H.

2007-05-01

During the North American Monsoon Experiment (NAME) an unprecedented surface data set of winds and thermodynamic variables was collected over the core monsoon region. The surface network included 63 automated sites with 1-30 min resolution data, 27 SMN operational sites (1-3 hourly data), and 56 US operational sites (1-3 hourly data) along the northern fringe of the monsoon region. These data, along with twice daily QuikSCAT oceanic surface winds, were quality controlled and objectively analyzed on to a uniform grid with quarter-degree, 1-h resolution for the period from 1 July - 15 August. An important application of the gridded winds is their use in diagnosing surface vertical motion due to slope flows over the Sierra Madre Occidental (SMO) terrain. With this dataset we examine the diurnal characteristics of surface fields as the monsoon evolves and compare these analyses to similar surface products from the special North American Regional Reanalysis (NARR) for NAME. Observed surface fields indicate that a robust land-sea breeze circulation is present over most of Gulf of California (GOC) region in response to the strong diurnal heating of land masses on both sides of the gulf. For reasons unclear at this time, many features of this land-sea breeze circulation are missing in the NARR. Evolution of the diurnal cycle of temperature and the land- sea breeze circulation as the monsoon progresses through the season shows a strong sensitivity to rainfall over the SMO and the coastal plains. Such a relationship likely reflects changes in land surface characteristics, such as evapotranspiration and albedo, as the forests of the SMO respond to monsoonal rains.

Following unblinding of the Diabetes Prevention Program (DPP) results, a 16-session lifestyle intervention program was offered to all study participants, including those who had initially been randomized to lifestyle treatment. This study compares the effects of the lifestyle program between participants who had previous exposure and those who had not. A 16-session behavioral intervention was conducted in groups at each of the 27 DPP sites during a transitional (bridge) period from the DPP trial to the DPP Outcomes Study (DPPOS). Session participation for this 6-month behavioral weight loss program was confirmed by originally randomized treatment groups. Independently assessed weight measurements were available within a 7-month period before and after the program for 2808 ethnically diverse participants. Participants from the lifestyle group in the DPP were the least likely to attend a repeat offering of a 16-session behavioral weight loss program conducted in groups. Weight loss during the transitional lifestyle program was strongly related to the duration of attendance in the three groups that were participating in the program for the first time (metformin, placebo and troglitazone), but not related to amount of earlier weight loss. Individuals who were naive to the behavioral program lost a greater amount of weight and this was strongly related to their degree of participation. A second exposure to a behavioral weight loss program resulted in unsatisfactory low attendance rates and weight loss.

Development and Evaluation of vetPAL, a Student-Led, Peer-Assisted Learning Program.

PubMed

Bates, Lucy S W; Warman, Sheena; Pither, Zoe; Baillie, Sarah

Based on an idea from a final-year student, Bristol Veterinary School introduced vetPAL, a student-led, peer-assisted learning program. The program involved fifth-year (final-year) students acting as tutors and leading sessions for fourth-year students (tutees) in clinical skills and revision (review) topics. The initiative aimed to supplement student learning while also providing tutors with opportunities to further develop a range of skills. All tutors received training and the program was evaluated using questionnaires collected from tutees and tutors after each session. Tutees' self-rated confidence increased significantly in clinical skills and for revision topics. Advantages of being taught by students rather than staff included the informal atmosphere, the tutees' willingness to ask questions, and the relatability of the tutors. The small group size and the style of learning in the revision sessions (i.e., group work, discussions, and interactivity) were additional positive aspects identified by both tutees and tutors. Benefits for tutors included developing their communication and teaching skills. The training sessions were considered key in helping tutors feel prepared to lead sessions, although the most difficult aspects were the lack of teaching experience and time management. Following the successful pilot of vetPAL, plans are in place to make the program permanent and sustainable, while incorporating necessary changes based on the evaluation and the student leader's experiences running the program. A vetPAL handbook has been created to facilitate organization of the program for future years.

Space transportation alternatives for large space programs: The International Space University Summer Session, 1992

NASA Technical Reports Server (NTRS)

Palaszewski, Bryan A.

1993-01-01

In 1992, the International Space University (ISU) held its Summer Session in Kitakyushu, Japan. This paper summarizes and expands upon some aspects of space solar power and space transportation that were considered during that session. The issues discussed in this paper are the result of a 10-week study by the Space Solar Power Program design project members and the Space Transportation Group to investigate new paradigms in space propulsion and how those paradigms might reduce the costs for large space programs. The program plan was to place a series of power satellites in Earth orbit. Several designs were studied where many kW, MW, or GW of power would be transmitted to Earth or to other spacecraft in orbit. During the summer session, a space solar power system was also detailed and analyzed. A high-cost space transportation program is potentially the most crippling barrier to such a space power program. At ISU, the focus of the study was to foster and develop some of the new paradigms that may eliminate the barriers to low cost for space exploration and exploitation. Many international and technical aspects of a large multinational program were studied. Environmental safety, space construction and maintenance, legal and policy issues of frequency allocation, technology transfer and control and many other areas were addressed. Over 120 students from 29 countries participated in this summer session. The results discussed in this paper, therefore, represent the efforts of many nations.

Observations of the trade wind wakes of Kauai and Oahu

NASA Astrophysics Data System (ADS)

Yang, Yang; Ma, Jian; Xie, Shang-Ping

2008-02-01

The Hawaiian islands of Kauai and Oahu stand in the path of the east-northeasterly trade winds, creating wakes in the lee. For the first time, the structure of the wakes and their diurnal cycle were observed on a cruise during 18-20 December 2006. The dynamic wakes, characterized by reduced trades, extend about 1 km in height with strong wind shear at the top. Thermal forcing of these small islands also affects the wake circulations. Sea breezes develop in the afternoon turning the winds into westerly near the shore in the wakes. At night, land breezes advect cool air from the islands, creating a shallow cool layer between the sea surface and a capping inversion. The warming in the wake in the afternoon extends much deeper (1.4 km) than the cool layer (0.5 km) at night. The effect of diurnal changes on cloud formation in the wakes is discussed, and the sharp variations in wind velocity lee of the islands may affect ocean currents, waves and mixing.

This study quantifies the processes that take place in the layer between the mean building height and the measurement level of an energy balance micrometeorological tower located in the dense old core of a coastal European city. The contributions of storage, vertical advection, horizontal advection and radiative divergence for heat are evaluated with the available measurements and with a three-dimensional, high-resolution meteorological simulation that had been evaluated against observations. The study focused on a summer period characterized by sea-breeze flows that affect the city. In this specific configuration, it appears that the horizontal advection is the dominant term. During the afternoon when the sea breeze is well established, correction of the sensible heat flux with horizontal heat advection increases the measured sensible heat flux up to 100 W m-2. For latent heat flux, the horizontal moisture advection converted to equivalent latent heat flux suggests a decrease of 50 W m-2. The simulation reproduces well the temporal evolution and magnitude of these terms.

Space launch, landing, and ground operations at the Kennedy Space Center (KSC) and Cape Canaveral Air Force Station (CCAFS) in east-central Florida are highly sensitive to mesoscale weather conditions throughout the year. Due to the complex land-water interfaces and the important role of mesoscale circulations, a high-resolution network of five 915-MHz Doppler Radar Wind Profilers (DRWP) and 44 wind towers was installed over the KSC/CCAFS area. By using quality-controlled 915-MHz DRAT data along with the near-surface tower observations, the Applied Meteorology Unit and KSC Weather Office have studied the development and evolution of various mesoscale phenomena across KSC/CCAFS such as sea and land breezes, low-level jets, and frontal passages. This paper will present some examples of mesoscale phenomena that can impact space operations at KSC/CCAFS, focusing on the utility of the 915-MHz DRWP network in identifying important characteristics of sea/land breezes and low-level jets.

Concentrations of radon 222Rn andair pollutants, meteorological parametersnear the surface and vertical profiles of meteorological elements were measured atUchio (Okayama City, Okayama Prefecture, Japan) 12 km north from the coast ofthe Inland Sea of Japan. In the nighttime, the 222Rn concentration increased in the case of weak winds, but did not increase as much in the case of moderate or strong winds, as had been expected. In the daytime, the 222Rn concentrationheld at a slightly higher than average level for the period from sunrise to about 1100 JST. It is considered that this phenomenon is due to a period of morning calm, that is, a transition period from land breeze to sea breeze.NO, which is sensitive to traffic volume,brought information concerning advection.Oxidant concentrations,which reflect the availability of sunlight,acted in the reverse manner to 222Rnconcentrations. Thus, a set of 222Rn and air pollutants could provide useful information regarding the local conditions of the atmospheric boundary layer.

Mind magic: a pilot study of preventive mind-body-based stress reduction in behaviorally inhibited and activated children.

Jellesma, Francine C; Cornelis, Janine

2012-03-01

The aim of this pilot study was to examine a mind-body-based preventive intervention program and to determine relationships between children's behavioral inhibition system (BIS) and behavioral activation system, stress, and stress reduction after the program. Children participated in the program (n=30) or in a control condition (n=24). They filled out questionnaires before and after the program and reported their levels of stress before and after each of the five sessions. The program consisted of weekly sessions. Each session incorporated yoga postures, visualization, and social exercises. Breathing techniques were integrated. Stress reductions were only seen in the intervention group and mainly in children with high BIS--irrespective of their behavioral activation system. The results demonstrate that children with high BIS may benefit from a mind-body-based stress reduction program.

2016-01-01

Cancer is a challenging experience and there is evidence that psychosocial interventions are effective at improving adjustment following treatment. At our cancer center, 14 cancer survivors (breast, prostate and blood cancers) completed a four-session cognitive-behavioral stress program. The first session was delivered at the survivor's local cancer center, where they were provided with a loaner tablet. The three subsequent sessions were delivered through group-based videoconference on the tablet. Session content was supplemented with a tailored ebook, designed specifically for this program. Participants provided feedback about the program as well as a standardized measure of perceived stress. Despite evidence that psychosocial programs are effective, there are significant barriers to dissemination, particularly for those residing in rural areas who do not live near academic medical centers where such programming is more readily available. Our experiences delivering a group-based videoconference program in cancer survivors are described, including positives and challenges associated with its design and implementation. Study participants enrolled from across four different US states, and the majority reported at least a 30-minute commute to their cancer center. This travel burden played a meaningful role in their desire to participate in our videoconference-based program. Although participants reported that session content was well suited to addressing stress management concerns, and session facilitators were able to effectively teach program techniques (eg progressive muscle relaxation, cognitive-reframing) and that the program was helpful overall, only modest improvements in perceived stress were seen. Participants noted challenges of the delivery including feeling disconnected from others, difficulty focusing, technical problems, and a desire for a longer program. Thus, although the novel delivery of a group-based, psychosocial program using tablet videoconference is feasible in a survivorship program, and desired by cancer survivors, key improvements must be made in future efforts. Our enthusiasm about the potential of telehealth must be tempered with the reality that such delivery can present challenges that interfere with the intervention implementation and efficacy. Facilitators must proactively address both the technological and interpersonal challenges associated with the use of group-based videoconference in order to improve its ability to positively impact cancer survivors. Many of these issues can be resolved prior to program launch, and require foresight and planning on the part of the program team.

Remote cochlear implant (CI) programming is a viable, safe, user-friendly and cost-effective procedure, equivalent to standard programming in terms of efficacy and user's perception, which can complement the standard procedures. The potential benefits of this technique are outlined. We assessed the technical viability, risks and difficulties of remote CI programming; and evaluated the benefits for the user comparing the standard on-site CI programming versus the remote CI programming. The Remote Programming System (RPS) basically consists of completing the habitual programming protocol in a regular CI centre, assisted by local staff, although guided by a remote expert, who programs the CI device using a remote programming station that takes control of the local station through the Internet. A randomized prospective study has been designed with the appropriate controls comparing RPS to the standard on-site CI programming. Study subjects were implanted adults with a HiRes 90K(R) CI with post-lingual onset of profound deafness and 4-12 weeks of device use. Subjects underwent two daily CI programming sessions either remote or standard, on 4 programming days separated by 3 month intervals. A total of 12 remote and 12 standard sessions were completed. To compare both CI programming modes we analysed: program parameters, subjects' auditory progress, subjects' perceptions of the CI programming sessions, and technical aspects, risks and difficulties of remote CI programming. Control of the local station from the remote station was carried out successfully and remote programming sessions were achieved completely and without incidents. Remote and standard program parameters were compared and no significant differences were found between the groups. The performance evaluated in subjects who had been using either standard or remote programs for 3 months showed no significant difference. Subjects were satisfied with both the remote and standard sessions. Safety was proven by checking emergency stops in different conditions. A very small delay was noticed that did not affect the ease of the fitting. The oral and video communication between the local and the remote equipment was established without difficulties and was of high quality.

To evaluate the efficacy of an oral hygiene program for orthodontic patients with cleft lip and palate. Retrospective pilot study. Hospital for Rehabilitation of Craniofacial Anomalies, Bauru, Brazil. One hundred twenty-two patients with complete cleft lip and palate undergoing orthodontic treatment. Orientation on toothbrushing and flossing, plaque disclosure, and scoring according to an especially designed index. Statistical comparison of variation in plaque index between sessions; correlation of intervals between sessions and variation in plaque index. Mean scores were reduced significantly, from 2.17 to 1.75 between first and second, 2.18 to 1.62 between first and third, and 1.93 to 1.62 between second and third sessions. Plaque reduction was inversely proportional to the time interval. The program demonstrated a significant plaque reduction. The highest reduction between the first and second sessions reveals the need to reinforce the initial instructions at all sessions. The greatest reduction observed at shorter intervals highlights the need for regular follow up. More controlled studies on larger samples should be encouraged to evaluate the validity of the index and the efficacy of similar programs worldwide.

European cooperation is a relevant subject that contributes to building a competitive network of high education institutions. A case of teacher mobility on behalf of the Erasmus programme is presented: it considers some Operations Research topics and the development of the Lego on My Decision module. The module considers eight lecture hours in four sessions: (i) the introductory session, to focus on the basics of computational linear algebra, linear programming, integer programming, with computational support (Excel®); (ii) the interim session, to address modelling subjects in a drop by-session; (iii) the advanced session, on the sequence of (i), to consider uncertainty and also how to use multi-criteria decision-making methods; (iv) the final session, to perform the evaluation of learning outcomes. This cooperation at European level is further exploited, including curricula normalisation and adjustments, cultural exchanges and research lines sharing in the idea of promoting the mobility of students and faculty.

A Simple Technique for Creating Regional Composites of Sea Surface Temperature from MODIS for Use in Operational Mesoscale NWP

NASA Technical Reports Server (NTRS)

Knievel, Jason C.; Rife, Daran L.; Grim, Joseph A.; Hahmann, Andrea N.; Hacker, Joshua P.; Ge, Ming; Fisher, Henry H.

2010-01-01

This paper describes a simple technique for creating regional, high-resolution, daytime and nighttime composites of sea surface temperature (SST) for use in operational numerical weather prediction (NWP). The composites are based on observations from NASA s Moderate Resolution Imaging Spectroradiometer (MODIS) aboard Aqua and Terra. The data used typically are available nearly in real time, are applicable anywhere on the globe, and are capable of roughly representing the diurnal cycle in SST. The composites resolution is much higher than that of many other standard SST products used for operational NWP, including the low- and high-resolution Real-Time Global (RTG) analyses. The difference in resolution is key because several studies have shown that highly resolved SSTs are important for driving the air sea interactions that shape patterns of static stability, vertical and horizontal wind shear, and divergence in the planetary boundary layer. The MODIS-based composites are compared to in situ observations from buoys and other platforms operated by the National Data Buoy Center (NDBC) off the coasts of New England, the mid-Atlantic, and Florida. Mean differences, mean absolute differences, and root-mean-square differences between the composites and the NDBC observations are all within tenths of a degree of those calculated between RTG analyses and the NDBC observations. This is true whether or not one accounts for the mean offset between the skin temperatures of the MODIS dataset and the bulk temperatures of the NDBC observations and RTG analyses. Near the coast, the MODIS-based composites tend to agree more with NDBC observations than do the RTG analyses. The opposite is true away from the coast. All of these differences in point-wise comparisons among the SST datasets are small compared to the 61.08C accuracy of the NDBC SST sensors. Because skin-temperature variations from land to water so strongly affect the development and life cycle of the sea breeze, this phenomenon was chosen for demonstrating the use of the MODIS-based composite in an NWP model. A simulated sea breeze in the vicinity of New York City and Long Island shows a small, net, but far from universal improvement when MODIS-based composites are used in place of RTG analyses. The timing of the sea breeze s arrival is more accurate at some stations, and the near-surface temperature, wind, and humidity within the breeze are more realistic.

Abstract Problem addressed Aspiring physician writers need an environment that promotes self-reflection and can help them improve their skills and confidence in writing. Objective of program To create a peer-support writing group for physicians in the Markham-Stouffville community in Ontario to promote professional development by encouraging self-reflection and fostering the concept of physician as writer. Program description The program, designed based on a literature review and a needs assessment, was conducted in 3 sessions over 6 months. Participants included an emergency physician, 4 family physicians, and 3 residents. Four to 8 participants per session shared their projects with guest physician authors. Eight pieces of written work were brought to the sessions, 3 of which were edited. A mixed quantitative and qualitative evaluation model was used with preprogram and postprogram questionnaires and a focus group. Conclusion This program promoted professional development by increasing participants’ frequency of self-reflection and improving their proficiency in writing. Successful elements of this program include creating a supportive group environment and having a physician-writer expert facilitate the peer-feedback sessions. Similar programs can be useful in postgraduate education or continuing professional development. PMID:27965348

Dissecting the role of sessional anatomy teachers: A systematic literature review.

Worldwide there is a growing reliance on sessional teachers in universities. This has impacted all disciplines in higher education including medical anatomy programs. The objective of this review was to define the role and support needs of sessional anatomy teachers by reporting on the (1) qualifications, (2) teaching role, (3) training, and (4) performance management of this group of educators. A systematic literature search was conducted on the 27 July 2017 in Scopus, Web of Science, and several databases on the Ovid, ProQuest and EBSCOhost platforms. The search retrieved 5,658 articles, with 39 deemed eligible for inclusion. The qualifications and educational distance between sessional anatomy teachers and their students varied widely. Reports of cross-level, near-peer and reciprocal-peer teaching were identified, with most institutes utilizing recent medical graduates or medical students as sessional teachers. Sessional anatomy teachers were engaged in the full spectrum of teaching-related duties from assisting students with cadaveric dissection, to marking student assessments and developing course materials. Fourteen institutes reported that training was provided to sessional anatomy teachers, but the specific content, objectives, methods and effectiveness of the training programs were rarely defined. Evaluations of sessional anatomy teacher performance primarily relied on subjective feedback measures such as student surveys (n = 18) or teacher self-assessment (n = 3). The results of this systematic review highlight the need for rigorous explorations of the use of sessional anatomy teachers in medical education, and the development of evidence-based policies and training programs that regulate and support the use of sessional teachers in higher education.

The Chronic Disease Self-Management Program (CDSMP) has been widely disseminated among various racial and ethnic populations. In addition to the six required CDSMP workshop sessions, the delivery sites have the option to offer a Session Zero (or zero class), an information session offered prior to Session One as a marketing tool. Despite assumptions that a zero class is helpful, little is known about the prevalence of these additional sessions or their impact on retaining participants in CDSMP workshops. This study aims to describe the proportion of CDSMP workshops that offered Session Zero and examine the association between Session Zero and workshop completion rates. Data were analyzed from 80,987 middle-aged and older adults collected during a two-year national dissemination of CDSMP. Generalized estimating equation regression analyses were conducted to assess the association between Session Zero and successful workshop completion (attending four or more of the six workshop sessions). On average, 21.04% of the participants attended workshops that offered Session Zero, and 75.33% successfully completed the CDSMP workshop. The participants of the workshops that offered Session Zero had significantly higher odds of completing CDSMP workshops than those who were not offered Session Zero (OR = 1.099, P = <0.001) after controlling for participants' demographic characteristics, race, ethnicity, living status, household income, number of chronic conditions, and workshop delivery type. As one of the first studies reporting the importance of an orientation session for participant retention in chronic disease management intervention projects, our findings suggest offering an orientation session may increase participant retention in similar translational efforts.

The aim of the study was to determine the acute systolic (SBP) and diastolic (DBP) blood pressure, rating of perceived exertion (RPE) and heart rate (HR) responses following two intense training sessions (24 hours apart). Nine male extreme conditioning program (ECP) practitioners with more than 6 months of experience (age 26.7 ± 6.6 years; body mass 78.8 ± 13.2 kg; body fat 13.5 ± 6.2 %) completed two experimental ECP sessions. Cardiovascular variables were measured before, immediately after and every 15 min during a 45 min recovery following each experimental session. Compared with pre-exercise data, our results showed a SBP decrease at 30 min post exercise session 1 (P≤0.05) and at 45 min following exercise session 2. DBP decreased (P≤0.05) at 15 min and 30 min following exercise session 1 and at 30 min after the exercise session 2, respectively. HR remained significantly higher (P≤0.05) 45 min following the first and second exercise session compared with pre-exercise values. Exercise session 1 induced a higher increase in HR (86 ± 11% of HRmax versus 82 ± 12% of HRmax, p = 0.01) and RPE (8.8 ± 1.2 versus 8.0 ± 1.2, p = 0.02) when compared to exercise session 2. In conclusion, post-exercise hypotension occurs following strenuous exercise sessions, regardless of the session design, which may have an important role in the prevention of cardiovascular diseases.

In this paper, the "Expérience sur Site pour COntraindre les Modèles de Pollution atmosphérique et de Transport d'Emissions" (ESCOMPTE) program is presented. The ESCOMPTE program is used to produce a relevant set of data for testing and evaluating regional pollution models. It includes high-resolution (in space and time) atmospheric emission inventories and field experiments, and covers an area of 120×120 km, centered over the Marseilles-Berre area in the southeast of France during Summer 2001. This region presents a high occurrence of photochemical pollution events, which result from numerous industrial and urban sources of primary pollutants. From the dynamical characteristics of the area, sea-breeze circulation and channeling effects due to terrain features highly influence the location of the pollutant plumes. ESCOMPTE will provide a highly documented framework for dynamics and chemistry studies. Campaign strategies and experimental set up are described. During the planning phase, existing modeling results helped defining the experimental design. The campaign involved surface measurement networks, remote sensing, ship-borne, balloon-borne, and airplane measurements. Mean standard meteorological parameters and turbulent fluxes, ozone, ozone precursors, photochemically active trace gases, and aerosols were measured. Five intensive observation periods (IOPs) were documented using a wide spectrum of instruments, involving aircraft (7) (one of them equipped with a Doppler lidar, the others for in situ meteorological and chemical measurements), constant volume balloons (33), ozone lidars (5), wind profilers (15 sodars and radars), Doppler scanning lidar (1), radiosonde systems (at 4 locations), instrumented ships (2). In addition to the air quality networks from environmental agencies, 15 supplementary ground stations equipped for chemistry and/or meteorology and/or surface flux measurements, were operational. All instruments were calibrated and compared during a Quality Control/Quality Assurance (QC/QA) week, at the very beginning of the campaign. Fifteen days were intensively documented during five IOPs, referenced as 1, 2a, 2b, 3, and 4. High pollution levels were encountered during sea-breeze conditions observed during IOPs 2b and 3, whereas IOPs 2a and 4 corresponded to moderate wind, and channeled plume regimes. In addition, hourly emissions inventories for all IOPs were established to complete data sets and to finalize the ESCOMPTE database (EDB). Two other projects were associated to ESCOMPTE: urban boundary layer (UBL) and tropospheric water vapor content by GPS tomography (GPS/H 2O). They took advantage of the scientific environment provided by ESCOMPTE.

We describe the key components of an outpatient pediatric recovery and rehabilitation program set up within the adult lung transplant service at the Alfred Hospital, Melbourne. Following discharge, pediatric lung transplant recipients and their families participated in an intensive 3-month outpatient rehabilitation program. Weekly sessions included education regarding transplant issues, physiotherapy, and occupational therapy sessions. The overall aim of the program was to comprehensively address physical rehabilitation and psychosocial and educational needs. Sessions tailored to meet the individual needs of the child were presented at an appropriate cognitive level. Education sessions for both the children and parents focused on medications, identification of infection and rejection, nutrition, physiotherapy/rehabilitation, occupational roles and stress management, donor issues, psychosocial readjustment, and transition issues. Physiotherapy included a progressive aerobic and strength training program, postural reeducation, and core stability. We incorporate Age-appropriate play activities: running, dancing, jumping, ball skills, and so on. Occupational therapy sessions addressed the primary roles of patient, students, and player. Transitions such as returning to school, friends, and the community were explored. Issues discussed included adjustment to new health status, strategies to manage side effects of medications, and altered body image issues. Weekly multidisciplinary team meetings were used to discuss and plan the rehabilitation progress. School liaison and visits occurred prior to school commencement with follow-up offered to review the ongoing transition process. Both patients and parents have reported a high level of satisfaction with the rehabilitation program. We plan to formally evaluate the program in the future.

2018-02-01

This study assessed the psychopathological effects of participation in a 10-session horticultural therapy program in patients with schizophrenia. The study design was pre and post test design of experimental and control groups. Twenty-eight Korean patients with schizophrenia, recruited from a mental health clinic and two mental health rehabilitation centers in Suwon, South Korea, were voluntarily assigned to either a control group (average age: 33.4±9.4years) or a horticultural therapy group (average age: 42.1±13.0years). The participants in the horticultural therapy group participated in a 10-session horticultural therapy program designed around various plant cultivating activities. The horticultural therapy program involved sessions once a week from April 2017 to June 2017. A psychiatrist evaluated the psychopathological symptoms of schizophrenic patients in both groups. To assess the clinical psychopathological effects, the Korean version of the Positive and Negative Syndrome Scale (PANSS) and Brief Psychiatric Rating Scale (BPRS) were used. The horticultural therapy group significantly improved in terms of positive, negative, and general symptoms on the PANSS after the 10-session horticultural therapy program. Moreover, the horticultural therapy group significantly improved in terms of clinical symptoms of schizophrenia in BPRS after the 10-session horticultural therapy program. However, there was no change in the PANSS and BPRS scores in the control group. This study showed the potential of horticultural therapy in improving psychopathological symptoms in psychiatric patients. Future studies should investigate the effects of long-term horticultural therapy program on the chronic symptoms of patients with schizophrenia. Copyright © 2017 Elsevier Ltd. All rights reserved.

2016-01-01

Background While Internet-based weight management programs can facilitate access to and engagement in evidence-based lifestyle weight loss programs, the results have generally not been as effective as in-person programs. Furthermore, motivational interviewing (MI) has shown promise as a technique for enhancing weight loss outcomes within face-to-face programs. Objective This paper describes the design, intervention development, and analysis of a therapist-delivered online MI intervention for weight loss in the context of an online weight loss program. Methods The MI intervention is delivered within the context of a randomized controlled trial examining the efficacy of an 18-month, group-based, online behavioral weight control program plus individually administered, synchronous online MI sessions relative to the group-based program alone. Six individual 30-minute MI sessions are conducted in private chat rooms over 18 months by doctoral-level psychologists. Sessions use a semistructured interview format for content and session flow and incorporate core MI components (eg, collaborative agenda setting, open-ended questions, reflective listening and summary statements, objective data, and a focus on evoking and amplifying change talk). Results The project was funded in 2010 and enrollment was completed in 2012. Data analysis is currently under way and the first results are expected in 2016. Conclusions This is the first trial to test the efficacy of a synchronous online, one-on-one MI intervention designed to augment an online group behavioral weight loss program. If the addition of MI sessions proves to be successful, this intervention could be disseminated to enhance other distance-based weight loss interventions.

PULSE@Parkes, Engaging Students through Hands-On Radio Astronomy

NASA Astrophysics Data System (ADS)

Hollow, Robert; Hobbs, George; Shannon, Ryan M.; Kerr, Matthew

2015-08-01

PULSE@Parkes is an innovative, free educational program run by CSIRO Astronomy and Space Science (CASS) in which high school students use the 64m Parkes radio telescope remotely in real time to observe pulsars then analyse their data. The program caters for a range of student ability and introduces students to hands-on observing and radio astronomy. Students are guided by professional astronomers, educators and PhD students during an observing session. They have ample time to interact with the scientists and discuss astronomy, careers and general scientific questions. Students use a web-based module to analyse pulsar properties. All data from the program are streamed via a web browser and are freely available from the online archive and may be used for open-ended student investigations. The data are also used by the team for ongoing pulsar studies with two scientific papers published to date.Over 100 sessions have been held so far. Most sessions are held at CASS headquarters in Sydney, Australia but other sessions are regularly held in other states with partner institutions. The flexibility of the program means that it is also possible to run sessions in other countries. This aspect of the program is useful for demonstrating capability, engaging students in diverse settings and fostering collaborations. The use of Twitter (@pulseatparkes) during allows followers worldwide to participate and ask questions.Two tours of Japan plus sessions in the UK, Netherlands and Canada have reached a wide audience. Plans for collaborations in China are well underway with the possibility of use with other countries also being explored. The program has also been successfully used in helping to train international graduate students via the International Pulsar Timing Array Schools. We have identified strong demand and need for programs such as this for training undergraduate students in Asia and the North America in observing and data analysis techniques so one area of planned development is teaching materials and a package for students at this level. The program has also been used to inform the development of educational programs for new telescopes such as the Australian SKA Pathfinder (ASKAP) and the SKA.http://pulseatparkes.atnf.csiro.au/

Detecting Aerosol Effect on Deep Precipitation Systems: A Modeling Study

NASA Astrophysics Data System (ADS)

Li, X.; Tao, W.; Khain, A.; Kummerow, C.; Simpson, J.

2006-05-01

Urban cities produce high concentrations of anthropogenic aerosols. These aerosols are generally hygroscopic and may serve as Cloud Condensation Nuclei (CCN). This study focuses on the aerosol indirect effect on the deep convective systems over the land. These deep convective systems contribute to the majority of the summer time rainfall and are important for local hydrological cycle and weather forecast. In a companion presentation (Tao et al.) in this session, the mechanisms of aerosol-cloud-precipitation interactions in deep convective systems are explored using cloud-resolving model simulations. Here these model results will be analyzed to provide guidance to the detection of the impact of aerosols as CCN on summer time, deep convections using the currently available observation methods. The two-dimensional Goddard Cumulus Ensemble (GCE) model with an explicit microphysical scheme has been used to simulate the aerosol effect on deep precipitation systems. This model simulates the size distributions of aerosol particles, as well as cloud, rain, ice crystals, snow, graupel, and hail explicitly. Two case studies are analyzed: a midlatitude summer time squall in Oklahoma, and a sea breeze convection in Florida. It is shown that increasing the CCN number concentration does not affect the rainfall structure and rain duration in these two cases. The total surface rainfall rate is reduced in the squall case, but remains essentially the same in the sea breeze case. For the long-lived squall system with a significant portion of the stratiform rain, the surface rainfall PDF (probability density function) distribution is more sensitive to the change of the initial CCN concentrations compared with the total surface rainfall. The possibility of detecting the aerosol indirect effect in deep precipitation systems from the space is also studied in this presentation. The hydrometeors fields from the GCE model simulations are used as inputs to a microwave radiative transfer model. It is found that Tb at higher frequencies (35 GHz and 85 GHz) are quite sensitive to the CCN concentration variations. This is because the higher frequency brightness temperatures are sensitive to large, ice-phase particles. In a clean environment, the deep convections produce larger cloud particles. When these cloud particles are transported above the freezing level by strong updrafts, they form larger precipitable ice particles (snow, graupel and hail) compared with dirty environment simulations. These larger ice particles result in significantly colder brightness temperatures at high frequencies in the clean scenario simulations.

2015-01-01

Background: The Chronic Disease Self-Management Program (CDSMP) has been widely disseminated among various racial and ethnic populations. In addition to the six required CDSMP workshop sessions, the delivery sites have the option to offer a Session Zero (or zero class), an information session offered prior to Session One as a marketing tool. Despite assumptions that a zero class is helpful, little is known about the prevalence of these additional sessions or their impact on retaining participants in CDSMP workshops. This study aims to describe the proportion of CDSMP workshops that offered Session Zero and examine the association between Session Zero and workshop completion rates. Methods: Data were analyzed from 80,987 middle-aged and older adults collected during a two-year national dissemination of CDSMP. Generalized estimating equation regression analyses were conducted to assess the association between Session Zero and successful workshop completion (attending four or more of the six workshop sessions). Results: On average, 21.04% of the participants attended workshops that offered Session Zero, and 75.33% successfully completed the CDSMP workshop. The participants of the workshops that offered Session Zero had significantly higher odds of completing CDSMP workshops than those who were not offered Session Zero (OR = 1.099, P = <0.001) after controlling for participants’ demographic characteristics, race, ethnicity, living status, household income, number of chronic conditions, and workshop delivery type. Conclusion: As one of the first studies reporting the importance of an orientation session for participant retention in chronic disease management intervention projects, our findings suggest offering an orientation session may increase participant retention in similar translational efforts.

Min, Alice A; Leetch, Aaron; Nuño, Tomas; Fiorello, Albert B

2016-01-01

Emergency medicine residency programs have evaluated the use of Multiple Mini Interviews (MMIs) for applicants. The authors developed an MMI-style method called the Fast Interview Track (FIT) to predict an applicant's 'fit' within an individual residency program. Applicants meet with up to five residents and are asked one question by each. Residents score the applicant using a Likert scale from 1 to 5 on two questions: 'How well does the applicant think on his/her feet?' and 'How well do you think the applicant will fit in here?'. To assess how well these questions predicted a resident's 'fit', current residents scored fellow residents on these same questions. These scores were compared with the residents' interview FIT scores. A postmatch survey of applicants who did not match at this program solicited applicants' attitudes toward the FIT sessions. Among the junior class, the correlation between interview and current scores was significant for question 1 (rho=0.5192 [p=0.03]) and question 2 (rho=0.5753 [p=0.01]). Among seniors, Spearman's rho was statistically significant for question 2, though not statistically significant for question 1. The chi-square measure of high scores (4-5) versus low scores (1-3) found a statistically significant association between interview and current scores for interns and juniors. Of the 29 responses to the postmatch survey, 16 (55%) felt FIT sessions provided a good sense of the program's personality and only 6 (21%) disagreed. Nine (31%) felt FIT sessions positively impacted our program's ranking and 11 (38%) were 'Neutral'. Only two (7%) reported that FIT sessions negatively impacted their ranking of our program. FIT provided program leadership with a sense of an applicant's 'fit' within this program. Interview day scores correlated with scores received during residency. Most applicants report a positive experience with FIT sessions. FIT provides a useful tool to recruit applicants who fit with the residency program.

Criando a Nuestros Niños hacia el Éxito (CANNE) is the Spanish adaptation of Parenting Our Children to Excellence (PACE). A pilot study conducted with 124 parents of preschoolers (mostly recent Mexican immigrants) provides preliminary evidence for the community acceptability and efficacy of CANNE. Eighty-eight of the 124 parents who enrolled in the program attended one or more of the 8 sessions (17% attended 1 session, 11% attended 2-4 sessions, and 72% attended 5 or more sessions), participated actively in sessions, and expressed high degrees of program satisfaction. Over time, parents improved on measures of harsh-inconsistent discipline, and children improved on social competence and social-communication skills. When high-versus-low attenders were compared, high attenders (parents who attended 4 sessions or more) reported greater increases than low attenders in their appropriate-positive parenting practices and clear expectations, and in their children's social competence and communication skills, and they reported greater decreases in their harsh-inconsistent discipline and in their children's aggressiveness and hyperactivity. Some of these changes were evident by the end of the program, whereas others became apparent (or stronger) over a 3-month follow-up period. These encouraging results point to the need for an efficacy study that assesses how well CANNE can help larger numbers of Latino parents in the important task of bringing up their young children in the United States.

Role of meteorological processes in two New England ozone episodes during summer 2001

NASA Astrophysics Data System (ADS)

Mao, Huiting; Talbot, Robert

2004-10-01

We examined the impact of dynamical processes on spatial variability in ozone (O3) mixing ratios at closely spaced air monitoring sites in southern New Hampshire (NH) during two O3 episodes, July 21-25 and August 2, 2001. The Meso-scale Meteorological Model (MM5) and the Community Multiscale Air Quality (CMAQ) photochemical model were applied together with ground-based atmospheric chemistry observations conducted by the Atmospheric Investigation, Regional Modeling, Analysis and Prediction (AIRMAP) program at the University of New Hampshire. Observations and model simulations suggested that during the July episode long-range transport via the nocturnal low-level jet (LLJ) played an important role in producing elevated daytime mixing ratios of O3. The marine site Isle of Shoals experienced the highest level of O3, possibly a result of having more diverse upwind sources and less ventilation compared to continental sites. Our model results suggest that during daytime the shallow sea breeze circulation contributes to high levels of O3 at coastal and marine sites while the channeling effect of the Appalachian Mountains influences inland locations. In contrast to the July event, the event on August 2 was characterized by weak and transient synoptic flows, indicating insufficient time for transport of O3 and its precursors from distant sources to inland sites in NH. Backward trajectories for both events showed that O3-rich air masses from the Boston metropolitan area can contribute to the high levels of O3 (>120 ppbv) at coastal and marine sites in southern NH. Our results suggest that the International Consortium of Atmospheric Research on Transport and Transformation (ICARTT), an international field campaign based in the northeastern United States in summer 2004, should coordinate mobile platforms to investigate the vertical structure and chemical composition of the LLJ, the sea breeze, and the terrain-forced flows, and estimate the influx of O3 and its precursors to central New England.

This study presents a new method that incorporates modern air dispersion models allowing local terrain and land-sea breeze effects to be considered along with political and natural boundaries for more accurate mapping of air quality zones (AQZs) for coastal urban centers. This method uses local coastal wind patterns and key urban air pollution sources in each zone to more accurately calculate air pollutant concentration statistics. The new approach distributes virtual air pollution sources within each small grid cell of an area of interest and analyzes a puff dispersion model for a full year's worth of 1-hr prognostic weather data. The difference of wind patterns in coastal and inland areas creates significantly different skewness (S) and kurtosis (K) statistics for the annually averaged pollutant concentrations at ground level receptor points for each grid cell. Plotting the S-K data highlights grouping of sources predominantly impacted by coastal winds versus inland winds. The application of the new method is demonstrated through a case study for the nation of Kuwait by developing new AQZs to support local air management programs. The zone boundaries established by the S-K method were validated by comparing MM5 and WRF prognostic meteorological weather data used in the air dispersion modeling, a support vector machine classifier was trained to compare results with the graphical classification method, and final zones were compared with data collected from Earth observation satellites to confirm locations of high-exposure-risk areas. The resulting AQZs are more accurate and support efficient management strategies for air quality compliance targets effected by local coastal microclimates. A novel method to determine air quality zones in coastal urban areas is introduced using skewness (S) and kurtosis (K) statistics calculated from grid concentrations results of air dispersion models. The method identifies land-sea breeze effects that can be used to manage local air quality in areas of similar microclimates.

The objective of our study was to evaluate the exercise and educational intervention in the city of Lubbock via GET FiT Lubbock (GFL) program. The GFL program was designed to increase exercise and educational opportunities, which positively impact health risk factors in Lubbock residents. The GFL program design included the recruitment of subjects to participate on a team that consisted of four individuals, each subject tracked their exercise minutes, and their educational session attendance. The tracking of exercise and educational sessions was done on the GFL website. Biometric testing was conducted pre- and post- intervention. The program was located within the Lubbock community in places that were close to their place of residence. The intervention included walking and educational sessions, including goal setting lectures, nutrition information, and exercise demonstrations. Study participants, included male and female adults who tracked their exercise time and educational sessions. Exercise minutes and educational session attendance were self-reported. Our data analysis revealed that significant difference was found between pre- and post- intervention measures, including weight, body mass index (BMI), high-density lipoprotein (HDL). Significant difference was found for weight, BMI, and HDL in females. Based on these findings, we conclude that the intervention showed positive effects on exercise and lifestyle.

In this study, we examined the regularly scheduled, formal teaching sessions in a single anesthesiology residency program to (1) map the most common primary instructional methods, (2) map the use of 10 known teaching techniques, and (3) assess if residents scored sessions that incorporated active learning as higher quality than sessions with little or no verbal interaction between teacher and learner. A modified Delphi process was used to identify useful teaching techniques. A representative sample of each of the formal teaching session types was mapped, and residents anonymously completed a 5-question written survey rating the session. The most common primary instructional methods were computer slides-based classroom lectures (66%), workshops (15%), simulations (5%), and journal club (5%). The number of teaching techniques used per formal teaching session averaged 5.31 (SD, 1.92; median, 5; range, 0-9). Clinical applicability (85%) and attention grabbers (85%) were the 2 most common teaching techniques. Thirty-eight percent of the sessions defined learning objectives, and one-third of sessions engaged in active learning. The overall survey response rate equaled 42%, and passive sessions had a mean score of 8.44 (range, 5-10; median, 9; SD, 1.2) compared with a mean score of 8.63 (range, 5-10; median, 9; SD, 1.1) for active sessions (P = 0.63). Slides-based classroom lectures were the most common instructional method, and faculty used an average of 5 known teaching techniques per formal teaching session. The overall education scores of the sessions as rated by the residents were high.

The long-term objective of this project is to make health sciences librarians more effective in their role by using emerging technologies to deliver timely continuing education (CE) programs to them regardless of their physical location. The goals of the one-year planning project at the William H. Welch Medical Library are to plan, implement, and evaluate a pilot CE program that includes (1) a three-day general-interest session organized in four tracks: Market Forces and Management, Information Technology and the Internet, Publishing and Copyright, and Education; (2) a one-day special topic session on the Informatics of the Human Genome Project; and (3) an electronic poster session in parallel with the general-interest session. The program will be offered in three simultaneous formats: (1) on-site, in a distance-learning classroom in Baltimore; (2) as a telecourse, in a similar classroom outside Washington, DC; and (3) online, via the World Wide Web. An electronic proceedings of the entire program will be published on the Web to serve as a continuously available CE resource for health sciences librarians. This paper gives an overview of the planning process, presents a status report on the programmatic and technical implementation of the pilot project at its midpoint, and discusses future directions for the program.

We present our experience of training residents in a weekend robotic training program to assess its effectiveness and perceived usefulness. Bimonthly training sessions were arranged such that residents could sign up for hour-long, weekend training sessions. They are required to complete four training sessions. Five tasks were scored for time and accuracy: Peg-Board, checkerboard, string running, pattern cutting, and suturing. Participants completed surveys (5-point Likert scale) regarding program utility, ease of attendance, and interest in future weekend training sessions. Mean number of trials completed by 19 residents was >4, and 16 completed the trials within an average of 13.7±8.1 mos. Significant improvements (P<0.05) were seen in final trials for Peg-Board accuracy (95.8% vs 79.0%), checkerboard deviation (4.8% vs 18.2%), and time (293 s vs 404 s), pattern-cutting time (257 s vs 399 s), and suture time (203 s vs 305 s). Time to previous session correlated with relative improvement in Peg-Board and pattern-cutting time (r=0.300 and 0.277, P=0.021 and 0.041), but no specific training interval was predictive of improvement. Residents found the course easy to attend (3.6), noted skills improvement (4.1), and found it useful (4.0). Training in the weekend sessions improved performance of basic tasks on the robot. Training interval had a modest effect on some exercises and may be more important for difficult tasks. This training program is a useful supplement to resident training and would be easy to implement in most programs.

Telerehabilitation booster sessions and remote patient monitoring in the management of chronic low back pain: A case series.

PubMed

Peterson, Seth

2018-05-01

Improvements in chronic low back pain (CLBP) seen in physical therapy do not appear to be retained over the long term. Booster sessions have been proposed, but barriers exist to their implementation. Telerehabilitation (TR) and remote patient monitoring (RPM) may be ways to circumvent these barriers. The purpose of this case series was to describe the implementation of TR booster sessions and RPM in three patients with CLBP. Three females with CLBP tracked their daily pain level and home exercise program adherence using a mobile phone application for 12 months following discharge from traditional face-to-face physical therapy. Synchronous audio and video TR booster sessions were conducted at months 1, 3, 6, and 12. All patients met their individual goals. They demonstrated excellent home exercise program adherence and self-efficacy. A temporary increase in pain was seen in all patients, but they managed solely with the TR booster sessions and without other healthcare resources. Satisfaction with the program was very high. This case series describes the use of TR booster sessions and RPM in three patients with CLBP. The positive results suggest this approach may be helpful in improving long-term management of patients with CLBP but demand further investigation.

The educational literature generally suggests that supplemental instruction (SI) is effective in improving academic performance in traditionally difficult courses. A pilot program of peer teaching based on the SI model was implemented for an undergraduate course in human anatomy. Students in the course were stratified into three groups based on the number of peer teaching sessions they attended: nonattendees (0 sessions), infrequently attended (1-3 sessions), and frequently attended (≥ 4 sessions). After controlling for academic preparedness [i.e., admission grade point average (AGPA)] using an analysis of covariance, the final grades of frequent attendees were significantly higher than those of nonattendees (P = 0.025) and infrequent attendees (P = 0.015). A multiple regression analysis was performed to estimate the relative independent contribution of several variables in predicting the final grade. The results suggest that frequent attendance (β = 0.245, P = 0.007) and AGPA (β = 0.555, P < 0.001) were significant positive predictors, while being a first-year student (β = -0.217, P = 0.006) was a significant negative predictor. Collectively, these results suggest that attending a certain number of sessions may be required to gain a noticeable benefit from the program, and that first-year students (particularly those with a lower level of academic preparedness) would likely stand to benefit from maximally using the program. End-of-semester surveys and reports indicate that the program had several additional benefits, both to the students taking the course and to the students who served as program leaders.

The aim of this study is to evaluate the effectiveness of a disaster preparedness training program in a Paediatric Emergency Department (PED). A quasi-experimental study was conducted using an anonymous questionnaire that was distributed to health care providers of a PED in a tertiary paediatric hospital. The questions concerned the disaster plan (DP), including theoretical and practical aspects. Questionnaires were distributed and completed in January 2014 (period 1) and November 2014 (period 2). The disaster training program includes theoretical and practical sessions. A total of 110 questionnaires were collected in period 1, and 80 in period 2. Almost three-quarters (71.3%) of PED staff attended the theoretical sessions, and 43.8% attended the practical sessions. The application of this training program significantly improved knowledge about the DP, but no improvement was observed in the practical questions. PED staff felt more prepared to face a disaster after the training program (15.5% vs. 41.8%, P<.001). The training program improved some knowledge about the disaster plan, but it has not improved responses in practical situations, which may be due to the low attendance at practical sessions and the time between the training program and the questionnaires.

The present study investigated the impact of a Science, Technology, Engineering, Mathematics and Health (STEM+H) university-based pipeline program, the Careers in Health and Medical Professions Program, over the course of two summers among predominantly African-American high school students recruited from urban school districts ( N = 155). Based on a mixed methods approach, results indicated that youth made significant gains in both academic and career knowledge. Furthermore, youth generally rated the program's sessions favorably, but also rated sessions with varying levels of satisfaction. The limitations and implications for program delivery and evaluation methods among pipeline programs are discussed.

2011-09-01

Evidence for effectiveness of pediatric physical therapy in infants at high risk for developmental motor disorders is limited. Therefore, "Coping With and Caring for Infants With Special Needs" (COPCA), a family-centered, early intervention program, was developed. The COPCA program is based on 2 components: (1) family involvement and educational parenting and (2) the neuromotor principles of the neuronal group selection theory. The COPCA coach uses principles of coaching to encourage the family's own capacities for solving problems of daily care and incorporating variation, along with trial and error in daily activities. The purpose of this study was to evaluate whether the content of sessions of the home-based, early intervention COPCA program differs from that of traditional infant physical therapy (TIP) sessions, which in the Netherlands are largely based on neurodevelopmental treatment. The study was conducted at the University Medical Center Groningen in the Netherlands. A quantitative video analysis of therapy sessions was conducted with infants participating in a 2-arm randomized trial. Forty-six infants at high risk for developmental motor disorders were randomly assigned to receive COPCA (n=21) or TIP (n=25) between 3 and 6 months corrected age. Intervention sessions were videotaped at 4 and 6 months corrected age and analyzed with a standardized observation protocol for the classification of physical therapy actions. Outcome parameters were relative amounts of time spent on specific physical therapy actions. The content of COPCA and TIP differed substantially. For instance, in TIP sessions, more time was spent on facilitation techniques, including handling, than in COPCA sessions (29% versus 3%, respectively). During COPCA, more time was spent on family coaching and education than during TIP (16% versus 4%, respectively). The major limitation of the study was its restriction to the Netherlands, implying that findings cannot be generalized automatically to other countries. The COPCA program differs broadly from TIP as applied in the Netherlands. Studies on the effectiveness of this family-centered program are needed.

To present a multiple-instructor, active-learning strategy in the undergraduate medical curriculum. This educational research is a descriptive one. Shared teaching sessions, were designed for undergraduate medical students in six organ-system based courses. Sessions that involved in-class discussions of integrated clinical cases were designed implemented and moderated by at least 3 faculties (clinicians and basic scientists). The participants in this study include the basic sciences medical students of The Tehran University of Medical Sciences. Students' reactions were assessed using an immediate post-session evaluation form on a 5-point Likert scale. Six two-hour sessions for 2 cohorts of students, 2013 and 2014 medical students during their two first years of study were implemented from April 2014 to March 2015. 17 faculty members participated in the program, 21 cases were designed, and participation average was 60 % at 6 sessions. Students were highly appreciative of this strategy. The majority of students in each course strongly agreed that this learning practice positively contributed to their learning (78%) and provided better understanding and application of the material learned in an integrated classroom course (74%). They believed that the sessions affected their view about medicine (73%), and should be continued in future courses (80%). The percentage demonstrates the average of all courses. The program helped the students learn how to apply basic sciences concepts to clinical medicine. Evaluation of the program indicated that students found the sessions beneficial to their learning.

To describe institutional variation in traumatic brain injury (TBI) inpatient rehabilitation program characteristics and evaluate to what extent patient factors and center effects explain how TBI inpatient rehabilitation services are delivered. Secondary analysis of a prospective, multicenter, cohort database. TBI inpatient rehabilitation programs. Patients with complicated mild, moderate, or severe TBI (N=2130). Not applicable. Mean minutes; number of treatment activities; use of groups in occupational therapy, physical therapy, speech therapy, therapeutic recreation, and psychology inpatient rehabilitation sessions; and weekly hours of treatment. A wide variation was observed between the 10 TBI programs, including census size, referral flow, payer mix, number of dedicated beds, clinician experience, and patient characteristics. At the centers with the longest weekday therapy sessions, the average session durations were 41.5 to 52.2 minutes. At centers with the shortest weekday sessions, the average session durations were approximately 30 minutes. The centers with the highest mean total weekday hours of occupational, physical, and speech therapies delivered twice as much therapy as the lowest center. Ordinary least-squares regression modeling found that center effects explained substantially more variance than patient factors for duration of therapy sessions, number of activities administered per session, use of group therapy, and amount of psychological services provided. This study provides preliminary evidence that there is significant institutional variation in rehabilitation practice and that center effects play a stronger role than patient factors in determining how TBI inpatient rehabilitation is delivered.

In the initial study, 48 subjects of the total (N = 63) ultimately used, were assigned to one of three treatments: four hypnotic sessions with a booster, two hypnotic sessions, or two hypnotic and two behavioral sessions with a booster. A follow-up group was later recruited composed of 15 subjects who received four hypnotic sessions and a booster session with less time between sessions. The results indicated no difference in smoking cessation 6 months after treatment regardless of the frequency, length between sessions, or addition of behavioral methods. Successful subjects were more educated, less able to utilize their imagination, and had fewer smokers at home.

Observed and simulated sea breeze characteristics over Rayong coastal area, Thailand

Phan, Tung Thanh; Manomaiphiboon, Kasemsan

2012-05-01

This work presents the detailed characterization of sea breeze (SB) over the Rayong coastal area, one of the most rapidly developed and highly industrialized areas during the last decade in Thailand, using observation data analysis and fine-resolution (2 km) mesoscale meteorological modeling with incorporation of new land cover and satellite-derived vegetation fraction data sets. The key characteristics considered include frequency of SB occurrence, sea-breeze day (SBD) identification, degree of inland penetration, and boundary layer development. It was found that SBs occur frequently in the winter due mainly to relatively large land-sea temperature contrasts and minimally in the wet season. Monthly mean SB onset and cessation times are at around 12-15 local time (LT) and 18-21 LT, respectively, and its strength peaks during the early- to mid-afternoon. Monthly SB hodographs generally exhibit clockwise rotations, and SB inland penetration (at PCD-T tower) ranges widely with the monthly means of 25-55 km from the coast. Mesoscale MM5 modeling was performed on two selected SBDs (13 January and 16 March 2006), on which the SBs are under weak and onshore strong influences from background winds, respectively. Simulated near-surface winds and temperature were found to be in fair-to-acceptable agreement with the observations. The SB circulation along the Rayong coast is clearly defined with a return flow aloft and a front on 13 January, while it is enhanced by the onshore background winds on 16 March. Another SB along the Chonburi coast also develops separately, but their fronts merge into one in the mid-afternoon, resulting in large area coverage by the SB. Simulated planetary boundary layer height over the land area is significantly affected by a thermal internal boundary layer (TIBL) induced by an SB, which is found to be low near the coast and increases toward the front (up to 800-1,000 m along the Rayong coast).

Meteorological impact assessment of possible large scale irrigation in Southwest Saudi Arabia

On continental to regional scales feedbacks between landuse and landcover change and climate have been widely documented over the past 10-15 years. In the present study we explore the possibility that also vegetation changes over much smaller areas may affect local precipitation regimes. Large scale (˜ 10 5 ha) irrigated plantations in semi-arid environments under particular conditions may affect local circulations and induce additional rainfall. Capturing this rainfall 'surplus' could then reduce the need for external irrigation sources and eventually lead to self-sustained water cycling. This concept is studied in the coastal plains in South West Saudi Arabia where the mountains of the Asir region exhibit the highest rainfall of the peninsula due to orographic lifting and condensation of moisture imported with the Indian Ocean monsoon and with disturbances from the Mediterranean Sea. We use a regional atmospheric modeling system (RAMS) forced by ECMWF analysis data to resolve the effect of complex surface conditions in high resolution (Δ x = 4 km). After validation, these simulations are analysed with a focus on the role of local processes (sea breezes, orographic lifting and the formation of fog in the coastal mountains) in generating rainfall, and on how these will be affected by large scale irrigated plantations in the coastal desert. The validation showed that the model simulates the regional and local weather reasonably well. The simulations exhibit a slightly larger diurnal temperature range than those captured by the observations, but seem to capture daily sea-breeze phenomena well. Monthly rainfall is well reproduced at coarse resolutions, but appears more localized at high resolutions. The hypothetical irrigated plantation (3.25 10 5 ha) has significant effects on atmospheric moisture, but due to weakened sea breezes this leads to limited increases of rainfall. In terms of recycling of irrigation gifts the rainfall enhancement in this particular setting is rather insignificant.

The influence of training characteristics on the effect of aerobic exercise training in patients with chronic heart failure: A meta-regression analysis.

Although aerobic exercise training has shown to be an effective treatment for chronic heart failure patients, there has been a debate about the design of training programs and which training characteristics are the strongest determinants of improvement in exercise capacity. Therefore, we performed a meta-regression analysis to determine a ranking of the individual effect of the training characteristics on the improvement in exercise capacity of an aerobic exercise training program in chronic heart failure patients. We focused on four training characteristics; session frequency, session duration, training intensity and program length, and their product; total energy expenditure. A systematic literature search was performed for randomized controlled trials comparing continuous aerobic exercise training with usual care. Seventeen unique articles were included in our analysis. Total energy expenditure appeared the only training characteristic with a significant effect on improvement in exercise capacity. However, the results were strongly dominated by one trial (HF-action trial), accounting for 90% of the total patient population and showing controversial results compared to other studies. A repeated analysis excluding the HF-action trial confirmed that the increase in exercise capacity is primarily determined by total energy expenditure, followed by session frequency, session duration and session intensity. These results suggest that the design of a training program requires high total energy expenditure as a main goal. Increases in training frequency and session duration appear to yield the largest improvement in exercise capacity. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

An educational program to improve the management of HIV patients was introduced in the department of infectious diseases of Ibn Rochd hospital, Casablanca, Morocco in January 2000. The project, funded by the GlaxoSmithKline Foundation, began by training ward physicians as well as volunteers from the ALLOCS (Association de lutte contre le sida) in pedagogy and patient education techniques (four-day course). Other sessions reviewed HIV management and treatment. Treatment training sessions were offered to all patients receiving antiretroviral treatment when the program began. All had been taking medication for at least two months and gave their informed consent to participation in the project. Each patient's sessions took place just after his or her medical consultation, in a room set aside for this purpose in the hospital. During the first session the educator established an educational diagnosis and defined educational objectives according to the individual patient's needs. Objectives were related to patients' knowledge about HIV transmission prevention and treatment management (including problem-solving for mild adverse events, delays, forgetting, vacations etc.). Trainers used several educational tools, including therapeutic planning (planning card with self-adhesive stickers showing the treatment medication); a folder of drawings depicting HIV transmission, prevention, and natural history, as well as the aims of antiretroviral therapy; decks of cards illustrating symptoms and psycho-sociological problems. Each patient had to attend at least 3 educational sessions. The program was evaluated at the end of one year. Patients' attendance, treatment adherence, laboratory test results (CD4 count, viral load), satisfaction about patient-staff relationships and knowledge about HIV disease and treatment were assessed on an on-going basis with various questionnaires and data collection systems. In all, 96 patients attended classes, with a mean of 14 sessions per patient per year. After 6 and 12 months of training, patients' CD4 cell counts increased, and the proportion with viral loads below the detection level rose, as did adherence scores. Patients' knowledge appeared to have improved at 6 months but regressed somewhat at 12 months. This may be explained by program timing: most educational sessions take place during the first 6 months of patient enrolment in the program. Patient satisfaction about the program and their care reveals that they acquired autonomy in managing their disease and treatment. Their satisfaction at 12 months, however, was lower than it was at 6 months. One explanation may be that more educated patients are more demanding, but another is the staff turnover in the program. New staff may have required more support and training than was then available. This pilot program allowed us to draft guidelines for setting up educational programs for HIV patients in relatively poor countries.

PEACH™QLD translated the PEACH™ Program, designed to manage overweight/obesity in primary school-aged children, from efficacious RCT and small scale community trial to a larger state-wide program. This paper describes the lessons learnt when upscaling to universal health coverage. The 6-month, family-focussed program was delivered in Queensland, Australia from 2013 to 2016. Its implementation was planned by researchers who developed the program and conducted the RCT, and experienced project managers and practitioners across the health continuum. The intervention targeted parents as the agents of change and was delivered via parent-only group sessions. Concurrently, children attended fun, non-competitive activity sessions. Sessions were delivered by facilitators who received standardised training and were employed by a range of service providers. Participants were referred by health professionals or self-referred in response to extensive promotion and marketing. A pilot phase and a quality improvement framework were planned to respond to emerging challenges. Implementation challenges included engagement of the health system; participant recruitment; and engagement. A total of 1513 children (1216 families) enrolled, with 1122 children (919 families) in the face-to-face program (105 groups in 50 unique venues) and 391 children (297 families) in PEACH™ Online. Self-referral generated 68% of enrolments. Unexpected, concurrent and, far-reaching public health system changes contributed to poor program uptake by the sector (only 56 [53%] groups delivered by publicly-funded health organisations) requiring substantial modification of the original implementation plan. Process evaluation during the pilot phase and an ongoing quality improvement framework informed program adaptations that included changing from fortnightly to weekly sessions aligned with school terms, revision of parent materials, modification of eligibility criteria to include healthy weight children and provision of services privately. Comparisons between pilot versus state-wide waves showed comparable prevalence of families not attending any sessions (25% vs 28%) but improved number of sessions attended (median = 5 vs 7) and completion rates (43% vs 56%). Translating programs developed in the research context to enable implementation at scale is complex and presents substantial challenges. Planning must ensure there is flexibility to accommodate and proactively manage the system changes that are inevitable over time. ACTRN12617000315314 .

We describe the translation of K. R. Lorig and colleagues' Chronic Disease Self-Management Program (CDSMP) for delivery in a senior center and evaluate pre-post benefits for African American participants. Modifications to the CDSMP included a name change; an additional introductory session; and course augmentations involving culturally relevant foods, stress reduction techniques, and communicating with racially/ethnically diverse physicians. We recruited participants from senior center members, area churches, and word of mouth. We conducted baseline and 4-month post-interviews. A total of 569 African American elders attended an introductory session, with 519 (91%) enrolling in the 6-session program. Of the 519, 444 (86%) completed >/=4 sessions and 414 (79%) completed pre-post interviews. We found small but statistically significant improvements for exercise (p =.001), use of cognitive management strategies (p =.001), energy/fatigue (p =.001), self-efficacy (p =.001), health distress (p =.001), and illness intrusiveness in different life domains (probabilities from.001-.021). We found no changes for health utilization. Outcomes did not differ by gender, number of sessions attended, number and type of chronic conditions, facilitator, leader, or recruitment site. The CDSMP can be translated for delivery by trained senior center personnel to African American elders. Participant benefits compare favorably to original trial outcomes. The translated program is replicable and may help to address health disparities.

It is well established that exercise is beneficial for prostate cancer survivors. The challenge for health professionals is to create effective strategies to encourage survivors to exercise in the community. Many community exercise programs are brief in duration (e.g. <5 exercise sessions); whilst evidence for the efficacy of exercise within the literature are derived from exercise programs ≥8 weeks in duration, it is unknown if health benefits can be obtained from a shorter program. This study examined the effect of a four-session individualized and supervised exercise program on the physical and psychosocial health of prostate cancer survivors. Fifty-one prostate cancer survivors (mean age 69±7 years) were prescribed 1 h, individualized, supervised exercise sessions once weekly for 4 weeks. Participants were encouraged to increase their physical activity levels outside of the exercise sessions. Objective measures of muscular strength, exercise capacity, physical function and flexibility; and self-reported general, disease-specific and psychosocial health were assessed at baseline and following the intervention. Improvements were observed in muscle strength (leg press 17.6 percent; P < 0.001), exercise capacity (400-m walk 9.3 percent; P < 0.001), physical function (repeated chair stands 20.1 percent, usual gait speed 19.3 percent, timed up-and-go 15.0 percent; P < 0.001), flexibility (chair sit and reach +2.9 cm; P < 0.001) and positive well-being (P = 0.014) following the exercise program. A four-session exercise program significantly improved the muscular strength, exercise capacity, physical function and positive well-being of prostate cancer survivors. This short-duration exercise program is safe and feasible for prostate cancer survivors and a randomized controlled trial is now required to determine whether a similar individualized exercise regimen improves physical health and mental well-being over the short, medium and long term. © 2016 John Wiley & Sons Australia, Ltd.

There is a dearth of literature to guide the development of community-based HIV and sexually transmitted infection (STI) prevention and sexual health promotion programs within Inuit communities. The aim of this study was to create a dialogue with Inuit women to address the lack of information available to inform programming to improve the sexual health of Inuit women, their families, and their communities in the Canadian Arctic. This study used Indigenous methodologies and methods by drawing from Inuit Qaujimajatuqangit and postcolonial research theory in a framework of Two-Eyed Seeing, and using storytelling sessions to gather data. Community-based participatory research principles informed the design of the study, ensuring participants were involved in all stages of the project. Nine storytelling sessions took place with 21 Inuit women aged 18-61 years. Storytelling sessions were audio recorded and transcribed verbatim, and Atlas.ti aided in the organization of the data for collaborative thematic analysis within three participatory analysis sessions with 13 of the participating women. From the storytelling and analysis sessions, five major themes emerged: (a) the way it used to be, (b) change, (c) family, (d) intimate relationships and (e) holistic strategies. Participating women emphasized that HIV and STI prevention and sexual health promotion programming needs to take a holistic, community-wide, family-focused and youth-centred approach within their communities. Participants identified several important determinants of sexual health and shared ideas for innovative approaches they believe will work as prevention efforts within their communities. This article specifically focuses on key characteristics of programming aimed at STI and HIV prevention and sexual health promotion that were identified throughout participants' stories. This study has provided a narrative to complement the epidemiological data that highlight the urgent need for prevention programming.

The educational literature generally suggests that supplemental instruction (SI) is effective in improving academic performance in traditionally difficult courses. A pilot program of peer teaching based on the SI model was implemented for an undergraduate course in human anatomy. Students in the course were stratified into three groups based on the number of peer teaching sessions they attended: nonattendees (0 sessions), infrequently attended (1‐3 sessions), and frequently attended (≥ 4 sessions). After controlling for academic preparedness [i.e., admission grade point average (AGPA)] using an analysis of covariance, the final grades of frequent attendees were significantly higher than those of nonattendees (P = 0.025) and infrequent attendees (P = 0.015). A multiple regression analysis was performed to estimate the relative independent contribution of several variables in predicting the final grade. The results suggest that frequent attendance (β = 0.245, P = 0.007) and AGPA (β = 0.555, P < 0.001) were significant positive predictors, while being a first‐year student (β = −0.217, P = 0.006) was a significant negative predictor. Collectively, these results suggest that attending a certain number of sessions may be required to gain a noticeable benefit from the program, and that first‐year students (particularly those with a lower level of academic preparedness) would likely stand to benefit from maximally using the program. End‐of‐semester surveys and reports indicate that the program had several additional benefits, both to the students taking the course and to the students who served as program leaders.

The First High Speed Research (HSR) Nozzle Symposium was hosted by NASA Lewis Research Center on November 17-19, 1992 in Cleveland, Ohio, and was sponsored by the HSR Source Noise Working Group. The purpose of this symposium was to provide a national forum for the government, industry, and university participants in the program to present and discuss important low noise nozzle research results and technology issues related to the development of appropriate nozzles for a commercially viable, environmentally compatible, U.S. High-Speed Civil Transport. The HSR Phase I research program was initiated in FY90 and is approaching the first major milestone (end of FY92) relative to an initial FAR 36 Stage 3 nozzle noise assessment. Significant research results relative to that milestone were presented. The opening session provided a brief overview of the Program and status of the Phase H plan. The next five sessions were technically oriented and highlighted recent significant analytical and experimental accomplishments. The last Session included a panel discussion by the Session Chairs, summarizing the progress seen to date and discussing issues relative to further advances in technology necessary to achieve the Program Goals. Attendance at the Symposium was by invitation only and included only industry, academic, and government participants who are actively involved in the High-Speed Research Program. The technology presented in this meeting is considered commercially sensitive.

Currently, one of the main objectives of human–animal interaction research is to demonstrate the benefits of animal assisted therapy (AAT) for specific profiles of patients or participants. The aim of this study is to assess the effect of an AAT program as an adjunct to a conventional 6–month psychosocial rehabilitation program for people with schizophrenia. Our hypothesis is that the inclusion of AAT into psychosocial rehabilitation would contribute positively to the impact of the overall program on symptomology and quality of life, and that AAT would be a positive experience for patients. To test these hypotheses, we compared pre–program with post–program scores for the Positive and Negative Syndrome Scale (PANSS) and the EuroQoL-5 dimensions questionnaire (EuroQol-5D), pre–session with post–session salivary cortisol and alpha–amylase for the last four AAT sessions, and adherence rates between different elements of the program. We conducted a randomized, controlled study in a psychiatric care center in Spain. Twenty–two institutionalized patients with chronic schizophrenia completed the 6–month rehabilitation program, which included individual psychotherapy, group therapy, a functional program (intended to improve daily functioning), a community program (intended to facilitate community reintegration) and a family program. Each member of the control group (n = 8) participated in one activity from a range of therapeutic activities that were part of the functional program. In place of this functional program activity, the AAT–treatment group (n = 14) participated in twice–weekly 1–h sessions of AAT. All participants received the same weekly total number of hours of rehabilitation. At the end of the program, both groups (control and AAT–treatment) showed significant improvements in positive and overall symptomatology, as measured with PANSS, but only the AAT–treatment group showed a significant improvement in negative symptomatology. Adherence to the AAT-treatment was significantly higher than overall adherence to the control group’s functional rehabilitation activities. Cortisol level was significantly reduced after participating in an AAT session, which could indicate that interaction with the therapy dogs reduced stress. In conclusion, the results of this small-scale RCT suggest that AAT could be considered a useful adjunct to conventional psychosocial rehabilitation for people with schizophrenia. PMID:27199859

"Thinking ethics": a novel, pilot, proof-of-concept program of integrating ethics into the Physiology curriculum in South India.

2017-06-01

Integrating medical ethics into the physiology teaching-learning program has been largely unexplored in India. The objective of this exercise was to introduce an interactive and integrated ethics program into the Physiology course of first-year medical students and to evaluate their perceptions. Sixty medical students (30 men, 30 women) underwent 11 sessions over a 7-mo period. Two of the Physiology faculty conducted these sessions (20-30 min each) during the routine physiology (theory/practicals) classes that were of shorter duration and could, therefore, accommodate the discussion of related ethical issues. This exercise was in addition to the separate ethics classes conducted by the Medical Ethics department. The sessions were open ended, student centered, and designed to stimulate critical thinking. The students' perceptions were obtained through a semistructured questionnaire and focused group discussions. The students found the program unique, thought provoking, fully integrated, and relevant. It seldom interfered with the physiology teaching. They felt that the program sensitized them about ethical issues and prepared them for their clinical years, to be "ethical doctors." Neutral observers who evaluated each session felt that the integrated program was relevant to the preclinical year and that the program was appropriate in its content, delivery, and student involvement. An ethics course taught in integration with Physiology curriculum was found to be beneficial, feasible, and compatible with Physiology by students as well as neutral observers.

Repetitive, active movement-based training promotes brain plasticity and motor recovery after stroke. Robotic therapy provides highly repetitive therapy that reduces motor impairment. However, the effect of assist-as-needed algorithms on patient participation and movement quality is not known. To analyze patient participation and motor performance during highly repetitive assist-as-needed upper limb robotic therapy in a retrospective study. Sixteen patients with sub-acute stroke carried out a 16-session upper limb robotic training program combined with usual care. The Fugl-Meyer Assessment (FMA) score was evaluated pre and post training. Robotic assistance parameters and Performance measures were compared within and across sessions. Robotic assistance did not change within-session and decreased between sessions during the training program. Motor performance did not decrease within-session and improved between sessions. Velocity-related assistance parameters improved more quickly than accuracy-related parameters. An assist-as-needed-based upper limb robotic training provided intense and repetitive rehabilitation and promoted patient participation and motor performance, facilitating motor recovery.

Multicultural or cultural competence education to address health care disparities using the traditional categorical approach can lead to inadvertent adverse consequences. Nontraditional approaches that address these drawbacks while promoting humanistic care are needed. In September 2014, the Cleveland VA Medical Center's Center of Excellence in Primary Care Education Transforming Outpatient Care (CoEPCE-TOPC) collaborated with the Cleveland Museum of Natural History (CMNH) to develop the Original Identity program, which uses a biocultural anthropologic framework to help learners recognize and address unconscious bias and starts with a discussion of humans' shared origins. The program comprises a two-hour initial learning session at the CMNH (consisting of an educational tour in a museum exhibit, a didactic and discussion section, and patient case studies) and a one-hour wrap-up session at the Louis Stokes Cleveland VA Medical Center. The authors delivered the complete Original Identity program four times between March and November 2015, with 30 CoEPCE-TOPC learners participating. Learners' mean ratings (n = 29; response rate: 97%) for the three initial learning session questions were consistently high (4.2-4.6) using a five-point scale. Comments to an open-ended question and during the audio-recorded wrap-up sessions also addressed the program objectives and key elements (e.g., bias, assumptions, stereotyping). The authors are completing additional qualitative analysis on the wrap-up session transcriptions to clarify factors that make the program successful, details of learners' experience, and any interprofessional differences in interpreting content. The authors believe this innovative addition to health care education warrants further research.

Min, Alice A.; Leetch, Aaron; Nuño, Tomas; Fiorello, Albert B.

2016-01-01

Purpose Emergency medicine residency programs have evaluated the use of Multiple Mini Interviews (MMIs) for applicants. The authors developed an MMI-style method called the Fast Interview Track (FIT) to predict an applicant's ‘fit’ within an individual residency program. Methods Applicants meet with up to five residents and are asked one question by each. Residents score the applicant using a Likert scale from 1 to 5 on two questions: ‘How well does the applicant think on his/her feet?’ and ‘How well do you think the applicant will fit in here?’. To assess how well these questions predicted a resident's ‘fit’, current residents scored fellow residents on these same questions. These scores were compared with the residents’ interview FIT scores. A postmatch survey of applicants who did not match at this program solicited applicants’ attitudes toward the FIT sessions. Results Among the junior class, the correlation between interview and current scores was significant for question 1 (rho=0.5192 [p=0.03]) and question 2 (rho=0.5753 [p=0.01]). Among seniors, Spearman's rho was statistically significant for question 2, though not statistically significant for question 1. The chi-square measure of high scores (4–5) versus low scores (1–3) found a statistically significant association between interview and current scores for interns and juniors. Of the 29 responses to the postmatch survey, 16 (55%) felt FIT sessions provided a good sense of the program's personality and only 6 (21%) disagreed. Nine (31%) felt FIT sessions positively impacted our program's ranking and 11 (38%) were ‘Neutral’. Only two (7%) reported that FIT sessions negatively impacted their ranking of our program. Conclusions FIT provided program leadership with a sense of an applicant's ‘fit’ within this program. Interview day scores correlated with scores received during residency. Most applicants report a positive experience with FIT sessions. FIT provides a useful tool to recruit applicants who fit with the residency program. PMID:26842824

We have designed a workshop breakout session and accompanying web based materials to assist geoscience departments in better preparing their students for professional careers following graduation. The session explores ways to obtain feedback about career preparation from employers and alumni that can be used to develop more effective curriculum, as well as departmental activities to better prepare students for employment opportunities. In addition, it identifies sources outside a department that can be used in the workforce preparation process and methods to assess any changes implemented to prepare students for the workforce. Concrete examples include feedback from a survey of recent (< 5 years) alumni at the University of Texas at El Paso, student run research meetings with built-in assessment opportunities, and a wealth of on-line resources. The session was initially tested in June 2009 at the Strengthening Your Strong Geoscience Department workshop. Comments from the June participants have been used to improve the session for the 2009-2010 “visiting workshop” program.

The formative evaluation of a standardized psychosocial education program for patients with Parkinson's disease (PD) and their caregivers. The results of the participation of the caregivers are presented next to the data of the patients. Caregivers (n = 137) and patients with PD (n = 151) participated in the 8-week program in separate groups. Measurements were performed on psychosocial problems (BELA-P/A-k), health state (EQ-5D VAS), quality of life (PDQ-39) and depression (SDS) 1 week before and 1 week after the program. Participants rated their mood on a visual analogue scale before and after each session, and they filled in an evaluation questionnaire after the last session. Scores on the BELA-P/A-k improved significantly on the 'bothered by scale' as well as the 'need for help scale'. No improvements were found on EQ-5D VAS, PDQ-39 and SDS. Mood ratings improved significantly after each session. Most participants evaluated the program as positive. Feedback led to improvements in the program, which are incorporated in a final manual. The program was feasible to run in the different countries. This exploratory study led to improvements in the program and recommendations for further research. A study on the effectiveness of the program is the next step.

The Accreditation Council for Graduate Medical Education recently emphasized the importance of systems-based practice and systems-based learning; however, successful models of collaborative quality improvement (QI) initiatives in residency training curricula are not widely available. Atlantic Health successfully conceptualized and implemented a QI collaborative focused on medication safety across eight residency training programs representing 219 residents. During a six-month period, key faculty and resident leaders from 8 (of 10) Atlantic Health residency training programs participated in three half-day collaborative learning sessions focused on improving medication reconciliation. Each session included didactic presentations from a multidisciplinary team of clinical experts as well as the application of principles that identified challenges, barriers, and solutions to QI initiatives. The learning sessions emphasized the fundamental principles of medication reconciliation, its critical importance as a vital part of patient handoff in all health care settings, and the challenges of achieving successful medication reconciliation improvement in light of work hours restrictions and patient loads. Each residency program developed a detailed implementation and measurement plan for individual "action learning" projects, using the Plan-Do-Study-Act method of improvement. Each program then implemented its QI project, and expert faculty (e.g., physicians, nurses, pharmacists, QI staff) provided mentoring between learning sessions. Several projects resulted in permanent changes in medication reconciliation processes, which were then adopted by other programs. The structure, process, and outcomes of this effort are described in detail.

The purpose of this intervention was to develop a therapeutic psycho-educational program that improves quality of life in children and adolescents who are experiencing chronic neurological illness, including epilepsy, and their parents, and to analyze the intervention's feasibility and efficacy and participants' satisfaction. Participants were eight children ( n = 8) and adolescents and their parents; participating children were experiencing chronic neurological illness with psychological comorbidity; children with intellectual impairment were excluded (IQ < 80). The program was carried out weekly for four sessions. In each of the 4 weeks, children's session content addressed self, emotion, coping skills, and finishing up, respectively; and parents' session content targeted family dynamic and emotional intervention, coping skills, childcare and education, and finishing up, respectively. Clinical psychologists administered psychological assessments (viz., Child Behavior Checklist, Pediatric Quality of Life Inventory, Parenting Stress Index, Beck Depression Inventory, Children's Depression Inventory, and Revised Children's Manifest Anxiety Scale) at pre- and post-intervention, and administered satisfaction surveys following the intervention. Participants' opinions about the program's necessity, contents, and process, and participants' overall program satisfaction were analyzed. Parents and children reported high levels of satisfaction with the program. Externalizing behavioral problems, anxiety/depression, and emotional functioning from quality of life showed improvement after the intervention. Although not statistically significant, total child stress trended downward from pre- to post-intervention. A four-session structured therapeutic psycho-educational program for children and adolescents with chronic neurological illness and their parents was successfully implemented, showing good compliance and high satisfaction and efficacy.

BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) and asthma depend on inhalers for management, but critical errors committed during inhaler use can limit drug effectiveness. Outpatient education in inhaler technique remains inconsistent due to limited resources and inadequate provider knowledge. OBJECTIVE: To determine whether a simple, two-session inhaler education program can improve physician attitudes toward inhaler teaching in primary care practice. METHODS: An inhaler education program with small-group hands-on device training was instituted for family physicians (FP) in British Columbia and Alberta. Sessions were spaced one to three months apart. All critical errors were corrected in the first session. Questionnaires surveying current inhaler teaching practices and attitudes toward inhaler teaching were distributed to physicians before and after the program. RESULTS: Forty-one (60%) of a total 68 participating FPs completed both before and after program questionnaires. Before the program, only 20 (49%) reported providing some form of inhaler teaching in their practices, and only four (10%) felt fully competent to teach patients inhaler technique. After the program, 40 (98%) rated their inhaler teaching as good to excellent. Thirty-four (83%) reported providing inhaler teaching in their practices, either by themselves or by an allied health care professional they had personally trained. All stated they could teach inhaler technique within 5 min. Observation of FPs during the second session by certified respiratory educators found that none made critical errors and all had excellent technique. CONCLUSION: A physician inhaler education program can improve attitudes toward inhaler teaching and facilitate implementation in clinical practices. PMID:26436910

Group exercise training programs were introduced as a strategy for improving health and fitness and potentially reducing dropout rates. This study examined the psychophysiological responses to group exercise training sessions. Twenty-seven adults completed two group exercise training sessions of moderate and vigorous exercise intensities in a random and counterbalanced order. The %HRR and the exertional and arousal responses to vigorous session were higher than those during the moderate session (p<0.05). Consequently, the affective responses to vigorous session were less pleasant than those during moderate session (p<0.05). These results suggest that the psychophysiological responses to group exercise training sessions are intensity-dependent. From an adherence perspective, interventionists are encouraged to emphasize group exercise training sessions at a moderate intensity to maximize affective responses and to minimize exertional responses, which in turn may positively affect future exercise behavior.

Family and patient psychoeducation have demonstrated significant improvement in clinical and social outcomes for patients suffering from severe mental disorders and their families. However, these evidence-based practices are not widely implemented at service delivery level and into routine clinical practice, especially in less developed countries. The aim of this article is to report the processes of development and implementation of a psychoeducational service for patients with severe mental illnesses and their families in Iran. The program was developed at Roozbeh Hospital in Tehran, Iran. A group of clinicians worked on the development phase of the program and drafting the manuals. Then, a series of workshops and supervision sessions were held to train group leaders for implementation of the group psychoeducation for patients and families. In the pilot phase, the services were delivered to two groups of patients and families, and then the manual was revised based on the feedback from group leaders and participants. The program consisted of eight 90-minute weekly patient group sessions and 6 weekly multiple family group sessions. Two manuals for patient education (schizophrenia and bipolar disorder) were developed. Several information sheets were developed and distributed during different sessions of family and patient psychoeducation related to the content of each session. Despite providing the hospital clinicians with the information regarding these new services, less than 10% of the admitted patients were referred by their clinicians. Feasibility and sustainability of the program are affected by a number of factors. Low referral rate of clinicians, limited resources of the hospital, issues related to stigma and logistic issues are barriers in implementation of these services. Administrators' and clinicians' understanding of the importance of patient and family psychoeducation seems to be crucial in sustainability of such programs in routine service delivery.

Air quality is the result of complex phenomena, among which the major role is played by human emissions of pollutants. Atmospheric processes act as determinants, e.g., modulating, dumping or amplifying the effects of emissions as an orchestra's director does with musical instruments. In this work, a series of small-scale and meso-scale meteorological determinants of air-quality are presented as they are observed in an area characterized by complex orography (Friuli Venezia Giulia, in the north-eastern side of Italy). In particular, attention is devoted to: i) meso-scale flows favouring the persistence of high concentrations of particulate matter; ii) meso-scale periodic flows (breezes) favouring high values of particulate matter; iii) local-scale thermodynamic behaviour favouring high atmospheric values of nitrogen oxides. The effects of these different classes of determinants are shown through comparisons between anthropic emissions (mainly traffic) and ground-based measurements. The relevance of complex orography (relatively steep relieves near to the sea) is shown for the meso-scale flows and, in particular, for local-scale periodic flows, which favour the increase of high pollutants concentrations mainly in summer, when the breezes regime is particularly relevant. Part of these results have been achieved through the ETS - Alpine Space EU project iMONITRAF!

Wind power: The new energy policy 1

1991-10-01

Increasing use of renewable energy sources is an important aspect of the new energy policy of the State government of Schleswig-Holstein. Technical and industrial innovation are involved. By expanding and developing these regionally available inexhaustible energy sources to generate electricity and heat, we are contributing to environmental protection and helping to reduce adverse affects on the climate. We are also taking our limited resources into account and expanding energy generation in a logical manner. Wind energy is the most attractive renewable energy source for Schleswig-Holstein because our State is well known for its strong winds and constant fresh breeze. For this reason the State government has made expansion of wind energy one of its primary areas of emphasis. The goals of our promotion measures includes ongoing technical and engineering development of wind energy facilities, increasing the level of use of the wind, and increasing the percentage of wind energy used for power generation. This brochure is intended to demonstrate the significance and possibilities of wind energy for our State, to outline the legal requirements for erecting wind energy facilities, and to explain the many promotion measures. It represents a favorable breeze for wind.

This study employed the Weather Research and Forecasting model with a single-layer urban canopy model to investigate the urban environment of a tropical city, Singapore. The coupled model was evaluated against available observational data from a sensor network and flux tower. The effects of land use type and anthropogenic heat (AH) on the thermal and wind environment were investigated with a series of sensitivity tests using an ensemble approach for low advection, high convective available potential energy, intermonsoon season cases. The diurnal cycle and spatial pattern of urban heat island (UHI) intensity and planetary boundary layer height were investigated. The mean UHI intensity peaked in the early morning at 2.2°C, reaching 2.4°C in industrial areas. Sea and land breezes developed during daytime and nighttime, respectively, with the former much stronger than the latter. The model predicted that sea breezes from different coastlines of the Malay Peninsula meet and converge, inducing strong updrafts. AH was found to play roles in all the processes studied, while the effect of different land use types was most pronounced during nighttime, and least visible near noon.

Although obesity among immigrants remains an important area of study given the increasing migrant population in Australia and other developed countries, research on factors amenable to intervention is sparse. The aim of the study was to develop a culturally-competent obesity prevention program for sub-Saharan African (SSA) families with children aged 12-17 years using a community-partnered participatory approach. A community-partnered participatory approach that allowed the intervention to be developed in collaborative partnership with communities was used. Three pilot studies were carried out in 2008 and 2009 which included focus groups, interviews, and workshops with SSA parents, teenagers and health professionals, and emerging themes were used to inform the intervention content. A cultural competence framework containing 10 strategies was developed to inform the development of the program. Using findings from our scoping research, together with community consultations through the African Review Panel, a draft program outline (skeleton) was developed and presented in two separate community forums with SSA community members and health professionals working with SSA communities in Melbourne. The 'Healthy Migrant Families Initiative (HMFI): Challenges and Choices' program was developed and designed to assist African families in their transition to life in a new country. The program consists of nine sessions, each approximately 1 1/2 hours in length, which are divided into two modules based on the topic. The first module 'Healthy lifestyles in a new culture' (5 sessions) focuses on healthy eating, active living and healthy body weight. The second module 'Healthy families in a new culture' (4 sessions) focuses on parenting, communication and problem solving. The sessions are designed for a group setting (6-12 people per group), as many of the program activities are discussion-based, supported by session materials and program resources. Strong partnerships and participation by SSA migrant communities enabled the design of a culturally competent and evidence-based intervention that addresses obesity prevention through a focus on healthy lifestyles and healthy families. Program implementation and evaluation will further inform obesity prevention interventions for ethnic minorities and disadvantaged communities.

The present study examined the influence of group positive parenting program on parental stress of mothers of children with attention-deficient/hyperactivity disorder. Mothers of 13 children aged four to ten years, who met attention-deficient/hyperactivity disorder diagnosis by assessment of a child psychiatrist and clinical psychologist were selected from two child and adolescent psychiatric clinics of Tehran. To control the drug effects, researchers chose children who took methylphenidate (Ritalin) since six months before. The group programs consisted of a six-weekly session of two hours duration, plus two telephone educational sessions, each one lasting 15 minutes. Group was run by an experienced clinician who followed a specific training manual to ensure a standard format. These sessions continued with eight participants, because five of 13 mothers did not attend the classes. The results indicated that group positive parenting program caused mothers to experience lower stress. A two-month follow-up showed the stable efficiency of the program. This study revealed that the competency feeling and couples' harmony--as intervening variables--about nurturing the child were improved.

The issues discussed in this paper are the result of a 10-week study by the Space Solar Power Program design project members and the Space Transportation Group at the International Space University (ISU) summer session of 1992 to investigate new paradigms in space propulsion and how those paradigms might reduce the costs for large space programs. The program plan was to place a series of power satellites in Earth orbit. Several designs were studied where many kW, MW or GW of power would be transmitted to Earth or to other spacecraft in orbit. During the summer session, a space solar power system was also detailed and analyzed. At ISU, the focus of the study was to foster and develop some of the new paradigms that may eliminate the barriers to low cost for space exploration and exploitation. Many international and technical aspects of a large multinational program were studied. Environmental safety, space construction and maintenance, legal and policy issues of frequency allocation, technology transfer and control and many other areas were addressed.

BACKGROUND: Primary care office spirometry can improve access to testing and concordance between clinical practice and asthma guidelines. Compliance with test quality standards is essential to implementation. OBJECTIVE: To evaluate the quality of spirometry performed onsite in a regional primary care asthma program (RAP) by health care professionals with limited training. METHODS: Asthma educators were trained to perform spirometry during two 2 h workshops and supervised during up to six patient encounters. Quality was analyzed using American Thoracic Society (ATS) 1994 and ATS/European Respiratory Society (ERS) 2003 (ATS/ERS) standards. These results were compared with two regional reference sites: a primary care group practice (Family Medical Centre [FMC], Windsor, Ontario) and a teaching hospital pulmonary function laboratory (London Health Sciences Centre [LHSC], London, Ontario). RESULTS: A total of 12,815 flow-volume loops (FVL) were evaluated: RAP – 1606 FVL in 472 patient sessions; reference sites – FMC 4013 FVL in 573 sessions; and LHSC – 7196 in 1151 sessions. RAP: There were three acceptable FVL in 392 of 472 (83%) sessions, two reproducible FVL according to ATS criteria in 428 of 469 (91%) sessions, and 395 of 469 (84%) according to ATS/ERS criteria. All quality criteria – minimum of three acceptable and two reproducible FVL according to ATS criteria in 361 of 472 (77%) sessions and according to ATS/ERS criteria in 337 of 472 (71%) sessions. RAP met ATS criteria more often than the FMC (388 of 573 [68%]); however, less often than LHSC (1050 of 1151 [91%]; P<0.001). CONCLUSIONS: Health care providers with limited training and experience operating within a simple quality program achieved ATS/ERS quality spirometry in the majority of sessions in a primary care setting. The quality performance approached pulmonary function laboratory standards. PMID:22891184

It is not clear whether patient's psycho-education enhances compliance to antipsychotic treatments and reduces the number of relapses. Here we investigated the impact of a new psycho-educational program (SOLEDUC) on the one- and two-years rate of relapse (primary outcome measure) and a number of clinical assessments (secondary outcome measures). This was a multicentric French clinical trial (51 centers) of Phase IV, open, controlled, randomized, consisting in two parallel groups: the Soleduc group (N=111) and the control group (N=109). All subjects received a variable dose over the 2-year period of the same antipsychotic drug (amisulpride). Soleduc consisted of a 7-session program (1h per session), presented three times (at baseline, 6-months and 12-months). Patients in the control group received a non-specific psychosocial training for an equivalent period of time. The models of Andersen-Gill (AG) and Prentice, Williams and Peterson (PWP) were used to analyze relapses. Patients in the Soleduc group attended 14.8+/-6.1 sessions (mean+/-SD), including 17 patients who never attended a session. Intent to treat analysis showed less patients relapsing in the Soleduc group as compared to the control group (21.6% versus 28.4% after 1 year and 84.4% versus 90.8% after 2years), but the differences were not statistically significant. Relapse risk was significantly reduced for patients who followed at least 7 modules (p=0.015 AG-test; p<0.001 PWP-test). In conclusion, no significant differences in relapse rates were found between patients attending the Soleduc program and the control group. Attendance of at least 7 out of 21 program sessions was required to see a modest, but significant two-year relapse prevention in schizophrenia. Other well designed studies are required to evaluate the medical impact of patient's education programs.

Inuit women's stories of strength: informing Inuit community-based HIV and STI prevention and sexual health promotion programming

Background There is a dearth of literature to guide the development of community-based HIV and sexually transmitted infection (STI) prevention and sexual health promotion programs within Inuit communities. Objective The aim of this study was to create a dialogue with Inuit women to address the lack of information available to inform programming to improve the sexual health of Inuit women, their families, and their communities in the Canadian Arctic. Design This study used Indigenous methodologies and methods by drawing from Inuit Qaujimajatuqangit and postcolonial research theory in a framework of Two-Eyed Seeing, and using storytelling sessions to gather data. Community-based participatory research principles informed the design of the study, ensuring participants were involved in all stages of the project. Nine storytelling sessions took place with 21 Inuit women aged 18–61 years. Storytelling sessions were audio recorded and transcribed verbatim, and Atlas.ti aided in the organization of the data for collaborative thematic analysis within three participatory analysis sessions with 13 of the participating women. Results From the storytelling and analysis sessions, five major themes emerged: (a) the way it used to be, (b) change, (c) family, (d) intimate relationships and (e) holistic strategies. Participating women emphasized that HIV and STI prevention and sexual health promotion programming needs to take a holistic, community-wide, family-focused and youth-centred approach within their communities. Conclusion Participants identified several important determinants of sexual health and shared ideas for innovative approaches they believe will work as prevention efforts within their communities. This article specifically focuses on key characteristics of programming aimed at STI and HIV prevention and sexual health promotion that were identified throughout participants’ stories. This study has provided a narrative to complement the epidemiological data that highlight the urgent need for prevention programming. PMID:27938640

Weather Research and Forecasting Model Sensitivity Comparisons for Warm Season Convective Initiation

Watson, Leela R.; Hoeth, Brian; Blottman, Peter F.

2007-01-01

Mesoscale weather conditions can significantly affect the space launch and landing operations at Kennedy Space Center (KSC) and Cape Canaveral Air Force Station (CCAFS). During the summer months, land-sea interactions that occur across KSC and CCAFS lead to the formation of a sea breeze, which can then spawn deep convection. These convective processes often last 60 minutes or less and pose a significant challenge to the forecasters at the National Weather Service (NWS) Spaceflight Meteorology Group (SMG). The main challenge is that a "GO" forecast for thunderstorms and precipitation at the Shuttle Landing Facility is required at the 90 minute deorbit decision for End Of Mission (EOM) and at the 30 minute Return To Launch Site (RTLS) decision. Convective initiation, timing, and mode also present a forecast challenge for the NWS in Melbourne, FL (MLB). The NWS MLB issues such tactical forecast information as Terminal Aerodrome Forecasts (TAF5), Spot Forecasts for fire weather and hazardous materials incident support, and severe/hazardous weather Watches, Warnings, and Advisories. Lastly, these forecasting challenges can also affect the 45th Weather Squadron (45 WS), which provides comprehensive weather forecasts for shuttle launch, as well as ground operations, at KSC and CCAFS. The need for accurate mesoscale model forecasts to aid in their decision making is crucial. This study specifically addresses the skill of different model configurations in forecasting warm season convective initiation. Numerous factors influence the development of convection over the Florida peninsula. These factors include sea breezes, river and lake breezes, the prevailing low-level flow, and convergent flow due to convex coastlines that enhance the sea breeze. The interaction of these processes produces the warm season convective patterns seen over the Florida peninsula. However, warm season convection remains one of the most poorly forecast meteorological parameters. To determine which configuration options are best to address this specific forecast concern, the Weather Research and Forecasting (WRF) model, which has two dynamical cores - the Advanced Research WRF (ARW) and the Non-hydrostatic Mesoscale Model (NMM) was employed. In addition to the two dynamical cores, there are also two options for a "hot-start" initialization of the WRF model - the Local Analysis and Prediction System (LAPS; McGinley 1995) and the Advanced Regional Prediction System (ARPS) Data Analysis System (ADAS; Brewster 1996). Both LAPS and ADAS are 3- dimensional weather analysis systems that integrate multiple meteorological data sources into one consistent analysis over the user's domain of interest. This allows mesoscale models to benefit from the addition of highresolution data sources. Having a series of initialization options and WRF cores, as well as many options within each core, provides SMG and MLB with considerable flexibility as well as challenges. It is the goal of this study to assess the different configurations available and to determine which configuration will best predict warm season convective initiation.

The Great Observatories Origins Deep Survey (GOODS) is an anthology of observing programs that are creating a rich, public, multiwavelength data set for studying galaxy formation and evolution. GOODS is observing two fields, one in each hemisphere, with extremely deep imaging and spectroscopy using the most powerful telescopes in space and on the ground. The GOODS Spitzer Legacy Science Program completes the trio of observations from NASA's Great Observatories, joining already-completed GOODS data from Chandra and Hubble. Barring unforeseen difficulties, the GOODS Spitzer observing program will have been completed by the end of 2004, and the first data products will have been released to the astronomical community. In this Special Oral Session, and in an accompanying poster session, the GOODS team presents early scientific results from this Spitzer Legacy program, as well as new research based on other GOODS data sets. I will introduce the session with a brief description of the Legacy observations and data set. Support for this work, part of the Spitzer Space Telescope Legacy Science Program, was provided by NASA through Contract Number 1224666 issued by the Jet Propulsion Laboratory, California Institute of Technology under NASA contract 1407.

While Internet interventions can improve health behaviors, their impact is limited by program adherence. Supporting program adherence through telephone counseling may be useful, but there have been few direct tests of the impact of support. We describe a Telephone Motivational Interviewing (MI) intervention targeting adherence to an Internet intervention for drivers with Type 1 Diabetes, DD.com, and compare completion of intervention benchmarks by those randomized to DD.com plus MI vs. DD.com only. The goal of the pre-intervention MI session was to increase the participant's motivation to complete the Internet intervention and all its assignments, while the goal of the post-treatment MI session was to plan for maintaining changes made during the intervention. Sessions were semi-structured and partially scripted to maximize consistency. MI Fidelity was coded using a standard coding system, the MITI. We examined the effects of MI support vs. no support on number of days from enrollment to program benchmarks. Results show that MI sessions were provided with good fidelity. Users who received MI support completed some program benchmarks such as Core 4 (t176 df= -2.25; p<.03) and 11 of 12 monthly driving diaries significantly sooner, but support did not significantly affect time to intervention completion (t177 df= -1.69; p<. 10) or rates of completion. These data suggest that there is little benefit to therapist guidance for Internet interventions including automated email prompts and other automated minimal supports, but that a booster MI session may enhance collection of follow-up data.

This mixed methods study sought to evaluate the outcomes of an integrative Reiki volunteer program in an academic medical oncology center setting. We used de-identified program evaluation data to perform both quantitative and qualitative analyses of participants' experiences of Reiki sessions. The quantitative data were collected pre- and postsession using a modified version of the distress thermometer. The pre- and postsession data from the distress assessment were analyzed using a paired Student's : test. The qualitative data were derived from written responses to open-ended questions asked after each Reiki session and were analyzed for key words and recurring themes. Of the 213 pre-post surveys of first-time sessions in the evaluation period, we observed a more than 50% decrease in self-reported distress (from 3.80 to 1.55), anxiety (from 4.05 to 1.44), depression (from 2.54 to 1.10), pain (from 2.58 to 1.21), and fatigue (from 4.80 to 2.30) with P < .001 for all. Using conservative estimates that treat missing data as not endorsing Reiki, we found 176 (82.6%) of participants liked the Reiki session, 176 (82.6%) found the Reiki session helpful, 157 (73.7%) plan to continue using Reiki, and 175 (82.2%) would recommend Reiki to others. Qualitative analyses found that individuals reported that Reiki induced relaxation and enhanced spiritual well-being. An integrative Reiki volunteer program shows promise as a component of supportive care for cancer patients. More research is needed to evaluate and understand the impact that Reiki may have for patients, caregivers, and staff whose lives have been affected by cancer.

Although the global nursing faculty shortage has led to increasing reliance upon sessional staff, limited research has explored the impact of these sessional staff on the quality of teaching in higher education. We aim to examine differences in (a) student satisfaction with sessional and tenured staff and (b) assessment scores awarded by sessional and tenured staff in students' written assignments. A comparative study method was used. Participants were recruited from students enrolled in the three nursing practice subjects across the 3 years of the baccalaureate program in an Australian university during the second semester of 2008. This study collected student data via an online version of the Perceptions of Teaching and Course Satisfaction scale and compared the grades awarded by sessional and tenured academics for a written assessment in a single assignment in each of the nursing practice subjects. Of the 2,045 students enrolled in the nursing practice subjects across the 3 years of the bachelor of nursing (BN) program, 566 (28%) completed the online teaching and course satisfaction survey, and 1,972 assignment grades (96%) were available for analysis. Compared with tenured academics, sessional teachers received higher rating on students' perception on teaching satisfaction by students in Year 1 (p= .021) and Year 2 (p= .002), but not by students in Year 3 (p= .348). Following the same trend, sessional teachers awarded higher assignment grades to students in Year 1 (p < .001) and Year 2 (p < .001) than tenured academics, with no significant disparity in grades awarded to students in Year 3. The higher grades awarded by sessional teachers to 1st- and 2nd-year students could be one explanation for why these teachers received higher student ratings than tenured teachers. Not discounting the possibility of grade inflation by sessional staff, it could be that tenured teachers have a higher expectation for the quality of students' work, and hence were more stringent in their assessment grading. Sessional teachers did not receive a higher rating from 3rd-year students, and this could be attributed to a change in student perception as they progress through the course, valuing a broader and more professional aspect of nursing knowledge, which is more likely to be the strength of tenured staff. These findings highlight a need for the development and implementation of strategies to facilitate the inclusion of sessional staff teaching in a BN program, in order to prepare graduate nurses that are well-equipped for clinical practice. © 2010 Sigma Theta Tau International.

To address the translational research question regarding the optimal intervention "dose" to produce the most cost-effective rate of weight loss, we conducted the Drop It At Last (DIAL) study. DIAL is a 6-month pilot randomized trial to examine the efficacy of phone-based weight loss programs with varying levels of treatment contact (10 vs. 20 sessions) in comparison to self-directed treatment. Participants were recruited from the community via mailings and advertisement. Participants were 63 adults with a body mass index between 30 and 39 kg/m(2). Participants received a standard set of print materials and were randomized to either: (1) self-directed treatment; (2) 10 phone coaching sessions; or (3) 20 phone coaching sessions. Measured height, weight, and psychosocial and weight-related self-monitoring measures were collected at baseline and follow-up. General linear models were used to examine 6-month treatment group differences in weight loss and in psychosocial and behavioral measures. Weight losses were -2.3, -3.2, and -4.9 kg in the self-directed, 10-session, and 20-session groups, respectively (p < .21). Participants who completed 10 or more sessions lost more weight (-5.1 kg) compared to those completed four or fewer sessions (-.3 kg, p < .04). Phone-based weight loss program participation is associated with modest weight loss. The optimal dose and timing of intervention warrant further study.

When treating anxious patients with co-occurring depression, research demonstrates that both types of symptoms independently improve. The current analyses examined how reductions in anxiety and depression may be interrelated both during treatment, as well as over time following treatment. Participants were 503 individuals with one or more DSM-IV anxiety disorders who completed a collaborative care anxiety management program. Anxiety and depression were assessed at each treatment session (i.e., session by session data) and also at 6, 12, and 18-month post-baseline assessments (i.e., long-term outcomes data). Mediation analyses examined changes in symptoms in session by session data and long-term outcomes data. Anxiety and depression changed reciprocally in session by session data; change in anxiety mediated change in depression to a greater extent than vice versa. In the long-term outcomes data, change in anxiety mediated change in depression. However, the reverse mediation model of the long-term outcomes period revealed that accounting for changes in depression altered the effect of time on anxiety. Thus, temporal change during active treatment may share similarities with those related to maintaining gains after treatment, although differences arose in the reverse mediation models. Limitations of the methodology and implications of anxiety treatment for depression outcomes are discussed. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

To illustrate the continuity of care afforded by a standardized locomotor training program across a multisite network setting within the Christopher and Dana Reeve Foundation NeuroRecovery Network (NRN). Single patient case study. Two geographically different hospital-based outpatient facilities. This case highlights a 25-year-old man diagnosed with C4 motor incomplete spinal cord injury with American Spinal Injury Association Impairment Scale grade D. Standardized locomotor training program 5 sessions per week for 1.5 hours per session, for a total of 100 treatment sessions, with 40 sessions at 1 center and 60 at another. Ten-meter walk test and 6-minute walk test were assessed at admission and discharge across both facilities. For each of the 100 treatment sessions percent body weight support, average, and maximum treadmill speed were evaluated. Locomotor endurance, as measured by the 6-minute walk test, and overground gait speed showed consistent improvement from admission to discharge. Throughout training, the patient decreased the need for body weight support and was able to tolerate faster treadmill speeds. Data indicate that the patient continued to improve on both treatment parameters and walking function. Standardization across the NRN centers provided a mechanism for delivering consistent and reproducible locomotor training programs across 2 facilities without disrupting training or recovery progression.

Saenz, Rafael; Skledar, Susan J; Yourich, Bryan; Mark, Scott M

2010-08-15

An educational program for pharmacists in a multifacility health care setting is described. The expansion of pharmacy services at a university medical center from a centralized to a decentralized, unit-based model created the need for enhanced education of staff pharmacists. A steering committee with pharmacy department and school of pharmacy representation surveyed educational and professional needs related to the expanded services. Pharmacists indicated that they needed an educational program that was comprehensive, interactive, and accessible to all shifts. Pharmacy school clinical faculty members provided most of the initial educational sessions, which combined didactic presentations and case-based discussion. The needs survey was used in selecting topics that were most relevant to the pharmacists' expanded practice. Each major topic was covered in a series of one-hour sessions held at two-week intervals and scheduled at a time convenient for afternoon-shift pharmacists. Incentives were offered to encourage participation. The live presentations were recorded with video-streaming technology and made available via the Internet to pharmacists on all shifts in all facilities of the health system as well as to faculty members. Since program implementation in 2005, attendance at the live sessions has averaged 25. In postimplementation surveys, pharmacists indicated that the program was meeting their needs and improving patient care. Since 2008, pharmacists have been able to earn continuing-education (CE) credit for the sessions. A collaborative educational series with online access, clinical content, and CE credit has been effective in meeting pharmacists' needs in a multifacility health care setting.

Coastlines around the world are under ever-increasing pressure due to population trends, commerce, and geophysical processes like tropical storms and erosion. This multi-institutional field campaign was conducted to improve our understanding of complex nearshore processes under varying forcing conditions on a microtidal, sandy beach located in Sisal, Yucatan from 3/27 to 4/12/2014. Hydrodynamics, morphodynamics, and textural variability were investigated during: (1) a cold front event (referred to as El-Norte); (2) land breeze (LB); and (3) sea breeze (SB). The instrumentation layout included three surf/swash zone cross-shore transects where water elevation, suspended sediment concentration, bed load, and current velocities were measured, as well as several offshore ADCP for hydrodynamic measurements. TKE, τb, ɛ and were estimated using the data obtained from surf zone ADV. In addition, Hs and Tsin the surf zone were computed using measurements from ADV pressure sensors, while a separate pressure transducer was used to obtain water free-surface elevation within the swash zone. During SB cycles the study area experienced wind velocities reaching up to 12ms-1, and 15ms-1 during El-Norte. Elevated wind stress during El-Norte resulted in Hs of 1.5m and 0.6m in water depths of 10m and 0.4m, respectively. Surface sediment grab samples during SB/LB cycles showed that the swash zone had a moderately well sorted distribution with a mean grain size of 0.5mm, while poor sorting and a mean grain size of 0.7mm were found during El-Norte. Additionally, measured bathymetry data showed evidence for offshore sandbar migration during strong offshore currents (0.4ms-1) during El-Norte, while onshore sandbar migration was evident during SB/LB periods (0.3ms-1 and 0.1ms-1, respectively). This study highlights how different weather forcing conditions affect hydrodynamics, morphodynamics, and textural variability on a sandy beach. Aside from furthering our knowledge on these complex processes, the findings may lead to improved coastal management strategies for sandy coastlines.

Observational Evidence For The Comet-Like Heliosphere

The shape of the heliosphere is a subject of ongoing debate. The traditional comet-like image has recently been challenged by ideas of croissant- or bubble-like forms. Here we seek to resolve this debate by confronting available observational evidence with global modeling. Several MHD models of a comet-like heliosphere were used to simulate the radius and center of the IBEX Ribbon to fit the direction and intensity of the interstellar magnetic field (ISMF). These models assumed the secondary ENA emission mechanism, which was recently strengthened due to direct measurement of the distance to the Ribbon source most likely just beyond the heliopause. The same mechanism explains the dependence of the Ribbon center position on energy due to the latitudinal structure of solar wind. The obtained ISMF vector agrees among these models and is consistent with the draped IMF measured by Voyager. Independently, we have shown by modeling that the Warm Breeze discovered by IBEX is naturally created in the outer heliosheath due to charge-exchange between interstellar He+ ions and He atoms. Now we simulate the Warm Breeze for various directions and intensities of the local IMF and we find that the simulation results are in best agreement with IBEX observations for the IMF vector obtained from the above-mentioned Ribbon analyses and Voyager measurements. These arguments, along with the co-planarity of the inflow directions of interstellar neutral H, He, O, and the Warm Breeze, directions of the Ribbon center and ISMF, as well as measurements of the plasma flow directions in the IHS by Voyager 2 indicate the existence of a common plane of approximate mirror symmetry of the heliosphere, defined by the directions of ISMF and the Sun's motion through the local interstellar medium. This suggests that the global structure of the outer heliosphere mostly results from the conditions in the local interstellar medium and the Sun's velocity. This evidence, obtained from very different spacecraft and measurement techniques, supports a homogeneous and consistent picture of the heliosphere with a comet-like shape and organized by the plane of approximate mirror symmetry.

In situ airborne measurements of aerosol optical properties during photochemical pollution events

NASA Astrophysics Data System (ADS)

Mallet, M.; van Dingenen, R.; Roger, J. C.; Despiau, S.; Cachier, H.

2005-02-01

Dry aerosol optical properties (scattering, absorbing coefficients, and single scattering albedo) were derived from in situ airborne measurements during two photochemical pollution events (25 and 26 June) observed during the Experience sur Site pour Contraindre les Modeles de Pollution atmospherique et de Transport d'Emissions (ESCOMPTE) experiment. Two flights were carried out during daytime (one during the morning and one at noon) over a domain, allowing the investigation of how an air pollution event affects the particle optical properties. Both horizontal distribution and vertical profiles are presented. Results from the horizontal mapping show that plumes of enhanced scattering and absorption are formed in the planetary boundary layer (PBL) during the day in the sea breeze-driven outflow of the coastal urban-industrial area of Marseille-Fos de Berre. The domain-averaged scattering coefficient (at 550 nm) over land σs changes from 35 (28) Mm-1 during land breeze to 63 (43) Mm-1 during sea breeze on 25 June (26 June), with local maxima reaching > 100 Mm-1. The increase in the scattering coefficient is associated with new particle formation, indicative of secondary aerosol formation. Simultaneously, the domain-averaged absorption coefficient increases from 5.6 (3.4) Mm-1 to 9.3 (8.0) Mm-1. The pollution plume leads to strong gradients in the single scattering albedo ωo over the domain studied, with local values as low as 0.73 observed inside the pollution plume. The role of photochemistry and secondary aerosol formation during the 25 June case is shown to increase ωo and to make the aerosol more `reflecting' while the plume moves away from the sources. The lower photochemical activity, observed in the 26 June case, induces a relatively higher contribution of black carbon, making the aerosol more absorbing. Results from vertical profiles at a single near-urban location in the domain indicate that the changes in optical properties happen almost entirely within the PBL. No significant variation of σs, σa, and ωo is observed in the upper layer (1-3 km), where the aerosol optical properties are considered to be well mixed.

The use of fractionated fly ash of thermal power plants as binder for production of briquettes of coke breeze and dust

NASA Astrophysics Data System (ADS)

2017-11-01

In this paper, we propose to use the slag and ash material of thermal power plants (TPP) operating on pulverized coal fuel. The elemental and chemical composition of fly ash of five Kuzbass thermal power plants differs insignificantly from the composition of the mineral part of coking coal because coke production uses a charge, whose composition defines the main task: obtaining coke with the required parameters for production of iron and steel. These indicators are as follows: CRI reactivity and strength of the coke residue after reaction with CO2 - CSR. The chemical composition of fly ash of thermal power plants and microsilica with bulk density of 0.3-0.6 t/m3 generated at production of ferroalloys was compared. Fly ash and microsilica are the valuable raw material for production of mineral binder in manufacturing coke breeze briquettes (fraction of 2-10 mm) and dust (0-200 μm), generated in large quantities during coking (up to 40wt%). It is shown that this binder is necessary for production of smokeless briquettes with low reactivity, high strength and cost, demanded for production of cupola iron and melting the silicate materials, basaltic rocks in low-shaft furnaces. It is determined that microsilica contains up to 90% of silicon oxide, and fly ash contains up to 60% of silicon oxide and aluminum oxide of up to 20%. On average, the rest of fly ash composition consists of basic oxides. According to calculation by the VUKHIN formula, the basicity index of briquette changes significantly, when fly ash is introduced into briquette raw material component as a binder. The technology of coke briquette production on the basis of the non-magnetic fraction of TPP fly ash in the ratio from 3.5:1 to 4.5:1 (coke breeze : coke dust) with the addition of the binder component to 10% is proposed. The produced briquettes meet the requirements by CRI and require further study on CSR requirements.

Warm Breeze due to Charge Exchange Collisions Between Neutral He Atoms and He+ Ions in the Outer Heliosheath.

NASA Astrophysics Data System (ADS)

Kubiak, M. A.; Bzowski, M.; Czechowski, A.; Grygorczuk, J.

2017-12-01

We simulated the signal due to neutral He atoms, observed by Interstellar Boundary Explorer (IBEX), assuming that charge exchange collisions between neutral He atoms and He+ ions operate everywhere between the heliopause and a distant source region in the local interstellar cloud (LIC). We chose the limiting distance of calculations at 5000 AU, where the neutral and charged components are in thermal equilibrium. From that distance we integrated the signal for test particles that we know they reach the IBEX detector, calculating for each particle the balance of losses and gains in the LIC, the ionization losses inside the HP, and the distribution function at 5000 AU. The resulting statistical weights were integrated over speed, inflow direction, collimator transmission, observation times, and IBEX spin angle bins to simulate the count rate actually observed by IBEX. We simulated several test cases of the plasma flow within the outer heliosheath and investigated the signal generation for plasma flows both in the presence and in the absence of the interstellar magnetic field. We found that a signal in the portion of IBEX data identified as due to the Warm Breeze does not arise when a homogeneous plasma flow in front of the heliopause is assumed. However, it appears immediately when any reasonable disturbance in the plasma flow due to the presence of the heliosphere is assumed. We obtained a good qualitative agreement between the data and the simulations for a model flow with the velocity vector of the unperturbed gas and the direction and intensity of magnetic field adopted from recent determinations. We conclude that direct-sampling observations of neutral He atoms at 1 AU from the Sun are a sensitive tool for investigating the flow of interstellar matter in the outer heliosheath; the Warm Breeze is indeed the secondary population of interstellar helium, as it was hypothesized earlier; the WB signal is consistent with that predicted by comet-like models of the heliosphere with a distortion from axial symmetry by the interstellar magnetic field of 3 microgauss, directed close to the Ribbon direction.

Increasing girls’ physical activity during an organised youth sport basketball program: a randomised controlled trial protocol

PubMed Central

2014-01-01

Background Participation in organised youth sports (OYS) has been recommended as an opportunity to increase young peoples’ moderate-to-vigorous physical activity (MVPA) levels. Participants, however, spend a considerable proportion of time during OYS inactive. The purpose of this study, therefore, was to investigate whether coaches who attended coach education sessions (where education on increasing MVPA and decreasing inactivity during training was delivered) can increase players’ MVPA during training sessions over a 5-day basketball program compared to coaches who did not receive coach education sessions. Methods/design A convenience sample of 80 female players and 8 coaches were recruited into the UWS School Holiday Basketball Program in Greater Western Sydney, Australia. A two-arm, parallel-group randomised controlled trial was employed to investigate whether coaches who attended 2 coach education sessions (compared with a no-treatment control) can increase their players’ MVPA during training sessions over a 5-day basketball program. Objectively measured physical activity, directly observed lesson context and leader behaviour, player motivation, players’ perceived autonomy support, and coaching information (regarding training session planning, estimations on player physical activity and lesson context during training, perceived ability to modify training sessions, perceived importance of physical activity during training, intention to increase physical activity/reduce inactivity, and likelihood of increasing physical activity/reducing inactivity) were assessed at baseline (day 1) and at follow-up (day 5). Linear mixed models will be used to analyse between arm differences in changes from baseline to follow-up on all outcomes. Discussion The current trial protocol describes, to our knowledge, the first trial conducted in an OYS context to investigate the efficacy of an intervention, relative to a control, in increasing MVPA. This study’s findings will provide evidence to inform strategies targeting coaches to increase MVPA in OYS, which could have major public health implications, given the high proportion of children and adolescents who participate in OYS globally.

Improving Social Cognition in People with Schizophrenia with RC2S: Two Single-Case Studies.

PubMed

Peyroux, Elodie; Franck, Nicolas

2016-01-01

Difficulties in social interactions are a central characteristic of people with schizophrenia, and can be partly explained by impairments of social cognitive processes. New strategies of cognitive remediation have been recently developed to target these deficits. The RC2S therapy is an individualized and partly computerized program through which patients practice social interactions and develop social cognitive abilities with simulation techniques in a realistic environment. Here, we present the results of two case-studies involving two patients with schizophrenia presenting with specific profiles of impaired social cognition. Each patient completed three baseline sessions, 14 treatment sessions, and 3 follow-up sessions at the end of the therapy - and for 1 patient, another 3 sessions 9 months later. We used a multiple baseline design to assess specific components of social cognition according to the patients' profiles. Functioning and symptomatology were also assessed at the end of the treatment and 6 months later. Results highlight significant improvements in the targeted social cognitive processes and positive changes in functioning in the long term. The RC2S program seems, thus, to be a new useful program for social cognitive remediation in schizophrenia.

We aimed to assess the feasibility of delivering a music therapy program on adolescent psychiatric wards. We undertook a mixed-methods evaluation of a pilot program. Various active and receptive techniques were employed in group music therapy sessions delivered as part of a structured clinical program. Data collected in interviews with participants and staff and feedback questionnaires were thematically and descriptively analysed and triangulated. Data from 62 questionnaires returned by 43 patients who took part in 16 music therapy sessions, and seven staff, evidenced strong support for music therapy. Patients typically reported experiencing sessions as relaxing, comforting, uplifting, and empowering; >90% would participate by choice and use music therapeutically in the future. Staff endorsed music therapy as valuable therapeutically, reporting that patients engaged enthusiastically and identified sessions as improving their own moods and ward milieu. Integration of music therapy in inpatient treatment of adolescents is feasible and acceptable, and is valued by staff and patients as a complement to 'talking therapies'. Participation is enjoyed and associated with outcomes including improvement in mood, expression of feelings and social engagement consistent with recovery. © The Royal Australian and New Zealand College of Psychiatrists 2015.

Educational needs of employed family caregivers of older adults: Evaluation of a workplace project.

PubMed

Curry, Linda Cox; Walker, Charles; Hogstel, Mildred O

2006-01-01

Family members provide 80% of care for older adults in the United States. Many family caregivers are employed either full or part time. For employed caregivers, personal health, job performance, and the ability to advance their career are affected by the weight of their caregiving responsibilities. Some find it necessary to quit their jobs. Employed caregivers report a need for caregiving information; however, they seldom think of their workplace as a valuable resource. Results of the second of a 3-phase research and service project are discussed. Based on a needs assessment completed by employees of a large institution, educational sessions were offered during 3 consecutive months. Thirty-five employees attended 1 or more sessions. The sessions were evaluated highly on a 5-point Likert-type scale for usefulness of information, quality of presentation, and value of session. Sharing project results with the employing institution's human resources department yielded commitment to integrate caregiver education and referral into a newly organized work-life program. When properly managed, such workplace programs can provide needed assistance to employed caregivers. A nurse working with older adults is an ideal provider to initiate and manage this kind of program.

The National Sexual Assault Online Hotline (NSAOH) is a new model for delivery of rape and sexual assault crisis services through a secure, confidential chat-based online hotline. This paper presents a program evaluation drawn from volunteer counselor and user perceptions and experiences during the second year of operation of the NSAOH. Outcome data are presented from 731 session evaluations submitted by 94 volunteers and session evaluations from 4609 user sessions collected between June 1, 2008 and May 30, 2009. Evaluation includes ratings of usefulness, topics discussed, length of sessions, services provided, and session difficulties. The results indicate that the model is viable and useful, and the majority of volunteers and users are satisfied. Volunteer knowledge and skills are strongly associated with satisfaction with the hotline. Nevertheless, one-fifth of volunteers rate their session as not useful and users rate 8.2% of volunteers low in knowledge and skills. NSAOH is reaching many who have not previously sought services or did not resolve issues through other means. Findings suggest the importance of preparing volunteers in both crisis intervention and a wide variety of long-term issues related to sexual assault. Recommendations for program development, evaluation, and further research are presented. Copyright © 2010 Elsevier Ltd. All rights reserved.

This paper presents results from a pilot study of the synergies between the opportunity costs incurred by research participants, participant compensation, and program attendance in a family-based substance use and HIV preventive intervention for Hispanic adolescents in Miami-Dade County, Florida. To estimate parent/caretaker cost per session and cost for the duration of the intervention, we administered the Caretaker Drug Abuse Treatment Cost Analysis Program to a random sample of 34 families who participated in a recent clinical trial of Familias Unidas. The total opportunity cost per parent/caretaker was under $40 per group session, under $30 per family session, and just over $570 for the duration of the intervention. Participants were compensated between $40 and $50 per session and attended more than 79% of family and group sessions. Parents and caretakers incurred a cost of approximately $30-40 per intervention session for which they were adequately compensated. Attendance was very good overall for this group (>79%) and significantly higher than attendance in a comparable uncompensated study group from another recent Familias Unidas trial that targeted similar youth. Findings suggest that incentives should be considered important for future implementations of Familias Unidas and similar family-based interventions that target minority and low-SES populations.

Hypertension is a growing public health problem for U.S.-Mexico border Latinos, who commonly experience low levels of awareness, treatment, and control. We report on a process evaluation that assessed the delivery of Corazón por la Vida, a 9-week promotora de salud-led curriculum to help Latinos manage and reduce hypertension risks in two rural/frontier counties in the New Mexico border region. Ninety-six adults participated in the program, delivered in three waves and in three communities. We assessed program delivery and quality, adherence, exposure, and participant responsiveness. Participant outcome measures included self-reported eating and physical activities and assessment of community resources. Findings suggest that the program was fully delivered (99%) and that most participants (81.7%) were very satisfied with the educational sessions. The average participant attendance for educational sessions was 77.47%. We found significant differences in self-reported behavioral changes depending on the number of sessions completed: The higher the dose of sessions, the better the self-reported outcomes. These findings suggest that a promotora-led curriculum may be useful for promoting self-management of chronic disease in rural/frontier border Latino populations. Future evaluation should focus on training and implementation adaptations within evidence-based chronic disease programs for diverse Latino communities.

Postural control disorders are among the most frequent motor disorder symptoms associated with multiple sclerosis. This study aims to demonstrate the potential improvements in postural control among patients with multiple sclerosis who complete a telerehabilitation program that represents a feasible alternative to physical therapy for situations in which conventional treatment is not available. Fifty patients were recruited. Control group (n = 25) received physiotherapy treatment twice a week (40 min per session). Experimental group (n = 25) received monitored telerehabilitation treatment via videoconference using the Xbox 360® and Kinect console. Experimental group attended 40 sessions, four sessions per week (20 min per session).The treatment schedule lasted 10 weeks for both groups. A computerized dynamic posturography (Sensory Organization Test) was used to evaluate all patients at baseline and at the end of the treatment protocol. Results showed an improvement over general balance in both groups. Visual preference and the contribution of vestibular information yielded significant differences in the experimental group. Our results demonstrated that a telerehabilitation program based on a virtual reality system allows one to optimize the sensory information processing and integration systems necessary to maintain the balance and postural control of people with multiple sclerosis. We suggest that our virtual reality program enables anticipatory PC and response mechanisms and might serve as a successful therapeutic alternative in situations in which conventional therapy is not readily available.

This study investigated the efficacy of an Internet-based self-help program with minimal therapist contact via e-mail for Swedish university students with social phobia and public speaking fears. The main objective was to test if the Internet-based self-help program would be more effective if five live group exposure sessions were added. Thirty-eight students meeting the diagnostic and statistical manual of mental disorders, 4th edition criteria for social phobia were randomized into two different treatment groups: Internet delivered cognitive behavior therapy combined with five group exposure sessions (ICBT+ exp) or the Internet program alone (ICBT). Results were analyzed on an intention-to-treat basis. Both treatment groups showed significant improvement from pre- to post-test, and from pre-test to 1-year follow-up, on all measured dimensions (social anxiety, general anxiety, depression levels, and quality of life). For both the groups, the average within-group effect sizes for the primary social anxiety scales, expressed as Cohen's d, were comparable to those seen in traditionally administered cognitive behavioral therapy both at post-test and at 1- year follow-up. The results suggest that the Internet-based self-help program on its own is efficient in the treatment of university students with social phobia. Adding group exposure sessions did not improve the outcome significantly. Copyright 2008 Wiley-Liss, Inc.

Teaching and clinical educator competency: bringing two worlds together.

PubMed

Robinson, Cathy P

2009-01-01

More sessional clinical educators are being employed in educational institutions today than ever before. Also identified in the literature are issues affecting sessional clinical educators' ability to develop and maintain educator competency. Using the definition of educator competency by the National League for Nursing (NLN 2005a), explored in this paper are ways of increasing sessional clinical educator competency, such as orientation and mentorship programs to support student learning in clinical environments. Approaches in the form of theoretical models designed to evaluate clinical educator competency are examined. A new Sessional Clinical Educator Competency (SCEC) Framework is offered to provide direction for implementing strategies to develop and evaluate sessional clinical educator competency. Suggested is that the SCEC framework could be useful for educational administrators and sessional clinical educators to assess clinical educator competency.

A total of 36 alcohol dependents completed the study and questionnaires assessing their state. A single session of AAI reduced both subjective and physiological measures of state anxiety (A-State); and this program induced a significant reduction in the anxiety after an AAI program session with the dogs and cats involved in the intervention (p = 0.001). The Wilcoxon t-test showed that there were also significant differences in the "anxiety", "pleasantness", and "relaxation". scores for MCL-S.2 among the alcohol dependents, before and after AAI; a significantly decreased "anxiety" score (p = 0.006), and increased "pleasantness" (p = 0.002) and "relaxation" (p=0.012) scores for MCL-S.2 after AAI. The results of this study indicated that alcohol dependents who experienced a group AAI session-program exhibited significant improvements in their feeling; decreased anxiety, and increased pleasantness and relaxation.

We determined the efficacy and cost-effectiveness of adding an evidence-based Internet behavioral weight loss intervention alone or combined with optional group sessions to ShapeUp Rhode Island 2011 (SURI), a 3-month statewide wellness campaign. We randomized participants (n = 230; body mass index = 34.3 ±6.8 kg/m(2); 84% female) to the standard SURI program (S) or to 1 of 2 enhanced programs: SURI plus Internet behavioral program (SI) or SI plus optional group sessions (SIG). The primary outcome was weight loss at the end of the 3-month program. Weight losses differed among all 3 conditions (S: 1.1% ±0.9%; SI: 4.2% ±0.6%; SIG: 6.1% ±0.6%; Ps ≤ .04). Both SI and SIG increased the percentage of individuals who achieved a 5% weight loss (SI: 42%; SIG: 54%; S: 7%; Ps < .001). Cost per kilogram of weight loss was similar for S ($39) and SI ($35); both were lower than SIG ($114). Although weight losses were greatest at the end of SURI with optional group sessions, the addition of an Internet behavioral program was the most cost-effective method to enhance weight losses.

To describe the characteristics of clients who enrolled into of an opt-in, HIV, HBV & HCV Voluntary Counseling and Testing Program in Dobrogea Region, Romania (VCT) and to identify the utility of the pre-test counseling sessions in increasing subjective perception regarding transmission knowledge for the clients attending the VCT program. Cross sectional data collection, between August 2015 and September 2016. Sociodemographic and behavioral information were collected for the clients who enrolled at two Baylor centers. Counselors were trained regarding the delivery of standardized information during the session, to reduce variation. After the pre-test session clients evaluated the subjective level of knowledge (SK) increase regarding viral transmission. 3065 clients were screened at the two centers and completed the SK increase assessment after the pre-test session. About 9% of all persons tested had reactive results to any of the infections in the context of high exposure risks for 62% and low hepatitis B vaccination rates (8%). 78% of attendees perceived that their knowledge regarding HIV and viral hepatitis transmission increasing with more than 60% as the result of the pretest counselling; more information was gained about hepatitis transmission compared with HIV. Cumulative prevalence in Dobrogea community is high. The NGO-run VCT program is helping the healthcare system to efficiently screen for undiagnosed HIV and hepatitis cases. Pre-test counselling is directly contributing to increasing SK among attendees. Routine HIV and hepatitis integrated pre-test counseling should be considered as a good-practice even in settings where it is not compulsory by law. © 2018 British HIV Association.

This study examines the effects of a single session of Cognitive Bias Modification to induce positive Interpretative bias (CBM-I) using standard or explicit instructions and an analogue of computer-administered CBT (c-CBT) program on modifying cognitive biases and social anxiety. A sample of 76 volunteers with social anxiety attended a research site. At both pre- and post-test, participants completed two computer-administered tests of interpretative and attentional biases and a self-report measure of social anxiety. Participants in the training conditions completed a single session of either standard or explicit CBM-I positive training and a c-CBT program. Participants in the Control (no training) condition completed a CBM-I neutral task matched the active CBM-I intervention in format and duration but did not encourage positive disambiguation of socially ambiguous or threatening scenarios. Participants in both CBM-I programs (either standard or explicit instructions) and the c-CBT condition exhibited more positive interpretations of ambiguous social scenarios at post-test and one-week follow-up as compared to the Control condition. Moreover, the results showed that CBM-I and c-CBT, to some extent, changed negative attention biases in a positive direction. Furthermore, the results showed that both CBM-I training conditions and c-CBT reduced social anxiety symptoms at one-week follow-up. This study used a single session of CBM-I training, however multi-sessions intervention might result in more endurable positive CBM-I changes. A computerised single session of CBM-I and an analogue of c-CBT program reduced negative interpretative biases and social anxiety. Copyright © 2014 The Authors. Published by Elsevier Ltd..

This study was designed to measure the impact of a College of Nursing's (CON) Retention Program on students enrolled in a baccalaureate degree nursing program. Within the last ten years, undergraduate nurses increasingly have utilized the CON retention program. These students traditionally face a number of barriers to their academic endeavors. This study was designed to assess the effect of the CON program on the barriers to academic success of students who entered the CON in the Fall classes of 1991, 1992 and 1993. The sample size was 320 students. The control group consisted of 137 students who received no intervention and the experimental group was comprised of 183 students who attended intervention sessions with the Retention Coordinator in the CON. It was hypothesized that the most successful students during this period (1991-1993) were the most frequent attendees of the CON retention program intervention sessions. The alternative hypothesis was that those persons who did not attend the sessions, but were still highly persistent and successful, were enrollees who had entered with high entrance credentials as demonstrated by the transfer grade point averages (GPA). The results of this study indicated the need, use and value of this systematic approach to retention.

The purpose of this study was to examine the feasibility and acceptability of training peers to function as lifestyle coaches and to deliver a church-based lifestyle modification program. We recruited 6 African-American adults to participate in an 8-hour peer lifestyle coach (PLC) training program followed by a subsequent 2-hour booster session. The PLC training program addressed several key areas, including: (1) developing empowerment-based facilitation, active listening, and behavior change skills; (2) learning self-management strategies (eg, reading food labels, counting calories); (3) practicing session delivery; and (4) interpreting clinical lab results. Training evaluation was conducted retrospectively (immediately following the delivery of the diabetes prevention intervention rather than after the 8-hour training session) and measured program satisfaction and efficacy from the perspective of participants. Peer lifestyle coaches' confidence levels for performing core skills (eg, asking open-ended questions, 5-step behavioral goal-setting process) and advanced skills (eg, addressing resistance, discussing sensitive topics) were uniformly high. Similarly, PLCs were very satisfied with the length of training, balance between content and skills development, and preparation for leading group- and individual-based support activities. Findings suggest that it is feasible to customize a PLC training program that is acceptable to participants and that equips participants with the knowledge and skills to facilitate a church-based diabetes prevention intervention.

Improving self-esteem, dietary habits, and physical activity is essential for long-term success in childhood obesity prevention. The aim is to evaluate the effects of a healthy living promotion program, Healthy Kids-Houston, on BMI, dietary habits, self-esteem, and physical activity among minority children. The after-school program was implemented at community centers in low-income neighborhoods with close proximity to public schools. The program consisted of 3 6-week sessions. Each week, children attended 2 2-hour sessions. Each 2-hour session in the intervention included 90 minutes of structured physical activities and 30 minutes of nutrition and healthy habit lessons. The control group received typical enrichment programs. Outcomes were measured before the intervention and at the end of each 6-week session. We enrolled 877 children (age 10.2 ± 0.1 years (mean ± SE); body mass index z score: 1.49 ± 0.1; 52.0% boys; 72.6% Hispanic) in the program with 524 children received the intervention at 14 community centers and 353 children served as control at 10 community centers. The intervention led to no improvements in BMI z score (P = 0.78) and dietary habits (P = 0.46). Significant improvements (P ≤ 0.02) were detected in the amount of exercise that a child perceived to be required to offset a large meal and in several key self-esteem scores. No improvements were detected in physical activities (P ≥ 0.21). The improvement in some key self-esteem scores and nutrition knowledge may act as a mediator to motivate these children to adopt a healthier lifestyle in the future.

Incorporating sprint training with endurance training improves anaerobic capacity and 2,000-m Erg performance in trained oarsmen.

A 2,000-m time-trial performance, aerobic capacity, and anaerobic capacity were assessed in 16 trained oarsmen after sprint interval training (SIT) replaced a portion of an endurance-based training program (EBTSIT) vs. an endurance-based program alone (EBTAlone). The EBTSIT involved 10 SIT sessions over 4 weeks, in addition to 12 continuous exercise sessions, 2 anaerobic threshold exercise sessions, and 4 strength training sessions. The EBTAlone consisted of 20 continuous, 6 anaerobic threshold, 2 interval exercise sessions, and 8 strength training sessions. Time-trial performance (2,000-m erg performance) improved with EBTSIT (baseline = 414.6 ± 18.5, post = 410.6 ± 17.5 seconds; p < 0.001) but only approached significance in EBTAlone (baseline = 413.0 ± 27.7, post = 411.4 ± 27.9 seconds; p = 0.06). In a 60-second "all-out" anaerobic capacity test, peak power output (PPO) increased significantly with EBTSIT (PPO: EBTSIT: baseline = 566 ± 82, post = 623 ± 60 W; p = 0.02) but not with EBTAlone (EBTAlone: baseline = 603 ± 81, post = 591 ± 123 W; p = 0.59). Changes in average power output (APO) also approached significance (p = 0.07) (APO: EBTSIT: baseline = 508 ± 48, post = 530 ± 52 W; EBTAlone: baseline = 532 ± 55, post = 533 ± 68 W). Neither group experienced any change in aerobic capacity ((Equation is included in full-text article.)or ventilatory threshold; p ≥ 0.16). We conclude that replacing a portion of EBT with SIT can improve both 2,000-m erg performance and anaerobic capacity, while maintaining aerobic fitness in trained oarsmen. Incorporating SIT within endurance training programs may be useful during periods of low-volume training, to improve performance without sacrificing aerobic capacity.

To evaluate the long-term effects of an illicit drug use prevention program for adolescents that integrates life skills into the theory of planned behavior. We conducted a cluster-randomized trial in which 24 participating schools were randomized to either an intervention group (12 schools, n = 1,176 students) or a control group (12 schools, n = 915 students). Participants were grade 7 students. The intervention comprised a main intervention of 10 sessions and two booster interventions. Booster 1 (four sessions) and booster 2 (two sessions) were performed at 6 months and 12 months, respectively, after completion of the main intervention. Assessments were made at baseline, after the main intervention, and after each booster session using specific questionnaires for measuring participants' attitudes, subjective norms, perceived behavioral control, and life skills. Retention rates were 71.9% (845/1,176) in the intervention group and 90.7% (830/915) in the control group after the 12-month follow-up. A significantly lower proportion of intervention group participants reported illicit drug use after the first and second booster sessions compared with control group participants (.1% vs. 1.7% and .2% vs. 1.7%, respectively; both p < .05). Attitudes, subjective norms, perceived behavioral control, life skills, and behavioral intention scores of the intervention group were significantly higher than those of control group after the first and second booster sessions (all p < .001), suggesting that intervention group students tended to avoid drug use. A drug use prevention program integrating life skills into the theory of planned behavior may be effective for reducing illicit drug use and improving planned behavior-related constructs in adolescents.

Register, D

2001-01-01

This study evaluated the effects of music sessions using a curriculum designed to enhance the prereading and writing skills of 25 children aged 4 to 5 years who were enrolled in Early Intervention and Exceptional Student Education programs. This study was a replication of the work of Standley and Hughes (1997) and utilized a larger sample size (n = 50) in order to evaluate the efficacy of a music curriculum designed specifically to teach prereading and writing skills versus one that focuses on all developmental areas. Both the experimental (n = 25) and control (n = 25) groups received two 30-minute sessions each week for an entire school year for a minimum of 60 sessions per group. The differentiating factors between the two groups were the structure and components of the musical activities. The fall sessions for the experimental group were focused primarily on writing skills while the spring sessions taught reading/book concepts. Music sessions for the control group were based purely on the thematic material, as determined by the classroom teacher with purposeful exclusion of all preliteracy concepts. All participants were pretested at the beginning of the school year and posttested before the school year ended. Overall, results demonstrated that music sessions significantly enhanced both groups' abilities to learn prewriting and print concepts. However, the experimental group showed significantly higher results on the logo identification posttest and the word recognition test. Implications for curriculum design and academic and social applications of music in Early Intervention programs are discussed.

Background Anxiety disorders are common problems that result in enormous suffering and economic costs. The efficacy of Web-based self-help approaches for anxiety disorders has been demonstrated in a number of controlled trials. However, there is little data regarding the patterns of use and effectiveness of freely available Web-based interventions outside the context of controlled trials. Objective To examine the use and longitudinal effectiveness of a freely available, 12-session, Web-based, cognitive behavioral therapy (CBT) program for panic disorder and agoraphobia. Methods Cumulative anonymous data were analyzed from 99695 users of the Panic Center. Usage statistics for the website were examined and a longitudinal survey of self-reported symptoms for people who registered for the CBT program was conducted. The primary outcome measures were self-reported panic-attack frequency and severity at the beginning of each session (sessions 2-12). Results Between September 1, 2002 and February 1, 2004, there were 484695 visits and 1148097 page views from 99695 users to the Panic Center. In that same time period, 1161 users registered for the CBT program. There was an extremely high attrition rate with only 12 (1.03%) out of 1161 of registered users completing the 12-week program. However, even for those who remained in the program less than 12 weeks we found statistically significant reductions (P<.002) in self-reported panic attack frequency and severity, comparing 2 weeks of data against data after 3, 6, or 8 weeks. For example, the 152 users completing only 3 sessions of the program reduced their average number of attacks per day from 1.03 (week 2) to 0.63 (week 3) (P<.001). Conclusions Freely available Web-based self-help will likely be associated with high attrition. However, for the highly self-selected group who stayed in the program, significant improvements were observed. PMID:15829479

Study of the thermal internal boundary layer during sea-breeze events in the complex coastal area of Marseille

Calmet, Isabelle; Mestayer, Patrice

2016-02-01

A revisit of two sea-breeze episodes is presented, based on higher spatial resolution large eddy simulations (LES) of the lower atmosphere over the coastal area of Marseille and measurements obtained during the June 2001 experimental campaign UBL-ESCOMPTE. The focus is on the development of thermal internal boundary layers (TIBL) over a complex topography: the dynamic and thermal mechanisms that contribute to the TIBL growth and its further degeneration into a convective mixed layer, the respective influences of the coast shape, the large-scale flow above and the local low-level slope flows. The high-resolution LES permits exploring the potential temperature and turbulent kinetic energy fields in relation with the evolution of TIBL depth and heat fluxes along representative streamlines. Several theoretical TIBL depth models are further compared to the LES-deduced inversion height and other parameters, leading to a discussion of the relationships between the values of these parameters, the respective influences of the governing physical phenomena, and the TIBL behaviour. A threshold value of 0.35 is proposed for the friction velocity to convective velocity scale ratio u */ w * between the two regimes where the TIBL is either dominated by dynamical kinetic energy production or controlled by buoyancy.

Season-dependent size distribution of aerosols over the tropical coastal environment of south-west India

NASA Astrophysics Data System (ADS)

Aryasree, S.; Nair, Prabha R.

2018-01-01

This paper presents the results of a detailed study on the size characteristics of aerosols at the tropical coastal site Thiruvananthapuram based on the in-situ measurements of size resolved aerosol number density using an aerosol spectrometer, covering a period of 28 months from September 2011 to December 2013. The diurnal pattern of aerosol number density is characterized by day time low and a two-fold increase during nighttime and these changes are closely associated with the strong mesoscale features namely the sea breeze and land breeze prevailing at the site. Aerosol Number Size Distribution (NSD) depicts a multi-modal nature with two prominent modes, one ≤0.1 μm and other ∼1 μm. Two other less pronounced modes are also observed in the NSD, one ∼0.3-0.5 μm and other ∼5-8 μm. The NSDs also exhibited strong seasonal changes linked with the synoptic meteorological feature of this region namely the South Asian monsoon. The seasonal NSDs were parameterized and analyzed. In addition to this, the effects of meteorological parameters temperature, relative humidity, and wind speed and airflow patterns on aerosol number density as revealed by partial correlation analysis were found to be aerosol size dependent.

2016-04-01

The Qatar Environment and Energy Research Institute (QEERI) operates a network of air quality monitoring stations (AQMS) around the Doha metropolitan area and an ozonesonde station with regular weekly launches and occasional higher frequency launch experiments (HFLE). Six ozonesondes were launched at 0700 LT/0400 UTC and 1300 LT/1000 UTC over a three day period between 10-12 September, 2013. We present the analysis of the ozonesonde data coupled with regional chemical transport modeling over the same time period using WRF-Chem validated against both the ozonesonde and surface AQMS measurements. The HFLE and modeling show evidence of both subsidence and transboundary transport of ozone during the study period, coupled with a strong sea breeze circulation on the 11th of September resulting in elevated ozone concentrations throughout the boundary layer. The development of the sea breeze during the course of the day and influence of the early morning residual layer versus daytime production is quantified. The almost complete titration of ozone in the morning hours of 11 September, 2013 is attributed to local vehicular emissions of NOx and stable atmospheric conditions prevailing over the Doha area. The relative contribution of long range transport of ozone along the Arabian Gulf coast and local urban emissions are discussed.

Response of the Atmospheric Boundary Layer and Soil Layer to a High Altitude, Dense Aerosol Cover.

Garratt, J. R.; Pittock, A. B.; Walsh, K.

1990-01-01

The response of the atmospheric boundary layer to the appearance of a high-altitude smoke layer has been investigated in a mesoscale numerical model of the atmosphere. Emphasis is placed on the changes in mean boundary-layer structure and near-surface temperatures when smoke of absorption optical depth (AOD) in the, range 0 to 1 is introduced. Calculations have been made at 30°S, for different soil thermal properties and degrees of surface wetness, over a time period of several days during which major smoke-induced cooling occurs. The presence of smoke reduces the daytime mixed-layer depth and, for large enough values of AOD, results in a daytime surface inversion with large cooling confined to heights of less than a few hundred meters. Smoke-induced reductions in daytime soil and air temperatures of several degrees are typical, dependent critically upon soil wetness and smoke AOD. Locations near the coast experience reduced cooling whenever there is a significant onshore flow related to a sea breeze (this would also be the case with a large-scale onshore flow). The sea breeze itself disappears for large enough smoke AOD and, over sloping coastal terrain, a smoke-induced, offshore drainage flow may exist throughout the diurnal cycle.

Applying recycled iron-bearing waste materials (RIM) into iron ore sintering process is the general disposal approach worldwide, while its use is still a thorny problem. Results showed that adding RIM increased contents of hazardous elements (K, Na, Pb, Zn, and Cl) in sinter product, and also enhanced emission concentration of PM 2.5 in flue gas; increasing reaction temperature, and contents of CaO & coke breeze in raw mixtures improved hazardous elements removal. Based on these features, a novel method through granulating natural iron ores and RIM separately and distributing granulated RIM in bottom sintering layers was proposed for clean RIM cycle. When recycling 5% RIM, granulating RIM separately with higher contents of CaO and coke breeze removed hazardous elements effectively, the contents of which in sinter were reduced to comparable level of the case without RIM. Moreover, distributing RIM in bottom sintering layer reached intensive release of hazardous elements and PM 2.5 during sintering, which reduced the flue gas volume needing purification by about 2/3. Through activated carbon purification, about 60% of PM 2.5 comprised high contents of hazardous elements was removed. Novel technique eliminated the negative impact of RIM and has the prospect to reach clean recycle in sinter-making plants. Copyright © 2018. Published by Elsevier B.V.

The aim of this study was to investigate the effects of an explicit handwriting program introduced during the first grade of elementary school. Grade 1 children (N=23) with an age range of 6.1 to 7.4 yr. (15 girls, 8 boys) were administered an additional handwriting program of two weekly sessions of 45 min. over six weeks. Another group of 19 Grade 1 children (11 girls, 8 boys) received only the regular handwriting program of one weekly session. The Concise Assessment Scale for Children's Handwriting was administered to measure the changes in quality and speed of handwriting. The children given the explicit program showed better quality and speed of handwriting than did the control group. Their handwriting was more regular, with fewer ambiguous letters and fewer incorrect relative heights.

This study tested the effect of a short-term coordination program focused on improving the agility of school children ages 7 to 8 years. Healthy Japanese children were placed in an experimental group of 26 children (10 girls, 16 boys) and a control group of 20 children (9 girls, 11 boys). The experimental group participated in 10 coordination program sessions during recesses; each session was performed 1 to 3 times per week, for 26 days. No differences were observed between the groups in repeated side-step scores prior to the program, although an interaction was observed after the completion of the treatment. The short-term coordination program was effective in increasing the agility of elementary school children aged 7 to 8 years.

Despite high levels of participation in dementia education, general practitioners (GPs) and residential care facility (RCF) staff report perceived learning needs. Small group education, which is flexible, individualized, practical and case-based, is sought. We aimed to develop educational interventions for GPs and RCF staff tailored to meet their perceived educational needs. We used a consultative process to develop education programs. A flexible program for RCF staff was developed in 30-minute blocks, which could be combined in sessions of different lengths. The RCF program aimed to facilitate sustainable change by engaging local "Dementia Champions". For GPs, face-to-face and self-directed packages were developed. We collected participant feedback to evaluate the program. GPs and RCF staff were recruited as part of a larger intervention study. Sixteen of the 27 GPs who were offered the dementia education participated. Two of the 16 GPs participated in both learning packages. A total of 45 GP feedback responses were received from 16 GPs: 28 out of 45 GPs (62%) reported that the participants' learning needs were entirely met. Eighteen of 19 facilities offered the intervention participated and 326 RCF staff attended one or more of the 94 RCF education sessions. Feedback was collected from 93 sessions: 1013 out of 1067 RCF staff feedback responses (95%) reported that the session met the participants' learning needs. Qualitative feedback was also strongly positive. Participants perceived the education programs as meeting their needs. Despite explicit attempts to provide flexible delivery options, overall participation rates remained low.

To determine whether an early rehabilitation program was safe and feasible for patients during an acute exacerbation of chronic obstructive pulmonary disease (COPD). In this phase 1 randomized controlled trial, patients with an acute exacerbation of COPD admitted to the hospital were randomly allocated to a low-intensity exercise group, a moderate- to high-intensity exercise group, or a control group, who received routine physical therapy. In addition to routine physical therapy, patients in the exercise group had to participate in an exercise program. The program consisted of twice-daily aerobic and resistance exercise sessions. Primary outcomes were the number and classification of adverse events and program adherence. In 174 exercise sessions, there was 1 serious adverse event of arrhythmia in the low-intensity exercise group that resolved within 1 hour. There were 12 other minor adverse events involving 5 patients with no significant differences between groups. Patients completed an average of 80% of their scheduled sessions with no significant between-group differences. The exercise groups improved significantly in walking distance; however, no significant between-group differences were observed. There was preliminary evidence that it was safe and feasible to implement an exercise program for patients during an acute exacerbation of COPD. Additional studies with larger sample sizes are required to accurately evaluate program effectiveness.

Included in this publication is a collection of abstracts from the NASA-sponsored workshop, Polar Processes on Mars, which was held at the Sunnyvale Hilton Hotel, Sunnyvale, California, on 12 to 13 May 1988. Support for the workshop came from NASA's Planetary Geology and Geophysics program managed by Dr. Jospeh Boyce. The workshop is one of a series identified by MECA (an acronym for Mars: Evolution of its Climate and Atmosphere) as being worthy of focused research, but one for which it was not possible to hold during the project's lifetime. Consequently, it was held after the project ended. The MECA project was part of the Mars Data Analysis program. The workshop consisted of four sessions: The Polar Caps, Dynamics/Atmospheric Processes, Polar Geology, and Future Measurements. To put things into perspective, each of the first three sessions began with a review. All sessions were scheduled to allow ample time for discussion. A brief review of each session is provided.

This study sought to evaluate the effects of a Nintendo Wii Balance Board (NWBB) intervention on ankle spasticity and static standing balance in young people with spastic cerebral palsy (SCP). Ten children and adolescents (aged 72-204 months) with SCP participated in an exercise program with NWBB. The intervention lasted 6 weeks, 3 sessions per week, 25 minutes for each session. Ankle spasticity was assessed using the Modified Modified Ashworth Scale (MMAS), and static standing balance was quantified using posturographic measures (center-of-pressure [CoP] measures). Pre- and post-intervention measures were compared. Significant decreases of spasticity in the ankle plantar flexor muscles (p < 0.01). There was also a significant reduction in the CoP sway area (p = 0.04), CoP mediolateral velocity (p =0.03), and CoP anterior-posterior velocity (p = 0.03). A 6-session NWBB program reduces the spasticity at the ankle plantar flexors and improves the static standing balance in young people with SCP.

HIV risk among transgender women has been attributed to condomless sex with primary male partners. This study pilot tested a couples-focused HIV intervention program for transgender women and their primary male partners. We analyzed data from 56 transgender women and their male partners (n = 112 participants) who were randomized as a couple to one of two groups. Participants in the intervention group (27 couples) received 3 counseling sessions: 2 couples-focused sessions, which discussed relationship dynamics, communication, and HIV risk, and 1 individual-focused session on HIV prevention concerns. Participants in the control group (29 couples) received 1 session on general HIV prevention information delivered to both partners together. At 3-month follow-up, participants in the intervention reported lower odds of condomless sex with primary partners (OR 0.5, 95 % CI 0.3-1.0), reduced odds of engaging in sex with a casual partner (OR 0.3, 95 % CI 0.1-1.0), and reduction in the number of casual partners (B = -1.45, SE = 0.4) compared with the control group. Findings provide support for the feasibility and promise of a couples-focused HIV prevention intervention for transgender women and their primary male partners.

After-school programs may provide valuable opportunities for children to accumulate healthful physical activity (PA). This study assessed the PA of third-, fourth-, and fifth-grade children in the Keep It Moving! (KIM) after-school PA program, which was implemented in an ethnically diverse and low socioeconomic status school district in Colorado Springs, Colorado. The PA of KIM participating children (N = 116) at 4 elementary schools was objectively assessed using ActiGraph accelerometers and the System for Observing Fitness Instruction Time (SOFIT). Linear mixed-effects models or generalized linear mixed-effects models were used to compare time spent in sedentary (SED) behaviors, light PA (LPA), moderate PA (MPA), vigorous PA (VPA), and moderate-to-vigorous PA (MVPA) between genders and weight status classifications during KIM sessions. Children accumulated 7.6 minutes of SED time, 26.9 minutes of LPA, and 22.2 minutes of MVPA during KIM sessions. Boys accumulated less SED time (p < .05) and LPA (p = .04) than girls, but accumulated more MPA (p = .04), VPA (p = .03), and MVPA (p = .03). Overweight/obese children accumulated more LPA (p = .04) and less VPA (p < .05) than nonoverweight children. SOFIT data indicated that children spent a considerable proportion of KIM sessions being very active (12.4%), walking (36.0%), or standing (40.3%). The KIM program provides opportunities for disadvantaged children to accumulate substantial amounts of MVPA (>20 minutes per session) in an effort to meet current PA guidelines. © 2013, American School Health Association.

This study evaluated a positive parenting program to Brazilian mothers who used corporal punishment with their children. The intervention was conducted in four agencies serving vulnerable children, and at a home replica laboratory at the University. Mothers who admitted using corporal punishment were randomly assigned between experimental (n=20) and control group (n=20). The program consisted of 12 individual sessions using one unit from Projeto Parceria (Partnership Project), with specific guidelines and materials on positive parenting, followed by observational sessions of mother-child interaction with live coaching and a video feedback session in the lab. The study used an equivalent group experimental design with pre/post-test and follow-up, in randomized controlled trials. Measures involved: Initial Interview; Strengths and Difficulties Questionnaire (SDQ) - parent and child versions; Beck Depression Inventory (BDI); observational sessions with a protocol; and a Program Evaluation by participants. Analysis of mixed models for repeated measures revealed significant positive effects on the BDI and SDQ total scores, as well as less Conduct problems and Hyperactivity in SDQ measures from the experimental group mothers, comparing pre with post-test. Observational data also indicated significant improvement in positive interaction from the experimental group mothers at post-test, in comparison with controls. No significant results were found, however, in children's observational measures. Limitations of the study involved using a restricted sample, among others. Implications for future research are suggested. Copyright © 2017 Elsevier Ltd. All rights reserved.

2014-09-01

Most incarcerated women are mothers. Parenting programs may benefit women, children and families, yet effectively intervening in correctional settings is a challenge. An evidence-based parenting intervention (the Strengthening Families Program) was tailored and implemented with women in a jail setting. Goals were to assess mothers' needs and interests regarding parenting while they were incarcerated, adapt the program to address those needs, and establish intervention delivery and evaluation methods in collaboration with a community-based agency. Women reported wanting to know more about effective communication; how children manage stress; finances; drug and alcohol use; self-care; and stress reduction. They reported high program satisfaction and reported reduced endorsement of corporal punishment after the intervention. Barriers to implementation included unpredictable attendance from session to session due to changing release dates, transfer to other facilities, and jail policies (e.g., lock-down; commissary hours). Implications for sustainable implementation of parenting programs in jail settings are discussed.

This pilot study compares the effectiveness of home- and community-based physical activity interventions that target mothers and daughters to increase physical activity and improve health-related fitness. Mothers (45.18 +/- 7.49 yr) and daughters (15.41 +/- 1.33 yr) were randomly assigned to a community-based (CB) (N = 20 participants) or home-based (HB) (N = 14 participants) program. CB participants attended three instructor-led sessions per week for 12 wk. HB participants were asked to participate in 3 sessions per week for 12 wk in a program similar to the CB program. The main difference between the programs was that CB activities were completed at a fitness facility within a university and HB activities were completed in or near the home. Before and after the intervention, changes in health-related fitness and physical activity were assessed. A series of 2 (group assignment) x 2 (time) ANOVAs were conducted to assess changes separately for mothers and daughters. CB participants attended 77% of the sessions, and none of the pairs dropped out. HB participants completed 70% of the recommended sessions, and three pairs dropped out. Mothers and daughters in both groups significantly increased their participation in aerobic, muscular strength, and flexibility activities (P = 0.02 to 0.000). Daughters in both groups significantly improved their muscular endurance (sit-ups,P = 0.000). Mothers in both groups improved their muscular strength (push-ups, P = 0.003), muscular endurance (sit-ups, P = 0.000), flexibility (sit-and-reach, P = 0.008), and aerobic capacity (1-mile walk, P = 0.002). Positive changes in diastolic blood pressure also occurred (P = 0.008). Mothers and daughters responded positively to CB and HB physical activity programs. Home-based physical activity programming is a cost-effective means to increase physical activity and improve health-related fitness in these groups.

The loss of a dark night sky as a natural resource is a growing concern. It impacts not only astronomical research, but also health, ecology, safety, economics and energy conservation. Because of its relevance, "Dark Skies” is a theme of the US Node for the International Year of Astronomy (IYA). Its goal is to raise public awareness of the impact of artificial lighting on local environments by getting people involved in a variety of dark skies-related programs. To reach this goal, the ASP session will immerse participants in hands-on, minds-on activities, events and resources on dark skies awareness. These include a planetarium show on DVD, podcasting, social networking, a digital photography contest, The Great Switch Out, Earth Hour, National Dark Skies Week, a traveling exhibit, a 6-minute video tutorial, Dark Skies Teaching Sites, Astronomy Nights in the (National) Parks, Sidewalk Astronomy Nights, and unaided-eye and digital-meter star counting programs like GLOBE at Night. The ASP "Dark Skies” session is offered to provide IYA dark skies-related programs to a variety of attendees. Participants include professional or amateur astronomers, education and public outreach professionals, science center/museum/planetarium staff and educators who want to lead activities involving dark skies awareness in conjunction with IYA. During the session, each participant will be given a package of educational materials on the various dark skies programs. We will provide the "know-how” and the means for session attendees to become community leaders in promoting these dark skies programs as public events at their home institutions during IYA. Participants will be able to jump-start their education programs through the use of well-developed instructional materials and kits sent later if they commit to leading IYA dark skies activities.

2009-12-01

The purpose of the present trial was to develop and evaluate an educational program for promotion of healthy nutrition and physical activity by health volunteers. The educational program consisted of the following four phases: preliminary self-learning by mail (3 weeks), basic learning (3 sessions of 3 hours), practice of planned activities (2 months), and a report session (1 session of 3 hours). Beginner volunteers (n=18, mean age 63.3 +/- 6.4) were recruited from two volunteer health organizations in Kurume city. They then participated in a program that taught basic health knowledge regarding nutrition and physical activity, how to plan effective support activities, and methods for self-evaluation. In the preliminary self-learning phase, an assessment sheet, health information, and homework (goal setting, etc.) were delivered to the volunteers by mail. In the basic learning phase, volunteers attended a 3 day seminar on essential principles for behavioral change and assessment methods for volunteer activity. In addition, effective support activities were planned through group discussion. After a 2-month practice of support activities, each group reported and discussed the results of their activity in a 3-hour report session. Main outcome measures were health knowledge (15 items, 0-1 points), self-efficacy for life style support (5 items, 0-100%), and evaluation of the educational program (9 items, 1-5 points). All measures were self-administered. Significant increases in rate of true answers for health knowledge were observed during the preliminary self-learning and before basic learning phases (54.8% --> 67.1%, P < 0.05), and before and after basic learning phases (67.1% --> 87.6%, P < 0.05). Self-efficacy for life style support were significantly higher after the report session than before the preliminary self-learning phase (35.1% --> 53.1%, P < 0.05). In the two-month practice, all groups received feedback through questionnaires completed by participants who took part in their planned activity. The mean scores for the overall evaluation of the program, the effectiveness of the course materials and group-work, the staff, and the course contents were all higher than 4.0 points. These findings indicate that this program is structured effectively and is appropriate for educating beginner health volunteers regarding promotion of healthy nutrition and physical activity.

The present study aimed to investigate a simple education program that is effective for sleep improvement among medical students who will be medical doctors in the future. The education program applied in the present study was developed for sleep improvement based on behavioral science and changes in knowledge and sleeping habits were observed. Subjects were 6th-year medical students of 2002 and 2003. Students of 2002 attended a program including a 90-minute lecture and a 2-week practice learning session, and students of 2003 attended only the lecture. In the lecture, behavior therapy for chronic insomnia was explained using a booklet. In the practice learning session, students set a target behavior for improvement and conducted self-monitoring of their sleep and the targeted behavior. Changes in knowledge about sleep, attitude toward the therapy, sleep, and sleep-related habits were observed and compared between the 2 groups of subjects immediately and 2-weeks after the lecture. It was found that after both programs subjects had more knowledge about sleep than before. In the program including practice learning session, subjects' attitude for managing patients changed from before the lecture to after the lecture, and after the practice learning session. It was found that more than half of the students thought that they could provide sleep guidance based on the behavior therapy. Regarding the subjects' sleep, significant improvements were observed for "having nightmares upon falling asleep," "sleepiness during daytime," "sense of getting a sound sleep," and "mood upon waking up." Regarding sleep-related habits, significant improvements were observed for "taking a nap," "dozing off," and "eating breakfast." On the other hand, only the lecture subjects improved irregularity of bedtime and sleeping time. Although an increase in knowledge and improvement of sleep were observed among students who attended only the lecture, a further increase in knowledge and improvement of sleeping habits were observed among students who also attended the practice learning session. The results described herein suggest developing and providing a simple and convenient education program for sleep improvement was effective for increasing students' knowledge about sleep, developing improved coping methods regarding sleep, and improving sleep. It is also suggested that behavioral scientific instructive methods, including practice learning, are effective for medical education.

SpaceTech is a postgraduate program geared primarily for mid-career space professionals seeking to gain or improve their expertise in space systems engineering and in business engineering. SpaceTech provides a lifelong impact on its participants by broadening their capabilities, encouraging systematic "end-to-end" thinking and preparing them for any technical or business-related engineering challenges they may encounter. This flexible 1-year program offers high competency gain and increased business skills. It is held in attractive locations in a flexible, multi-cultural environment. SpaceTech is a highly effective master's program certified by the esteemed Technical University of Delft (TUD), Netherlands. SpaceTech provides expert instructors who place no barriers between themselves and participants. The program combines innovative and flexible new approaches with time-tested methods to give participants the skills required for future missions and new business, while allowing participants to meet their work commitments at the same time as they study for their master's degree. The SpaceTech program is conducted in separate sessions, generally each of 2-week duration, separated by periods of some 6-8 weeks, during which time participants may return to their normal jobs. It also includes introductory online course material that the participants can study at their leisure. The first session is held at the TUD, with subsequent sessions held at strategic space agency locations. By participating at two or more of these sessions, attendees can earn certificates of satisfactory completion from TU Delft. By participating in all of the sessions, as well as taking part in the companion Central Case Project (CCP), participants earn an accredited and highly respected master's degree in Space Systems Engineering from the TUD. Seven distinct SpaceTech modules are provided during these sessions: Space Mission Analysis and Design, Systems Engineering, Business Engineering, Interpersonal Skills, Telecommunications, Earth Observation and Navigation. A group CCP, a major asset of this unique program, is a focused project, aimed at the formation of a credible virtual commercial space-related business. Participants exercise space systems engineering fundamentals as well as marketing and business engineering tools, with the goal of creating a financially viable business opportunity. They then present the result, in the form of an unsolicited proposal to potential investors, as well as a varied group of engineers, managers and executives from the space community. During the CCP, participants learn the ties between mission and system design and the potential return to investors. They develop an instinct for the technical concepts and which of the parameters to adjust to make their newly conceived business more effective and profitable.

Objectives. We determined the efficacy and cost-effectiveness of adding an evidence-based Internet behavioral weight loss intervention alone or combined with optional group sessions to ShapeUp Rhode Island 2011 (SURI), a 3-month statewide wellness campaign. Methods. We randomized participants (n = 230; body mass index = 34.3 ±6.8 kg/m2; 84% female) to the standard SURI program (S) or to 1 of 2 enhanced programs: SURI plus Internet behavioral program (SI) or SI plus optional group sessions (SIG). The primary outcome was weight loss at the end of the 3-month program. Results. Weight losses differed among all 3 conditions (S: 1.1% ±0.9%; SI: 4.2% ±0.6%; SIG: 6.1% ±0.6%; Ps ≤ .04). Both SI and SIG increased the percentage of individuals who achieved a 5% weight loss (SI: 42%; SIG: 54%; S: 7%; Ps < .001). Cost per kilogram of weight loss was similar for S ($39) and SI ($35); both were lower than SIG ($114). Conclusions. Although weight losses were greatest at the end of SURI with optional group sessions, the addition of an Internet behavioral program was the most cost-effective method to enhance weight losses.

To determine the effects of training sessions, involving high-resistance, low-repetition bench press exercise, on strength recovery patterns, as a function of gender and training background. The subjects were 12 athletes (6 males and 6 females) and age-matched college students of both genders (4 males and 4 females). The subjects completed a 3-wk resistance training program involving a bench press exercise, 3 d/wk, to become familiar with the testing procedure. After the completion of the resistance training program, the subjects, on three consecutive weeks, participated in two testing sessions per week, baseline session and recovery session. During the testing sessions, subjects performed five sets of the bench press exercise at 50% to 100% of perceived five repetition maximum (5-RM). Following the weekly baseline sessions, subjects rested during a 4-, 24-, or 48-h recovery period. Strength measurements were estimates of one repetition maximum (1-RM), using equivalent percentages for the number of repetitions completed by the subject at the perceived 5-RM effort of the bench press exercise. The full-factorial ANOVA model revealed a Gender by Recovery Period by Testing Session interaction effect, F(2, 32) = 10.65; P < .05. Among male subjects, decreases in estimated 1-RM were detected at the 4- and 24-h recovery times. There were no differences in muscle strength among the female subjects, regardless of recovery time. For bench press exercises, using different recovery times of 48 h for males and 4 h for females may optimize strength development as a function of gender.

The study examined participant's experience and individual characteristics during a 7-week computer activity program for persons with dementia. The descriptive study with mixed methods design collected 612 observational logs of computer sessions from 27 study participants, including individual interviews before and after the program. Quantitative data analysis included descriptive statistics, correlational coefficients, t-test, and chi-square. Content analysis was used to analyze qualitative data. Each participant averaged 23 sessions and 591min for 7 weeks. Computer activities included slide shows with music, games, internet use, and emailing. On average, they had a high score of intensity in engagement per session. Women attended significantly more sessions than men. Higher education level was associated with a higher number of different activities used per session and more time spent on online games. Older participants felt more tired. Feeling tired was significantly correlated with a higher number of weeks with only one session attendance per week. More anticholinergic medications taken by participants were significantly associated with a higher percentage of sessions with disengagement. The findings were significant at p < .05. Qualitative content analysis indicated tailoring computer activities appropriate to individual's needs and functioning is critical. All participants needed technical assistance. A framework for tailoring computer activities may provide guidance on developing and maintaining treatment fidelity of tailored computer activity interventions among persons with dementia. Practice guidelines and education protocols may assist caregivers and service providers to integrate computer activities into homes and aging services settings. © The Author 2015.

This paper reports on the effects on parenting and on children's mental health problems and competencies from a randomized trial of a parenting program for divorced and separated fathers. The program, New Beginnings Program-Dads (NBP-Dads), includes ten group sessions (plus two phone sessions) which promote parenting skills to increase positive interactions with children, improve father-child communication, use of effective discipline strategies, and skills to protect children from exposure to interparental conflict. The program was adapted from the New Beginnings Program, which has been tested in two randomized trials with divorced mothers and shown to strengthen mothers' parenting and improve long-term outcomes for children (Wolchik et al. 2007). Fathers were randomly assigned to receive either NBP-Dads or a 2-session active comparison program. The sample consisted of 384 fathers (201 NBP-Dads, 183 comparisons) and their children. Assessments using father, youth, and teacher reports were conducted at pretest, posttest, and 10-month follow-up. Results indicated positive effects of NBP-Dads to strengthen parenting as reported by fathers and youth at posttest and 10-month follow-up. Program effects to reduce child internalizing problems and increase social competence were found at 10 months. Many of the program effects were moderated by baseline level of the variable, child age, gender, and father ethnicity. This is the first randomized trial to find significant effects to strengthen father parenting following divorce. In view of recent changes in family courts to allot fathers increasing amounts of parenting time following divorce, the results have significant implications for improving outcomes for children from divorced families.

Mean age - 40±8,56 (22-65) year; 254 (51.4%) were in treatment for 1-3 year. Evaluation was carried out on the base of structured self-questionnaire that covers demographics, drug use history, general drug use trends, psychotherapeutic sessions' acceptance and open label question regarding treatment challenges and satisfaction. 305 (60.3%) attended individual and 57 (11.3%) group psychotherapy sessions with 50.79% attending once/month or rare. The main reason given for therapy non-attendance - no needs for it (29.48%); the main drugs before admission - heroin (80.04%), buprenorphine (53.49%); Main drugs used in Georgia nowadays - desomorphine ("crocodile"), alcohol and marihuana. Commonly used drugs by program patients (136 positive answers) - alcohol-13.62%, marihuana-10.39%, pregabalin - 8.17%, opioids- 6.62% (mostly-"crocodile"), home-made stimulants-6.23%, sedatives -5.45%. 55.4% are extremely satisfied with treatment, 82.4% - with program staff. Patients' main wishes- free of charge programs (46.4%) and provide take-home doses (22.07%). Methadone and Suboxone ST are being well accepted in Georgia and appear to be reducing illegal opioid use. However, the psychotherapeutic sessions' attendance is very low.

In this Special Session we will highlight the important role of Minority Serving Institutions in preparing future minority astronomers. Minority Serving Institutions include Historically Black Colleges and Universities (HBCUs), Hispanic Serving Institutions (HSIs), and Tribal Colleges and Universities (TCUs). We will also stress the role that REU (Research Experiences for Undergraduates) programs can have in enhancing diversity in astronomy. The session will feature a panel of invited speakers from Minority Serving Institutions and REU programs who will present viewpoints, strategies, and discussion on processes that encourage and mentor individuals who elect to pursue science-related careers including astronomy and astrophysics. Specific objectives for the Session include: Report to the AAS membership on the important role played by Minority Serving Institutions, where these institutions are, the populations they serve; Introduce the AAS membership to representatives from various Minority Serving Institutions, including an HBCU, an HSI, a TCU, and a community college, and to representatives from REU programs; Provide an opportunity for representatives from these institutions to describe their role in preparing minority undergraduates in the sciences, how their programs bridge to PhD-granting programs in astronomy, and ways they suggest for the AAS to help enhance these bridges; Provide an opportunity for AAS members to dialogue with these representatives, hopefully resulting in specific ``action items" that will serve to strengthen partnerships with Minority Serving Institutions.

Studies indicate that adolescent-onset drug users experience a greater likelihood of dependence that continues into adulthood. The importance of early intervention was evident in treating adolescents before their substance use progressed. We examined the effectiveness of an intervention program that prevents students who experiment with drugs from reusing them. The study was based on 10 out of 18 invited schools that were randomly assigned to either the intervention group (5 schools, n = 43) or the comparison group (5 schools, n = 41). The intervention group received an E-course program that comprised a main intervention course (12 sessions) and a booster course (2 sessions). By reducing the burden of teaching content during the 14 sessions, the in-class counselor had opportunities for face-to-face discussions with students on their ambivalence toward quitting illegal drugs. The comparison group received the conventional didactic drug prevention course (2 sessions). Outcomes in terms of stress management, refusal skills, pros of drug use, cons of drug use, and drug use resistance self-efficacy were measured via structured questionnaires conducted thrice: at baseline, after the main intervention sessions, and after the booster sessions. A linear mixed model (LMM) was employed to investigate the effects of time and groups on the outcome variables with group, time, and group × time as fixed effects. Subjects and schools were selected as random effects in order to consider both within-subject and within-school correlations. There was a significant group × time interaction with regard to stress management, refusal skills, pros of drug use, and drug use resistance self-efficacy, excluding cons of drug use. The intervention group displayed better stress management compared to the comparison group after the booster intervention. Similar between-group differences were identified in that the intervention group displayed better refusal skills and drug use resistance self-efficacy compared to that of the comparison group. The intervention group favored using drugs less (a decrease in the pros of drug use score) compared to the comparison group after the booster intervention. Our program provided an example of the results of early intervention among students who experiment with illegal drugs.

Mahadevan, S; Muralidhar, Kanchi; Shetty, Devi

2012-11-01

We have used a telemedicine facility to conduct academic teaching/training sessions. The objective of this study was to examine the feasibility, advantages, and disadvantages of this method of e-learning sessions. The teaching/learning sessions were organized twice a week between the two teaching hospitals. The success of each academic session was analyzed in terms of satisfaction of the participating candidates, infrastructure difficulties (if any), and the overall outcome of the program. In total, 293 academic sessions were held from 2008 to 2010. Each session's presentation was 45 min long and was made using Microsoft(®) (Redmond, WA) PowerPoint. We have found that telemedicine proved to be effective in establishing communication not only between the patient and the physician, but also between the teacher and the student. Several candidates benefited from the application of this technology. Candidates expressed satisfaction and were content with the teaching methods adapted.

PubMed

1995-01-01

The great deal of documentation which was prepared for the recent TSS/CST Population IEC (information, education, and communication) meeting from research, field experiments, and action projects will be useful to TSS/CST advisors and individual countries undertaking IEC and population education work. This article summarizes the 12 sessions held during the open forum. To illustrate some of the latest trends in population and health communication, the "enter-educate" approach and use of the interactive computer software called SCOPE (Strategic Communication Planning and Evaluation) were discussed. Next, ways in which to apply research effectively in IEC and population education were considered. Examples were provided of 1) a workshop methodology used to help a multidisciplinary group design a problem-solving communication strategy in Malaysia and Dominica; 2) the counseling training evaluation technique based on the GATHER (greet, ask, tell, help, explain, and return for follow-up) model; and 3) four types of evaluation of population education in schools. The third session was concerned with the program approach used in IEC and population education. Session 4 dealt with the implication of UNFPA support to family planning (FP) IEC. Counseling skills training and interpersonal communication were next on the agenda, followed by a consideration of how knowledge and policies are applied in the area of youth. The seventh session concentrated on ways to involve men in FP and reproductive health and included a discussion of a case study on the attitude and behavior of men with regard to FP which had IEC implications. The next session described the need to reconceptualize population education and what such a reconceptualization would entail. Session 9 was devoted to a consideration of gender issues and the education of girls. The tenth session covered the use of participatory approaches and community involvement in population communication programs. Innovative methodologies for school-based population education were described next, and the last session was concerned with new information technologies such as navigating the Internet and using new software for establishing databases.

Physical activity (PA) has documented health benefits, but older Latinos are less likely to engage in leisure time PA than older non-Latino whites. Dance holds promise as a culturally appropriate form of PA that challenges individuals physically and cognitively. This paper describes a randomized controlled trial that will test the efficacy of BAILAMOS©, a 4-month Latin dance program followed by a 4-month maintenance program, for improving lifestyle PA and health outcomes. Older adults (n = 332), aged 55+, Latino/Hispanic, Spanish speaking, with low PA levels, and at risk for disability will be randomized to one of two programs, a dance program or health education control group. BAILAMOS© is a 4-month program that meets two times per week for one hour per session. Dance sessions focus on instruction, including four styles of dance, and couples dancing. Bi-monthly “Fiestas de Baile” (dance parties) are also included, in which participants dance and practice what they have learned.. Monthly 1-hour discussion sessions utilize a Social Cognitive framework and focus on knowledge, social support, and self-efficacy to increase lifestyle PA. The health education control group will meet one time per week for two hours per session. Primary outcomes including PA changes and secondary outcomes including self-efficacy, physical function, cognitive function, and disability will be assessed at baseline, 4, and 8 months. It is hypothesized that PA, self-efficacy, physical function, cognitive function, and functional limitations and disability scores will be significantly better in the BAILAMOS© group at 4 and 8 months compared to the control group.

Although the benefits of comprehensive pulmonary rehabilitation have been demonstrated in patients with COPD, the effects of exercise sessions within self-management programs remain unclear. We hypothesized that 8 supervised exercise sessions incorporated in a 1-month self-management education program in COPD patients would be effective to improve health outcomes and to reduce direct medical costs after one year, compared to usual care. In this randomized controlled trial, 38 moderate-to-severe COPD patients were assigned either to an intervention group or to a usual care group. The hospital-based intervention program provided a combination of 8 sessions of supervised exercise with 8 self-management education sessions over a 1-month period. The primary end-point was the 6-min walking distance (6MWD), with secondary outcomes being health-related quality of life (HRQoL)--using the St. George's Respiratory Questionnaire (SGRQ) and Nottingham Health Profile (NHP), maximal exercise capacity and healthcare utilization. Data were collected before and one year after the program. After 12 months, we found statistically significant between-group differences in favor of the intervention group in 6MWD (+50.5 m (95%CI, 2 to 99), in two domains of NHP (energy, -19.8 (-38 to -1); emotional reaction, -10.4 (-20 to 0)); in SGRQ-symptoms (-14.0 (-23 to -5)), and in cost of COPD medication (-480.7 € (CI, -891 to -70) per patient per year). The present hospital-based intervention combining supervised exercise with self-management education provides significant improvements in patient's exercise tolerance and HRQoL, and significant decrease of COPD medication costs, compared to usual care.

Objective To evaluate self-esteem and self-image of respiratory diseases patients in a Pulmonary Rehabilitation Program, who participated in socialization and physical fitness activities, and of patients who participated only in physical fitness sessions. Methods A descriptive cross-sectional exploratory study. Out of a total of 60 patients analyzed, all enrolled in the Pulmonary Rehabilitation Program, 42 participated in at least one of the proposed activities, 10 did not participate in any activity and 8 were excluded (7 were discharged and 1 died). Results When the two groups were compared, despite the fact that both demonstrated low self-esteem and self-image, the difference between them was relevant (p<0.05) regarding self-esteem, indicating that those who participated in the proposed socialization activities had better self-esteem than the individuals who only did the physical fitness sessions. Regarding self-image, the difference between the groups was not relevant (p>0.05). Conclusion The Pulmonary Rehabilitation Program patients evaluated presented low self-esteem and self-image; however, those carrying out some socialization activity proposed had better self-esteem as compared to the individuals who did only the physical fitness sessions.

Purpose Even though physical education (PE) is an evidence-based strategy for providing and promoting physical activity, alternative programs such as Junior Reserve Officer Training Corps (JROTC) are commonly substituted for PE in many states. The purpose of this study was to compare student physical activity and lesson contexts during high school PE and JROTC sessions. Method SOFIT (System for Observing Fitness Instruction Time) was used to assess PE and JROTC sessions (N=38 each) in 4 high schools that provided both programs. Data were analyzed using t-tests, negative binomial regression, and logistic regression. Results Students engaged in significantly more moderate to vigorous physical activity during PE than JROTC sessions and they were significantly less sedentary. Significant differences between the two program types were also found among lesson contexts. Conclusions PE and JROTC provide substantially different content and contexts and students in them engage in substantially different amounts of moderate to vigorous physical activity. Students in JROTC, and perhaps other alternative programs, are less likely to accrue health-supporting physical activity and engage in fewer opportunities to be physically fit and motorically skilled. Policies and practices for providing substitutions for PE should be carefully examined. PMID:25141093

Purpose Fatigue is an important problem in children receiving intensive chemotherapy and hematopoietic stem cell transplantation (HSCT). Exercise may be an effective intervention for fatigue. Individualized yoga represents an ideal intervention because it can be tailored according to an individual child's needs. Little is known about how to structure a standardized yoga program for intensivelytreated children. Therefore, this study describes the development of a yoga program and an approach to monitoring sessions suitable for hospitalized children receiving intensive chemotherapy or HSCT. Methods The yoga program was designed to increase mobility in hospitalized children and to provide children with relaxation techniques that could be used independently in a variety of environments. The program was founded on 4 key tenets: safety, adaptability, environmental flexibility, and appeal to children. We also developed quality and consistency assurance procedures. Results A menu format with a fixed structure was selected for the yoga program. Each yoga session contained up to 6 sections: breathing exercises, warmup exercises, yoga poses, balancing poses, cool-down poses, and final relaxation. Yoga instructors selected specific yoga poses for each session from a predetermined list organized by intensity level (low, moderate, or high). Monitoring procedures were developed using videotaping and multirater adjudication. Conclusion We created a standardized yoga program and an approach to monitoring that are now ready for incorporation in clinical trials. Future work should include the adaptation of the program to different pediatric populations and clinical settings. © The Author(s) 2016.

Formative and summative evaluation efforts for the Teacher Enhancement Institute conducted at the NASA Langley Research Center, summer 1994

1994-01-01

The Teacher Enhancement Institute (TEI) at NASA Langley Research Center was developed in response to Executive Order 12821 which mandates national laboratories to 'assist in the mathematics and science education of our Nation's students, teachers, parents, and the public by establishing programs at their agency to provide for training elementary and secondary school teachers to improve their knowledge of mathematics and science. Such programs, to the maximum extent possible, shall involve partnerships with universities, state and local elementary and secondary school authorities, corporations and community based organizations'. The faculty worked closely with one another and the invited speakers to insure that the sessions supported the objectives. Speakers were informed of the objectives and given guidance concerning form and function for the session. Faculty members monitored sessions to assist speakers and to provide a quality control function. Faculty provided feedback to speakers concerning general objective accomplishment. Participant comments were also provided when applicable. Post TEI surveys asked for specific comments about each TEI session. During the second of the two, two week institutes, daily critiques were provided to the participants for their reflection. This seemed to provide much improved feedback to speakers and faculty because the sessions were fresh in each participant's mind. Between sessions one and two, some changes were made to the program as a result of the formative evaluation process. Those changes, though, were minor in nature and comprised what may be called 'fine tuning' a well conceived and implemented program. After the objectives were written, an assessment instrument was developed to test the accomplishment of the objectives. This instrument was actually two surveys, one given before the TEI and one given after the TEI. In using such a series, it was expected that changes in the participants induced by attendance at TEI may be discovered. Because the institute was limited in time and depth of exposure, attitudinal changes (self-assessment of ability and confidence) were chosen to be surveyed. On the pre-survey, seven general categories of questions were asked. The post-survey repeated three of these categories, providing a pre and post evaluation of the same questions and added a fourth category which asked the participant to self-assess objective accomplishment. The assessment process for TEI was valuable when one looks at the final accomplishments of the TEI. A number of aspects stand out: (1) formative evaluation during project development allowed the goals and objectives to guide the development of the institute; (2) formative evaluation provided positive guidance to presenters in developing and implementing their session; (3) formative evaluation helped presenters to improve or focus their sessions; (4) summative evaluation provided managers a way to gauge the success of the institute; (5) summative evaluation provided a benchmark for future programs to be measured against.

Causal-comparative study analyzing student success in hybrid anatomy and physiology courses

NASA Astrophysics Data System (ADS)

Levy, Jacqueline Anita

In the biological sciences, higher student success levels are achieved in traditionally formatted, face-to-face coursework than in hybrid courses. The methodologies used to combine hybrid and in-person elements to the course need to be applied to the biological sciences to emulate the success seen in the traditional courses since the number of hybrid course offerings at community colleges are rapidly increasing. Research has delineated that creating online collaborative communities and increasing student engagement all function to increase student successful outcomes. This causal-comparative study was conducted using student data from four sections of hybrid, introductory anatomy and physiology courses over the 2011 and 2012 calendar years. The study included two sources of data: unit exam scores and student surveys. Analysis of the unit exam scores determined that there were statistically significant differences in student success and achievement by the implementation of the following web-enhanced technologies: a) discussion boards, b) Breeze, and c) Wiki tools. In the scope of this study, student success and achievement was defined as a student earning a C (70%) or higher at the completion of the course. There were a total of 29 surveys conducted per each unit during the 2012 semesters that related to the web-enhanced technologies implemented into the course: Discussion boards, BreezeRTM, and Wiki tools. Demographic data was also compiled on all of the students enrolled in the classes during this study to demonstrate that there is no specified niche or trend seen in the students enrolling for this particular course. Unit 1 was used as a baseline to compare the students from the two years. It was determined that the students were not significantly different in aptitude levels at the beginning of the courses based on their Unit 1 exam scores. Inferential statistical analysis was done to examine student success and achievement using the following tools: t-test of independent means of the variables, mean, standard deviation, and magnitude of effect. The findings of this study indicate that the web-enhanced technology Wiki tools provided the largest increase in student success and achievement in the hybrid, introductory anatomy and physiology course. Descriptive analysis of the surveys revealed that more than a third of each class felt that the implemented web-enhanced technology functioned to increase collaboration amongst the students and helped to emulate a traditional, face-to-face formatted course. The study included four recommendations for practice and nine recommendations for further research. A couple of recommendations for practice included using a single web-enhanced technology for the duration of the semester and having instructors and students complete tutorial sessions for the chosen technology being implemented. Examples of recommendations for research include replicating this study at other institutions and comparing face-to-face, traditional classes to hybrid courses within the same STEM discipline.

This study investigated the effect of a 12-session, implicit perceptual-motor training program on decision-making skills and visual search behavior of highly skilled junior female karate fighters (M age = 15.7 years, SD = 1.2). Eighteen participants were required to make (physical or verbal) reaction decisions to various attacks within different fighting scenarios. Fighters' performance and eye movements were assessed before and after the intervention, and during acquisition through the use of video-based and on-mat decision-making tests. The video-based test revealed that following training, only the implicit perceptual-motor group (n = 6) improved their decision-making accuracy significantly compared to a matched motor training (placebo, n = 6) group and a control group (n = 6). Further, the implicit training group significantly changed their visual search behavior by focusing on fewer locations for longer durations. In addition, the session-by-session analysis showed no significant improvement in decision accuracy between training session 1 and all the other sessions, except the last one. Coaches should devote more practice time to implicit learning approaches during perceptual-motor training program to achieve significant decision-making improvements and more efficient visual search strategy with elite athletes. © The Author(s) 2016.

While few treatment options exist for low sexual desire and arousal, the most common sexual dysfunction in women, a growing body of research supports the efficacy of mindfulness-based approaches. The mechanisms underlying improvements, and whether they are due to mindfulness practice or other treatment components, are unclear. As a result, we designed and pilot-tested an eight-session group mindfulness-based cognitive therapy for sexuality (MBCT-S) program that includes more extensive practice of mindfulness skills and closely aligns with the evidence-based MBCT program for depression and anxiety. A total of 26 women (mean age 43.9, range 25 to 63) with a diagnosis of sexual interest/arousal disorder participated in eight weekly group sessions, before and after which they completed validated questionnaires. The majority of women attended all sessions and completed the recommended at-home mindfulness exercises. Compared to baseline, women reported significant improvements in sexual desire, overall sexual function, and sex-related distress, regardless of treatment expectations, relationship duration, or low desire duration. Depressed mood and mindfulness also significantly improved and mediated increases in sexual function. These pilot data suggest that eight-session MBCT-S is feasible and significantly improves sexual function, and provide the basis for a larger randomized-controlled trial (RCT) with a longer follow-up period.

Some newly credentialed athletic trainers (ATs) pursue a postprofessional degree with a curriculum that specifically advances their athletic training practice. It is unknown how those postprofessional programs assist in their transition to practice. To gain an understanding of initiatives used by postprofessional athletic training programs to facilitate role transition from student to professional during their graduate degree programs. Qualitative study. Semistructured telephone interviews. A total of 19 program directors (10 men, 9 women) from 13 Commission on Accreditation of Athletic Training Education-accredited and 6 unaccredited postprofessional athletic training programs. Telephone interviews were recorded digitally and transcribed verbatim. For data analysis, we used the principles of general inductive approach. Credibility was maintained using peer review, member checks, and researcher triangulation. Three facilitators of transition to practice emerged: orientation sessions, mentoring, and assistantship. Participants used orientation sessions ranging from a few hours to more than 1 week to provide and discuss program polices and expectations and to outline roles and responsibilities. Faculty, preceptors, and mentors were integrated into the orientation for the academic and clinical portions of the program. All participants described a mentoring process in which students were assigned by the program or informally developed. Mentors included the assigned preceptor, a staff AT, or peer students in the program. The clinical assistantship provided exposure to the daily aspects of being an AT. Barriers to transition to practice included previous educational experiences and time management. Participants reported that students with more diverse didactic and clinical education experiences had easier transitions. The ability to manage time also emerged as a challenge. Postprofessional athletic training programs used a formal orientation session as an initial means to help the newly credentialed AT transition into the role. Mentoring provided both more informal and ongoing support during the transition.

This paper will frame the topic of the session and report on the analysis of additional data related to an ongoing research project that specifically addresses the benefits and challenges of educational programs associated with scientific research programs. In particular, the paper will present the results of a survey of professionals who lead education and public outreach programs inside NASA space science missions and programs. This survey was done in association with the NASA Scientist Communication & Involvement Working Group (SCIWG). The results of this new survey are compared to those of a similar survey of AGU session participants and presenters that was made in the fall of 2003. The fall 2003 data showed clear indications of educational benefits that were unique to having a close association with scientific research programs. The data also showed clear challenges, many of which are being addressed via the rise of the new profession of bridge-builders who endeavor to match the resources and opportunities of the research science community to genuine educational needs.

Evaluation of a primary prevention program for anxiety disorders using story books with children aged 9-12 years.

This article reports the results of a study evaluating a book-supported primary prevention program "Dominique's Handy Tricks" for anxiety disorders in children aged 9-12 years. This cognitive-behavioural program is delivered using a combination of storybooks and workshop sessions. The originality of the program comes from the use of storybooks that were not developed specifically for anxiety management. Every session is based on a story describing characters facing common stressors and how they manage to cope with their daily problems. In our randomized control trial with 46 children, participation in the program led to a significant improvement in coping skills, perceived self-efficacy, anxiety sensitivity, as well as in symptoms of anxiety and fear. The theoretical and practical elements underlying the delivery of this primary prevention program are described. It is suggested that such an approach, without any labelling specific to anxiety disorders, can be useful in primary prevention programs.

Shallow to Deep Convection Transition over a Heterogeneous Land Surface Using the Land Model Coupled Large-Eddy Simulation

NASA Astrophysics Data System (ADS)

Lee, J.; Zhang, Y.; Klein, S. A.

2017-12-01

The triggering of the land breeze, and hence the development of deep convection over heterogeneous land should be understood as a consequence of the complex processes involving various factors from land surface and atmosphere simultaneously. That is a sub-grid scale process that many large-scale models have difficulty incorporating it into the parameterization scheme partly due to lack of our understanding. Thus, it is imperative that we approach the problem using a high-resolution modeling framework. In this study, we use SAM-SLM (Lee and Khairoutdinov, 2015), a large-eddy simulation model coupled to a land model, to explore the cloud effect such as cold pool, the cloud shading and the soil moisture memory on the land breeze structure and the further development of cloud and precipitation over a heterogeneous land surface. The atmospheric large scale forcing and the initial sounding are taken from the new composite case study of the fair-weather, non-precipitating shallow cumuli at ARM SGP (Zhang et al., 2017). We model the land surface as a chess board pattern with alternating leaf area index (LAI). The patch contrast of the LAI is adjusted to encompass the weak to strong heterogeneity amplitude. The surface sensible- and latent heat fluxes are computed according to the given LAI representing the differential surface heating over a heterogeneous land surface. Separate from the surface forcing imposed from the originally modeled surface, the cases that transition into the moist convection can induce another layer of the surface heterogeneity from the 1) radiation shading by clouds, 2) adjusted soil moisture pattern by the rain, 3) spreading cold pool. First, we assess and quantifies the individual cloud effect on the land breeze and the moist convection under the weak wind to simplify the feedback processes. And then, the same set of experiments is repeated under sheared background wind with low level jet, a typical summer time wind pattern at ARM SGP site, to account for more realistic situations. Our goal is to assist answering the question: "Do the sub-grid scale land surface heterogeneity matter for the weather and climate modeling?"

In order to better understand the diurnal cycle of the Sea-Breeze (SB) in the island of Mallorca, during September 2013 and June 2014 two experimental field campaigns have been conducted in the Campos basin (at the south side). A total of 6 IOPs (clear skies and weak pressure gradient conditions) are analysed using observations taken close to the coastline (about 900 m inland) that consist on a surface portable station (equipped with a temperature and humidity probe, and one 2-D and 3-D sonic anemometers), a captive balloon (temperature and humidity) and a multicopter (temperature and humidity). Besides, observations from automatic weather stations of the AEMET network are taken as well as satellite-derived surface temperatures that together with the model outputs from high-resolution mesoscale simulations are used to better understand the organization of the flow at lower levels. With the combined inspection of observations and model results it is found that during the previous phase (after sunrise) land-breeze conditions were present and the sensible heat flux turned to positive meanwhile the turbulence started. In the preparatory phase (about 3 hours after sunrise) the wind close to the coast started to veer progressively towards the SB direction. As soon as the SB was initiated (about 5 hours after sunrise), the SB front progressed to the inland direction reaching a mature phase starting at noon. Afterwards, the SB decaying starts and close to sunset the wind speed was close to zero and veered towards the land to sea direction. During the campaign all phases were measured with special emphasis to the morning transition (from LB to SB) and the evening transition (from SB to LB) because of the strong wind shear (turbulence) reported during the mature phase. It is found that for all the different phases the model is able to capture the organization of the flow at lower levels although it experiences some difficulties in reproducing the thermal profile during the preparatory phase, when the model energy budget usually differs a lot from the observed one. Nevertheless, at the end of this phase the model agrees with the observations, showing that the general energetics of the morning transition are well captured.

Rainfall Morphology in Semi-Tropical Convergence Zones

Shepherd, J. Marshall; Ferrier, Brad S.; Ray, Peter S.

2000-01-01

Central Florida is the ideal test laboratory for studying convergence zone-induced convection. The region regularly experiences sea breeze fronts and rainfall-induced outflow boundaries. The focus of this study is the common yet poorly-studied convergence zone established by the interaction of the sea breeze front and an outflow boundary. Previous studies have investigated mechanisms primarily affecting storm initiation by such convergence zones. Few have focused on rainfall morphology yet these storms contribute a significant amount precipitation to the annual rainfall budget. Low-level convergence and mid-tropospheric moisture have both been shown to correlate with rainfall amounts in Florida. Using 2D and 3D numerical simulations, the roles of low-level convergence and mid-tropospheric moisture in rainfall evolution are examined. The results indicate that time-averaged, vertical moisture flux (VMF) at the sea breeze front/outflow convergence zone is directly and linearly proportional to initial condensation rates. This proportionality establishes a similar relationship between VMF and initial rainfall. Vertical moisture flux, which encompasses depth and magnitude of convergence, is better correlated to initial rainfall production than surface moisture convergence. This extends early observational studies which linked rainfall in Florida to surface moisture convergence. The amount and distribution of mid-tropospheric moisture determines how rainfall associated with secondary cells develop. Rainfall amount and efficiency varied significantly over an observable range of relative humidities in the 850- 500 mb layer even though rainfall evolution was similar during the initial or "first-cell" period. Rainfall variability was attributed to drier mid-tropospheric environments inhibiting secondary cell development through entrainment effects. Observationally, 850-500 mb moisture structure exhibits wider variability than lower level moisture, which is virtually always present in Florida. A likely consequence of the variability in 850-500 moisture is a stronger statistical correlation to rainfall, which observational studies have noted. The study indicates that vertical moisture flux forcing at convergence zones is critical in determining rainfall in the initial stage of development but plays a decreasing role in rainfall evolution as the system matures. The mid-tropospheric moisture (e.g. environment) plays an increasing role in rainfall evolution as the system matures. This suggests the need to improve measurements of magnitude/depth of convergence and mid-tropospheric moisture distribution. It also highlights the need for better parameterization of entrainment and vertical moisture distribution in larger-scale models.

Aerosol-cloud interactions in mixed-phase convective clouds - Part 1: Aerosol perturbations

Changes induced by perturbed aerosol conditions in moderately deep mixed-phase convective clouds (cloud top height ˜ 5 km) developing along sea-breeze convergence lines are investigated with high-resolution numerical model simulations. The simulations utilise the newly developed Cloud-AeroSol Interacting Microphysics (CASIM) module for the Unified Model (UM), which allows for the representation of the two-way interaction between cloud and aerosol fields. Simulations are evaluated against observations collected during the COnvective Precipitation Experiment (COPE) field campaign over the southwestern peninsula of the UK in 2013. The simulations compare favourably with observed thermodynamic profiles, cloud base cloud droplet number concentrations (CDNC), cloud depth, and radar reflectivity statistics. Including the modification of aerosol fields by cloud microphysical processes improves the correspondence with observed CDNC values and spatial variability, but reduces the agreement with observations for average cloud size and cloud top height. Accumulated precipitation is suppressed for higher-aerosol conditions before clouds become organised along the sea-breeze convergence lines. Changes in precipitation are smaller in simulations with aerosol processing. The precipitation suppression is due to less efficient precipitation production by warm-phase microphysics, consistent with parcel model predictions. In contrast, after convective cells organise along the sea-breeze convergence zone, accumulated precipitation increases with aerosol concentrations. Condensate production increases with the aerosol concentrations due to higher vertical velocities in the convective cores and higher cloud top heights. However, for the highest-aerosol scenarios, no further increase in the condensate production occurs, as clouds grow into an upper-level stable layer. In these cases, the reduced precipitation efficiency (PE) dominates the precipitation response and no further precipitation enhancement occurs. Previous studies of deep convective clouds have related larger vertical velocities under high-aerosol conditions to enhanced latent heating from freezing. In the presented simulations changes in latent heating above the 0°C are negligible, but latent heating from condensation increases with aerosol concentrations. It is hypothesised that this increase is related to changes in the cloud field structure reducing the mixing of environmental air into the convective core. The precipitation response of the deeper mixed-phase clouds along well-established convergence lines can be the opposite of predictions from parcel models. This occurs when clouds interact with a pre-existing thermodynamic environment and cloud field structural changes occur that are not captured by simple parcel model approaches.

Objective This study aimed to compare the effects of two frequencies of high-speed resistance training (HSRT) on physical performance and quality of life of older women. Methods A total of 24 older women participated in a 12-week HSRT program composed of either two or three sessions/week (equated for volume and intensity). Women were randomized into three arms: a control group (CG, n=8), a resistance training group performing two sessions/week (RT2, n=8), and a resistance training group performing three sessions/week (RT3, n=8). The training program for both experimental groups included exercises that required high-speed concentric muscle actions. Results No baseline differences were observed among groups. Compared with the CG, both training groups showed similar small to moderate improvements (P<0.05) in muscle strength, power, functional performance, balance, and quality of life. Conclusion These results suggest that equated for volume and intensity, two and three training sessions/week of HSRT are equally effective for improving physical performance and quality of life of older women.

Obesity in children has increased in recent years. Many studies with differing methodologies have been undertaken to treat obesity. The Control, Evaluation, and Modification of Lifestyles in Obese Youth (CEMHaVi) program is a unique 2-year health-wellness program of physical activity and health education for obese youth. Findings of this study represent results at 1-year follow-up. The purpose of this study was to evaluate the effects of the CEMHaVi program. Physician-referred subjects (N = 26) participated in the study, 14 girls (13.4 +/- 2.9 years) and 12 boys (12.3 +/- 2.8 years). Measurements included height, weight, body mass index (BMI), academic performance, sleep habits, and health knowledge. The intervention consisted of a unique program of physical activity, including a variety of games specifically selected to be enjoyable, maintain interest, and motivate subjects to adhere. Activity sessions were offered once per week, 2 hours each session, for 12 months. A health education program was offered once every 3 months for 2 hours per session. Health knowledge, academic performance, self-esteem, and sleep were assessed before and after the intervention. Means were calculated at baseline and following intervention and were compared by paired t tests. Findings suggest significant improvements in academic performance (P < .001), quality and quantity of sleep (P < .05), and obesity (P < .05). The program reduced BMI and improved health knowledge, sleep, and academic performance in obese children. The feasibility of a beneficial lifestyle intervention program is encouraging in addressing obesity and related issues in young boys and girls.

This study compared the effects of playing and nonplaying high intensity intermittent training (HIIT) on physiological demands and tennis stroke performance in young tennis players. Eleven competitive male players (13.4 ± 1.3 years) completed both a playing and nonplaying HIIT session of equal distance, in random order. During each HIIT session, heart rate (HR), blood lactate, and ratings of perceived exertion (RPE) were monitored. Before and after each HIIT session, the velocity and accuracy of the serve, and forehand and backhand strokes were evaluated. The results demonstrated that both HIIT sessions achieved an average HR greater than 90% HRmax. The physiological demands (average HR) were greater during the playing session compared to the nonplaying session, despite similar lactate concentrations and a lower RPE. The results also indicate a reduction in shot velocity after both HIIT sessions; however, the playing HIIT session had a more deleterious effect on stroke accuracy. These findings suggest that 1) both HIIT sessions may be sufficient to develop maximal aerobic power, 2) playing HIIT sessions provide a greater physiological demand with a lower RPE, and 3) playing HIIT has a greater deleterious effect on stroke performance, and in particular on the accuracy component of the ground stroke performance, and should be incorporated appropriately into a periodization program in young male tennis players.

The driving performance of individuals with mild cognitive impairment (MCI) is suboptimal when compared to healthy older adults. It is expected that the driving will worsen with the progression of the cognitive decline and thus, whether or not these individuals should continue to drive is a matter of debate. The aim of the study was to provide support to the claim that individuals with MCI can benefit from a training program and improve their overall driving performance in a driving simulator. Fifteen older drivers with MCI participated in five training sessions in a simulator (over a 21-day period) and in a 6-month recall session. During training, they received automated auditory feedback on their performance when an error was noted about various maneuvers known to be suboptimal in MCI individuals (for instance, weaving, omitting to indicate a lane change, to verify a blind spot, or to engage in a visual search before crossing an intersection). The number of errors was compiled for eight different maneuvers for all sessions. For the initial five sessions, a gradual and significant decrease in the number of errors was observed, indicating learning and safer driving. The level of performance, however, was not maintained at the 6-month recall session. Nevertheless, the initial learning observed opens up possibilities to undertake more regular interventions to maintain driving skills and safe driving in MCI individuals.

The DEVELOP National Program addresses environmental and public policy issues through interdisciplinary research projects that apply the lens of NASA Earth observations to community concerns around the globe. Part of NASA's Applied Sciences' Capacity Building Program, DEVELOP bridges the gap between NASA Earth Science and society, building capacity in both participants and partner organizations to better prepare them to handle the challenges that face our society and future generations. Teams of DEVELOP participants partner with decision makers to conduct rapid feasibility projects that highlight fresh applications of NASA's suite of Earth observing sensors, cultivate advanced skills, and increase understanding of NASA Earth Science data and technology. Part of this process involves the creation of short introductory videos that demonstrate the environmental concerns, project methodologies and results, and an overview of how this work will impact decision makers. These videos are presented to the public three times a year in 'virtual poster sessions' (VPS) that provide an interactive way for individuals from around the globe to access the research, understand the capabilities and applications of NASA's Earth science datasets, and interact with the participants through blogging and dialogue sessions. Virtual poster sessions have allowed DEVELOP to introduce NASA's Earth science assets to thousands of viewers around the world. For instance, one fall VPS had over 5,000 visitors from 89 different countries during the two week session. This presentation will discuss lessons learned and statistics related to the series of nine virtual poster sessions that DEVELOP has conducted 2011-2013.

The aim of this study was to evaluate the benefit of virtual reality-based rehabilitation on upper-extremity function in patients with brain tumor. Patients with upper-extremity dysfunction were divided into age-matched and tumor type-matched two groups. The intervention group performed the virtual reality program 30 mins per session for 9 sessions and conventional occupational therapy 30 mins per session for 6 sessions for 3 wks, whereas the control group received conventional occupational therapy alone 30 mins per session for 15 sessions for 3 wks. The Box and Block test, the Manual Function test, and the Fugl-Meyer scale were used to evaluate upper-extremity function. The Korean version of the Modified Barthel Index was used to assess activities of daily living. Forty patients completed the study (20 for each group). Each group exhibited significant posttreatment improvements in the Box and Block test, Manual Function test, Fugl-Meyer scale, and Korean version of the Modified Barthel Index scores. The Box and Block test, the Fugl-Meyer scale, and the Manual Function test showed greater improvements in shoulder/elbow/forearm function in the intervention group and hand function in the control group. Virtual reality-based rehabilitation combined with conventional occupational therapy may be more effective than conventional occupational therapy, especially for proximal upper-extremity function in patients with brain tumor. Further studies considering hand function, such as use of virtual reality programs that targeting hand use, are required.

2013-12-01

A six-session higher-functioning autism anti-stigma program incorporating descriptive, explanatory and directive information was delivered to adolescent boys and the impact upon knowledge, attitudes and behavioural intentions towards peers with autism was evaluated. Participants were seventh-, eighth- and ninth-grade students (N = 395) from regular classes in a mainstream school. Two-eighth-grade classes were randomly allocated to the intervention condition and all remaining students were either allocated to the no-intervention peer or no-intervention non-peer condition. The anti-stigma program improved the knowledge and attitudes, but not the behavioural intentions of participants towards their peers with autism. Knowledge and attitudinal changes were maintained at follow-up. There were no spill-over effects of the program to non-targeted students. These results provide some preliminary evidence for the effectiveness of multi-session anti-stigma programs incorporating combined information for adolescent students in inclusive educational environments.

The current study examined predictors of treatment use among 56 foster mothers who participated in an attachment-based intervention program for foster infants. Foster mothers' levels of treatment use were coded at early, middle, and late phases of the intervention program. Foster mothers' states of mind with regard to attachment predicted their understanding of the intervention session concepts. Specifically, autonomous foster mothers showed higher levels of understanding at the start of the intervention program, when compared with non-autonomous foster mothers. State of mind with regard to attachment also predicted foster mothers' levels of reflective functioning during the intervention sessions. Autonomous foster mothers showed higher levels of reflective functioning at early, middle, and late stages of the intervention program, when compared with non-autonomous foster mothers. The relevance of these findings for both treatment effectiveness and treatment delivery is discussed.

Context No consensus exists about the influence of compliance with neuromuscular training programs on reduction of the risk of anterior cruciate ligament (ACL) injury. Objective To systematically review and synthesize the published literature to determine if compliance with neuromuscular training is associated with reduced incidence of ACL injury in young female athletes. Data Sources We searched PubMed, SPORTDiscus, CINAHL, and MEDLINE for articles published from 1995 to 2010 using the key words anterior cruciate ligament prevention, ACL prevention, knee prevention, prospective knee prevention, neuromuscular training, and neuromuscular intervention. Study Selection Criteria for inclusion required that (1) the number of ACL injuries was reported, (2) a neuromuscular training program was used, (3) females were included as participants, (4) the study design was prospective and controlled, and (5) compliance data for the neuromuscular training program were provided. Data Extraction Extracted data included the number of ACL injuries, total number of participants per group, observation time period, number of participants who completed each session, number of sessions completed by an entire team, and number of total sessions. Attendance was calculated as the number of participants who completed each session converted into a percentage of the total number of participants. Intervention completion was calculated as the number of sessions completed by an entire team converted into a percentage of the total number of training sessions. These data were used to calculate an overall rate of compliance. Data Synthesis Six of 205 identified studies were included. Incidence rates of ACL injury were lower in studies with high rates of compliance with neuromuscular training than in studies with low compliance rates (incidence rate ratio = 0.27 [95% confidence interval = 0.07, 0.80]). Tertile analysis indicated rates of ACL injury incidence were lower in studies with high compliance rates than in studies with moderate and low compliance rates (incidence rate ratio = 0.18 [95% confidence interval = 0.02, 0.77]). Conclusions A potential inverse dose-response relationship exists between compliance with neuromuscular training and incidence of ACL injury. Attending and completing recommended neuromuscular sessions appears to be an important factor for preventing ACL injuries. PMID:23182020

Participating in a Community of Learners enhances resident perceptions of learning in an e-mentoring program: proof of concept

PubMed Central

2011-01-01

Background Community learning and e-mentoring, learning methods used in higher education, are not used to any extent in residency education. Yet both have the potential to enhance resident learning and, in the case of community learning, introduce residents to basic lifelong learning skills. We set out to determine whether residents participating in an Internet based e-mentoring program would, with appropriate facilitation, form a community of learners (CoL) and hold regular community meetings. We also determined resident and faculty perceptions of CoL and Internet sessions as effective learning experiences. Methods A six-month e-mentoring pilot was offered to 10 Radiology residents in the Aga Khan University Postgraduate Medical Education Program in Nairobi, Kenya (AKUHN) with a Professor of Radiology, located at University of Virginia, USA, acting as the e-mentor. Monthly Internet case-based teaching sessions were facilitated by the e-mentor. In addition, residents were coached by a community facilitator to form CoL and collectively work through clinical cases at weekly face-to-face CoL sessions. Event logs described observed resident activity at CoL sessions; exit survey and interviews were used to elicit perceptions of CoL and Internet sessions as effective learning experiences. Results Resident adoption of CoL behaviors was observed, including self-regulation, peer mentoring and collaborative problem solving. Analysis revealed high resident enthusiasm and value for CoL. Surveys and interviews indicated high levels of acceptance of Internet learning experiences, although there was room for improvement in audio-visual transmission technologies. Faculty indicated there was a need for a larger multi-specialty study. Conclusions The pilot demonstrated resident acceptance of community building and collaborative learning as valued learning experiences, addressing one barrier to its formal adoption in residency education curricula. It also highlighted the potential of e-mentoring as a means of expanding faculty and teaching materials in residency programs in developing countries. PMID:21266070

Medication therapy management and condition care services in a community-based employer setting.

2010-08-15

A program in which health-system pharmacists and pharmacy technicians provide medication therapy management (MTM), wellness, and condition care (disease management) services under contract with local businesses is described. The health-system pharmacy department's Center for Medication Management contracts directly with company benefits departments for defined services to participating employees. The services include an initial wellness and MTM session and, for certain patients identified during the initial session, ongoing condition care. The initial appointment includes a medication history, point-of-care testing for serum lipids and glucose, body composition analysis, and completion of a health risk assessment. The pharmacist conducts a structured MTM session, reviews the patient's test results and risk factors, provides health education, discusses opportunities for cost savings, and documents all activities on the patient's medication action plan. Eligibility for the condition care program is based on a diagnosis of diabetes, hypertension, asthma, heart failure, or hyperlipidemia or elevation of lipid or glucose levels. Findings are summarized for employers after the initial wellness screening and at six-month intervals. Patients receiving condition care sign a customized contract, establish goals, attend up to four MTM sessions per year, and track their information on a website; employers may offer incentives for participation. When pharmacists recommend adjustments to therapy or cost-saving changes, it is up to patients to discuss these with their physician. A survey completed by each patient after the initial wellness session has indicated high satisfaction. Direct cost savings related to medication changes have averaged $253 per patient per year. Total cost savings to companies in the first year of the program averaged $1011 per patient. For the health system, the program has been financially sustainable. Key laboratory values indicate positive clinical outcomes. A business model in which health-system pharmacists provide MTM and condition care services for company employees has demonstrated successful outcomes in terms of patient satisfaction, cost savings, and clinical benefits.

After the scientific rationale is given in the introduction the Terms of Reference and the proceeding of IVS Working Group 2 are presented. Then the present status and future goals of all international activities within IVS are described. In particular the current products of IVS are described in terms of accuracy, reliability, frequency of observing sessions, temporal resolution of the parameters estimated by VLBI data analysis, time delay from observing to product, i.e. time which has passed after the end of the last session included in the VLBI solution till availability of the final products and frequency of solution (in the case of "global solutions";, when all existing or a high number of VLBI sessions are used to determine so-called global parameters). All IVS products and their potential users are covered in the report. This includes the Earth orientation parameters (EOP), the reference frames (TRF and CRF), geodynamical and geophysical parameters and physical parameters. Measures which should be taken within IVS to meet the goals defined in the first steps are presented. As most of the measures are related to the observing programs, these are the main focus for improving the current status of IVS products. The report shows that due to various requirements of the different users of IVS products the following aspects must be accomplished: - significant improvement of the accuracy of VLBI products, - shorter time delay from observation to availability of results, - almost continuous temporal coverage by VLBI sessions. A first scenario of the IVS observing program for 2002 and 2003 considers an increase of observing time by about 30%-40% and includes sessions carried out by S2 and K4 technology. The midterm observing program for the next 4-5 years seems to be rather ambitious. However, it appears feasible if all efforts are concentrated and the necessary resources are made available.

How are scientific thinking skills best developed? Direct instruction vs. inquiry practice

NASA Astrophysics Data System (ADS)

Dean, David Worth, Jr.

Despite its support and adoption by most major scientific and educational organizations, some researchers have questioned whether inquiry learning is indeed the best method for acquiring the skills of inquiry. Klahr and colleagues have investigated the development of the control of variables strategy, or controlled comparison (CC), and claim that a brief session of direct instruction, characterized by explicit training of CC, as opposed to allowing children to discover CC through inquiry learning, is sufficient for acquisition, maintenance, and transfer of this core aspect of inquiry. Kuhn and colleagues, however, argue that direct instruction may be insufficient for development of the metastrategic level of understanding necessary to adequately maintain and transfer inquiry skills. In the present study, I attempt to identify the intervention most effective in supporting acquisition, maintenance, and transfer of these skills. Three groups of students received either a direct instruction session followed by standard classroom instruction (DI-only), an introductory session (without direct instruction) followed by practice sessions only (PR-only), or a direct instruction session followed by practice sessions (DI+PR). Practice sessions involved the use of a computer-based inquiry task requiring students to investigate the effects of five potential causal variables on an outcome. The two practice groups worked with this program during 12 sessions over nine weeks. They worked with structurally identical software programs during five weekly maintenance sessions. During this time, the DI-only group received standard classroom instruction. All groups were assessed on familiar and unfamiliar computer-based inquiry tasks at the conclusion of intervention (immediate assessment) and maintenance sessions (delayed assessment). Students in the two practice groups demonstrated improvement in an integrative measure of inquiry skill (valid intent, valid strategy, valid inference, and valid explanation, in combination) as well as most component measures of this skill. Performance of the two practice groups was superior to that of the DI-only group. Direct instruction conferred no additional benefit to the group receiving both direct instruction and practice compared to the practice-only group. Examined over an extended time interval, the merits of brief direct instruction are thus brought into question.

HealthSpan Physicians (HSP), an integrated medical system in Northeast Ohio, partnered with the Young Men's Christian Association (YMCA) of Greater Cleveland to implement a referral system for the evidence-based Diabetes Prevention Program (DPP) throughout HSP. The YMCA of USA employs a cost-effective, customized version of the original DPP in which coaches take the place of in-house clinical staff. Efficacy of the YMCA DPP was shown earlier in the DEPLOY Study. To improve outcomes of metrics used in the DEPLOY Study. Observational study focusing on engagement, persistence, recruitment, and adherence to the DPP. In August 2014, HSP mailed an invitation to 2200 patients identified as both Medicare eligible and at risk of prediabetes to attend no-obligation information sessions about the DPP. After these sessions, YMCA staff called interested participants and asked them to enroll in and to commit to the program. Motivation and reinforcement were provided to patients through YMCA-provided signs, brochures, and posters; the HSP Web site; and in-person conversations with primary care physicians. Average weight loss at the end of 16 weeks in the program and average retention through Session 9. Of the 2200 patients contacted, 351 (16.0%) responded by attending the information session, and 228 enrolled in the YMCA DPP (11.3%) and persisted through at least Week 9. This result is an improvement over the 1.7% of eligible enrollees who responded to the DEPLOY Study's mailing. A marketing approach to implementing the YMCA DPP in an integrated medical system results in excellent outcomes.

The ESCOMPTE Campaign has been conducted over Southern France (Provence region including the Marseille, Aix and Toulon cities and the Fos-Berre industrial center) in June and July of 2001. In order to study the redistribution of the pollutants emitted by anthropic and biogenic emissions and their impact on the atmospheric chemistry, we used meso-scale modeling (RAMS model, paralleled version 4.3, coupled on line with chemical modules : MOCA2.2 (Poulet et al, 2002) including 29 gaseous species). The hourly high resolution emissions were obtained from ESCOMPTE database (Ponche et al, 2002). The model was coupled with the dry deposition scheme (Walmsley and Weseley,1996). In this particular case of complex circulation (sea breeze associated with topography), the processes involving peaks of pollution were strongly non linear, and the meso scale modeling coupled on line with chemistry module was an essential step for a realistic redistribution of chemical species. Two nested grids satisfactorily describe the synoptic dynamics and the sea breeze circulations. The ECMWF meteorological fields provide the initial and boundary conditions. Different events characterized by various meteorological situations were simulated. Meteorological fields retrieved by modeling, also Modeled ozone, NOx, CO and SO2 concentrations, were compared with balloons, lidars, aircrafts and surface stations measurements. The chemistry regimes were explained according to the distribution of plumes. The stratified layers were examined.

Spatial and temporal variability of PM levels and composition in a complex summer atmospheric scenario in Barcelona (NE Spain)

Viana, M.; Pérez, C.; Querol, X.; Alastuey, A.; Nickovic, S.; Baldasano, J. M.

Summer atmospheric coastal dynamics exert a significant influence on the levels and composition of atmospheric particulate matter (PM) in the North-Eastern Iberian Peninsula. Summer atmospheric scenarios in this region present a high degree of complexity as they are characterised by the absence of synoptic-scale air mass advections, the development of breeze circulations, enhanced photochemistry, local mineral dust re-suspension and the occurrence of African dust outbreaks. Three sampling sites were selected in Barcelona (NE Spain), an urban coastal site surrounded by complex topography. Regional dust modelling (DREAM) and high resolution meteorological modelling (MM5) were used to interpret PM levels and composition at the three sites. The results outline the effect of breeze dynamics and thermal internal boundary layer formation as the main meteorological drivers of the hourly evolution of PM levels. Levels of crustal components, secondary inorganic and carbon species are higher during the night, and only the marine aerosol content is higher during the day. Nitrate levels are higher during the night due to the thermal stability on NH 4NO 3. Sulphate levels are higher during the night as a consequence of the drainage flows. Lidar measurements and model results signalled the occurrence of two African dust episodes during the study period which mainly affected the free troposphere over Barcelona.

Andrade, Fatima; Orsini, Celso; Maenhaut, Willy

Stacked filter units were used to collect atmospheric particles in separate coarse and fine fractions at the Sao Paulo University Campus during the winter of 1989. The samples were analysed by particle-induced X-ray emission (PIXE) and the data were subjected to an absolute principal component analysis (APCA). Five sources were identified for the fine particles: industrial emissions, which accounted for 13% of the fine mass; emissions from residual oil and diesel, explaining 41%; resuspended soil dust, with 28%; and emissions of Cu and of Mg, together with 18%. For the coarse particles, four sources were identified: soil dust, accounting for 59% of the coarse mass; industrial emissions, with 19%; oil burning, with 8%; and sea salt aerosol, with 14% of the coarse mass. A data set with various meteorological parameters was also subjected to APCA, and a correlation analysis was performed between the meteorological "absolute principal component scores" (APCS) and the APCS from the fine and coarse particle data sets. The soil dust sources for the fine and coarse aerosol were highly correlated with each other and were anticorrelated with the sea breeze component. The industrial components in the fine and coarse size fractions were also highly positively correlated. Furthermore, the industrial component was related with the northeasterly wind direction and, to a lesser extent, with the sea breeze component.

Modelling study of sea breezes in a complex coastal environment

Cai, X.-M.; Steyn, D. G.

This study investigates a mesoscale modelling of sea breezes blowing from a narrow strait into the lower Fraser valley (LFV), British Columbia, Canada, during the period of 17-20 July, 1985. Without a nudging scheme in the inner grid, the CSU-RAMS model produces satisfactory wind and temperature fields during the daytime. In comparison with observation, the agreement indices for surface wind and temperature during daytime reach about 0.6 and 0.95, respectively, while the agreement indices drop to 0.4 at night. In the vertical, profiles of modelled wind and temperature generally agree with tethersonde data collected on 17 and 19 July. The study demonstrates that in late afternoon, the model does not capture the advection of an elevated warm layer which originated from land surfaces outside of the inner grid. Mixed layer depth (MLD) is calculated from model output of turbulent kinetic energy field. Comparison of MLD results with observation shows that the method generates a reliable MLD during the daytime, and that accurate estimates of MLD near the coast require the correct simulation of wind conditions over the sea. The study has shown that for a complex coast environment like the LFV, a reliable modelling study depends not only on local surface fluxes but also on elevated layers transported from remote land surfaces. This dependence is especially important when local forcings are weak, for example, during late afternoon and at night.

There are a number of neurocognitive and behavioral mechanisms that contribute to overeating and obesity, including an attentional bias to food cues. Attention modification programs, which implicitly train attention away from specific cues, have been used in anxiety and substance abuse, and could logically be applied to food cues. The purpose of this study was to evaluate the initial efficacy of a single session attention modification training for food cues (AMP) on overeating in overweight and obese children. Twenty-four obese children who eat in the absence of hunger participated in two visits and were assigned to an attention modification program (AMP) or attentional control program (ACC). The AMP program trained attention away 100% of the time from food words to neutral words. The ACC program trained attention 50% of the time to neutral and 50% of the time to food. Outcome measures included the eating in the absence of hunger free access session, and measures of craving, liking and salivation. Results revealed significant treatment effects for EAH percent and EAH kcal (group by time interactions p<.05). Children in the ACC condition showed a significant increase over time in the number of calories consumed in the free access session (within group t=3.09, p=.009) as well as the percent of daily caloric needs consumed in free access (within group t=3.37, p=.006), whereas children in the AMP group demonstrated slight decreases in these variables (within group t=-0.75 and -0.63, respectively). There was a trend suggesting a beneficial effect of AMP as compared to ACC for attentional bias (group by time interaction p=.073). Changes in craving, liking and saliva were not significantly different between groups (ps=.178-.527). This is the first study to demonstrate that an AMP program can influence eating in obese children. Larger studies are needed to replicate and extend these results. Copyright © 2014.

Chief Residents must lead, manage and mentor a diverse and often large group of residents, however there is a lack of formal leadership training throughout graduate medical education. Development of a 3-part Chief Resident (CR) Program focused on leading, managing and mentoring. Each participant completes an Emotional Intelligence (EI) Inventory prior to the day-long event. Participants receive their EI scores at the beginning of the program, which features interactive sessions on leadership, management, and feedback skills. The program then reinforces the application of their new knowledge about EI through a four station OSTE (Observed Structured Teaching Encounter). CRs practice feedback and coaching skills in a simulated environment where they need to provide the context of formative feedback to a standardized resident. The aggregated mean pre-session EI score for all participants was 76.9 (an ideal score is >85). An independent-samples t-test compared the CRs' leadership and feedback performance on their first and second OSTE performance within a single afternoon session. There was a significant difference between the first OSTE performance (M = 47.92, SD = 7.8) and the second OSTE performance (M = 51.22, SD = 6.9); t (68) = 1.99, p = 0.006. These results suggest that participating in multiple OSTEs positively reinforces the core interpersonal and communication skills discussed in the didactic and practiced in the interactive portions of the program. The low mean pre-session EI score achieved by our participants supports the idea that CRs enter their new roles with a level of EI that can be enhanced. CRs had an overall positive reaction to EI and its application to the core skills addressed in the program, highlighting the fact that similar programs could be used to train early career physicians to be more skilled and comfortable with leading, managing and mentoring. CR: Chief resident; EI: Emotional intelligence; GME: Graduate medical education; OSTE: Objective structured teaching encounter.

The Nephrology Quiz and Questionnaire remains an extremely popular session for attendees of the annual Kidney Week meeting of the American Society of Nephrology. During the 2015 meeting the conference hall was once again overflowing with eager quiz participants. Topics covered by the experts included electrolyte and acid-base disorders, glomerular disease, end-stage renal disease and dialysis, and kidney transplantation. Complex cases representing each of these categories together with single-best-answer questions were prepared and submitted by the panel of experts. Before the meeting, training program directors of nephrology fellowship programs and nephrology fellows in the United States answered the questions through an internet-based questionnaire. During the live session members of the audience tested their knowledge and judgment on the same series of case-oriented questions in a quiz. The audience compared their answers in real time using a cell-phone app containing the answers of the nephrology fellows and training program directors. The results of the online questionnaire were displayed, and then the quiz answers were discussed. As always, the audience, lecturers, and moderators enjoyed this highly educational session. This article recapitulates the session and reproduces selected content of educational value for theClinical Journal of the American Society of Nephrologyreaders.

The economic burden of inactivity is substantial, with conservative estimates suggesting the global cost to health care systems is more than US$50 billion. School-based programs, including physical education and school sport, have been recommended as important components of a multi-sector, multi-system approach to address physical inactivity. Additionally, community sporting clubs and after-school programs (ASPs) offer further opportunities for young people to be physically active outside of school. Despite demonstrating promise, current evidence suggests school-based physical activity programs, community sporting clubs and ASPs are not achieving their full potential. For example, physical activity levels in physical education (PE) and ASP sessions are typically much lower than recommended. For these sessions to have the strongest effects on young people's physical activity levels and their on-going physical literacy, they need to improve in quality and should be highly active and engaging. This paper presents the Supportive, Active, Autonomous, Fair, Enjoyable (SAAFE) principles, which represent an evidence-based framework designed to guide the planning, delivery and evaluation of organized physical activity sessions in school, community sport and ASPs. In this paper we provide a narrative and integrative review of the conceptual and empirical bases that underpin this framework and highlight implications for knowledge translation and application.
