You stupid, lazy kid : perceptions of verbal aggressiveness in older adults
Young adults\u27 stereotypes of older adults has been well-documented in communication literature, however, there has been a lack of research on the impact of message strategy on intergenerational interactions. The purpose of this study was to examine the relationship among three factors that previous research suggests should influence the activation of stereotypes toward a target: age, relational level, and message strategy. This study examines the role that message strategy, in this case, verbal aggressiveness, plays in activating young adults\u27 (n = 186) negative stereotypes of older adults. The young adults\u27 self-reported levels of trait verbal aggressiveness was positively correlated with negative stereotype activation. Verbally aggressive messages, also, consistently activated more negative stereotypes than did the corresponding neutral message strategy. Although all three factors (age, relational level, and message strategy) accounted for differences in stereotype activation, message strategy had the largest effect on negative stereotype activation. Implications of the findings on intergenerational interactions are discussed
Toward a new understanding of wisdom: the role of communication on perceptions of wisdom
Wisdom is a multi-faceted, multi-dimensional, multidisciplinary construct which has been discussed and examined since the beginning of recorded history. Many classical and contemporary scholars have sought to define wisdom, but a precise definition has proven elusive. Since wisdom often defies easy categorization, this dissertation examines wisdom using a multi-methodological perspective. Four chapters of this dissertation discuss the historiography of various societal attributions of wisdom using performance studies techniques. Three chapters examine wisdom and the instruments constructed to measure the construct from a social scientific approach. This study seeks to clarify, while simultaneously deconstructing, the definition of wisdom. The four performative chapters address wisdom primarily from the perspective of Gregory Ulmer\u27s mystory. The three social scientific chapters discuss the existing social scientific literature, information about the sample and questionnaire, and the results of the statistical analysis of the 12 hypotheses and 17 research questions posed. The discussion considers how the methodologies used clarify and obscure wisdom. Conclusions about the elusive nature of wisdom are posited. The role of different methodological approaches, age, and poor performance of existing wisdom scales suggest directions for future research
The Autobot-WQ: A portable, low-cost autosampler to provide new insight into urban spatio-temporal water quality dynamics
Performance of English stop smoking services in first 10 years: analysis of service monitoring data
Objectives: To analyse the performance of the English Stop Smoking Services from 2001/02 to 2010/11.
Design: Analysis of national service monitoring data.
Setting: England.
Participants: Smokers recorded as having been treated by English stop smoking services between April 2001 and March 2011.
Main outcome measures: Annual figures for the number of quit dates set (throughput), the percentage of these that led to biochemically verified abstinence after four weeks (four week quit rate), and the âimpactâ in terms of the number of four week quitters beyond those who it is
estimated would have stopped with only a prescription for smoking cessation treatment; characteristics of smokers being treated, medication used, and mode of delivery (for example, one to one, group based); variability across local services in throughput, four week quit rates, and impact for 2010/11.
Results: Throughput rose from 227 335 in 2001/02 to 787 527 (8% of all smokers) in 2010/11. The percentage of four week quitters declined slightly from 35% to 34%. Impact rose from 22 933 four week quitters created in 2001/02 to 72 411 in 2010/11 (corresponding to an estimated 21 723 12 month quitters). The services were successful in reaching
disadvantaged smokers; 54% (n=425 684) were in receipt of free prescriptions in 2010/11. Substantial variation existed across local services in throughput, success rates, and impact.
Conclusions: The English stop smoking services have had an increasing impact in helping smokers to stop in their first 10 years of operation and have successfully reached disadvantaged groups. However, performance across local services has varied considerably

Racial differences in smoking abstinence rates in a multicenter, randomized, open-label trial in the United States
Background: This study evaluates differences in smoking abstinence between white and minority smokers using pharmaceutical aids. Methods: This is an analysis of data from a multi-center, randomized, clinical trial conducted in the United States. Of the 1,684 subjects randomized to one of three medications (nicotine inhaler, bupropion, or a combination of both), 60% were women and 10% were minority races. Results: Factors associated with a decreased likelihood of smoking at 12 weeks were older age (OR = 0.971, p\u3c 0.0001), being married (OR = 0.678, p= 0.0029), using bupropion SR (OR = 0.480, pâ\u3câ0.0001), and using combination therapy (OR = 0.328, pâ\u3câ0.0001). Factors associated with an increased likelihood of smoking were higher tobacco dependence scores (OR = 1.244, p \u3c 0.0001), prior quit attempts (OR = 1.812, p=0.004), and being a minority (OR = 1.849, p=0.0083). Compared to white smokers, minority smokers were significantly older at time of study entry (46 vs. 42 years, p\u3c 0.0001), less likely to be married (35% vs. 59%, p\u3c 0.0001), older at smoking initiation (21 vs. 19 years of age, p\u3c 0.0001), and had a lower abstinence rate (16% vs. 26%, p=0.0065). Conclusion: Regardless of the treatment used, minority smokers in the US have lower smoking abstinence after treatment for tobacco dependence. Future research should focus on the improvement in treatment strategies for minority smokers
The Autobot-WQ: A portable, low-cost autosampler to provide new insight into urban spatio-temporal water quality dynamics
Urbanization and the increase in urban land cover are growing concerns associated with numerous negative impacts on surface water quality. Currently, many emerging contaminants are difficult to measure with no field deployable sensors currently available. Hence, discrete grab samples are required for subsequent laboratory analysis. To capture the spatiotemporal variability in pollution pulses, autosamplers can be used, but commercial offerings are both expensive and have a large footprint. This can be problematic in urban environments where there is a high density of point source inputs and risk of vandalism or theft. Here, we present a small and robust low-cost autosampler that is ideally suited for deployment in urban environments. The design is based on âoff the shelfâ open-source hardware components and software and requires no prior engineering, electronics, or computer programming experience to build. The autosampler uses a small peristaltic pump to enable collection of 14 small volume samples (50Â mL) and is housed in a small footprint camera case. To illustrate the technology, we present two use cases for rapid sampling of stormwater pulses of: 1) an urban river channel and 2) green roof runoff. When compared with a commercial autosampler, our device showed comparable results and enabled us to capture temporal dynamics in key water quality parameters (e.g., dissolved organic matter) following rain events in an urban stream. Water quality differences associated with differing green roof design/maintenance regimes (managed and unmanaged vegetation) were captured using the autosampler, highlighting how unmanaged vegetation has a greater potential for mitigating the rapid runoff and peaked pollutant inputs associated with impervious surfaces. These two case studies show that our portable autosampler provides capacity to improve understanding of the impact of urban design and infrastructure on water quality and can lead to the development of more effective mitigation solutions. Finally, we discuss opportunities for further technical refinement of our autosampler and applications to improve environmental monitoring. We propose a holistic monitoring approach to address some of the outstanding challenges in urban areas and enable monitoring to shift from discrete point sources towards characterization of catchment or network scale dynamics
Robot Assisted Surgical Ward Rounds: Virtually Always There
Background:  While an explosion in technological sophistication has revolutionized surgery within the operating theatre, delivery of surgical ward-based care has seen little innovation. Use of telepresence allowing off-site clinicians communicate with patients has been largely restricted to outpatient settings or use of complex, expensive, static devices. We designed a prospective study to ascertain feasibility and face validity of a remotely controlled mobile audiovisual drone (LUCY) to access inpatients.  This device is, uniquely, lightweight, freely mobile and emulates âhumanâ interaction by swiveling and adjusting height to patientsâ eye-level.   Methods: Robot-assisted ward rounds(RASWR) were conducted over 3 months. A remotely located consultant surgeon communicated with patients/bedside teams via encrypted audiovisual telepresence robot (DoubleRoboticstm, California USA). Likert-scale satisfaction questionnaires, incorporating free-text sections for mixed-methods data collection, were disseminated to patient and staff volunteers following RASWRs. The same cohort completed a linked questionnaire following conventional (gold-standard) rounds, acting as control group. Data were paired, and non-parametric analysis performed.  Results: RASWRs are feasible (>90% completed without technical difficulty). The RASWR(n=52 observations) demonstrated face validity with strong correlations (r>0.7; Spearman, p-value <0.05) between robotic and conventional ward rounds among patients and staff on core themes, including dignity/confidentiality/communication/satisfaction with management plan. Patients (96.08%, n=25) agreed RASWR were a satisfactory alternative when consultant physical presence was not possible. There was acceptance of nursing/NCHD cohort (100% (n=11) willing to regularly partake in RASWR).  Conclusion: RASWRs receive high levels of patient and staff acceptance, and offer a valid alternative to conventional ward rounds when a consultant cannot be physically present
Subarctic catchment water storage and carbon cycling â Leading the way for future studies using integrated datasets at Pallas, Finland
Subarctic ecohydrological processes are changing rapidly, but detailed and integrated ecohydrological investigations are not as widespread as necessary. We introduce an integrated research catchment site (Pallas) for atmosphere, ecosystems, and ecohydrology studies in subarctic conditions in Finland that can be used for a new set of comparative catchment investigations. The Pallas site provides unique observational data and high-intensity field measurement datasets over long periods. The infrastructure for atmosphere- to landscape-scale research in ecosystem processes in a subarctic landscape has recently been complemented with detailed ecohydrological measurements. We identify three dominant processes in subarctic ecohydrology: (a) strong seasonality drives ecohydrological regimes, (b) limited dynamic storage causes rapid stream response to water inputs (snowmelt and intensive storms), and (c) hydrological state of the system regulates catchment-scale dissolved carbon dynamics and greenhouse (GHG) fluxes. Surface water and groundwater interactions play an important role in regulating catchment-scale carbon balances and ecosystem respiration within subarctic peatlands, particularly their spatial variability in the landscape. Based on our observations from Pallas, we highlight key research gaps in subarctic ecohydrology and propose several ways forward. We also demonstrate that the Pallas catchment meets the need for sustaining and pushing the boundaries of critical long-term integrated ecohydrological research in high-latitude environments.Peer reviewe
