Social Media for Disaster Management: Operational Value of the Social Conversation
No full textDisaster relief organizations increasingly engage in social conversations to inform social media users about activities such as evacuation routes and aid distribution. Concurrently, users share information such as the demand for aid, willingness to donate and availability to volunteer through social conversations with relief organizations. We investigate the eect of this information exchange on social engagement during disaster preparedness, response and recovery. We propose that the eect of information on social engagement increases from preparedness to response and decreases from response to recovery. Some of the information exchanged in social conversations is actionable as well. We propose, however, that the eect of actionable information reaches its lowest point during disaster response. To test our theory, we use Facebook data from ve benchmark organizations that responded to Hurricane Sandy in 2012. We analyze all of the organizations' posts and users' comments during a three-week period before, during and after Hurricane Sandy. Our ndings support our theory. Furthermore, we identify an opportunity for relief organizations to improve their use of social media for disaster management. While relief organizations focus on informing disaster victims about aid distribution, most users are asking about how they as individuals can donate or volunteer. Thus, besides posting information directed to victims, organizations should post more information targeting potential donors and volunteers
How to Review Conference Proposals (and Why You Should Bother)
Get PDFThis essay provides advice for effectively reviewing conference proposals, including how to write comments that are helpful to proposal authors, how to use the “comments to program chair” box, and issues to consider when assigning proposal ratings and recommending acceptance or rejection. Several benefits of reviewing proposals are outlined, along with advice for becoming a reviewer. This essay is situated within the AERA conference context and considers how reviewing conference proposals differs from that of journal articles. Still, much of the advice provided is applicable to scholarly reviewing, more generally
Examining Age as a Potential Moderator of Response to Reduced Nicotine Content Cigarettes in Vulnerable Populations
No full textIntroduction: Young adults (aged 18–24 years) have a higher smoking prevalence than younger and older age groups and young adulthood is an important developmental period during which long-term behavior patterns like cigarette smoking are established. The aim of the current study was to examine how young adult smokers with additional vulnerabilities to smoking respond to reduced nicotine content cigarettes. Methods: This is a secondary analysis of a double-blind, within-subject experiment conducted with 169 cigarette smokers recruited from populations with comorbid psychiatric conditions or socioeconomic disadvantage assessing acute effects of research cigarettes varying in nicotine content (0.4, 2.4, 5.2, 15.8 mg/g). Participants were dichotomized by chronological age (18–24 vs. ≥25 years). Across 14 laboratory sessions effects of nicotine content were examined on measures of relative reinforcing efficacy (Cigarette Purchase Task [CPT] and Concurrent Choice testing), subjective effects, craving/withdrawal, and smoking topography. Repeated measures analysis of variances were used to examine potential moderating effects of age. Results: Young adults exhibited lower demand for reduced nicotine content cigarettes than older adults across three of five CPT indices (ps < .05). No differences by age were observed on other measures of reinforcing efficacy, subjective effects, craving/withdrawal, or smoking topography where effects generally decreased as an orderly function of decreasing nicotine content (ps <.05). Conclusion: Overall, these findings suggest that reducing the nicotine content of cigarettes would decrease the addiction potential of cigarette smoking in young adult smokers as much or perhaps more than older adult smokers from populations at increased vulnerability to smoking, addiction, and smoking-related health consequences. Implications: Reducing the nicotine content in cigarettes to lower addiction potential of smoking has been proposed as a means to improve overall population health. It is imperative to examine how young adults may respond to a nicotine reduction policy. We saw minimal evidence that age moderates acute response and where there was evidence it was in the direction of reduced nicotine content cigarettes having less addictive potential among young versus older adults (eg, steeper decreases in demand for very low nicotine content cigarettes among young versus older adults). Overall, a nicotine reduction policy has the potential to reduce smoking across age groups
Underage drinking, alcohol dependence, and young people starting to use prescription pain relievers extra-medically: A zero-inflated Poisson regression model.
No full textAmong young people who start using prescription pain relievers (PPRs) for feeling-states such as “to get high” or otherwise beyond boundaries intended by prescribers, the most recent epidemiological incidence estimates show 2%–9% with rapid-onset opioid dependence. In this work, we study recently active underage alcohol dependence as a susceptibility marker and estimate alcohol dependence-associated PPR rates of use, once use starts. In recent U.S. epidemiological samples, we identified 16,125 community-dwelling 12-to-20-year-olds with standardized assessments of both problem drinking and newly incident extra-medical PPR use. We applied zero-inflated Poisson (ZIP) regressions to estimate (a) alcohol dependence associations with susceptibility-to-persist after the very first occasion of extra-medical PPR use, and (b) the rate of PPR use, conditional on persistence. Underage drinkers with alcohol dependence were more susceptible to persistence in their extra-medical PPR use (p < .001). In addition, given susceptibility-to-persistence, there was an alcohol dependence-associated excess rate of extra-medical PPR use (risk ratio = 1.3; 95% confidence interval = 1.1, 1.6). Using ZIP regressions, we can see that underage alcohol dependence signals membership in a susceptible-to-persistence class of extra-medical PPR users and excess rates of extra-medical use. Underage drinking can be an indicator of greater vulnerability to start and persist in extra-medical use of PPR, particularly if presenting clinical features of alcohol dependence already are seen at or near time of first onset of such PPR use. For alcohol dependence-affected adolescent patients, nondrug pain management plans deserve consideration, with special surveillance if analgesic drugs are prescribed. Implications for genetic susceptibility research are discussed
Analyzing the relationship between stadium location and attendance: A location modeling of Major League Baseball (MLB)
No full textThe location of a sports facility is one of the significant factors in economically operating and maintaining the facility. The present study used a location theory model to examine the influence of the Major League Baseball (MLB) stadium location on attendance (N=348) for the 2006-2017 MLB regular seasons, taking into consideration the population, median income, and distance between the stadium and the population center of counties nearby the stadium. The optimal location model was determined as the inverse proportion of the squared distance of the first nearest county, and location significantly influenced the attendance (p<.05). Then, based on the results of the location model, the current study analyzed the relationship between the MLB attendance and other attendance determinants by using hierarchical linear modeling. Among 14 different determinants, six variables (i.e., stadium capacity, ticket price, season, as well as the home team’s quality, payroll, and star players) were revealed in the findings to have a significant influence on the MLB attendance (p<.05)
Chemical abundances of open clusters from high-resolution infrared spectra - II. NGC 752
No full textWe present a detailed near-infrared chemical abundance analysis of 10 red giant members of the Galactic open cluster NGC 752. High-resolution (R ≃ 45000) near-infrared spectral data were gathered with the Immersion Grating Infrared Spectrograph, providing simultaneous coverage of the complete H and K bands. We derived the abundances of H-burning (C, N, O), (Mg, Si, S, Ca), light odd-Z (Na, Al, P, K), Fe-group (Sc, Ti, Cr, Fe, Co, Ni), and neutron-capture (Ce, Nd, Yb) elements. We report the abundances of S, P, K, Ce, and Yb in NGC 752 for the first time. Our analysis yields solar-metallicity and solar abundance ratios for almost all of the elements heavier than the CNO group in NGC 752. O and N abundances were measured from a number of OH and CN features in the H band, and C abundances were determined mainly from CO molecular lines in the K band. High-excitation CI lines present in both near-infrared and optical spectra were also included in the C abundance determinations. Carbon isotopic ratios were derived from the R-branch band heads of first overtone (2−0) and (3−1) CO and (2−0) CO lines near 23 440 Å and (3−1) CO lines at about 23 730 Å. The CNO abundances and C/C ratios are all consistent with our giants having completed ‘first dredge-up’ envelope mixing of CN-cyle products. We independently assessed NGC 752 stellar membership from Gaia astrometry, leading to a new colour–magnitude diagram for this cluster. Applications of Victoria isochrones and MESA models to these data yield an updated NGC 752 cluster age (1.52 Gyr) and evolutionary stage indications for the programme stars. The photometric evidence and spectroscopic light element abundances all suggest that the most, perhaps all of the programme stars are members of the helium-burning red clump in this cluster
Family Environment in Children With Hearing Aids and Cochlear Implants: Associations With Spoken Language, Psychosocial Functioning, and Cognitive Development
No full textObjectives: To examine differences in family environment and associations between family environment and key speech, language, and cognitive outcomes in samples of children with normal hearing and deaf and hard-of-hearing (DHH) children who use hearing aids and cochlear implants. Design: Thirty families of children with normal hearing (n = 10), hearing aids (n = 10), or cochlear implants (n = 10) completed questionnaires evaluating executive function, social skills, and problem behaviors. Children's language and receptive vocabulary were evaluated using standardized measures in the children's homes. In addition, families were administered a standardized in-home questionnaire and observational assessment regarding the home environment. Results: Family environment overall was similar across hearing level and sensory aid, although some differences were found on parental responsivity and physical environment. The level of supportiveness and enrichment within family relationships accounted for much of the relations between family environment and the psychosocial and neurocognitive development of DHH children. In contrast, the availability of objects and experiences to stimulate learning in the home was related to the development of spoken language. Conclusions: Whereas broad characteristics of the family environments of DHH children may not differ from those of hearing children, variability in family functioning is related to DHH children's at-risk speech, language, and cognitive outcomes. Results support the importance of further research to clarify and explain these relations, which might suggest novel methods and targets of family-based interventions to improve developmental outcomes
The Cultural Politics of Dan Quayle and Mike Pence
No full textThis essay was part of an Indiana Law Review symposium on the five U.S. vice presidents who have hailed from Indiana. The Gallup polling organization classifies Indiana as a “pink” state, rather than a “red” state, meaning it leans Republican but is not solidly in the GOP column. Yet, if an image of Indiana persists in many people’s minds as a bastion of social conservatism and tradition, that image likely has been shaped in part by the two most recent vice presidents the Hoosier state has sent to Washington: Dan Quayle and Mike Pence. In selecting their running mates, major party presidential candidates typically look for someone with strengths or experience that the person at the top of the ticket lacks. Both Quayle and Pence were chosen, to a large degree, because they were seen as effective and important ambassadors to social and religious conservatives — a group that was not the natural constituency of their senior running mates, George H.W. Bush and Donald Trump, respectively. Barring some event that elevates Pence to the presidency, this is how both Quayle and Pence are likely to be remembered by history: As great favorites, even paragons, of the religious right, and as loyal political subalterns whose job was to carry the torch for “family values,” opposition to abortion and LGBT rights, and a greater role for religion in American public life
A guide for proper utilisation of stable isotope reference materials
No full textMany scientific publications about stable isotope ratios suffer from flawed practices regarding calibration and normalisation of raw δ values in conjunction with prescribed δ values of reference materials. Violations of the identical treatment principle with regards to samples and standards (i.e. reference materials) and lack of adherence to SI-mandated and IUPAC-recommended nomenclature exacerbate the widespread problem of lackadaisical analytical practice and reporting. Science is supposed to strive for exactness, whereas ambiguity and jargon confound interdisciplinary communication. This contribution aims to expose typical misconceptions and avoidable errors and offers guidance toward the reproducible generation of isotope data, isotopic scale normalisation, and proper data reporting. We offer a comprehensive overview of sources of light stable isotope reference materials to best match sample matrices encountered by stable isotope practitioners with chemically similar reference materials
