Published: October 2018

ABSTRACTIntroductionHome health agencies have been tasked to improve their patients’ disaster preparedness. Few studies have evaluated the robustness of tools to support preparedness in home health. Through evaluation of the Home-Based Primary Care (HBPC) Patient Assessment Tool, we conducted a survey to identify strengths and challenges in supporting the preparedness of patients served by home health programs such as the Veterans Health Administration’s HBPC program.MethodsPractitioners from 10 HBPC programs fielded the Patient Assessment Tool with all patients during a 3-week period. Logistic regression and bivariate analyses were used to identify patient characteristics associated with the delivery of preparedness education.ResultsA total of 754 Patient Assessment Tools were returned. The educational item most likely to be covered was how to activate 911 services (87%). The item least likely to be discussed was information on emergency shelter registration and emergency specialty transportation (44%). When compared to the low risk group, HBPC patients in the high/medium risk group were more likely to receive preparedness education materials for 6 of the 9 educational preparedness items (P values less than 0.05).DiscussionPractitioners are relaying preparedness education to their most vulnerable patients, suggesting that home health agencies can provide disaster preparedness in the home. Nonetheless, there is room for improvement. (Disaster Med Public Health Preparedness. 2019;13:547-554)
FREE ACTIONS OF SOME COMPACT GROUPS ON MILNOR MANIFOLDS
Authors: DEY PINKA , SINGH MAHENDER 
Published: October 2018

AbstractIn this paper, we investigate free actions of some compact groups on cohomology real and complex Milnor manifolds. More precisely, we compute the mod 2 cohomology algebra of the orbit space of an arbitrary free ℤ2 and $\mathbb{S}^1$-action on a compact Hausdorff space with mod 2 cohomology algebra of a real or a complex Milnor manifold. As applications, we deduce some Borsuk–Ulam type results for equivariant maps between spheres and these spaces. For the complex case, we obtain a lower bound on the Schwarz genus, which further establishes the existence of coincidence points for maps to the Euclidean plane.

Published: October 2018

AbstractObjectiveAnteriorly located tympanic membrane perforations can negatively affect surgical success rates. This study aimed to present, using our case series results, endoscopic triple-C (composite chondroperichondrial clip) tympanoplasty as an alternative method in the repair of tympanic membrane anterior quadrant perforations.MethodsThis study included patients with a perforation sized greater than 3 mm, who had an anterior quadrant dominant perforation where the anterior portion could not be seen during microscopic examination; all underwent endoscopic triple-C tympanoplasty.ResultsOperating time was 30–79 minutes (mean, 46.6 minutes). The post-operative graft success rate at six months was 92 per cent (23 out of 25). Mean post-operative follow-up duration was 21.5 ± 7.3 months (range, 11–40 months), and no intratympanic cholesteatoma was observed.ConclusionEndoscopic triple-C tympanoplasty is a comfortable, minimally invasive alternative method to repair anterior tympanic membrane perforations. The graft success rate and the degree of recovery from hearing loss were in accordance with the literature. However, more reliable results may be obtained in a larger series with longer follow-up times.

AbstractBackgroundThe prevalence of mental disorders among Black, Latino, and Asian adults is lower than among Whites. Factors that explain these differences are largely unknown. We examined whether racial/ethnic differences in exposure to traumatic events (TEs) or vulnerability to trauma-related psychopathology explained the lower rates of psychopathology among racial/ethnic minorities.MethodsWe estimated the prevalence of TE exposure and associations with onset of DSM-IV depression, anxiety and substance disorders and with lifetime post-traumatic stress disorder (PTSD) in the Collaborative Psychiatric Epidemiology Surveys, a national sample (N = 13 775) with substantial proportions of Black (35.9%), Latino (18.9%), and Asian Americans (14.9%).ResultsTE exposure varied across racial/ethnic groups. Asians were most likely to experience organized violence – particularly being a refugee – but had the lowest exposure to all other TEs. Blacks had the greatest exposure to participation in organized violence, sexual violence, and other TEs, Latinos had the highest exposure to physical violence, and Whites were most likely to experience accidents/injuries. Racial/ethnic minorities had lower odds ratios of depression, anxiety, and substance disorder onset relative to Whites. Neither variation in TE exposure nor vulnerability to psychopathology following TEs across racial/ethnic groups explained these differences. Vulnerability to PTSD did vary across groups, however, such that Asians were less likely and Blacks more likely to develop PTSD following TEs than Whites.ConclusionsLower prevalence of mental disorders among racial/ethnic minorities does not appear to reflect reduced vulnerability to TEs, with the exception of PTSD among Asians. This highlights the importance of investigating other potential mechanisms underlying racial/ethnic differences in psychopathology.
Context, word, and student predictors in second language vocabulary learning
Authors: MULDER EVELIEN , VAN DE VEN MARCO , SEGERS ELIANE , VERHOEVEN LUDO 
Published: October 2018

ABSTRACTWe examined to what extent the variation in vocabulary learning outcomes (vocabulary knowledge, learning gain, and rate of forgetting) in English as a second language (L2) in context can be predicted from semantic contextual support, word characteristics (cognate status, Levenshtein distance, word frequency, and word length), and student characteristics (prior vocabulary knowledge, reading ability, and exposure to English) in 197 Dutch adolescents. Students were taught cognates, false friends, and control words through judging sentences with varying degrees of semantic contextual support using a pretest/posttest between subjects design. Participants were presented with an English target word and its Dutch translation, followed by an English sentence. They were instructed to judge the plausibility of the sentence. Mixed-efffects models indicated that learning gains were higher for sentences with more semantic contextual support and in students with stronger reading comprehension skills. We were the first to show that Levenshtein distance is an important predictor for L2 vocabulary learning outcomes. Furthermore, more accurate as well as faster learning task performance lead to higher learning outcomes. It can thus be concluded that L2 study materials containing semantically supportive contexts and that focus on words with little L1-L2 overlap are most effective for L2 vocabulary learning.
Domestic entanglements: Family, state, hierarchy, and the Hobbesian state of nature
Authors: Levin Jamie , MacKay Joseph 
Published: October 2018

AbstractThis article revisits the Hobbesian account of the state of nature and the formation of states, attending to Hobbes’s account of the family. Drawing on feminist readings, we find in theLeviathanan account of the family as a natural political community. We contend specifically that a focus on conceptions of family life in theLeviathan, and in works by Hobbes’s early modern peers, points to the role of the family as a site of socialisation in the prelude to early state formation and in the formation of political hierarchies more generally – including, we suggest, the formation of international hierarchies. These accounts have thus far been missing from International Relations theory. Contra conventional IR theoretic readings of theLeviathan, the Hobbesian state of nature contains the seeds of both anarchy and hierarchy, as overlapping social configurations. While anarchy emerges clearly in the famous condition of ‘war of all against all’, hierarchy also exists in Hobbes’s depiction of family life as a naturally occurring proto-state setting. On the basis of this contemporary feminist analysis of a classic text, we consider implications for the emerging ‘new hierarchy studies’ in IR.

Published: October 2018

AbstractThe collimated electron jets ejected from cylindrical plasma are produced in particle-in-cell simulation under the applied longitudinal magnetostatic field and radial electrostatic field, which is a process that can be conveniently performed in a laboratory. We find that the applied magnetostatic field contributes significantly to the jet collimation, whereas the applied electrostatic field plays a vital role in the jet formation. The generation mechanism of collimated jets can be well understood through energy gain of the tagged electrons, and we conclude that the longitudinal momentum of the electrons is converted from the transverse momentum via the transverse-induced magnetic field. It has been found that the ejecting velocity of the jets is close to the speed of light when the applied electrostatic field reaches 3 × 1010 V/m. The present scheme may also give us an insight into the formation of astrophysical jets in celestial bodies.
The Political and Economic Consequences of Nationalist Protest in China: The 2012 Anti-Japanese Demonstrations

AbstractWhat are the consequences of nationalist unrest? This paper utilizes two original datasets, which cover 377 city-level anti-Japanese protests during the 2012 Senkaku/Diaoyu Island crisis and the careers of municipal leaders, to analyse the downstream effects of nationalist unrest at the subnational level. We find both political and economic consequences of China's 2012 protest demonstrations against Japan. Specifically, top Party leaders in cities that saw relatively spontaneous, early protests were less likely to be promoted to higher office, a finding that is consistent with the widely held but rarely tested expectation that social instability is punished in the Chinese Communist Party's cadre evaluation system. We also see a negative effect of nationalist protest on foreign direct investment (FDI) growth at the city level. However, the lower promotion rates associated with relatively spontaneous protests appear to arise through political rather than economic channels. By taking into account data on social unrest in addition to economic performance, these results add to existing evidence that systematic evaluation of leaders’ performance plays a major role in the Chinese political system. These findings also illuminate the dilemma that local leaders face in managing popular nationalism amid shifting national priorities.
Narratives and Pathways towards an Ecological Civilization in Contemporary China
Authors: Geall Sam , Ely Adrian 
Published: October 2018

AbstractSince the United States committed to withdraw from the UN Paris Agreement on climate change, international observers have increasingly asked if China can take the lead instead to raise global ambition in the context of a world leadership vacuum. Given the country's increasing economic and strategic focus on sustainable and low-carbon innovation, China might seem well placed to do so. However, much depends on the direction of governance and reform within China regarding the environment. To better understand how the government is seeking to make progress in these areas, this article explores key political narratives that have underpinned China's policies around sustainable development (kechixu fazhan) and innovation (chuangxin) within the context of broader narratives of reform. Drawing on theoretical insights from work that investigates the role of power in shaping narratives, knowledge and action around specific pathways to sustainability, this article explores the ways in which dominant policy narratives in China might drive particular forms of innovation for sustainability and potentially occlude or constrain others. In particular, we look at ecological civilization (shengtai wenming) as a slogan that has gradually evolved to become an official narrative and is likely to influence pathways to sustainability over the coming years.

Published: October 2018

Differential Global Positioning Systems (DGPS) and the European Geostationary Navigation Overlay Service (EGNOS) are included in a group of supporting systems (Ground-Based Augmentation System (GBAS)/Space-Based Augmentation System (SBAS)) for the American GPS. Their main task is to ensure better positioning characteristics (accuracy, reliability, continuity and availability) compared to GPS. Therefore, they are widely applied wherever GPS failures affect human safety, mainly in aviation, land and marine navigation. The aim of this paper is to assess the predictable positioning accuracy of DGPS and EGNOS receivers using a vessel manoeuvring in the Bay of Gdansk. Two receivers were used in the study: a Simrad MXB5 (DGPS) and a Trimble GA530 (EGNOS), which were simultaneously recording their coordinates. The obtained values were compared with the trajectory computed using a geodetic Global Navigation Satellite System (GNSS) receiver (Trimble R10) connected to a GNSS network, ensuring an accuracy of 2–3 cm (p = 0·95). During a four-hour measurement session, the accuracy statistics of these systems were determined based on around 11,500 positionings. Studies have shown that both positioning systems ensure a similar level of accuracy of their positioning services (approximately 0·5–2 m) and they meet the accuracy requirements set in published standards.
Echocardiographic MRI: an innovative fusion of functional and anatomic assessment strategy for CHD
Authors: Gearhart Addison S. , Raymundo Stephanie A. , Chang Anthony C. 
Published: October 2018

AbstractWe present a pilot case using an innovative fusion of echocardiogram and MRI achieved with a MATLAB-based imaging programme to explore the feasibility of this imaging strategy in the functional and anatomic assessment of a patient with repaired tetralogy of Fallot requiring pulmonary valve intervention. Echocardiogram and MRI neutralises the disadvantages and limitations of each individual imaging modality and yields important anatomic and haemodynamic information crucial to the treatment decision-making process. Future image fusion strategies can apply to three-dimensional images and image-directed therapy for CHD.

Published: October 2018

AbstractIntroductionA crucial component of a hospital’s disaster plan is an efficient staff recall communication method. Many hospitals use a “calling tree” protocol to contact staff members and recall them to work. Alternative staff recall methods have been proposed and explored.MethodsAn unannounced, multidisciplinary, randomized emergency department (ED) staff recall drill was conducted at night - when there is the greatest need for back-up personnel and staff is most difficult to reach. The drill was performed on December 14, 2017 at 4:00am and involved ED staff members from three hospitals which are all part of the McGill University Health Centre (MUHC; Montreal, Quebec, Canada). Three tools were compared: manual phone tree, instant messaging application (IMA), and custom-made hospital Short Message Service (SMS) system. The key outcome measures were proportion of responses at 45 minutes and median response time.ResultsOne-hundred thirty-two participants were recruited. There were 44 participants in each group after randomization. In the manual phone tree group, 18 (41%) responded within 45 minutes. In the IMA group, 11 participants (25%) responded in the first 45 minutes. In the SMS group, seven participants responded in the first 45 minutes (16%). Manual phone tree was significantly better than SMS with an effect size of 25% (95% confidence interval for effect: 4.6% to 45.0%; P=.018). Conversely, there was no significant difference between manual phone tree and IMA with an effect size of 16% (95% confidence interval for effect: −5.7% to 38.0%; P=.17) There was a statistically significant difference in the median response time between the three groups with the phone tree group presenting the lowest median response time (8.5 minutes; range: 2.0 to 8.5 minutes; P=.000006).Conclusion:Both the phone tree and IMA groups had a significantly higher response rate than the SMS group. There was no significant difference between the proportion of responses at 45 minutes in the phone tree and the IMA arms. This study suggests that an IMA may be a viable alternative to the traditional phone tree method. Limitations of the study include volunteer bias and the fact that there was only one communication drill, which did not allow staff members randomized to the IMA and SMS groups to fully get familiar with the new staff recall methods.HomierV, HamadR, LarocqueJ, ChasséP, KhalilE, FrancJM.A randomized trial comparing telephone tree, text messaging, and instant messaging app for emergency department staff recall for disaster response.

Published: October 2018

AbstractBackgroundThe contamination of the environment, ambulance equipment, and staff hands consequently are major factors which create nosocomial infections in emergency patients. The contamination of equipment and devices plays an important role in nosocomial infections.ObjectivesThe aim of this study was to determine the effectiveness of a disinfectant on the rate of microbial contamination of ambulances in Qom Emergency Medical Services (EMS), Qom, Iran.MethodsThis is a quasi-experimental study with a before-after design in order to determine microbial contaminations at the rear and front cabin of ambulances, as well as medical equipment being utilized in Qom EMS. Saya sept-HP-2% solution was used for disinfection. Bacteriological standard methods were used to identify the contaminations.ResultsThe contamination rates before and after use of disinfection solution were 52% and eight percent, respectively. Coagulase-negative staphylococci were the most commonly isolated bacterial agent from the equipment (53%). In all equipment, the contamination level has shown a significant reduction after applying disinfectant.Conclusions:In spite of the fact that the rate of infection from ambulance equipment is high, the results showed that the use of the suitable disinfectant had an effective role in the reduction of bacteria.FarhadlooR, Goodarzi FarJ, AzadehMR, ShamsS, Parvaresh-MasoudM.Evaluation of bacterial contamination on prehospital ambulances before and after disinfection.

Published: October 2018

AbstractObjectiveThis study aims at establishing the self-leadership development model (SLM) of China Emergency Medical Team (CEMT) members as a supplement to current selection standards of CEMT members.MethodsRaw dataset was obtained through two ways: in-depth interviews and documentary materials (memoirs and articles). The in-depth interviews were conducted with a purposive sample of 12 CEMT members, all of whom have participated in multiple disaster relief activities and have been CEMT members for more than two years. This paper followed a grounded theory methodology dealing with all data.ResultsBased on tasks, the SLM-CEMT consists of three basic parts: (1) making plans; (2) action; and (3) outcomes. Different parts involve various self-leadership strategies, of which five are the original dimensions of previous research (goal-setting, visualizing successful performance, self-talk, self-reward, and self-correcting feedback) and three are new dimensions (role clarity, self-initiative, and self-vigilance).Conclusions:The SLM-CEMT, with the three new parts, provides a new look at screening CEMT members as well as pondering on future research. Based on the SLM-CEMT, administrators could screen more qualified CEMT members. For the limitations, future work will be on the generalization and confirmation of this model.HaoX,LiX,ZhengJ.Screening China Emergency Medical Team (CEMT) members: a self-leadership perspective.Prehosp Disaster Med.2018;33(6):596–601.
