Published: April 2021

ABSTRACT:Background:Prehospital delays are a major obstacle to timely reperfusion therapy in acute ischemic stroke. Stroke sign recognition, however, remains poor in the community. We present an analysis of repeated surveys to assess the impact of Face, Arm, Speech, Time (FAST) public awareness campaigns on stroke knowledge.Methods:Four cross-sectional surveys were conducted between July 2016 and January 2019 in the province of Quebec, Canada (n = 2,451). Knowledge of FAST stroke signs (face drooping, arm weakness and speech difficulties) was assessed with open-ended questions. A bilingual English/French FAST public awareness campaign preceded survey waves 1–3 and two campaigns preceded wave 4. We used multivariable ordinal regression models weighted for age and sex to assess FAST stroke sign knowledge.Results:We observed an overall significant improvement of 26% in FAST stroke sign knowledge between survey waves 1 and 4 (odds ratio [OR] = 1.26; 95% CI: 1.02, 1.55; p = 0.035). After the last campaign, however, 30.5% (95% CI: 27.5, 33.6) of people were still unable to name a single FAST sign. Factors associated with worse performance were male sex (OR = 0.68; 95% CI: 0.53, 0.86; p = 0.002) and retirement (OR = 0.54; 95% CI: 0.35, 0.83; p = 0.005). People with lower household income and education had a tendency towards worse stroke sign knowledge and were significantly less aware of the FAST campaigns.Conclusions:Knowledge of FAST stroke signs in the general population improved after multiple public awareness campaigns, although it remained low overall. Future FAST campaigns should especially target men, retired people and individuals with a lower socioeconomic status.

ABSTRACT:Levodopa-carbidopa intestinal gel infusion (LCIG) is an established therapy for advanced Parkinson disease (PD), resulting in a significant improvement of quality of life. With increased LCIG adoption worldwide, potential complications due to abnormal vitamin absorption or metabolism have been reported in these patients. Neurologists are unfamiliar with vitamins physiology and pathophysiological mechanisms in case of their deficiency. Unfortunately, clinical and laboratory guidelines related to vitamin monitoring and supplementation in the context of treatment with LCIG are not available. We herein summarize the current knowledge on three vitamins that are reduced with LCIG therapy reporting on their physiology, laboratory testing, and clinical impact of their deficiency/excess. In addition, we proposed an opinion-based recommendation for clinicians treating LCIG patients. Patients and caregivers should be informed about the risk of vitamin deficiency. Vitamin B12, homocysteine, and methylmalonic acid (MMA) should be tested before starting LCIG, six months after and once/year thereafter. Vitamin B6 and folate testing is not universally available but it should be considered if homocysteine is elevated but MMA and/or total vitamin B12 are normal. Prophylaxis of vitamin deficiency should be started as soon as LCIG is implemented, possibly even before. Dietary recommendations are enough in most patients although a subgroup of patients is at higher risk and should receive Vitamin B12 regularly and cycles of B6. Finally, once diagnosed a vitamin deficiency should be readily treated and accompanied by clinical and laboratory monitoring. Resistant cases should receive non-oral routes of administration and possibly discontinue LCIG, even temporarily.

AbstractInvestment in family planning (FP) provides returns through a lifetime. Global evidence shows that FP is the second-best buy in terms of return on investment after liberalizing trade. In this study, we estimate the cumulative benefits of FP investments for India from 1991 to 2016 and project them up to 2061 with four scenarios of fertility levels. The findings suggest that India will have greater elasticity of FP investments to lifetime economic returns compared to the world average (cost–revenue ratio of 1:120). We have taken four scenarios for the goalpost, viz., 2.1, 1.8, 1.6, and 1.4. Although different scenarios of total fertility rate (TFR) levels at the goalpost (i.e., the year 2061) offer varied lifetime returns from FP, scenario TFR < 1.8 will be counterproductive and will reduce the potential benefits. With a comprehensive approach, if the country focuses more on improving the quality of FP services and on reducing the unmet need for FP to enhance reproductive health care and expand maximum opportunities for education and employment for both women and men, it can improve its potential to reap more benefits.
The first Early Ordovician graptolites and marine incursions in eastern Alborz, Iran

Published: April 2021

AbstractGraptolites have been collected from sections through Lower Ordovician strata in northern Iran. At the Saluk Mountains, in the Kopet–Dagh region, mudrocks yielded fragmentary tubaria ofRhabdinoporasp. cf.R. flabelliformis, indicating the presence of lower Tremadocian strata there; stratigraphically, they lie between two limestone beds with the euconodontCordylodus lindstromi. At Simeh–Kuh in the eastern Alborz Mountains (Semnan Province), upper Tremadocian – lower Floian strata include laminated dark mudstones that contain restricted graptolite faunas, mainly of small declined didymograptids; these are thought to represent incursions of plankton during periods of marine highstands. The lower major flooding surface in Simeh–Kuh coincides with an invasion of the graptolite biofacies and an incursion ofHunnegraptus? sp.; the second major flooding surface is associated with an incursion ofBaltograptus geometricus. They were most probably synchronous with those in the lower part of theHunnegraptus copiosusBiozone and at the base of theCymatograptus protobalticusBiozone in the of the Tøyen Shale Formation succession of Västergötland, Scandinavia, suggesting that observed characters of sedimentation were eustatically controlled.
Mass Observation, Apathy, and Electoral Politics in England, 1937–1950
Authors: Thackeray David 
Published: April 2021

AbstractWhile various historians use Mass Observation sources to study popular engagement with politics in the 1940s, they tend to rely on file reports summarizing research or the writings of the national panel, which paid limited attention to how the public engaged with key aspects of electioneering. By contrast, we re-examine Mass Observation's various election surveys to explore people's assumptions about how election campaigns should be conducted, the qualities looked for in political parties, and their reflections on the records of governments. Our conclusions shed light on the transformation of British public politics after 1918. During the interwar years it became common thinking to assume that parties would centre their campaigning around a detailed programme for government. Whereas Mass Observation's employees often claimed that much of the public was apathetic about politics, a reanalysis of the survey results indicates that many people were eager to be seen to be able to offer a considered assessment of the veracity of the competing parties’ promises. Mass Observation's election studies were criticized for their supposed amateurism. However, they offer richer insights into how the public engaged with party programmes than the quantitative surveys that came to dominate election studies in the 1950s and beyond.
Usurpers of Technology: Train Robbery and Theft in Egypt, 1876–1904
Authors: Li Xiaoyue 
Published: April 2021

AbstractThis article examines banditry, embezzlement, and other insider crimes along Egyptian railway lines during a period when British officials exerted centralized control over the Egyptian railway and financial austerity had a negative impact on the rail sector. By exploring the motives and tactics of railway crimes, I posit that criminals, by making claims on and use of the technology outside the purview of state regulations, expressed their heterogeneous desires to redistribute social wealth, repurpose the technological promise of modern railways, and confound intentions of colonial governance. Using new archival materials, this article utilizes a bottom-up approach to examine grassroots activism, everyday knowledge, informal networks, and the social mores and norms that criminals harnessed to discern infrastructural vulnerabilities and elude surveillance from the colonial state. Ultimately, I contend that criminal acts uncovered social crises otherwise hidden under the shadow of the exterior prosperity and stability of late 19th-century Egypt.
Conflict, Cooperation, and Delegated Diplomacy
Authors: Malis Matt 
Published: April 2021

AbstractDoes diplomacy affect the prospects of international conflict and cooperation? Systematic empirical assessment has been hindered by the inferential challenges of separating diplomacy from the distribution of power and interests that underlies its conduct. This paper addresses the question of diplomacy's efficacy by examining the intragovernmental politics of US foreign policy, and the varying influence of diplomatic personnel in the policy process. I claim that diplomats hold the strongest preferences for cooperative relations with their host countries, relative to other participants in the foreign policy process. They also exert substantial influence over the formation and implementation of US policies toward their host countries but their influence is intermittently weakened by the short-term shock of an ambassadorial turnover. As a result, when ambassadors are removed from post, diplomacy is more likely to be eschewed for more conflictual means of settling international disagreements, and opportunities for economic exchange are less likely to be realized. I test this theory using newly collected data on US diplomatic representation, for the global sample of countries from 1960 through 2014. To address concerns of diplomatic staffing being endogenous to political interests, I leverage a natural experiment arising from the State Department's three-year ambassadorial rotation system. The turnover of a US ambassador causes a decrease in US exports to the country experiencing the turnover, and heightens the risk of onset of a militarized dispute between that country and the US. These findings point to bureaucratic delegation as an important but overlooked determinant of macro-level international outcomes.
An American Call Is Worth More Than a European Call: The Value of American Exercise When the Market Is Not Perfectly Liquid
Authors: Figlewski Stephen 
Published: April 2021

AbstractTheory says an American call should never be exercised early, except possibly just before an ex-dividend date. But the best market bid is regularly lower than the intrinsic value for in-the-money short-maturity options. An American option can always be exercised to recover the intrinsic value, whereas selling a European call in the market may return considerably less. The article derives the liquidity value of American exercise in closed form as a function of the bid–ask spread and shows empirically that it is of comparable magnitude to, and often greater than, the theoretical value of American exercise to collect a dividend.
Computational fluid dynamic modelling of maxillary sinus irrigation after maxillary antrostomy and modified endoscopic medial maxillectomy

Published: April 2021

AbstractObjectiveFor recalcitrant chronic maxillary sinusitis, modified endoscopic medial maxillectomy has been shown to be clinically beneficial after failed maxillary antrostomy as endoscopic medial maxillectomy may offer improved topical therapy delivery. This study compared irrigation patterns after maxillary antrostomy versus endoscopic medial maxillectomy, using computational fluid dynamic modelling.Case reportA 54-year-old female with left chronic maxillary sinusitis underwent maxillary antrostomy, followed by endoscopic medial maxillectomy. Computational fluid dynamic models were created after each surgery and used to simulate irrigations.ResultsAfter maxillary antrostomy, irrigation penetrated the maxillary sinus at 0.5 seconds, initially contacting the posterior wall. The maxillary sinus was half-filled at 2 seconds, and completely filled at 4 seconds. After endoscopic medial maxillectomy, irrigation penetrated the maxillary sinus at 0.5 seconds and immediately contacted all maxillary sinus walls. The maxillary sinus was completely filled by 2 seconds.ConclusionComputational fluid dynamic modelling demonstrated that endoscopic medial maxillectomy allowed faster, more forceful irrigation to all maxillary sinus walls compared with maxillary antrostomy.
Using local knowledge and camera traps to investigate occurrence and habitat preference of an Endangered primate: the endemic dryas monkey in the Democratic Republic of the Congo

Published: April 2021

AbstractThe Endangered dryas monkey Cercopithecus dryas, endemic to the Democratic Republic of the Congo, is one of Africa's most enigmatic primates. The discovery of a dryas monkey killed by a hunter in the buffer zone of Lomami National Park in 2014 prompted field research on the species’ distribution, habitat use and stratum preference. We used local knowledge to determine the distribution of this species and to select sites for camera-trap surveys in Lomami National Park and its buffer zone. We employed a multi-strata (0–29 m) camera-trap placement technique to determine habitat use at Camp Bartho in Lomami National Park and Bafundo Forest in the Park's buffer zone. We confirmed the occurrence of the dryas monkey at seven locations over a total area of 3,453 km2, in both the Park and its buffer zone. Dryas monkeys were detected most frequently (2.22 events/100 trap-days) in disturbed areas of Bafundo Forest and less in mature forest in Camp Bartho (0.82 events/100 trap-days). Dryas monkeys appear to prefer structurally complex understories and forest edges. We found that camera traps at 2–10 m above ground over at least 365 trap-days are required to determine if the species is present. We recommend utilizing local knowledge and using this species-specific camera-trap method in other areas of the central Congo basin to determine the wider distribution of the dryas monkey.

AbstractBackgroundGiven the widespread nature and clinical consequences of self-harm and suicidal ideation among adolescents, establishing the efficacy of developmentally appropriate treatments that reduce both self-harm and suicidal ideation in the context of broader adolescent psychopathology is critical.MethodsWe conducted a systematic review and meta-analysis of the Dialectical Behaviour Therapy for Adolescents (DBT-A) literature on treating self-injury in adolescents (12–19 years). We searched for eligible trials and treatment evaluations published prior to July 2020 in MEDLINE/PubMed, Scopus, Google Scholar, EMBASE, and the Cochrane Library databases for clinical trials. Twenty-one studies were identified [five randomized-controlled trials (RCTs), three controlled clinical trials (CCTs), and 13 pre-post evaluations]. We extracted data for predefined primary (self-harm, suicidal ideation) and secondary outcomes (borderline personality symptoms; BPD) and calculated treatment effects for RCTs/CCTs and pre-post evaluations. This meta-analysis was pre-registered with OSF: osf.io/v83e7.ResultsOverall, the studies comprised 1673 adolescents. Compared to control groups, DBT-A showed small to moderate effects for reducing self-harm (g= −0.44; 95% CI −0.81 to −0.07) and suicidal ideation (g= −0.31, 95% CI −0.52 to −0.09). Pre-post evaluations suggested large effects for all outcomes (self-harm:g= −0.98, 95% CI −1.15 to −0.81; suicidal ideation:g= −1.16, 95% CI −1.51 to −0.80; BPD symptoms:g= −0.97, 95% CI −1.31 to −0.63).ConclusionsDBT-A appears to be a valuable treatment in reducing both adolescent self-harm and suicidal ideation. However, evidence that DBT-A reduces BPD symptoms was only found in pre-post evaluations.
Understanding older adults’ use of social technology and the factors influencing use

Published: April 2021

AbstractHaving access and skills to use social technology,i.e.social internet use, social media and social applications, are considered as being vital to online social connection. Whilst evidence exists around facilitators and barriers to general technology use, evidence is limited with regards to the motivators, skills and tangible offline benefits older technology users experience with social technology. Therefore, this study used a qualitative, exploratory method to understand older adults’ experiences of using social technology to connect with others. Semi-structured interviews were conducted with 20 older adults (65+ years) across England, Scotland and Wales. Despite having access to social technology for social connection, and using this technology regularly, multiple barriers impacted motivators and skills for use, namely perceived self-efficacy and fear, the culture of online communication, absence of social capital and physical functioning. Some of these barriers of social technology use are reminiscent of barriers of wider technology use and emphasise the importance of addressing these barriers for digital exclusion, as well as social connection. However, some of these barriers were specific to social technology use and should be considered when providing guidance or interventions to increase older adults’ online social connection. Social connection was a clear tangible outcome to social technology use, and individuals discussed the benefits of using social technology, particularly visual communication tools, for online connection.
Claudia Jones, International Thinker
Authors: Dunstan Sarah , Owens Patricia 
Published: April 2021

AbstractThis article analyses the early international thought of Trinidad-born Marxist journalist Claudia Jones. We focus on a neglected aspect of Jones's intellectual production in the United States: her interrogation of geopolitics in her Weekly Review articles in the early 1940s. We situate Jones in relation to the contemporary popularization of geopolitical thought in this period, reading her alongside another neglected figure in histories of international thought, the African American geopolitical scholar and diplomatic historian Merze Tate. Jones read together the geopolitical, class, racialized, and anticolonial implications of the expanding Nazi empire, positioning her at the forefront of Marxist theoretical innovation in this period. Moving beyond studies of canonical texts and white male thinkers in international intellectual history, we build on black women's intellectual history to center a black working-class woman's popular theorizing of international relations.
“The President's Prerogative”? The Cabinet Appointment Process in Ghana and the Implications for Gender Parity
Authors: Bauer Gretchen , Darkwah Akosua K. 
Published: April 2021

AbstractThis article seeks to understand why Ghana, unlike several other African countries, has seen relatively few women appointed as ministers to the cabinet since the transition to democracy. We draw on Annesley, Beckwith, and Franceschet's 2019 bookCabinets,Ministers and Gender, which provides an in-depth analysis of the cabinet appointment process in seven democracies (but no African cases) and demonstrates that the cabinet appointment process is gendered—that is, men and women have different (and unequal) opportunities to be appointed as cabinet ministers. This article covers Ghana's Fourth Republic, during which women's presence in cabinets has increased slowly but steadily. We rely on media reports from five recent presidential administrations and semistructured, in-depth interviews with selected informants, as well as other primary and secondary sources. We find that while Ghana has a fairly empowered president who could appoint a gender parity cabinet, the formal and informal rules governing the selection of cabinet ministers—for example, those related to regional balance and “minister MPs”—work against more women in the cabinet.
Evolution of imidazolinone-resistant weedy rice in Malaysia: the current status

Published: April 2021

AbstractWeedy rice (Oryza sativa f. spontanea or O. sativa complex) has become a severe threat to Malaysian rice (Oryza sativa L.) granaries after the direct-seeding method of rice cultivation was introduced in the late 1980s. Since then, researchers have studied the biology and ecology of weedy rice and espoused the evolutionary theory of the origin of Malaysian weedy rice. This review paper aimed to synthesize the body of knowledge about weedy rice and the evolution of herbicide-resistant (HR) weedy rice in Malaysia. The imidazolinone (IMI) herbicide component of the Clearfield® Production System (CPS) rice package is among the most effective tools for weedy rice control. However, dependence solely on this technology and farmers’ ignorance about the appropriate use of IMI herbicides with the CPS rice package have resulted in the evolution of IMI-resistant (IMI-R) weedy rice. This has reduced the efficacy of IMI herbicides on weedy rice, ultimately nullifying the benefit of CPS rice in affected fields. At present, it is assumed that IMI-R weedy rice populations are widely distributed across the rice granaries in Malaysia. Therefore, it is important that integrated management measures be adopted comprehensively by Malaysian rice growers to curb the spread of IMI-R weedy rice problem in Malaysia, especially in fields planted with CPS rice. This review focuses on the biology of Malaysian weedy rice, the history of the establishment of weedy rice in Malaysian rice fields, the impact of HR rice technology on the evolution of IMI-R weedy rice in Malaysia, the distribution of resistant weedy rice populations across Peninsular Malaysia rice granaries, the weedy rice resistance mechanisms, and weedy rice management. The synthesis of all this information is helpful to researchers, policy makers, the private agricultural industry, advisers to farmers, and proactive farmers themselves with the goal of working toward sustainable rice production.
