Volterra Centennial Meetings - Invited talks given by Christopher Baker at Arlington & Tempe
No full textJune 1996 saw two meetings to mark the centennial of the mathematical work of Vito Volterra, the first being held at the University of Texas at Arlington (organised by Professors Corduneanu and Kanner) and the second at the State University of Arizona at Tempe. In invited talks at each meeting, the first-named author presented joint work that follows, in chronological sequence, in this technical report. Christopher T H Baker & Arslang Tang 2 GENERALIZED HALANAY INEQUALITIES FOR VOLTERRA FUNCTIONAL DIFFERENTIAL EQUATIONS AND DISCRETIZED VERSIONS CHRISTOPHER T.H. BAKER 1 & ARSALANG TANG 2 Department of Pure and Applied Mathematics, The Victoria University of Manchester, England Abstract. Halanay's inequality provides a decreasing bound on a function satisfying a delay-differential inequality, subject to certain conditions, and it has been used by Halanay to analyze asymptotic stability of the zero solution of a certain delay-differential equations with fixed lag.

The Global Cohort of Doctoral Students: Building Shared Global Health Research Capacity in High-Income and Low- and Middle-Income Countries
No full textDoctoral students in high- and low-income countries pursuing careers in global health face gaps in their training that could be readily filled through structured peer-learning activities with students based at partnering institutions in complimentary settings. We share lessons learned from the Global Cohort of Doctoral Students, a community of doctoral students based at the Harvard T. H. Chan School of Public Health, Haramaya University. University of Gondar, University of Botswana, and University of Rwanda College of Medicine and Health Sciences. Students in the Global Cohort program engage in collaborative research, forums for constructive feedback, and professional development activities. We describe the motivation for the program, core activities, and early successes.This work was funded by the Rose Traveling Fellowship and Deborah Rose Service Learning Fellowship at the Harvard T. H. Chan School of Public Health. The funding sources had no role in the writing of the manuscript or decision to submit it for publication.Iyer, HS (corresponding author), Harvard TH Chan Sch Publ Hlth, Dept Epidemiol, Boston, MA 02115 USA.

Published by Informa UK Limited, trading as Taylor & Francis Group. ‘Founders’ is an intermittent series of short, critical appreciations of scholars, researchers and others whose work and ideas, mainly in Britain, have made particularly sweeping, influential and foundational contributions to the development of historically- and archaeologically-informed landscape studies. This latest addition to the series concerns Christopher Taylor, whose death on 28th May 2021 was noted in the Landscapes editorial in issue 21.2
Hypertrophic cardiomyopathy with cardiac rupture and tamponade caused by congenital disorder of glycosylation type Ia
No full textHypertrophic cardiomyopathy (HCM) is a rare presenting feature of congenital disorder of glycosylation type Ia (CDG-Ia). We report two female siblings with CDG-Ia and cardiomyopathy. Patient no. 1 died at 12 days of age from cardiac rupture and tamponade, which has not previously been reported in CDG-Ia. The second patient died at 2 months of age from HCM. The severe cardiac manifestations seen in our patients emphasize the importance of early cardiac assessment in all patients with CDG-Ia.Laura I. Rudaks, Chad Andersen, T. Y.

The Etiology and Treatment of Anemia
No full textAnemia is a significant global health challenge. While the subject of anemia has been well-studied, critical questions regarding its causes and treatment remain.
Chapter 1 investigates the optimal schedule, duration, dose, and co-supplementation regimen for iron supplementation as a treatment of anemia among children. A systematic review and meta-analysis of randomized controlled trials was conducted. A total of 123 eligible trials were identified. Frequent (3-7/week) and intermittent (1-2/week) iron regimens were similarly effective at increasing hemoglobin and decreasing anemia, iron deficiency, and iron deficiency anemia (p-heterogeneity>0.05). Varying durations of supplementation showed similar benefits after controlling for baseline anemia status, except for serum ferritin, which showed larger increases with longer duration of iron (p=0.04). Moderate- and high-dose supplements were more effective than low-dose supplements at improving hemoglobin (p=0.03) and ferritin (p=0.003). Co-supplementation of iron with zinc or vitamin A modestly attenuated impacts for anemia (p=0.048) and hemoglobin (p=0.03), respectively, although benefits remained even in co-supplemented groups.
In Chapter 2, the risks and benefits of iron supplementation among HIV-infected children are examined. A prospective cohort study of 4,229 children were observed for a mean follow-up of 2.9 years. After adjustment for time-varying clinical covariates, time-varying iron supplementation was associated with a 2.87 times higher hazard rate of mortality (95% CI: 1.70, 4.87) and a 1.48 times higher hazard rate of HIV disease stage progression (95% CI: 1.10, 1.98). Iron supplementation was also associated with a lower rate of anemia persistence (HR=0.47; 95% CI: 0.37-0.61). No differences in the association between iron supplementation and clinical outcomes were observed by ART or anemia status.
Chapter 3 quantifies the proportion of anemia cases attributable to selected nutritional, infectious disease, and other risk factors. A population-based cross-sectional study of women, men, and children was conducted. Low serum ferritin contributed to 11% (-1, 22) of anemia cases among women, 9% (0, 17) among men, and 19% (3, 33) among children. The proportion of anemia attributable to low serum folate was estimated at 25% (4, 40) among women and 28 (11, 42) among men. Inflammation and malaria were responsible less than one in ten anemia cases
Exploiting Knowledge across Networks through Reputation Management.
No full textThe emerging paradigm of network competition is increasingly in evidence across many industrial sectors and provides further support for the idea that ‘supply chains compete, not companies’. It can be argued that network competition requires a much greater focus on managing the interfaces that connect the individual players in that network and exchanging and leveraging knowledge across the network. This paper sets out to establish a framework whereby the critical interfaces and the knowledge sharing benefits can be identified and how the strength of the relationships at those interfaces can become the basis for building organisational reputation and create an environment more conducive to co-operation and knowledge sharing. Finally, the paper analyses the potential impact of reputational risks in influencing the perception of stakeholders about the organisation.
Whilst the idea of value-adding networks based on closely connected providers of capabilities and resources is appealing, it should be recognised that, if not properly managed, the actions of the stakeholders in those networks can impact the risk profile of the business significantly—particularly reputational risk. The more that organisations become part of complex global networks, the more dependent they become upon the other network members for knowledge and other resources. Because of this dependency there is always the danger that the reputation of the focal firm can be damaged by the actions of other network members, hence reducing the likelihood of future collaborative working and knowledge exploitation.
Using examples drawn from a variety of industries, the paper highlights the potential for reputational risk if the critical network interfaces are not closely managed. It will be argued that by actively managing relationships with stakeholders in the network the risk to the organisation's reputation can be mitigated and the sharing of knowledge simultaneously enhanced
