Engineering Reuse for On-board Embedded Real-Time Systems
No full textThe dimensions of concern to ambitious reuse initiatives largely exceed the provision of desired functionalities. A domain-specific blend of functional, technical and quality considerations determines the reuse potential of software reuse assets. In a recent project we realized considerable reuse dividends from coupling the definition of a reference software architecture and of an associated set of standard interfaces with the selection of a powerful computational model equipped with reuse-geared enabling technology. In this paper we present our engineering approach to the project and show how it earned us a good balance between the preservation of predictability and scalability and the maximization of the reuse objective
Using the Ravenscar Profile for Space Applications: the OBOSS Case
No full textThe Ravenscar Profile emerged in 1997 as a most promising approach to bringing mature, predictable and efficient concurrency into real-time systems with integrity requirements. One of the crucial questions that have arisen since is whether the expressive power of the profile would be truly sufficient for the effective construction of such systems. This paper provides positive evidence to this effect by discussing the merit of the Ravenscar compliant architecture of a reuse library that supports the construction of on-board embedded real-time systems of the new generation. This paper argues that the notions of the profile especially contributed to increase the maturity of the reuse product. As true object orientation is the next frontier of the product, this paper also reflects on the importance of integrating the profile with suitable flavours of object orientation
A Case Study in the Reuse of On-board Embedded Real-Time Software
No full textThe rise of the ‘cheaper, faster, better’ mission paradigm increasingly challenges the industrial development of satellite systems. The novel paradigm will have a profound impact on the production of the real-time software embedded on board new-generation systems. This paper discusses how software reuse may fit in the rising development scenario and how reuse interacts with other important players in the picture, especially the software process model and the on-board software architecture
Reference guide of physical activity programs for older adults; a resource for planning intervention
No full text"Division of Diabetes Translation's (DDT's) mission is to eliminate the preventable burden of diabetes through leadership, research, programs, and polices that translate science into practice. In 2001, staff at DDT wanted to explore the impact of diabetes on aging-related outcomes. We assembled a small panel of experts in aging to explore the diabetes-and-aging issue. This group produced a white paper focused on four areas: surveillance, applied public health research, programs, and policy change and development. From this initial effort, the DDT formed the Diabetes and Aging Work Group (DAWG) to highlight the health issues of older adults with diabetes. In addition to conducting scientific research and communications, the DAWG chose one programmatic focus: preserving physical function in older adults. To further that end, this Reference Guide of Physical Activity Programs for Older Adults: A Resource for Planning Interventions was created as a programmatic tool." - p. vSusana A. Moran, Carl J.

Mobilizing in uncertainty: collective identities and war in Abkhazia
No full textIn this reflection, Anastasia Shesterinina introduces her new book, Mobilizing in Uncertainty: Collective Identities and War in Abkhazia (Cornell University Press, 2021). We invited Nina Caspersen at the University of York, Jesse Driscoll at the University of California, San Diego, and Edward Schatz at the University of Toronto to comment on the book. Their commentaries are followed by a response from the author
Haemostatic parameters and lifestyle factors in elderly men in Italy and The Netherlands
No full textHaemostatic parameters and lifestyle factors in elderly men in Italy and The Netherlands. Bijnen FC, Feskens EJ, Giampaoli S, Menotti A, Fidanza F, Hornstra G, Caspersen CJ, Mosterd WL, Kromhout D. Department of Medical Physiology and Sports Medicine, Utrecht University, The Netherlands. The association between plasma fibrinogen, factor VII, factor X, activated partial thromboplastin time, antithrombin III and the lifestyle factors cigarette smoking, alcohol use, fat intake and physical activity was assessed in 802 men aged 70-90 years in Zutphen (The Netherlands), Montegiorgio and Crevalcore (Italy). Smoking was positively associated with fibrinogen, also after adjustment for other lifestyle factors, age, use of anticoagulants and aspirin like drugs, body mass index, and history of myocardial infarction. Alcohol use was associated with increased levels of factor X and decreased levels of antithrombin III. Fat intake was positively associated with antithrombin III. Between cohorts, considerable differences were observed in levels of haemostatic parameters and the lifestyle factors. Compared to the mediterranean cohorts the Zutphen cohort showed the highest levels of fibrinogen and factor VII. Differences in lifestyle factors could, however, not explain differences between cohorts in levels of any of the haemostatic parameters, despite the observed associations between lifestyle factors and haemostatic parameters

Research priorities for child and adolescent physical activity and sedentary behaviours : an international perspective using a twin-panel Delphi procedure
No full textBACKGROUND: The quantity and quality of studies in child and adolescent physical activity and sedentary behaviour have rapidly increased, but research directions are often pursued in a reactive and uncoordinated manner. AIM:To arrive at an international consensus on research priorities in the area of child and adolescent physical activity and sedentary behaviour. METHODS:Two independent panels, each consisting of 12 experts, undertook three rounds of a Delphi methodology. The Delphi methodology required experts to anonymously answer questions put forward by the researchers with feedback provided between each round. RESULTS:The primary outcome of the study was a ranked set of 29 research priorities that aimed to be applicable for the next 10years. The top three ranked priorities were: developing effective and sustainable interventions to increase children's physical activity long-term; policy and/or environmental change and their influence on children's physical activity and sedentary behaviour; and prospective, longitudinal studies of the independent effects of physical activity and sedentary behaviour on health. CONCLUSIONS:These research priorities can help to guide decisions on future research directions
