Generating systems from multiple sketched models

Diagrams are often used to model complex systems: in many cases several different types of diagrams are used to model different aspects of the system. These diagrams, perhaps from multiple stakeholders of different specialties, must be combined to achieve a full abstract representation of the system. Many CAD tools offer multi-diagram integration; however, sketch-based diagramming tools are yet to tackle this difficult integration problem. We extend the diagram sketching tool InkKit to combine software engineering sketches of different types. Our extensions support software design processes by providing a sketch-based approach that allows the iterative creation of multiple outputs interacting with one another from the inter-linked models. We demonstrate that InkKit can generate a functional system consisting of a user interface with processes to submit and retrieve data from a database from sketched user interfaces designs and sketched entity relationship diagrams.     

Using the community health assessment to screen for continued driving

This project used the interRAI based, community health assessment (CHA) to develop a model for identifying current elder drivers whose driving behavior should be reviewed. The assessments were completed by independent housing sites in COLLAGE, a non-profit, national senior housing consortium. Secondary analysis of data drawn from older adults in COLLAGE sites in the United States was conducted using a baseline assessment with 8042 subjects and an annual follow-up assessment with 3840 subjects. Logistic regression was used to develop a Driving Review Index (DRI) based on the most useful items from among the many measures available in the CHA assessment. Thirteen items were identified by the logistic regression to predict drivers whose driving behavior was questioned by others. In particular, three variables reference compromised decision-making abilities: general daily decisions, a recent decline in ability to make daily decisions, and ability to manage medications. Two additional measures assess cognitive status: short-term memory problem and a diagnosis of non-Alzheimers dementia. Functional measures reflect restrictions and general frailty, including receiving help in transportation, use of a locomotion appliance, having an unsteady gait, fatigue, and not going out on most days. The final three clinical measures reflect compromised vision, little interest or pleasure in things normally enjoyed, and diarrhea. The DRI focuses the review process on drivers with multiple cognitive and functional problems, including a significant segment of potentially troubled drivers who had not yet been publicly identified by others. There is a need for simple and quickly identified screening tools to identify those older adults whose driving should be reviewed. The DRI, based on the interRAI CHA, fills this void. Assessment at the individual level needs to be part of the backdrop of science as society seeks to target policy to identify high risk drivers instead of simply age-based testing.     

Chronic growth faltering amongst a birth cohort of Indian children begins prior to weaning and is highly prevalent at three years of age

Background  

Poor growth of children in developing countries is a major public health problem associated with mortality, morbidity and developmental delay. We describe growth up to three years of age and investigate factors related to stunting (low height-for-age) at three years of age in a birth cohort from an urban slum.     

Effects of stimulation on embryonic activity in the chick.

Studied the effects of stimulation on the stereotyped and coordinated movements in the chick (Rhode Island Red/Light Sussex hybrids) embryo using the type of stimulation (regular loud clicks) known to accelerate development and the time of hatching. The number of coordinated movements, the amount and approximate size of all activity, heart rates and, in 20-day embryos, respiration rates were assessed during 15-min control, stimulation, and no stimulation periods. Results show an increase in the number of coordinated movements, but not their size, and some changes in the heart and respiration rates after the onset of stimulation. Effects occurred mostly after several minutes' delay. It is suggested that this delay may be connected with the reciprocal relationship between the coordinated movements and random motility in that the former may be triggered more readily at times when the latter are suppressed.

The professional psychologist as evaluator in a community agency setting.

Describes a process evaluation of an industrial work unit for persons with disabilities and comments on the role of the psychologist as evaluator in an agency of this type. The relationship of process evaluation to other aspects of evaluation is discussed, and reasons are offered for establishing aims before embarking on an outcome evaluation. Suggestions are offered for ways of using ranked aims in every phase of the evaluation, and steps to facilitate the implementation of evaluation results are outlined.

Actinomycetes in relation to taste and odour in drinking water: myths, tenets and truths

Actinomycetes are a complex group of bacteria present in a wide variety of environments, either as dormant spores or actively growing. Some actinomycetes produce two potent terpenoids (geosmin and 2-methylisoborneol (MIB)) and pyrazines, common causes of drinking water off flavours, and have been implicated in taste and odour episodes. However, isolation from a water source is not evidence that actinomycetes caused a taste and odour event. Dormant spores of actinomycetes may be isolated from aquatic environments in high concentrations, despite production in the terrestrial environment. Similarly, odourous compounds produced by actinomycetes may be produced terrestrially and washed into aquatic environments, with or without the actinomycetes that produced them. Actinomycetes may exist as actively growing mycelium in small, specialized habitats within an aquatic system, but their odourous compounds may influence a wider area. This paper attempts to elucidate the types and activities of actinomycetes that may be found in, or interact with, drinking water supplies.     

Variation in the concentrations of higher alcohols,methanol and ethyl acetate in brandies

86 samples of brandy representing the produce of 15 countries, were analysed for methanol, propan-1-ol, the butanols, the pentanols and ethyl acetate, and wide variations were found between individual samples within each group. The determination of these congeners is not sufficient to identify a sample as a brandy.
