The strategic importance of building highly capable information technology (IT) infrastructure has become a crucial management issue of the 1990s and beyond. However, in spite of the numerous benefits attributed to IT infrastructure, these claims remain unsubstantiated. This problem is due, in part, to inadequate conceptualizations of IT infrastructure and its measurement as well as a lack of t...

This paper presents investigation effects of a sharp edged gust on aeroelastic behavior and time-domain response of a typical section model using Jones approximate aerodynamics for pure plunging motion. Flutter analysis has been done by using p and p-k methods developed for presented finite-state aerodynamic model for a typical section model (airfoil). Introduction of gust analysis as a linear ...

OBJECTIVE To detect and explain changing trends in incidence, case fatality rates, and mortality for unintentional injuries in the Netherlands for the years 1950 through 1995. METHODS Using national registry data, the authors analyzed trends in traffic injuries, occupational injuries, and home and leisure injuries. RESULTS Between 1950 and 1970, mortality from unintentional injuries rose, r...

The relationship of the clavigerite genera Diartiger Sharp and Microdiartiger Sawada is discussed, and the synonymy of the two genera proposed by Besuchet (1986) is followed. This results in two new combinations: D. thinhi (Nomura), comb. n. and D. songxiaobini (Yin & Li), comb. n. Two new species, D. dentatus Yin & Li, sp. n. and D. yaoluopingensis Yin & Li, sp. n. are described from Anhui, Ea...

The effects of sodium bicarbonate concentration, population density, and temperature on the maintenance of an outdoor monoculture of the cyanobacterium Spirulina platensis were studied. A clear response by Spirulina to the concentration of bicarbonate was evident, with 0.2M bicarbonate representing the lowest concentration in which a monoculture could be maintained. When the temperatures fell d...

The activity based cost (ABC) approach has been used to relate costs and benefits to various cost pools that drive product profitability within an organization, so that relationships can be established between investments and product profitability. In this paper, using a particular case, we demonstrate the value of the ABC approach for IT investment justification under certain conditions, and d...

This study aimed to analyze the contributions of the Primary Healthcare nursing interventions, with primiparae in the promotion of breastfeeding. This is a quasi-experimental, longitudinal study, with a sample consisting of 151 primiparae, who had less than 28 weeks of pregnancy, with the child living for at least six months after the birth, performed between 15 October 2007 and 29 February 200...
