    Notes: The paper deals with the question whether gatekeepers arise spontaneously (non-hierarchical) or are created by administrative action (hierarchical). The author's approach to the problem relies on the use of a lifecycle model of an organisation devised by Utterback and Abernathy. They distinguish a product-innovation, a transitional and process- innovation (consolidation) phase in the development of an enterprise. The author's hypothesis is that gatekeepers can arise via either route depending on the phase in which enterprise is operating. In the earlier phases the author predicts that gatekeepers will either be absent or non-hierarchical (spontaneous) while in later phases they will be hierarchical (ex-officio).A test of the hypothesis was carried out on R&D engineers in 16 small firms making non-consumer products in Belgium. The investigation involved sociometric analysis of the communication patterns of members of various R&D groups with their group colleagues or with contacts outside the organisation from which a new gatekeeper definition was derived. The author also devised a new means of characterising the innovatory phase of an enterprise.The results are broadly in accordance with the author's hypothesis. The lesson for management of firms about to innovate radically is to set up its structure in such a way that spontaneous communication links cross-cutting formal communication lines are able to flourish.

    Management of technology in traditional industries: a pilot study in ten Belgian companies (1983)

    Notes: Empirical Research about management of innovation has mainly been limited to the Anglo-Saxon world. In this paper the author reports on a pilot study, which is part of a larger project, in ten small and medium-sized Belgian companies, all of them active in rather mature industries. The study concerned aspects of idea generation, problem-solving, project selection, and some organizational aspects of the innovation process. An interesting hypothesis resulting from this study is that innovation is mainly an incremental process along a natural trajectory characteristic for the subindustry to which the company belongs, and that the selection process is for the majority of these companies only a minor problem.

    ZOOPLANKTON COMMUNITIES OF A NEW PUMPED STORAGE RESERVOIR (1982)

    Notes: : Zooplankton colonization was followed for 16 months in Lake Oconee, Georgia, a new pumped storage reservoir. Data were interpreted to identify differences among stations and seasons, as a function of the reservoir's early stage of development and of pumped storage operations. Colonization was rapid, and the zooplankton community was characterized by a high species diversity; approximately 40 rotifer species and 14 cladoceran genera were recorded. Zooplankton density varied along an environmental gradient from riverine to lentic conditions. Rotifer abundance varied from 104-106 individuals/m3, with maxima in the summers Copepod and cladoceran densities ranged from 103 to nearly 105 individuals/m3; maxima for stations other than the dam were observed in the summer and early fall, but high values at the dam station occurred throughout winter 1980. When pumped storage operations began in December 1979, zooplankton densities increased at the dam station. Pumpback decreased the intensity of the environmental gradient from riverine to lentic conditions, and led to a more similar zooplankton community structure throughout the reservoir.

    CHANGES IN PHYSICAL AND CHEMICAL VARIABLES IN A NEW RESERVOIR DUE TO PUMPED STORAGE OPERATIONS (1982)

    Notes: : Information on biologically important physical and chemical variables is presented for Lake Oconee, a newly impounded pumped storage reservoir in Georgia. During its first summer, when no pumping occurred, temperature, oxygen, pH, inorganic nitrogen, and phosphorus were vertically stratified with severe hypolimnetic oxygen depletion. During the second summer, when pumped storage was in operation, more homogenous vertical profiles, generally higher oxygen, and lower dissolved nutrient concentrations were observed. These pumped storage effects were observed at all stations, rather than being confined to the immediate vicinity of the dam.

    An Enzymatic Method for the Determination of Yeast Cell Wall Glucan in Foods (1981)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 46 (1981), S. 0

    Notes: Processed cell wall β-glucans prepared from strains of baker's or brewer's yeast can be used as a thickening agent in aqueous food systems and they provide a fat-like mouthfeel. This article describes an analytical procedure for the determination of the glucan content added to a variety of food products. The method is based on measurement of reducing sugars produced when the food sample, after appropriate pretreatment, is treated with a commercial microbial β-glucanase (Zymolyase) that is specific for the β-linkages present in the glucan polysaccharide of the added yeast cell walls.

    Effects of Added Calcium on Texture and Quality of Canned Jalapeno Peppers (1981)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 46 (1981), S. 0

    Notes: Jalapeno peppers were canned and treated with calcium chloride, calcium hydroxide, and calcium lactate. Concentrations of 0.2, 0.3, and 0.4% of calcium were used. After 3 months of storage time, the peppers were evaluated for texture, quality, and nutritional composition. Calcium hydroxide was an inadequate firming compound in this experiment because of its neutralizing effect on the acid content and the precipitation found in the can after storage. Calcium chloride at a concentration of 0.2% was found to be the most desirable firming compound because under the test conditions it did not impart a bitter taste and because its solubility properties are better than those of calcium lactate. Higher concentrations failed to significantly increase the firmness of peppers. The treatments produced no adverse effects on the flavor or the vitamin and mineral content, with the exception of calcium, in canned jalapeno peppers.

    The influence of elevated nitrate concentration on rate of leaf decomposition in a stream (1983)

    Notes: SUMMARY. 〈list xml:id="l1" style="custom"〉1Leaf decomposition was compared in two streams at the Coweeta Hydrologic Laboratory, North Carolina. U.S.A. One stream drains an undisturbed hardwood watershed, while the other drains a successional watershed subject to an insect outbreak. The successional watershed has elevated nitrate concentrations in the streamwater.2Both black locust (Robinia pseudo-acacia) and sweet birch (Betula lenta) leaf litter decomposed 2.8 times more rapidly in the stream with high nitrate concentrations.3The more rapid decay rates appeared to be partly due to accelerated microbial processing in response to nitrate enrichment, because microbial biomass (as ATP) was higher in the nitrate-enriched stream.4At each point in time, nitrogen and phosphorus content of the litter was lower in the high nitrate stream; however, there was no significant difference in nitrogen or phosphorus content at the same state of leaf decay in the two streams.
