Leading Firms As Knowledge Gatekeepers In A Networked Environment, Deogratias Harorimana Mr
Leading Firms As Knowledge Gatekeepers In A Networked Environment, Deogratias Harorimana Mr
Dr Deogratias Harorimana
This chapter introduces the role of the knowledge gatekeeper as a mechanism by which knowledge is created and transferred in a networked environment. Knowledge creation and transfer are essential for building a knowledge based economy. The chapter considers obstacles that inhibit this process and argues that leading firms create a shared socio-cultural context that enables the condivision of tacit meanings and codification of knowledge. Leading firms act as gatekeepers of knowledge through the creation of shared virtual platforms. There will be a leading firm that connects several networks of clients and suppliers may not interact directly with one another, but …

Reflections On Recycling, Pollution And History Or, How To Beat The High Cost Of Living, Richard B. Philp
Reflections On Recycling, Pollution And History Or, How To Beat The High Cost Of Living, Richard B. Philp
Richard B. Philp
Lessons learned during the Great Depression and World War II may have to be relearned. The three Rs (reduce, reuse and recycle) were essential then to individual and national survival. A fourth R, repair, was practised as well. These lessons, if relearned, will stand us in good stead when dealing with the current economic climate as well as with problems of pollution and global warming.
Stress-Induced Attenuation Of Acoustic Startle In Low-Saccharin-Consuming Rats., Clinton Chapman, Nancy Dess, Mitzi Gonzales, Cameryn Garrett
Stress-Induced Attenuation Of Acoustic Startle In Low-Saccharin-Consuming Rats., Clinton Chapman, Nancy Dess, Mitzi Gonzales, Cameryn Garrett
Clinton D Chapman
Exposure to stress can lead to either increased stress vulnerability or enhanced resiliency. Laboratory rats are a key tool in the exploration of basic biobehavioral processes underlying individual differences in the effect of stress on subsequent stressors' impact. The Occidental low (LoS) and high (HiS) saccharin-consuming rats, which differ in emotional reactivity, are useful in this effort. In the present study, footshock affected acoustic startle amplitude 4 h later among LoS but not HiS rats. Surprisingly, shock attenuated startle rather than sensitizing it, a finding not previously reported for male rats exposed to shock. Attenuation was blocked by administering the …

Modelling Tempering Behaviour Of Dark Chocolates From Varying Particle Size Distribution And Fat Content Using Response Surface Methodology, Emmanuel Ohene Afoakwa, Alistair Paterson, Mark Fowler, Joselio Vieira
Professor Emmanuel Ohene Afoakwa
Central Composite Rotatable Design (CCRD) for K=2 was used to study the combined effects of multi-stage heat exchangers for Stages 1 (14–30 °C) and 2 (12–28 °C) coolant temperatures at constant Stage 3 coolant and holding temperatures during tempering of dark chocolates using laboratory-scale mini-temperer. Quantitative data on chocolate temper index (slope) were obtained for products with varying particle size distribution (PSD) (D90 of 18, 25, 35 and 50 μm) and fat (30% and 35%) content. Regression models generated using stepwise regression analyses were used to plot response surface curves, to study the tempering behaviour of products. The results showed …
A Darwinist View Of The Living Constitution, Scott Dodson
A Darwinist View Of The Living Constitution, Scott Dodson
Scott Dodson
The metaphor of a “living" Constitution imports terms from biology into law and, in the process, relies on biology for its meaning. A proper understanding of biology is therefore central to understanding living constitutionalism. Yet despite its rampant use by both opponents and proponents of living constitutionalism, and despite the current fervent debate over whether biology can be useful to the law, no one has evaluated the metaphor from a biological perspective.
This Essay begins that inquiry in an interdisciplinary study of law, science, and philology. The Essay first evaluates the metaphor as it is currently used and concludes that …
Flavor Formation And Character In Cocoa And Chocolate: A Critical Review, Emmanuel Ohene Afoakwa, Alistaiar Paterson, Mark Fowler, Angela Ryan
Flavor Formation And Character In Cocoa And Chocolate: A Critical Review, Emmanuel Ohene Afoakwa, Alistaiar Paterson, Mark Fowler, Angela Ryan
Professor Emmanuel Ohene Afoakwa
Chocolate characters not only originate in flavor precursors present in cocoa beans, but are generated during post-harvest treatments and transformed into desirable odor notes in the manufacturing processes. Complex biochemical modifications of bean constituents are further altered by thermal reactions in roasting and conching and in alkalization. However the extent to which the inherent bean constituents from the cocoa genotype, environmental factors, post-harvest treatment and processing technologies influence chocolate flavor formation and relationships with final flavor quality, has not been clear. With increasing speciality niche products in chocolate confectionery, greater understanding of factors contributing to variations in flavor character would …
Characterization Of Melting Properties In Dark Chocolates From Varying Particle Size Distribution And Composition Using Differential Scanning Calorimetry, Emmanuel Ohene Afoakwa, Alistair Paterson, Mark Fowler, Joselio Vieira
Characterization Of Melting Properties In Dark Chocolates From Varying Particle Size Distribution And Composition Using Differential Scanning Calorimetry, Emmanuel Ohene Afoakwa, Alistair Paterson, Mark Fowler, Joselio Vieira
Professor Emmanuel Ohene Afoakwa
Melting properties in dark chocolates processed from varying particle size distribution (PSD), fat and lecithin content were studied using differential scanning calorimetry (DSC). Compositional parameters were PSD (D90 (90% finer than this size) of 18, 25, 35 and 50 lm), fat (25%, 30% and 35%) and lecithin (0.3% and 0.5%) contents. Variations in PSD had no influence on crystallinity of products. Fat and lecithin content influenced the degree of crystallinity and melting properties (Tend, Tindex and DHmelt) of the products. Increasing fat content caused consistent increases in degree of crystallinity and crystal size distribution, thus effecting significant changes in Tend, …

Improving Productivity In Mixed-Species Plantations, Mila Bristow, J Doland Nichols, Jerome K. Vanclay
Professor Jerome K Vanclay
Mixed species plantations are often promoted as being environmentally preferable to monocultures, but are rarely considered operationally viable by commercial forest growers. Despite many publications documenting benefits demonstrated in research studies (e.g., Kelty 2006; Forrester et al. 2006b; Wood and Vanclay 1995), and despite continuing calls from a wide range of advocates for mixed-species plantations, polyculture remains the exception rather than the rule in industrial plantation forestry (Nichols et al 2006)...

Effects Of Tempering And Fat Crystalization Behaviours On Microstructure, Mechanical Properties And Appearance In Dark Chocolate Systems., Emmanuel Ohene Afoakwa, Alistaiar Paterson, Mark Fowler, Joselio Vieira
Professor Emmanuel Ohene Afoakwa
Fat crystallisation behaviours in dark chocolates from varying particle size distribution (PSD) (D90 of 18, 25, 35 and 50 µm) was studied, yielding products from different temper regimes (optimal temper, over-temper and under-temper), and their effects on mechanical properties and appearance evaluated. Microstructures of derived products were determined using stereoscopic binocular microscopy. Wide variations in mechanical properties and appearance were noted in products from different particle size and temper regimes. Particle size (PS) was inversely related with texture and colour, with the greatest effects noted in hardness, stickiness and lightness at all temper regimes. Over-tempering caused significant increases in product …

Polar Bear Population Forecasts: A Public-Policy Forecasting Audit, J. Scott Armstrong, Kesten C. Green, Willie Soon
J. Scott Armstrong
Calls to list polar bears as a threatened species under the United States Endangered Species Act are based on forecasts of substantial long-term declines in their population. Nine government reports were written to help U.S. Fish and Wildlife Service managers decide whether or not to list polar bears as a threatened species. We assessed these reports based on evidence-based (scientific) forecasting principles. None of the reports referred to sources of scientific forecasting methodology. Of the nine, Amstrup, Marcot, and Douglas (2007) and Hunter et al. (2007) were the most relevant to the listing decision, and we devoted our attention to …

BioTex is an EU funded project aiming to develop textile-based sensors for monitoring biological fluids. In the context of the project, there is a need to develop an effective sample delivery strategy for the wearable biomedical devices. A compact, electroactive switchable membrane would be useful as a valve to control the sample delivery within such devices. A method that employed inherently conducting polymers deposited onto a permeable substrate to form a switchable membrane was investigated [1, 2, 3]. By application of specific voltages, the permeability (pore size) of the membrane can be switched to swollen (expand) and contracted forms, which …

Food Fears: A National Survey On The Attitudes Of Australian Adults About The Safety And Quality Of Food, P. G. Williams, E. Stirling, N. Keynes
Peter Williams
A national telephone survey of a representative sample of 1200 Australian adults was conducted in March 2002 in order to identify the factors of greatest concern to consumers in relation to the safety and quality of food, to measure recent trends in views about hazards in the food supply, to explore beliefs about the safety of additives and to discover whether consumers use food labels to check for ingredients of concern. Forty five percent of Australians responded that they were more concerned about the safety and quality of food than they were five years previously, while only 5% were less …

Peter Williams
Australian retail samples of nine beef, six lamb, four veal and two mutton cuts were purchased from 10 retail outlets (butchers and supermarkets) in different socio-economic areas of Sydney and Melbourne. The lean and fat components were analysed for contents of total and individual fatty acids. The content of total fatty acids was less than 5g/100g edible meat in the lean component of all cuts analysed. Saturated and monounsaturated fatty acids comprised, on average, 40% and 42% respectively of total fatty acids in the lean component of red meat cuts. The saturated fatty acid content of the lean component of …

Serve Sizes Of Grain Based Foods In Australia, P. G. Williams, B. Gibson, N. Smith
Peter Williams
A survey was conducted of the recommended serve sizes used on the labelling of 807 grain based foods sold in Sydney stores in 2000. These values were compared with the serve sizes used in a variety of food selection guides, including the Australian Guide to Health Eating (AGHE). In most food categories there was a great deal of variation in the serve sizes recommended, sometimes up to 20 fold. The most consistent recommendations were for sliced breads, with most manufacturers recommending two slices as a serve, and ready-to-eat breakfast cereals (one cup). The median values for cereal products were mostly …

Food Service Trends In New South Wales Hospitals, 1993-2001, R. Mibey, P. G. Williams
Peter Williams
A survey of the food service departments in 93 hospitals throughout NSW Australia (covering 51% of hospital beds in the state) was conducted using a mailed questionnaire and the results compared with those from similar surveys conducted in 1986 and 1993. Over the past eight years there has been a significant increase in the proportion of hospitals using cook-chill food service production systems, from 18% in 1993 to 42% in 2001 (p<0.001). Hospitals with cook-chill systems had lower staff ratios than those with cook-fresh systems (8.3 vs 6.4 beds/full time equivalent staff; p<0.05), but there was no significant …
