Countries with positive per capita real growth are characterised by positive national savings—including government savings, increases in government investment, and strong increases in private savings and investment. On the other hand, countries with negative per capita real growth tend to be characterised by declines in savings and investment. During the past several decades, Kenya’s emerging economy has undergone many changes and economic performance has been epitomised by periods of stability, decline, or unevenness. This article discusses and analyses the record of economic performance and public finance in Kenya during the period 1960‒2010, as well as policies and other factors that have influenced that record in this emerging economy.

For about 45 years, vote and popularity functions have been estimated for many countries, indicating that both voting intentions and actual votes are influenced by economic development. The economy is, of course, not the only and probably not always the most important factor, but there is no doubt anymore that it is an important factor. The most relevant variables are still unemployment and/or real growth, and inflation. The estimated coefficients vary considerably between countries and time periods. In studies done, retrospective sociotropic voting dominates. However, the evidence is not so univocal; rather, it tells that voting has egotropic as well as sociotropic aspects, and it is prospective as well as retrospective. It is still open what roles self-interest and altruism play in voting.

This paper describes a prediction model adopted by the Department of Energy and Resources of Quebec to (i) update temporary sample plots and (ii) project into the future the state of permanent sample plots in Quebec forests. Predicting the growth of a forest species means predicting the state of this species in time. Three basic characteristics mark the state of a species in a given year: number of trees, their total basal area, and their total volume. To date, in Quebec, normal or empirical yield tables have been used to predict the state of some species in ideal or real growth conditions, but these yield tables apply only to pure or almost pure even-aged stands. The prediction model for hardwood and softwood species presented in this paper serves the same purpose as the yield tables; however, it differs from the yield tables in that it can predict the state of each hardwood or softwood species found in pure or mixed, even- or uneven-aged stands. The prediction model was validated for 19 species found in a pilot territory located in the Basse-Gatincau (southwestern Quebec). The paper terminates with a discussion on the limitation of the prediction model and the conditions for its use.

Tartans, from very modest beginnings, have become a real growth industry, with huge commercial implications - over 100 new or unrecorded ones are added to the list each year. That list (already including 2700 entries) is the Register of All Publicly Known Tartans. Crucial to the success of the tartan industry is that each tartan be unique and correctly attributed. This article tells of the Register’s efforts to ensure that this is so, and the role effective indexing (still in the early stages of development) has to play.

After a revision of literature regarding the most up-to-date points of view about the etiopathogenesis of prostatic hyperplasia, i.e. hormonal growth factors, Mac Neal's theory of reawakening, and the theories based on the involvement of staminal cells, the authors report their practical experience on this subject. Since 1989 they have prepared in-vitro cultures, standardized the method and have cultivated cells with different concentrations of testosterone and growth factors. Analyses were by direct observation, with cytologic and immunochemical preparations for morphologic characterization and using the autoradiographic method to determine the Labeling Index. From a preliminary survey of the results it seems that DHT does not affect the multiplication of cells, but influences the differentiation process, becoming an agent of “well-being” and not a real growth factor. EGF would be efficacious only at high dosages with a result of non differentiation and growth of non-mature cells. The estrogens do not increase the succesful percentage of secondary cultures and are therefore, not factors of cellular “well-being”. Finally, data confirm that BPH is not a proliferative disease, as the DNA in replication is limited to about 3% with scarce mitosis.
