period. Of these 14, only three, namely, the Philippines, Thailand and Sri Lanka, appeared at a rough glance, to have met the two balances. In most of the others, the rate of growth of food production, even when keeping abreast of population growth, was not sufficient to accommodate increases in food demand that should be allowed for at normal rates out of additional incomes. Mozambique, Ethiopia and Nicaragua put in a dismal showing with staggering declines in the index of per capita food production, although the reference period straddles the systemic breaks in these countries. India conforms to the general pattern of doing rather better in terms of the overall growth and, therefore, of the labour absorption experience than in terms of the food balance relation. Three conditional conclusions seem to be justified: that it is only in exceptional cases that both balances have been maintained; that in the majority of cases, the experience with regard to overall growth has been better than that for the food sector, implying imbalanced growth; and that in the overwhelming number of cases, the food balance has been grossly violated. A few additional points need to be made. First, the twin balances as discussed only provide a floor level: the balances could also be maintained at much higher growth rates. Second, even when the balances are met, it is possible that other mechanisms operate which lead to the violations of the conditions which the balances were meant to protect. Thus, food production and employment might be sufficient, but if the foodgrains are politically prices (as in India), the result might be similar, from the point of view of the poor, to the situation where the food balance is violated. So also, the rate of employ-ment increase might be high enough, but the labour participation rate might rise for certain groups of the population while it drops for others, again implying, from the point of those left out, a violation of the employment balance. Third, even where one or both balances are violated, it is possible that there is a positive per capita growth rate of income in aggregate terms. Indeed, high per capita growth rates are more likely to be characterised by food imbalances than not. Fourth, these imbalances are partly ascribable to the nature of the growth process, but usually also in part to the nature of planning and policy priorities of the state. What happens when there are imbalances? While the pressures set up by imbalances are similar, the manner in which they are absorbed, and hence the social burden of the adjustment is quite different in socialist as against capitalist economies. When the EB is violated, the average number of dependents per employed person rises. If alongside this, per capita incomes are rising, then the question becomes one of an equitable sharing of the restricted employment opportunities . W ithin a capitalist framework, there is no way for this to happen; in a socialist economy, where the entitlement to work is universally guaranteed, there is an inbuilt redistributive mechanism which shares out the available benefits of employment - albeit with greater gains for the employed - between the employed and the unemployed population. When the FB is broken, then in a capitalist economy, the inequality of the distribution of income leads to an inflationary process which raises the price of food suf-ficiently to establish a new equilibrium, but at a point where the post facto income elasticity of demand for food is low enough to equilibriate effective

The basic aims of this paper are: firstly, to set up an endogenous model of food production per capita and population; secondly, to estimate the food production per capita regression equation and population regression equation; and thirdly, to determine stability properties of food production per capita and population in Asia during the period 1967-1997. Empirical content of this model confirms the fact that movement of food production per capita and population had unstable character in Asia in the observed period.

The Latin American region exhibited an increase in gross domestic product per capita during the 2000s, an improvement in all employment and earnings indicators, and poverty and inequality reductions. On a country-by-country basis, all Latin American countries exhibited positive GDP per capita growth rates during the 2000s. Most countries experienced substantial improvements in labour market conditions over the period, Honduras being the only exception to this general pattern. Finally, the growth rates of most countries in the region were negatively affected by the international crisis of 2008, which also affected several labour market indicators in the worsening direction. Most labour market indicators had fully or partially recovered by 2012–13.

The problem of the Russian economy’s growth rates is considered in the article in the context of Russia’s backwardness regarding GDP per capita in comparison with the developed countries. The author stresses the urgency of modernization of the real sector of the economy and the recovery of the country’s human capital. For reaching these goals short- or mid-term programs are not sufficient. Economic policy needs a long-term (15-20 years) strategy, otherwise Russia will be condemned to economic inertia and multiplying structural disproportions.

In 1792, the French Revolution became a thing in itself, an uncontrollable force that might eventually spend itself but which no one could direct or guide. The governments set up in Paris in the following years all faced the problem of holding together against forces more revolutionary than themselves. This chapter distinguishes two such forces for analytical purposes. There was a popular upheaval, an upsurge from below, sans-culottisme, which occurred only in France. Second, there was the “international” revolutionary agitation, which was not international in any strict sense, but only concurrent within the boundaries of various states as then organized. From the French point of view these were the “foreign” revolutionaries or sympathizers. The most radical of the “foreign” revolutionaries were seldom more than advanced political democrats. Repeatedly, however, from 1792 to 1799, these two forces tended to converge into one force in opposition to the French government of the moment.

This paper examines the empirical relationship between unemployment and real output in the Philippines utilizing quarterly data from the Labor Force Survey by the Philippine Statistics Authority for the period from 1990-2014. The study employed three variants of Okun’s Law – the “gap” approach, the “first difference” approach, and a dynamic approach.   Findings show that the Okun’s coefficients based on the gap approach are consistent with the theoretical expectation of a negative relationship.  In the ARDL model, labor force participation rate and trade openness were found to be significantly related to unemployment. The result of dummy variable test revealed the presence of structural break following the re-definition of unemployment in the Philippines in 2005. Recursive least squares and rolling regressions show evidence of parameter instability in several sub-periods.

Empirical evidence suggests an overall convergence in terms of GDP and per capita income occurring among the European Union (EU) Member States. Nevertheless, economic inequalities have been increasing at the regional level within European Union countries. Through the review of relevant literature, this study analyzes the increasing inequalities from an economical point of view, focusing on Italy and the UK as examples. First, a general overlook of the empirical evidence of the GDP and per capita income at national and sub-national levels will be presented. Second, an explanation of the possible causes of the results will be proposed through the use of economical and sociological theories. The findings of this research might uncover the relative inefficacy of EU Cohesion policies and point towards the necessity for deeper and more thoughtful measures to continue the convergence of Member States while preserving internal equilibria. This paper ends with discussions for the future directions of the EU.


The theory of the vibrations of the pianoforte string put forward by Kaufmann in a well-known paper has figured prominently in recent discussions on the acoustics of this instrument. It proceeds on lines radically different from those adopted by Helmholtz in his classical treatment of the subject. While recognising that the elasticity of the pianoforte hammer is not a negligible factor, Kaufmann set out to simplify the mathematical analysis by ignoring its effect altogether, and treating the hammer as a particle possessing only inertia without spring. The motion of the string following the impact of the hammer is found from the initial conditions and from the functional solutions of the equation of wave-propagation on the string. On this basis he gave a rigorous treatment of two cases: (1) a particle impinging on a stretched string of infinite length, and (2) a particle impinging on the centre of a finite string, neither of which cases is of much interest from an acoustical point of view. The case of practical importance treated by him is that in which a particle impinges on the string near one end. For this case, he gave only an approximate theory from which the duration of contact, the motion of the point struck, and the form of the vibration-curves for various points of the string could be found. There can be no doubt of the importance of Kaufmann’s work, and it naturally becomes necessary to extend and revise his theory in various directions. In several respects, the theory awaits fuller development, especially as regards the harmonic analysis of the modes of vibration set up by impact, and the detailed discussion of the influence of the elasticity of the hammer and of varying velocities of impact. Apart from these points, the question arises whether the approximate method used by Kaufmann is sufficiently accurate for practical purposes, and whether it may be regarded as applicable when, as in the pianoforte, the point struck is distant one-eighth or one-ninth of the length of the string from one end. Kaufmann’s treatment is practically based on the assumption that the part of the string between the end and the point struck remains straight as long as the hammer and string remain in contact. Primâ facie , it is clear that this assumption would introduce error when the part of the string under reference is an appreciable fraction of the whole. For the effect of the impact would obviously be to excite the vibrations of this portion of the string, which continue so long as the hammer is in contact, and would also influence the mode of vibration of the string as a whole when the hammer loses contact. A mathematical theory which is not subject to this error, and which is applicable for any position of the striking point, thus seems called for.

In this paper, we study economic growth and its volatility from an episodic perspective. We first demonstrate the ability of the genetic algorithm to detect shifts in the volatility and levels of a given time series. Having shown that it works well, we then use it to detect structural breaks that segment the GDP per capita time series into episodes characterized by different means and volatility of growth rates. We further investigate whether a volatile economy is likely to grow more slowly and analyze the determinants of high/low growth with high/low volatility patterns. The main results indicate a negative relationship between volatility and growth. Moreover, the results suggest that international trade simultaneously promotes growth and increases volatility, human capital promotes growth and stability, and financial development reduces volatility and negatively correlates with growth.

Abstract Population rise, climate change, soil degradation, water scarcity, and food security require efficient and sustainable food production. Aquaponics is a highly efficient way of farming and is becoming increasingly popular. However, large scale aquaponics still lack stability, standardization and proof of economical profitability. The EU-INAPRO project helps to overcome these limitations by introducing digitization, enhanced technology, and developing standardized modular scalable solutions and demonstrating the viability of large aquaponics. INAPRO is based on an innovation a double water recirculation system (DRAPS), one for fish, and the other one for crops. In DRAPS, optimum conditions can be set up individually for fish and crops to increase productivity of both. Moreover, the integration of digital technologies and data management in the aquaculture production and processing systems will enable full traceability and transparency in the processes, increasing consumers’ trust in aquaculture products. In this paper, the innovations and the digitization approach will be introduced and explained and the key benefits of the system will be emphasized.

In 2000, the World population was 6.2 billion; it reached 7 billion in 2012 and should reach 9.5 billion (±0.4) in 2050 and 11 billion (±1.5) in 2100, according to UN projections. The trend after 2100 is still one of global demographic growth, but after 2060, Africa would be the only continent where the population would still increase. The amount of water consumed annually to produce the food necessary to meet the needs varies greatly between countries, from about 600 to 2,500 m<sup>3</sup>/year per capita, depending on their wealth, their food habits (particularly meat consumption), and the percentage of food waste they generate. In 2000, the total food production was on the order of 3,300 million tons (in cereal equivalents). In 2019, about 0.8 billion inhabitants of the planet still suffer from hunger and do not get the nutrition they need to be in good health or, in the case of children, to grow properly (both physically and intellectually). Assuming a World average water consumption for food of 1,300 m<sup>3</sup>/year per capita in 2000, 1,400 m<sup>3</sup>/year in 2050, and 1,500 m<sup>3</sup>/year in 2100, a volume of water of around 8,200 km<sup>3</sup>/year was needed in 2000, 13,000 km<sup>3</sup>/year will be needed in 2050, and 16,500 km<sup>3</sup>/year in 2100. Will that much water be available on earth? Can there be conflicts related to a food deficit? Some preliminary answers and scenarios for food production will be given from a hydrologist viewpoint.
