Underrepresentation occurs when a given group is less represented in a subpopulation than they are within the larger population as a whole. In practice, this might mean, for example, a certain ethnicity comprising forty percent of the population, but only ten percent of the CEOs [chief executive officers] in a given country. As another example, imagine ten percent of a country's population has learning differences, but only one percent of that group receives any higher education. 3, record 1, English, - under%2Drepresentation

The mean size(length and weight) of Walleye and age of Walleye has increased, while the increase in catch-per-unit effort of and proportion of Walleye in the total catch suggests an increase in Walleye biomass in the lake. The presence of the strong 1997 year class that reached sexual maturity in 2003 was left to spawn multiple times without considerable harvest has likely helped improve the status of the population. 3, record 6, English, - population%20status

The total mortality rate estimated from the lengths in the scientific surveys, the number of fishing days of a fleet per season, the percentage of immature individuals as well as the amount of gear per fishing area are indicators of fishing pressure on a population. For example, a mean total mortality rate estimated during a period when fishing would not have had an impact on the health of the population can serve as a target reference point. Recommendations aimed at reducing the level of withdrawal can then be issued when this target reference is exceeded. 2, record 7, English, - fishing%20pressure

Certains peuvent servir au développement de points de référence. Par exemple, un taux de mortalité totale moyen estimé au cours d'une période où la pêche n'aurait pas eu d'impact sur la santé de la population peut servir de point de référence cible.

In this analysis, the mean catch per tow at age by stratum was modeled as a function of the age, year-class, and stratum.

Como la mortalidad de los árboles se debe por lo general a factores múltiples e interrelacionados, que van de la sequía a las plagas de insectos y enfermedades, la determinación de una causa de mortalidad única sería poco realista. No obstante, los factores de estrés abiótico son frecuentemente la razón fundamental de las enfermedades de los bosques; y se considera que los factores de estrés ligados al clima juegan un rol preponderante en la aparición de muchos brotes graves de insectos y enfermedades forestales. 2, record 13, Spanish, - mortalidad

mortalidad: La Fundación del Español Urgente (Fundéu BBVA), con el asesoramiento de la Real Academia Española, explica que la palabra "mortalidad" hace referencia a la "tasa de muertes en un tiempo dado, mientras que mortandad es una gran cantidad de muertes causadas por una epidemia u otro desastre." [...] De acuerdo con las definiciones del "Diccionario académico", la mortalidad es la ‘tasa de muertes producidas en una población durante un tiempo dado, en general o por una causa determinada’, mientras que "mortandad" es ‘gran cantidad de muertes causadas por epidemia, cataclismo, peste o guerra’. 3, record 13, Spanish, - mortalidad

Developing Hormosira banksii embryos, used as bioassays in toxicity studies, identified ammonium as a toxicant in secondary treated sewage effluent discharged at Boags Rocks, Victoria, Australia. Ammonium did not affect fertilization but had a significant effect on germination at 48 h and cell division at 72 h with most damage occurring in the first 48 h. Ammonium showed a similar effect as whole effluent(when expressed as mg N l-1 ammonium), sampled in June, September and November 1997, on developing H. banksii embryos. This similarity is further confirmed with comparable EC50(concentration causing an effect on 50% of the population tested) and LOEC(lowest observable effect concentration) values.

Toutefois, il se peut que dans certains cas il ne soit pas possible d'établir une PNEC et il faut alors effectuer une estimation qualitative de la relation dose (concentration)-réponse (effet).

Un désert, par définition, est un pays vide d'habitants; mais on a tendance, quand on parle de désert, à limiter la cause de ce vide d'habitants à la sécheresse. [...] Une bonne définition du désert peut se faire par le quotient de la précipitation par l'évaporation. [...] Une région dans laquelle l'évaporation potentielle excède deux fois les précipitations est un désert. Ceci se traduit par la nature discontinue de la végétation. Enfin, comme autre caractère très important par ses conséquences géologiques, les cours d'eau temporaires des déserts n'arrivent pas à la mer (si on excepte les grands fleuves comme le Nil ou le Colorado, qui arrivent dans le désert avec un volume d'eau considérable). Les matériaux de l'érosion restent donc dans le désert lui-même et sont repris sur place par le vent. Les déserts couvrent environ un quart de la surface de la Terre. 2, record 24, French, - d%C3%A9sert

Asymmetrical Distribution.

A skewed distribution is one that "leans" to one side or the other or which has a few extreme values in either direction. If the extreme values are small, the distribution is skewed to the left, or negatively skewed; if the extreme values are large, the distribution is skewed to the right, or positively skewed(for example, salaries in any population are usually skewed by the high salaries earned by a very few people).

"Boom-and bust" cycles-the term is due to Suneson(1960)-follow from the cyclical failure of VR genes to deter newly evolved pathotypes. Given that an effective VR gene(...) forbids the recognition of any underlying HR, it follows that VR varieties will, on average, have the mean HR of the breeding population. If this is low, as it usually is, then the VR "boom" is followed by the "bust" due to the "vertifolia effect". 1, record 39, English, - boom%2Dand%2Dbust%20cycle

When D=2, the smallest 1/r occurs for N=2 and equals 1/r=2. This value seems unrealistically high, suggesting that Lydall' s model can only hold in hierarchies in which D>2.

In order to make statements about the probability of mean profits or losses after a given number of bets, an assumption must be made about the distribution of returns. Returns are assumed to be normally distributed with population parameters given by their sample estimates. Each series of returns is tested using the Kolmogorov-Smirnov test of normality. In no case can the hypothesis that the returns were drawn from a normal population be rejected at the 90 per cent level. 1, record 43, English, - Kolmogorov%2DSmirnov%20test%20of%20normality

Pour calculer la probabilité que l'on réalise un profit moyen ou une perte moyenne après un certain nombre de paris, il faut d'abord formuler une hypothèse au sujet de la distribution des rendements. On suppose que les rendements sont distribués de façon normale, les paramètres de la population étant donnés par les valeurs estimées à partir de l'échantillon. Chaque série de rendements est ensuite soumise au test de normalité de Kolmogorov-Smirnov. On ne peut en aucun cas rejeter à un seuil de signification de 90% l'hypothèse que les rendements sont tirés d'une population normale. 1, record 43, French, - test%20de%20normalit%C3%A9%20de%20Kolmogorov%2DSmirnov
