the diamondback moth, plutella xylostella (l.) is a serious and economically important pest of cruciferous crops worldwide. the nutritional indices of this pest on four host plants including two canola (slm046 and rgs003) and two cabbage cultivars (green-cornet and glob-master) were determined under laboratory conditions (25 ± 0.5 °c, 65 ± 5% rh and 16: 8 l: d h). the highest relative consumpti...

This paper uses the consumption Euler equation to derive a decomposition of consumption growth into four sources. These are new information and three sources of predictable consumption growth: intertemporal substitution, changes in the preferences for consumption, and incomplete markets for consumption insurance. Using data on the expenditures of households, we implement the decomposition for t...

Previous studies on public policy under relative consumption concerns have ignored the role of leisure comparisons. This paper considers a two-type optimal nonlinear income tax model where people care both about their relative consumption and their relative leisure. Increased consumption positionality typically implies higher marginal income tax rates for both the high-ability and the low-abili...

BACKGROUND Spain shows the highest bladder cancer incidence rates in men among European countries. The most important risk factors are tobacco smoking and occupational exposure to a range of different chemical substances, such as aromatic amines. METHODS This paper describes the municipal distribution of bladder cancer mortality and attempts to "adjust" this spatial pattern for the prevalence...

Prospective associations between quantity and frequency of alcohol consumption and cancer-specific mortality were studied using a nationally representative sample with pooled data from the 1988, 1990, 1991, and 1997-2004 administrations of the National Health Interview Survey (n = 323,354). By 2006, 8,362 participants had died of cancer. Cox proportional hazards regression was used to estimate ...

BACKGROUND Epidemiological studies have suggested an inconsistent relationship between alcohol drinking and risk of all cancer mortality. As far as we know, no meta-analysis has been conducted to explore this issue. PATIENTS AND METHODS We carried out a PubMed search to find relevant articles published before April 2012 in English. Categorical and dose-response meta-analyses were conducted to...
